Potentially deadly bacteria detected in U.S. soil
, according to a new alert from the Centers for Disease Control and Prevention.
The bacteria, Burkholderia pseudomallei, was found along the Gulf Coast region in southern Mississippi. Typically, the bacteria are in tropical and subtropical climates, especially in parts of Southeast Asia, northern Australia, Central America, South America, Puerto Rico, and the U.S. Virgin Islands.
The bacteria can cause melioidosis, a rare and serious infectious disease that spreads to animals and humans through contact with contaminated soil and water via cuts, wounds, mucous membranes, breathing the bacteria in, or eating or drinking it. Worldwide, the disease is fatal in 10%-50% of those who become infected.
CDC and state officials are investigating the samples to find out how widespread the bacteria are within the United States. So far, modeling suggests that the environmental conditions on the Gulf Coast support the growth of B. pseudomallei.
“It is unclear how long the bacteria has been in the environment and where else it might be found in the U.S.,” according to the CDC statement. “CDC is alerting clinicians throughout the country of this discovery through a national health advisory, reminding them to be aware of the signs and symptoms of melioidosis and to consider melioidosis in patients that present with symptoms of the disease.”
Two unrelated people who live near the Gulf Coast region of Mississippi became sick with melioidosis recently – one in July 2020 and one in May 2022. Neither had traveled outside of the United States. The cases led the CDC and the Mississippi State Department of Health to collect environmental samples and test household products at the patients’ homes in June 2022. Three of the samples taken from soil and puddle water in the 2020 case tested positive for the bacteria.
Genomic sequencing revealed that both patients were infected with the same strain of the bacteria from the Western Hemisphere. They were hospitalized with sepsis due to pneumonia and had known risk factors for melioidosis. Both patients recovered after they were treated with antibiotics.
An average of 12 melioidosis cases are diagnosed in the United States each year, with most in people with recent travel to a country where the bacteria is endemic, or regularly found. Cases have also been linked to contaminated products imported from endemic countries. In late 2021, four cases in four states – Georgia, Kansas, Minnesota, and Texas – were linked to a contaminated aromatherapy spray that was imported, and Walmart issued a recall in November of that year, according to a CDC announcement. Two of the four people died.
Given the small number of cases found in the United States, the CDC believes the risk of melioidosis for the general population continues to be “very low,” and the risk of person-to-person spread is considered “extremely low.” But people who live on the Gulf Coast of Mississippi and who have health conditions that may put them at a higher risk, such as diabetes, chronic kidney disease, chronic lung disease, excessive alcohol use, and immunosuppressive conditions, should protect themselves.
The CDC recommends avoiding contact with soil or muddy water, particularly after heavy rains, and protecting open wounds with waterproof bandages. People should also wear waterproof boots when gardening, working in the yard, or doing agricultural work, which can prevent infection through the feet and lower legs, especially after flooding or storms. People should also wear gloves to protect their hands when working directly with soil.
Melioidosis has a wide range of symptoms, including fever, joint pain, headaches, coughing, chest pain, and belly pain. It can also cause conditions such as pneumonia, abscesses, and blood infections. The disease can infect any organ, including the brain. In most cases, symptoms appear within 1-21 days after exposure, with an average of 7 days after exposure.
The CDC’s health advisory for health professionals and public health officials shows that melioidosis is now considered to be locally endemic in areas of the Gulf Coast region in Mississippi.
“Once well-established in the soil, B. pseudomallei cannot feasibly be removed from the soil,” according to the advisory. “Public health efforts should focus primarily on improving identification of cases so that appropriate treatment can be administered.”

Pandemic tied to misdiagnosis of rare pneumonia
Psittacosis, a rare disease, has been underdiagnosed or misdiagnosed during the COVID-19 pandemic, likely because the symptoms of the disease are similar to COVID-19 symptoms, researchers suggest on the basis of data from 32 individuals.
Diagnosis of and screening for COVID-19 continues to increase; however, cases of atypical pneumonia caused by uncommon pathogens, which presents with similar symptoms, may be missed, wrote Qiaoqiao Yin, MS, of Zhejiang Provincial People’s Hospital, China, and colleagues.
“The clinical manifestations of human psittacosis can present as rapidly progressing severe pneumonia, acute respiratory distress syndrome, sepsis, and multiple organ failure,” but human cases have not been well studied, they say.
In a study published in the International Journal of Infectious Diseases, the researchers reviewed data from 32 adults diagnosed with Chlamydia psittaci pneumonia during the COVID-19 pandemic between April 2020 and June 2021 in China. The median age of the patients was 63 years, 20 were men, and 20 had underlying diseases.
A total of 17 patients presented with fever, cough, and expectoration of yellow-white sputum. At the time of hospital admission, three patients had myalgia, two had headache, and two had hypertension. The patients were originally suspected of having COVID-19.
all of which could be observed in COVID-19 patients as well, the researchers wrote.
Reverse transcription-polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA) testing were used to rule out COVID-19. The researchers then used metagenomic next-generation sequencing (mNGS) to identify the disease-causing pathogens. They collected 18 bronchoalveolar lavage fluid (BALF) samples, 9 peripheral blood samples, and 5 sputum samples. The mNGS identified C. psittaci as the suspected pathogen within 48 hours. Suspected C. psittaci infections were confirmed by endpoint PCR for the BALF and sputum samples and six of nine blood samples, “indicating a lower sensitivity of PCR compared to mNGS for blood samples,” the researchers say. No other potential pathogens were identified.
Psittacosis is common in birds but is rare in humans. C. psittaci is responsible for 1%-8% of cases involving community-acquired pneumonia in China, the researchers note. Although poultry is a source of infection, 25 of the patients in the study did not report a history of exposure to poultry or pigeons at the time of their initial hospital admission. Many patients may be unaware of exposures to poultry, which further complicates the C. psittaci diagnosis, they note.
All patients were treated with doxycycline-based regimens and showed improvement.
The findings were limited by several factors, including the lack of a definitive diagnostic tool for C. psittaci and the lack of convalescent serum samples to confirm cases, the researchers note. In addition, molecular detections for PCR are unavailable in most hospitals in China, they say. The results represent the largest known collection of suspected C. psittaci pneumonia cases and highlight the need for clinician vigilance and awareness of this rare condition, especially in light of the potential for misdiagnosis during the ongoing COVID-19 pandemic, they conclude.
The study received no outside funding. The researchers have disclosed no relevant financial relationships.

