(Press-News.org) Infants, toddlers and preschoolers exhibit symptoms of long COVID, but the symptoms can be different and more difficult to identify in these children, according to Rutgers Health research.
The new study is part of the National Institutes of Health–funded Researching COVID to Enhance Recovery (RECOVER) initiative and published in the Journal of the American Medical Association Pediatrics.
Lawrence Kleinman, a professor and vice chair of the Department of Pediatrics at Rutgers Robert Wood Johnson Medical School and a professor of global public health at Rutgers School of Public Health, is the lead investigator for the Collaborative Long-term study of Outcomes of COVID-19 in Kids (CLOCK), a national consortium led by Rutgers.
“The COVID pandemic began with a myth – that children are spared its ill effects. In contrast, many children were sick with COVID, and we now have a new chronic illness emerging,” Kleinman said. “We are working hard to characterize long COVID in children and it will be critical for policymakers to assure that we have adequate resources to support and manage these children now and in the future.”
Of the total 1,011 children included in the study, 472 were infants and toddlers (children 2 years old or younger) and 539 were preschoolers (children 3 to 5 years old). Overall, 101 (15%) of the 677 children with previous SARS-CoV-2 infection were identified as likely having long COVID. The symptoms of long COVID in these age groups differ from those reported among school age children and teens. Infants and toddlers with long COVID were more likely to experience difficulty sleeping, fussiness, poor appetite, stuffy nose and coughing while preschoolers were more likely to experience coughing and daytime tiredness and low energy.
Researchers said they can confirm that younger children can have long COVID. Clinicians and caregivers may not recognize long COVID in these children because they are unfamiliar with it. The authors explain too that the inability of younger children to describe how they feel may make identification of long COVID more difficult in this age group. For similar reasons it is important for pediatricians and family physicians to consider long COVID when children present with the symptoms described. The failure to diagnose long COVID quickly delays treatment and inhibits availability of supportive services to children with long COVID.
“This study is the largest systematic look at long COVID in younger children in the United States,” said Sunanda Gaur, a professor of pediatrics and director of the Adult and Pediatric Clinical Research Centers at Robert Wood Johnson University Hospital. “It suggests that this is an illness that children, families, pediatricians and the health care and educational system will be dealing with for a generation.”

Utah engineers develop novel material that efficiently removes ‘forever chemicals’
2025-07-23
University of Utah researchers have developed a material that addresses an urgent environmental challenges: the efficient removal and real-time detection of perfluorooctanoic acid (PFOA), a toxic and persistent member of the PFAS “forever chemicals” family, from contaminated water.
In an industry-funded study published in the Journal of Materials Chemistry C, Ling Zang, professor in the John and Marcia Price College of Engineering’s Department of Materials Science and Engineering, and his research team introduced a dual-functional metal-organic framework (MOF) known as UiO-66-N(CH₃)₃⁺, a zirconium-based material known ...
Study documents unhealthy noise in Portland, provides research framework for other cities
2025-07-23
CORVALLIS, Ore. – A groundbreaking study led by Oregon State University scientists shows that multiple Portland neighborhoods have levels of noise that are likely unhealthy.
The research, the first of its kind in the United States, provides a framework for studying noise pollution in other cities in the U.S., which lags behind European nations in examining the effects of noise on human health.
The project directed by assistant professor Matthew Bozigar and graduate student Carson Mowrer of the OSU College of Health indicates that the loudest parts of Portland are also the most socially vulnerable, with lower incomes and higher proportions ...
Study lays groundwork for preventing dangerous falls on dry spills
2025-07-23
TUCSON, Ariz. — Signs reading “slippery when wet” frequently warn about the dangers of slipping and falling. But floors made slick by dry spills are also a significant hazard – one that’s overlooked and understudied, according to University of Arizona Health Sciences researchers who developed a new way to assess floor slipperiness caused by dry contaminants.
“Most people think materials like oil or soapy water are the main cause of slips,” said study lead Jonathan Lee-Confer, PhD, an assistant professor of physical therapy in the School of Health Professions at the U of A Mel and Enid Zuckerman College ...
Many high street health tests are unfit-for-purpose and need greater regulation, warn experts
2025-07-23
Many self-tests available on the UK high street are unfit-for-purpose and need much greater regulation to ensure they are safe and reliable, conclude two studies published by The BMJ today.
The findings show that most self-tests lack essential information about who should use them, how to interpret the results, and what actions to take next. Some also contradict evidence-based guidance, “creating risks for misinterpretation and inappropriate healthcare decisions,” say the authors.
Self-testing is increasingly popular, with a wide range of tests available to UK consumers without needing healthcare professional involvement. The ...
The Lancet Public Health: Aiming for 7,000 daily steps can reduce risk of chronic diseases, cognitive decline, and death, finds new study
2025-07-23
A comprehensive new study analysing data from over 160,000 adults finds that walking approximately 7,000 steps per day is associated with reductions in the risk of several serious health outcomes, including all-cause mortality (47% reduction), cardiovascular disease (25% reduction), cancer (6% reduction), type 2 diabetes (14% reduction), dementia (38% reduction), depression (22% reduction), and falls (28% reduction).* Unlike earlier studies that mainly focused on heart health or overall death rates, this research, published ...
Stopping HRT leads to a period of higher risk of bone fracture for most women
2025-07-23
A new study has found that the bone fracture protection women get from menopausal hormone therapy (MHT, also known as HRT) disappears within a year of stopping treatment.
In the new study, published in Lancet Healthy Longevity, experts from the School of Medicine at the University of Nottingham, also found that in most cases, stopping treatment is then followed by some years of elevated fracture risk compared to women who have never used MHT. Fracture risks then falls to be similar to, and then lower than women who have never used ...
Rethink the 10,000 a day step goal, study suggests
2025-07-23
Walking 7000 steps a day can lower the risk of an early death by up to 47 percent
Health benefits increased with every 1000-step increment up until 7000 steps, at which point the benefits began to taper off
A major new study led by the University of Sydney suggests that walking 7000 steps a day offers similar health benefits across several outcomes as walking 10,000.
Led by Professor Melody Ding from the School of Public Health, the study was published in The Lancet Public Healthand analysed data from 57 studies from ...
New play in the chemical-reaction playbook uncovered
2025-07-23
UNIVERSITY PARK, Pa. — Speeding up chemical reactions is key to improving industrial processes or mitigating unwanted or harmful waste. Realizing these improvements requires that chemists design around documented reaction pathways. Now, a team