Linezolid succeeds against gram-positive bacterial infections in ICU
Approximately 80% of patients in intensive care showed clinical improvement in gram-positive bacterial infections after treatment with linezolid, based on data from more than 300 individuals.
Bacterial infections remain a challenge in the management of critically ill patients, as many gram-positive pathogens have become resistant to multiple drug options, Aijia Ma, MD, of West China Hospital of Sichuan University, and colleagues wrote.
Linezolid has demonstrated effectiveness against MRSA and skin and soft-tissue infections (SSTIs), but its use in critically ill patients with gram-positive infections in the ICU has not been characterized, they said.
In a multicenter, real-world study published in the Journal of Intensive Medicine, the researchers reviewed data from 52 hospitals between June 2018 and December 2019. The study population included 366 patients admitted to the ICU with a clinical or laboratory diagnosis of a gram-positive bacterial infection. Patients were treated with linezolid injections (200 mg/100 mL) and followed up once a day until 48 hours after discontinuing therapy, transferring out of the ICU, or death. Most of the patients (243) were older than 65 years; 90 were aged 18-65 years, and 30 were younger than 18 years. Approximately two-thirds (67%) were men. The primary outcome of clinical efficacy was success (cured or improved).
Linezolid was used as second-line and first-line treatment in 232 (63.4%) and 134 (36.6%) patients, respectively. The most common isolated strain was Staphylococcus aureus (31% MRSA; 12.6% methicillin-susceptible S. aureus [MSSA]) followed by Enterococci (6.7% vancomycin resistant, 9.2% vancomycin susceptible) and Streptococcus pneumoniae (3.4% multidrug resistant, 1.7% non–multidrug resistant).
Overall, 82.2% of patients met the criteria for clinical success; 34 (9.3%) were cured and 267 (73%) improved. Clinical success rates for first-line and second-line linezolid therapy were 79.9% and 83.6%, respectively. Failure rates for linezolid were higher for second-line versus first-line treatment (9.5% vs. 5.2%).
The clinical success rate was highest against MSSA (93.3%), followed by MRSA (83.8%). The average daily linezolid dose was 1,109 mg, and the mean treatment time was 5.1 days.
A total of eight patients (2.2%) reported linezolid-related adverse events, and four patients discontinued the medication because of them; none reported treatment-related serious adverse events. The low incidence of thrombocytopenia in the current study (two patients), compared with previous studies may have been related to avoidance of linezolid for at-risk patients as determined by clinicians, and the relatively short duration of linezolid use, the researchers wrote.
The study findings were limited by several factors, including the observational design and inability to compare the efficacy of different drugs; the small sample size; and the lack of data on drugs used prior to ICU admission, the researchers noted. Other limitations included the low detection rate of gram-positive bacteria and potential underreporting of adverse events.
However, the although clinicians will need to pay close attention to possible side effects and evaluate patient conditions on an individual basis before using linezolid in the clinic, they concluded.
The study was supported by grants from West China Hospital of Sichuan University. The researchers reported no relevant financial relationships.

Single dose of HPV vaccine is ‘game changer,’ says WHO
The World Health Organization’s Strategic Advisory Group of Experts on Immunization (SAGE) has changed the recommendation for vaccines against human papillomavirus (HPV).
From the available evidence, SAGE has concluded that a single dose of vaccine offers solid protection against HPV, comparable to that achieved with two-dose schedules.
This could be a “game-changer for the prevention of the disease,” as it would allow “more doses of the life-saving jab reach more girls,” the WHO declared in a press release.
SAGE recommends updating HPV dose schedules as follows:
- One- or two-dose schedule for the primary target of girls aged 9-14 years.
- One- or two-dose schedule for young women aged 15-20.
- Two doses with a 6-month interval for women older than 21.
The HPV vaccine is highly effective for the prevention of HPV serotypes 16 and 18, which cause 70% of cases of cervical cancer, said Alejandro Cravioto, MD, PhD, SAGE chair, in a statement.
“SAGE urges all countries to introduce HPV vaccines and prioritize multi-age cohort catch up of missed and older cohorts of girls. These recommendations will enable more girls and women to be vaccinated and thus preventing them from having cervical cancer and all its consequences over the course of their lifetimes,” he added.
For individuals who are immunocompromised, including those with HIV, three doses of the vaccine should be given if feasible, and if not, then at least two doses. There is limited evidence regarding the efficacy of a single dose in this group, the advisory group noted.
Policy makers need to make changes
Now that the WHO has deemed that one dose of HPV vaccine is sufficient, policy makers should make changes, say experts in a recent editorial comment published in The Lancet Oncology.
“Policy makers should consider modifying their HPV immunization schedules for girls aged 9-14 years from a two-dose regimen to a one-dose regimen,” wrote Jeff D’Souza, PhD, Institute for Better Health, Trillium Health Partners, Mississauga, Ont., and David Nderitu, PhD, Egerton University, Nakuru County, Kenya.
Policy makers also need to consider reorienting their efforts on cervical cancer screening and treatment, and they should ensure that all girls globally have access to an effective HPV vaccination schedule, they add.
The editorialists also make a radical proposal.
Existing supply constraints of the HPV vaccine at the country level are expected to continue for the next 3 years, and the vast majority of new cervical cancer cases and related deaths occur in low- and middle-income countries (LMICs).
To overcome these problems, they suggest that “high-income countries that currently offer two-dose regimens to girls aged 9-14 years should consider opting for a one-dose vaccination schedule, and give any excess of vaccines to countries in greater need of them.”
Two doses in high-income countries
But it is unclear whether high-income countries are ready to move to a one-dose schedule.
Approached for comment, Maurie Markman, MD, president of medicine and science at Cancer Treatment Centers of America, Philadelphia, told this news organization that while he can’t say for certain, he suspects that the United States will be slower to accept this recommendation for a single dose of HPV vaccine “as a component of a ‘standard-of-care’ approach.”
However, it “might formally acknowledge that if an individual/parent will only accept a single vaccine dose (or ultimately refuses to return for a recommended second dose), this will be considered a favorable outcome, both for the individual and society.
“I do not know if regulatory bodies in the United States will accept the existing studies performed to address the one-dose vaccination strategy to rather dramatically change the approach in our country,” he said. “The issue would be that if a single dose was stated to be a clinically acceptable option in the United States, it would rapidly become the standard approach, and the regulators would want to be as certain as possible that this would not have a negative effect on what is now recognized to be a remarkably safe and effective cancer prevention effort.”
Another expert who was approached for comment, Stephanie V. Blank, MD, professor of gynecologic oncology at the Icahn School of Medicine at Mount Sinai, New York, said: “In higher-resourced countries, two doses are still preferred, as they are more effective than one.
“The modeling on which the SAGE recommendation is based is all from studies in LMICs and other modeling studies,” she added.
At present, the Centers for Disease Control and Prevention recommends a two-dose schedule of HPV vaccines for individuals who receive the first dose before their 15th birthday. The three-dose schedule is recommended for those who receive the first dose on or after their 15th birthday and for people with certain immunocompromising conditions.
Studies have shown that two doses of HPV vaccine given to children aged 9-14 years provide as good or better protection than three doses given to older adolescents or young adults.
But even with a two-dose schedule, the WHO reports that uptake of the vaccine has been slow, and coverage is much lower than their 90% target. In 2020, global coverage with two doses was only 13%.
Factors that have influenced the slow uptake and low coverage of HPV vaccines include supply challenges, programmatic challenges, and costs related to delivering a two-dose regimen to older girls who are not typically included in childhood vaccination programs. The relatively high cost of HPV vaccines has also been problematic, particularly for middle-income countries.
Trials of one-dose schedules
The one-dose vaccine schedule has garnered a lot of interest, with several studies showing efficacy.
The KEN SHE trial, based in Kenya, showed that a single dose of the HPV vaccine was highly effective at preventing oncogenic infection, rivaling the protection offered by multidose regimens. Vaccine efficacy was 97.5% (P < .001) against HPV 16/18 for both the bivalent and monovalent vaccines, which is “comparable to that seen in multidose vaccine trials,” the researchers noted.
A study in India found that efficacy against persistent HPV 16 and 18 infection among participants evaluable for the endpoint was 95.4% for the single dose, 93.1% for the two-dose schedule, and 93.3% for the three-dose series.
Commenting on this trial in India in a recent interview with this news organization, Geoffroy Canlorbe, MD, PhD, of the department of gynecologic and breast surgery and oncology, Pitié-Salpêtrière Hospital, Paris, said the findings from India would need “to be confirmed by other studies.” The results were nonetheless “excellent news for developing countries where there are challenges when it comes to access to vaccination.”
Speaking at the 45th Congress of the French Society for Colposcopy and Cervical and Vaginal Diseases, he emphasized that at this stage, the findings “cannot be extrapolated” to France. HPV vaccination coverage is low in France (it is estimated that the rate is 23.7%, placing the country 28th of 31 countries in Europe), and he recommended continuing with the two- or three-dose schedule for the time being.
“This poor coverage has nothing to do with health care–related logistical or organizational issues; instead, it has to do with people’s mistrust when it comes to vaccination. Here, people who get the first dose get the subsequent ones,” said Dr. Canlorbe. “The very fact of getting two to three doses allows the person’s body to increase the production of antibodies and get a longer-lasting response to the vaccine.”
Ethics of the vaccine
In their editorial, Dr. D’Souza and Dr. Nderitu note that there are ethical considerations with the HPV vaccine that can “help guide deliberations, covering nonmaleficence, beneficence, health equity, stewardship, and solidarity.”
It would be inequitable and unjustifiable, they write, to offer a two-dose regimen to girls aged 9-14 years without also introducing multi-age cohort catch-up campaigns or programs for women who do not have access. “When it comes to an effective HPV vaccination schedule, no woman or girl should be left behind,” they say.
To achieve the goal of eliminating cervical cancer, “countries must ensure that 90% of girls are vaccinated, 70% of women are screened, and 90% of women with precancerous lesions receive treatment and care,” they write. “Given resource constraints, particularly in low-middle income countries, policy makers have a responsibility to ensure that resources are used in an optimal manner that promotes the right to health of all individuals.”
Thus, countries that are lagging far behind in cervical cancer education, screening, and treatment should consider opting for a one-dose regimen for girls aged 9-14 years, as well as using additional resources to close the gap in these other areas.

The World Health Organization’s Strategic Advisory Group of Experts on Immunization (SAGE) has changed the recommendation for vaccines against human papillomavirus (HPV).
From the available evidence, SAGE has concluded that a single dose of vaccine offers solid protection against HPV, comparable to that achieved with two-dose schedules.
This could be a “game-changer for the prevention of the disease,” as it would allow “more doses of the life-saving jab reach more girls,” the WHO declared in a press release.
SAGE recommends updating HPV dose schedules as follows:
- One- or two-dose schedule for the primary target of girls aged 9-14 years.
- One- or two-dose schedule for young women aged 15-20.
- Two doses with a 6-month interval for women older than 21.
The HPV vaccine is highly effective for the prevention of HPV serotypes 16 and 18, which cause 70% of cases of cervical cancer, said Alejandro Cravioto, MD, PhD, SAGE chair, in a statement.
“SAGE urges all countries to introduce HPV vaccines and prioritize multi-age cohort catch up of missed and older cohorts of girls. These recommendations will enable more girls and women to be vaccinated and thus preventing them from having cervical cancer and all its consequences over the course of their lifetimes,” he added.
For individuals who are immunocompromised, including those with HIV, three doses of the vaccine should be given if feasible, and if not, then at least two doses. There is limited evidence regarding the efficacy of a single dose in this group, the advisory group noted.

To gauge monkeypox spread, researchers eye cases in women
As cases of monkeypox continue to mount in the United States and abroad, infectious disease experts are closely monitoring one group of people in particular: women.
So far, the overwhelming majority of cases of the viral disease have been reported in men who have sex with men. But in recent days, officials have learned of a handful of cases in women – possibly indicating that the outbreak may be widening.
Researchers are keeping close tabs on the proportion of cases in women to “assess whether the outbreak is moving away” from networks of men who have sex with men, where most of the initial cases have been identified, according to a briefing from the UK Health Security Agency (UKHSA).
“There is insufficient evidence to support a change in the transmission dynamics,” the agency said. “However, over the last few weeks the proportion of female cases has been increasing, so this trend needs to be monitored closely.”
A global collaboration of researchers and clinicians recently described 528 cases of monkeypox in 16 countries – but none were in women.
Since data collection for that study ended in June, the research group has confirmed cases in women, said study coauthor John P. Thornhill, MD, PhD, consultant physician in sexual health and HIV and clinical senior lecturer at Barts Health NHS Trust and Queen Mary University of London.
“Cases in women have certainly been reported but are currently far less common,” Dr. Thornhill told this news organization.
Although infections in women have been outliers during the current outbreak, they can be severe when they do occur. Several women in England have been hospitalized with severe symptoms.
A similar pattern has been seen in New York City, where just one woman is among the 639 total cases, according to a July 21 report from the city’s health agency.
Researchers have recently published guidance on monkeypox for ob.gyns., maternal-fetal medicine subspecialists, and people who are pregnant or breastfeeding in anticipation of the possibility of more cases in women.
The Centers for Disease Control and Prevention advises that “pregnant, recently pregnant, and breastfeeding people should be prioritized for medical treatment” of monkeypox if needed.
One monkeypox vaccine, Jynneos, can be offered to people who are pregnant or breastfeeding and are otherwise eligible for vaccination on the basis of confirmed or likely contact with cases, ideally within 4 days of exposure. Some people at high risk for exposure, such as laboratory workers, may receive the vaccine preemptively.
Another vaccine, ACAM2000, is contraindicated in people who are pregnant or breastfeeding, according to the CDC.
Transmission dynamics
Investigators have not yet identified substantial spread of monkeypox beyond men who have sex with men, although transmission among household contacts, including women and children, has been reported.
Most initial infections during the current outbreak occurred during sexual activity. But monkeypox can spread through any close contact with skin lesions or body fluids and possibly through touching contaminated items like clothing or linens, according to the CDC. It also may spread from mother to child in utero.
Infected pets have been known to spread the disease as well. A multistate monkeypox outbreak in the United States in 2003 was linked to pet prairie dogs, including in childcare and school settings. That year, 55% of the 71 cases occurred in female patients.
More testing, higher positivity rates in men
Since May, more men than women in the United Kingdom have undergone testing for monkeypox, with 3,467 tests in men versus 447 tests in women. Among those tested, the positivity rate has been far higher in men than in women, 54% versus 2.2%, respectively.
As of July 20, about 0.65% of U.K. cases with known gender were in women. Two weeks prior, about 0.4% were in women.
In all, 13 monkeypox cases in England have been in women, and four had severe manifestations that required hospitalization, according to the UKHSA.
Globally, more than 16,000 monkeypox cases have been reported, according to the World Health Organization. The agency said that it plans to rename the disease to reduce stigma.
Monkeypox and pregnancy
Ob.gyns. are often on the “front line in terms of identifying people with infectious diseases,” said Denise J. Jamieson, MD, MPH, Emory University, Atlanta. Dr. Jamieson coauthored “A Primer on Monkeypox Virus for Obstetrician-Gynecologists,” published in Obstetrics & Gynecology.
“Obstetricians need to be aware of what infectious diseases are circulating and be aware of what is going on in the community,” she said.
With monkeypox, “it is anybody’s guess as to how widespread this is going to be,” Dr. Jamieson said.
“The initial monkeypox cases in the current outbreak have been predominately but not exclusively among men who have sex with men; enhanced transmission in this group may be facilitated by sexual activity and spread through complex sexual networks,” Dr. Thornhill said. “As the outbreak continues, we will likely see more monkeypox infections” outside that group.
“Those working in sexual health should have a high index of suspicion in all individuals presenting with genital and oral ulcers and those with proctitis,” he added.
During previous monkeypox outbreaks, the chain of household transmissions has been short, typically two or three people, said Chloe M. Orkin, MD, professor of HIV medicine at Queen Mary University of London. Dr. Orkin directs the Sexual Health and HIV All East Research (SHARE) Collaborative, which has worked to compile the international case series.
Though monkeypox has mainly been transmitted among men who have sex with men, not all identify as gay and some may also have female and nonbinary partners, Dr. Orkin said.
“Clinicians should bear this in mind when examining any person,” she said.

During previous monkeypox outbreaks, the chain of household transmissions has been short, typically two or three people, said Chloe M. Orkin, MD, professor of HIV medicine at Queen Mary University of London. Dr. Orkin directs the Sexual Health and HIV All East Research (SHARE) Collaborative, which has worked to compile the international case series.
Though monkeypox has mainly been transmitted among men who have sex with men, not all identify as gay and some may also have female and nonbinary partners, Dr. Orkin said.
“Clinicians should bear this in mind when examining any person,” she said.

As cases of monkeypox continue to mount in the United States and abroad, infectious disease experts are closely monitoring one group of people in particular: women.
So far, the overwhelming majority of cases of the viral disease have been reported in men who have sex with men. But in recent days, officials have learned of a handful of cases in women – possibly indicating that the outbreak may be widening.
Researchers are keeping close tabs on the proportion of cases in women to “assess whether the outbreak is moving away” from networks of men who have sex with men, where most of the initial cases have been identified, according to a briefing from the UK Health Security Agency (UKHSA).
“There is insufficient evidence to support a change in the transmission dynamics,” the agency said. “However, over the last few weeks the proportion of female cases has been increasing, so this trend needs to be monitored closely.”
A global collaboration of researchers and clinicians recently described 528 cases of monkeypox in 16 countries – but none were in women.
Since data collection for that study ended in June, the research group has confirmed cases in women, said study coauthor John P. Thornhill, MD, PhD, consultant physician in sexual health and HIV and clinical senior lecturer at Barts Health NHS Trust and Queen Mary University of London.
“Cases in women have certainly been reported but are currently far less common,” Dr. Thornhill told this news organization.
Although infections in women have been outliers during the current outbreak, they can be severe when they do occur. Several women in England have been hospitalized with severe symptoms.
A similar pattern has been seen in New York City, where just one woman is among the 639 total cases, according to a July 21 report from the city’s health agency.
Researchers have recently published guidance on monkeypox for ob.gyns., maternal-fetal medicine subspecialists, and people who are pregnant or breastfeeding in anticipation of the possibility of more cases in women.
The Centers for Disease Control and Prevention advises that “pregnant, recently pregnant, and breastfeeding people should be prioritized for medical treatment” of monkeypox if needed.
One monkeypox vaccine, Jynneos, can be offered to people who are pregnant or breastfeeding and are otherwise eligible for vaccination on the basis of confirmed or likely contact with cases, ideally within 4 days of exposure. Some people at high risk for exposure, such as laboratory workers, may receive the vaccine preemptively.
Another vaccine, ACAM2000, is contraindicated in people who are pregnant or breastfeeding, according to the CDC.
Transmission dynamics
Investigators have not yet identified substantial spread of monkeypox beyond men who have sex with men, although transmission among household contacts, including women and children, has been reported.
Most initial infections during the current outbreak occurred during sexual activity. But monkeypox can spread through any close contact with skin lesions or body fluids and possibly through touching contaminated items like clothing or linens, according to the CDC. It also may spread from mother to child in utero.
Infected pets have been known to spread the disease as well. A multistate monkeypox outbreak in the United States in 2003 was linked to pet prairie dogs, including in childcare and school settings. That year, 55% of the 71 cases occurred in female patients.
More testing, higher positivity rates in men
Since May, more men than women in the United Kingdom have undergone testing for monkeypox, with 3,467 tests in men versus 447 tests in women. Among those tested, the positivity rate has been far higher in men than in women, 54% versus 2.2%, respectively.
As of July 20, about 0.65% of U.K. cases with known gender were in women. Two weeks prior, about 0.4% were in women.
In all, 13 monkeypox cases in England have been in women, and four had severe manifestations that required hospitalization, according to the UKHSA.
Globally, more than 16,000 monkeypox cases have been reported, according to the World Health Organization. The agency said that it plans to rename the disease to reduce stigma.
Monkeypox and pregnancy
Ob.gyns. are often on the “front line in terms of identifying people with infectious diseases,” said Denise J. Jamieson, MD, MPH, Emory University, Atlanta. Dr. Jamieson coauthored “A Primer on Monkeypox Virus for Obstetrician-Gynecologists,” published in Obstetrics & Gynecology.
“Obstetricians need to be aware of what infectious diseases are circulating and be aware of what is going on in the community,” she said.
With monkeypox, “it is anybody’s guess as to how widespread this is going to be,” Dr. Jamieson said.
“The initial monkeypox cases in the current outbreak have been predominately but not exclusively among men who have sex with men; enhanced transmission in this group may be facilitated by sexual activity and spread through complex sexual networks,” Dr. Thornhill said. “As the outbreak continues, we will likely see more monkeypox infections” outside that group.

Fourth patient cleared of HIV after stem cell transplant for blood cancer
MONTREAL – from a naturally HIV-resistant donor, U.S. researchers announced at a meeting of the International AIDS Society.
The man received the transplant nearly 3.5 years ago. Since discontinuation of antiretroviral therapy (ART) more than 17 months ago, he has shown no evidence of HIV-1 RNA rebound and no detectable HIV-1 DNA, reported lead investigator Jana K. Dickter, MD, associate clinical professor in the division of infectious diseases at City of Hope, a Duarte, Calif.–based stem cell transplantation center for patients with blood cancers and patients with HIV/blood cancer.
Known as the City of Hope (COH) patient, he is different from the three previously reported patients in that “he was the oldest person to successfully undergo a stem cell transplant with HIV and leukemia and then achieve remission from both conditions,” Dr. Dickter said during a press briefing for the meeting. “He has been living with HIV the longest of any of the patients to date – more than 31 years prior to transplant – and he had also received the least immunosuppressive preparative regimen prior to transplant,” she added.
She said that, like the three previous patients, known as the Berlin, London, and New York patients, the COH patient received a transplant from a donor with natural resistance to HIV because of a rare CCR5-delta 32 mutation.
Dr. Dickter and her coinvestigators used the term “remission” but went further, suggesting that an “HIV cure is feasible” after transplant, given this and the previous cases.
“It’s a bit early to say the patient is cured, but they are clearly in remission,” said Sharon Lewin, MD, president-elect of the International AIDS Society, which runs the meeting. Nevertheless, Dr. Lewin, professor of medicine at the University of Melbourne and director of the Peter Doherty Institute for Infection and Immunity, in Melbourne, acknowledged that cure is “very likely.”
“Two of the previously reported patients have been off ART for long periods of time – Berlin, 12 years (until Timothy’s death in 2020); London, 4 years – and both had far more extensive investigations to try and find intact virus, including very large blood draws, tissue biopsies, etc. For the New York and now this COH patient, the duration off ART has been much shorter. ... But given the prior cases, it is very likely that the New York and COH patients are indeed cured. But I think it’s too early to make that call, hence my preference to use the word, ‘remission,’ “ she told this news organization.
“Although a transplant is not an option for most people with HIV, these cases are still interesting, still inspiring, and help illuminate the search for a cure,” she added.
Dr. Dickter acknowledged that the complexity of stem cell transplant procedures and their potential for significant side effects make them unsuitable as treatment options for most people with HIV, although she said the COH case is evidence that some HIV patients with blood cancers may not need such intensive pretransplant conditioning regimens.
The COH patient received a reduced-intensity fludarabine and melphalan regimen that had been designed at Dr. Dickter’s center “for older and less fit patients to make transplantation more tolerable,” she said. In addition, the graft-vs.-host disease prophylaxis that the COH patient received included only tacrolimus and sirolimus, whereas the previous patients received additional immunosuppressive therapies, and some also had undergone total body irradiation.
Dr. Dickter has disclosed no relevant financial relationships. Dr. Lewin has relationships with AbbVie, BMS, Esfam, Genentech, Gilead, Immunocore, Merck, Vaxxinity, and Viiv.

AT AIDS 2022
Children and COVID: Many parents see vaccine as the greater risk
New COVID-19 cases rose for the second week in a row as cumulative cases among U.S. children passed the 14-million mark, but a recent survey shows that more than half of parents believe that the vaccine is a greater risk to children under age 5 years than the virus.
In a Kaiser Family Foundation survey conducted July 7-17, 53% of parents with children aged 6 months to 5 years said that the vaccine is “a bigger risk to their child’s health than getting infected with COVID-19, compared to 44% who say getting infected is the bigger risk,” KFF reported July 26.
More than 4 out of 10 of respondents (43%) said that they will “definitely not” get their eligible children vaccinated, while only 7% said that their children had already received it and 10% said their children would get it as soon as possible, according to the KFF survey, which had an overall sample size of 1,847 adults, including an oversample of 471 parents of children under age 5.
Vaccine initiation has been slow in the first month since it was approved for the youngest children. Just 2.8% of all eligible children under age 5 had received an initial dose as of July 19, compared with first-month uptake figures of more than 18% for the 5- to 11-year-olds and 27% for those aged 12-15, based on data from the Centers for Disease Control and Prevention.
The current rates for vaccination in those aged 5 and older look like this: 70.2% of 12- to 17-year-olds have received at least one dose, versus 37.1% of those aged 5-11. Just over 60% of the older children were fully vaccinated as of July 19, as were 30.2% of the 5- to 11-year-olds, the CDC reported on its COVID Data Tracker.
Number of new cases hits 2-month high
Despite the vaccine, SARS-CoV-2 and its various mutations have continued with their summer travels. With 92,000 newly infected children added for the week of July 15-21, there have now been a total of 14,003,497 pediatric cases reported since the start of the pandemic, which works out to 18.6% of cases in all ages, the American Academy of Pediatrics and the Children’s Hospital Association said in their weekly COVID-19 report.
The 92,000 new cases represent an increase of almost 22% over the previous week and mark the highest 1-week count since May, when the total passed 100,000 for 2 consecutive weeks. More recently the trend had seemed more stable as weekly cases dropped twice and rose twice as the total hovered around 70,000, based on the data collected by the AAP and CHA from state and territorial health departments.
A different scenario has played out for emergency department visits and hospital admissions, which have risen steadily since the beginning of April. The admission rate for children aged 0-17, which was just 0.13 new patients per 100,000 population on April 11, was up to 0.44 per 100,000 on July 21. By comparison, the highest rate reached last year during the Delta surge was 0.47 per 100,000, based on CDC data.
The 7-day average of emergency dept. visits among the youngest age group, 0-11 years, shows the same general increase as hospital admissions, but the older children have diverged form that path (see graph). For those aged 12-15 and 16-17, hospitalizations started dropping in late May and into mid-June before climbing again, although more slowly than for the youngest group, the CDC data show.
The ED visit rate with diagnosed COVID among those aged 0-11, measured at 6.1% of all visits on July 19, is, in fact, considerably higher than at any time during the Delta surge last year, when it never passed 4.0%, although much lower than peak Omicron (14.1%). That 6.1% was also higher than any other age group on that day, adults included, the CDC said.

Two distinct phenotypes of COVID-related myocarditis emerge
Researchers from France have identified two distinct phenotypes of fulminant COVID-19–related myocarditis in adults, with different clinical presentations, immunologic profiles, and outcomes.
Differentiation between the two bioclinical entities is important to understand for patient management and further pathophysiological studies, they said.
The first phenotype occurs early (within a few days) in acute SARS-CoV-2 infection, with active viral replication (polymerase chain reaction positive) in adults who meet criteria for multisystem inflammatory syndrome (MIS-A+).
In this early phenotype, there is “limited systemic inflammation without skin and mucosal involvement, but myocardial dysfunction is fulminant and frequently associated with large pericardial effusions. These cases more often require extracorporeal membrane oxygenation [ECMO],” Guy Gorochov, MD, PhD, Sorbonne University, Paris, said in an interview.
The second is a delayed, postinfectious, immune-driven phenotype that occurs in adults who fail to meet the criteria for MIS-A (MIS-A–).
This phenotype occurs weeks after SARS-CoV-2 infection, usually beyond detectable active viral replication (PCR–) in the context of specific immune response and severe systemic inflammation with skin and mucosal involvement. Myocardial dysfunction is more progressive and rarely associated with large pericardial effusions, Dr. Gorochov explained.
The study was published in the Journal of the American College of Cardiology.
Evolving understanding
The findings are based on a retrospective analysis of 38 patients without a history of COVID-19 vaccination who were admitted to the intensive care unit from March 2020 to June 2021 for suspected fulminant COVID-19 myocarditis.
Patients were confirmed to have SARS-CoV-2 infection by PCR and/or by serologic testing. As noted in other studies, the patients were predominantly young men (66%; median age, 27.5 years). Twenty-five (66%) patients were MIS-A+ and 13 (34%) were MIS-A–.
In general, the MIS-A– patients were sicker and had worse outcomes.
Specifically, compared with the MIS-A+ patients, MIS-A– patients had a shorter time between the onset of COVID-19 symptoms and the development of myocarditis, a shorter time to ICU admission, and more severe presentations assessed using lower left ventricular ejection fraction and sequential organ failure assessment scores.
MIS-A– patients also had higher lactate levels, were more likely to need venoarterial ECMO (92% vs 16%), had higher ICU mortality (31% vs. 4%), and a had lower probability of survival at 3 months (68% vs. 96%), compared with their MIS-A+ peers.
Immunologic differences
The immunologic profiles of these two distinct clinical phenotypes also differed.
In MIS-A– early-type COVID-19 myocarditis, RNA polymerase III autoantibodies are frequently positive and serum levels of antiviral interferon-alpha and granulocyte-attracting interleukin-8 are elevated.
In contrast, in MIS-A+ delayed-type COVID-19 myocarditis, RNA polymerase III autoantibodies are negative and serum levels of IL-17 and IL-22 are highly elevated.
“We suggest that IL-17 and IL-22 are novel criteria that should help to assess in adults the recently recognized MIS-A,” Dr. Gorochov told this news organization. “It should be tested whether IL-17 and IL-22 are also elevated in children with MIS-C.”
The researchers also observed “extremely” high serum IL-10 levels in both patient groups. This has been previously associated with severe myocardial injury and an increase in the risk for death in severe COVID-19 patients.
The researchers said the phenotypic clustering of patients with fulminant COVID-19–related myocarditis “seems relevant” for their management.
MIS-A– cases, owing to the high risk for evolution toward refractory cardiogenic shock, should be “urgently” referred to a center with venoarterial ECMO and closely monitored to prevent a “too-late” cannulation, especially under cardiopulmonary resuscitation, known to be associated with poor outcomes, they advised.
They noted that the five patients who died in their series had late venoarterial ECMO implantation, while undergoing multiple organ failures or resuscitation.
Conversely, the risk for evolution to refractory cardiogenic shock is lower in MIS-A+ cases. However, identifying MIS-A+ cases is “all the more important given that numerous data support the efficacy of corticosteroids and/or intravenous immunoglobulins in MIS-C,” Dr. Gorochov and colleagues wrote.
The authors of a linked editorial said the French team should be “commended on their work in furthering our understanding of fulminant myocarditis related to COVID-19 infection.”
Ajith Nair, MD, Baylor College of Medicine, and Anita Deswal, MD, MPH, University of Texas M.D. Anderson Cancer Center, both in Houston, noted that fulminant myocarditis is rare and can result from either of two mechanisms: viral tropism or an immune-mediated mechanism.
“It remains to be seen whether using antiviral therapy versus immunomodulatory therapy on the basis of clinical and cytokine profiles will yield benefits,” they wrote.
“Fulminant myocarditis invariably requires hemodynamic support and carries a high mortality risk if it is recognized late. However, the long-term prognosis in patients who survive the critical period is favorable, with recovery of myocardial function,” they added.
“This study highlights the ever-shifting understanding of the pathophysiology and therapeutic approaches to fulminant myocarditis,” Dr. Nair and Dr. Deswal concluded.

Researchers from France have identified two distinct phenotypes of fulminant COVID-19–related myocarditis in adults, with different clinical presentations, immunologic profiles, and outcomes.
Differentiation between the two bioclinical entities is important to understand for patient management and further pathophysiological studies, they said.
The first phenotype occurs early (within a few days) in acute SARS-CoV-2 infection, with active viral replication (polymerase chain reaction positive) in adults who meet criteria for multisystem inflammatory syndrome (MIS-A+).
In this early phenotype, there is “limited systemic inflammation without skin and mucosal involvement, but myocardial dysfunction is fulminant and frequently associated with large pericardial effusions. These cases more often require extracorporeal membrane oxygenation [ECMO],” Guy Gorochov, MD, PhD, Sorbonne University, Paris, said in an interview.
The second is a delayed, postinfectious, immune-driven phenotype that occurs in adults who fail to meet the criteria for MIS-A (MIS-A–).
This phenotype occurs weeks after SARS-CoV-2 infection, usually beyond detectable active viral replication (PCR–) in the context of specific immune response and severe systemic inflammation with skin and mucosal involvement. Myocardial dysfunction is more progressive and rarely associated with large pericardial effusions, Dr. Gorochov explained.
The study was published in the Journal of the American College of Cardiology.
Evolving understanding
The findings are based on a retrospective analysis of 38 patients without a history of COVID-19 vaccination who were admitted to the intensive care unit from March 2020 to June 2021 for suspected fulminant COVID-19 myocarditis.
Patients were confirmed to have SARS-CoV-2 infection by PCR and/or by serologic testing. As noted in other studies, the patients were predominantly young men (66%; median age, 27.5 years). Twenty-five (66%) patients were MIS-A+ and 13 (34%) were MIS-A–.
In general, the MIS-A– patients were sicker and had worse outcomes.
Specifically, compared with the MIS-A+ patients, MIS-A– patients had a shorter time between the onset of COVID-19 symptoms and the development of myocarditis, a shorter time to ICU admission, and more severe presentations assessed using lower left ventricular ejection fraction and sequential organ failure assessment scores.
MIS-A– patients also had higher lactate levels, were more likely to need venoarterial ECMO (92% vs 16%), had higher ICU mortality (31% vs. 4%), and a had lower probability of survival at 3 months (68% vs. 96%), compared with their MIS-A+ peers.
Immunologic differences
The immunologic profiles of these two distinct clinical phenotypes also differed.
In MIS-A– early-type COVID-19 myocarditis, RNA polymerase III autoantibodies are frequently positive and serum levels of antiviral interferon-alpha and granulocyte-attracting interleukin-8 are elevated.
In contrast, in MIS-A+ delayed-type COVID-19 myocarditis, RNA polymerase III autoantibodies are negative and serum levels of IL-17 and IL-22 are highly elevated.
“We suggest that IL-17 and IL-22 are novel criteria that should help to assess in adults the recently recognized MIS-A,” Dr. Gorochov told this news organization. “It should be tested whether IL-17 and IL-22 are also elevated in children with MIS-C.”
The researchers also observed “extremely” high serum IL-10 levels in both patient groups. This has been previously associated with severe myocardial injury and an increase in the risk for death in severe COVID-19 patients.
The researchers said the phenotypic clustering of patients with fulminant COVID-19–related myocarditis “seems relevant” for their management.
MIS-A– cases, owing to the high risk for evolution toward refractory cardiogenic shock, should be “urgently” referred to a center with venoarterial ECMO and closely monitored to prevent a “too-late” cannulation, especially under cardiopulmonary resuscitation, known to be associated with poor outcomes, they advised.
They noted that the five patients who died in their series had late venoarterial ECMO implantation, while undergoing multiple organ failures or resuscitation.
Conversely, the risk for evolution to refractory cardiogenic shock is lower in MIS-A+ cases. However, identifying MIS-A+ cases is “all the more important given that numerous data support the efficacy of corticosteroids and/or intravenous immunoglobulins in MIS-C,” Dr. Gorochov and colleagues wrote.

Monkeypox: Large study highlights new symptoms
Single ulcers, anal lesions, and mouth sores are all unique symptoms of the current monkeypox outbreak, according to the largest international monkeypox case series to date. These findings underscore the need to broaden case definitions for the disease, researchers say.
“While we expected various skin problems and rashes, we also found that 1 in 10 people had only a single skin lesion in the genital area, and 15% had anal and/or rectal pain,” John Thornhill, MD, PhD, the lead author of the research, said in a press release. Dr. Thornhill is a consultant physician in sexual health and HIV and a clinical senior lecturer at Barts NHS Health Trust and Queen Mary University of London. “These different presentations highlight that monkeypox infections could be missed or easily confused with common sexually transmitted infections such as syphilis or herpes,” he said.
Since April 2022, more than 15,000 cases of monkeypox have been reported in 66 countries where the virus was previously not known to be present. The virus, a less severe cousin of smallpox, is endemic to areas of central and west Africa.
In a study published in the New England Journal of Medicine, researchers reported clinical details and outcomes of 528 monkeypox infections across 16 countries. All the cases were diagnosed between April 27 and June 24, 2022. Ninety-five percent of the cases were suspected to have been transmitted through sexual activity, 98% of patients identified as gay or bisexual men, and 75% of the patients were White. The median age of patients in this case series was 38 years, and 90% of infections occurred in Europe. Forty-one percent of patients were HIV-positive, and 96% of these individuals were receiving antiretroviral therapy. Among patients whose HIV status was negative or unknown, 57% reported using preexposure prophylaxis against HIV. About 3 in 10 (29%) individuals tested positive for concurrent sexually transmitted infections.
Nearly three out of four patients (73%) had anogenital lesions, and 41% had mucosal lesions. Fifty-four patients had one genital lesion, and 64% had fewer than 10 lesions in total. Fever (62%), swollen lymph nodes (56%), lethargy (41%), and myalgia (31%) were commonly reported symptoms prior to the development of the rash. Seventy patients (13%) required hospitalization, most commonly for severe anorectal pain and soft-tissue superinfection. Just 5% of patients received monkeypox-specific treatment: intravenous or topical cidofovir (2%), tecovirimat (2%), and vaccinia immune globulin (<1%).
The study “importantly reinforces our current understanding that the overwhelming majority of cases have been sexually associated, predominantly in men who have sex with men,” Jeffrey Klausner, MD, PhD, an infectious disease specialist at the University of Southern California, Los Angeles, said in an interview with this news organization. He was not involved with the research. “Anyone can get monkeypox, but it is most effectively spread through what we call dense networks – where there is a frequent, close personal contact,” he said. “It just happens that gay men and other men who have sex with men have some of those networks.”
The fact that most lesions are present in the genital and anal region – which is unique to this outbreak – points to transmission of the infection during intimate contact, he noted. Still, there is not enough evidence to suggest that monkeypox is spread through sexual transmission. While most semen samples in the study tested positive for monkeypox viral DNA, it is not known whether there is enough virus present to cause transmission, Dr. Thornhill said. He noted that more research is needed.
Dr. Klausner also emphasized the importance of developing new tests to diagnose monkeypox earlier to prevent spread. The lab test for monkeypox requires a swab from a lesion, but this study showed that most patients had notable symptoms prior to developing the standard rash or lesions, he said. Reliable tests using saliva or throat swabs could help detect infections faster, he noted. Patients are thought to be most contagious when they develop lesions, Dr. Klausner said, so diagnosing patients before this stage would allow them to be isolated sooner.
The California-based lab company Flow Health announced a saliva-based PCR test for monkeypox on July 9, although the Food and Drug Administration cautioned that test results from other sample types beside lesion swabs may be inaccurate. “The FDA is not aware of clinical data supporting the use of other sample types, such as blood or saliva, for monkeypox virus testing,” the agency said in a statement on July 15. “Testing samples not taken from a lesion may lead to false test results.”
Dr. Klausner reports no relevant financial relationships.

Science lags behind for kids with long COVID
Emma Sherman, a 13-year-old girl in Ascot, England, woke up to a dizzying aura of blind spots and flashing lights in her field of vision. It was May 2020, and she also had crippling nausea and headaches. By August, her dizziness was so overwhelming, she couldn’t hold her head up, lying in her mother’s lap for hours, too fatigued to attend school.
The former competitive gymnast, who had hoped to try out for the cheerleading squad, now used a wheelchair and was a shadow of her former self. She had been diagnosed with COVID-induced postural orthostatic tachycardia syndrome, a condition often caused by an infection that results in a higher heart rate, extreme nausea, dizziness, and fatigue.
“I was so into sports before I got long COVID, and afterwards I could barely walk,” Emma said.
Even minor movements sent her heart rate sky-high. Her long chestnut hair turned gray and fell out in clumps. In the hospital, she was pricked and prodded, her blood tested for numerous conditions.
“They ran every scan known to man and took an MRI of her brain,” said Emma’s mother, Marie Sherman. “All was clear.”
Emma’s pediatrician determined that the teen had long COVID after having had a mild case of the virus in March, about 2 months before her puzzling symptoms began. But beyond a positive antibody test, doctors have found little evidence of what was causing Emma’s symptoms.
For Emma and others with long COVID, there are no medications shown to directly target the condition. Instead, caregivers target their symptoms, which include nausea, dizziness, fatigue, headaches, and a racing heart, said Laura Malone, MD, codirector of the Johns Hopkins Kennedy Krieger Pediatric Post–COVID-19 Rehabilitation Clinic in Baltimore.
“Right now, it’s a rehabilitation-based approach focused on improving symptoms and functioning so that kids can go back to their usual activities as much as possible,” she says.
Depression and anxiety are common, although doctors are struggling to figure out whether COVID is changing the brain or whether mental health symptoms result from all the life disruptions. There’s little research to show how may kids have depression because of long COVID. Dr. Malone said about half of her patients at the Kennedy Krieger Institute›s long COVID clinic are also dealing with mental health issues.
Patients with headaches, dizziness, and nausea are given pain and nausea medications and recommendations for a healthy diet with added fruits and vegetables, monounsaturated fats, lower sodium, unprocessed foods, and whole grains. Kids with irregular or racing heart rates are referred to cardiologists and potentially prescribed beta-blockers to treat their heart arrhythmias, while children with breathing problems may be referred to pulmonologists and those with depression to a psychiatrist.
Still, many patients like Emma go to their doctors with phantom symptoms that don’t show up on scans or blood tests.
“We’re not seeing any evidence of structural damage to the brain, for example,” said Dr. Malone. “When we do MRIs, they often come out normal.”
It’s possible that the virus lingers in some patients, said Rajeev Fernando, MD, an infectious disease specialist and a fellow at Harvard Medical School, Boston. Kids’ strong immune systems often fend off problems that can be noticed. But on the inside, dead fragments of the virus persist, floating in hidden parts of the body and activating the immune system long after the threat has passed.
The virus can be in the gut and in the brain, which may help explain why symptoms like brain fog and nausea can linger in children.
“The immune system doesn’t recognize whether fragments of the virus are dead or alive. It continues to think it’s fighting active COVID,” said Dr. Fernando.
There is little data on how long symptoms last, Dr. Fernando said, as well as how many kids get them and why some are more vulnerable than others. Some research has found that about 5%-15% of children with COVID may get long COVID, but the statistics vary globally.
“Children with long COVID have largely been ignored. And while we’re talking about it now, we’ve got some work to do,” said Dr. Fernando.
As for Emma, she recovered in January of 2021, heading back to school and her friends, although her cardiologist advised her to skip gym classes.
“For the first time in months, I was feeling like myself again,” she said.
But the coronavirus found its way to Emma again. Although she was fully vaccinated in the fall of 2021, when the Omicron variant swept the world late that year, she was infected again.
“When the wave of Omicron descended, Emma was like a sitting duck,” her mother said.
She was bedridden with a high fever and cough. The cold-like symptoms eventually went away, but the issues in her gut stuck around. Since then, Emma has had extreme nausea, losing most of the weight she had gained back.
For her part, Ms. Sherman has found solace in a group called Long COVID Kids, a nonprofit in Europe and the United States. The group is raising awareness about the condition in kids to increase funding, boost understanding, and improve treatment and outcomes.
“There’s nothing worse than watching your child suffer and not being able to do anything about it,” she said. “I tell Emma all the time: If I could just crawl in your body and take it, I would do it in a second.”
Emma is hoping for a fresh start with her family’s move in the coming weeks to Sotogrande in southern Spain.
“I miss the simplest things like going for a run, going to the fair with my friends, and just feeling well,” she said. “I have a long list of things I’ll do once this is all done.”

It’s possible that the virus lingers in some patients, said Rajeev Fernando, MD, an infectious disease specialist and a fellow at Harvard Medical School, Boston. Kids’ strong immune systems often fend off problems that can be noticed. But on the inside, dead fragments of the virus persist, floating in hidden parts of the body and activating the immune system long after the threat has passed.
The virus can be in the gut and in the brain, which may help explain why symptoms like brain fog and nausea can linger in children.
“The immune system doesn’t recognize whether fragments of the virus are dead or alive. It continues to think it’s fighting active COVID,” said Dr. Fernando.
There is little data on how long symptoms last, Dr. Fernando said, as well as how many kids get them and why some are more vulnerable than others. Some research has found that about 5%-15% of children with COVID may get long COVID, but the statistics vary globally.
“Children with long COVID have largely been ignored. And while we’re talking about it now, we’ve got some work to do,” said Dr. Fernando.
As for Emma, she recovered in January of 2021, heading back to school and her friends, although her cardiologist advised her to skip gym classes.
“For the first time in months, I was feeling like myself again,” she said.
But the coronavirus found its way to Emma again. Although she was fully vaccinated in the fall of 2021, when the Omicron variant swept the world late that year, she was infected again.
“When the wave of Omicron descended, Emma was like a sitting duck,” her mother said.
She was bedridden with a high fever and cough. The cold-like symptoms eventually went away, but the issues in her gut stuck around. Since then, Emma has had extreme nausea, losing most of the weight she had gained back.
For her part, Ms. Sherman has found solace in a group called Long COVID Kids, a nonprofit in Europe and the United States. The group is raising awareness about the condition in kids to increase funding, boost understanding, and improve treatment and outcomes.
“There’s nothing worse than watching your child suffer and not being able to do anything about it,” she said. “I tell Emma all the time: If I could just crawl in your body and take it, I would do it in a second.”
Emma is hoping for a fresh start with her family’s move in the coming weeks to Sotogrande in southern Spain.
“I miss the simplest things like going for a run, going to the fair with my friends, and just feeling well,” she said. “I have a long list of things I’ll do once this is all done.”

Emma Sherman, a 13-year-old girl in Ascot, England, woke up to a dizzying aura of blind spots and flashing lights in her field of vision. It was May 2020, and she also had crippling nausea and headaches. By August, her dizziness was so overwhelming, she couldn’t hold her head up, lying in her mother’s lap for hours, too fatigued to attend school.
The former competitive gymnast, who had hoped to try out for the cheerleading squad, now used a wheelchair and was a shadow of her former self. She had been diagnosed with COVID-induced postural orthostatic tachycardia syndrome, a condition often caused by an infection that results in a higher heart rate, extreme nausea, dizziness, and fatigue.
“I was so into sports before I got long COVID, and afterwards I could barely walk,” Emma said.
Even minor movements sent her heart rate sky-high. Her long chestnut hair turned gray and fell out in clumps. In the hospital, she was pricked and prodded, her blood tested for numerous conditions.
“They ran every scan known to man and took an MRI of her brain,” said Emma’s mother, Marie Sherman. “All was clear.”
Emma’s pediatrician determined that the teen had long COVID after having had a mild case of the virus in March, about 2 months before her puzzling symptoms began. But beyond a positive antibody test, doctors have found little evidence of what was causing Emma’s symptoms.
For Emma and others with long COVID, there are no medications shown to directly target the condition. Instead, caregivers target their symptoms, which include nausea, dizziness, fatigue, headaches, and a racing heart, said Laura Malone, MD, codirector of the Johns Hopkins Kennedy Krieger Pediatric Post–COVID-19 Rehabilitation Clinic in Baltimore.
“Right now, it’s a rehabilitation-based approach focused on improving symptoms and functioning so that kids can go back to their usual activities as much as possible,” she says.
Depression and anxiety are common, although doctors are struggling to figure out whether COVID is changing the brain or whether mental health symptoms result from all the life disruptions. There’s little research to show how may kids have depression because of long COVID. Dr. Malone said about half of her patients at the Kennedy Krieger Institute›s long COVID clinic are also dealing with mental health issues.
Patients with headaches, dizziness, and nausea are given pain and nausea medications and recommendations for a healthy diet with added fruits and vegetables, monounsaturated fats, lower sodium, unprocessed foods, and whole grains. Kids with irregular or racing heart rates are referred to cardiologists and potentially prescribed beta-blockers to treat their heart arrhythmias, while children with breathing problems may be referred to pulmonologists and those with depression to a psychiatrist.
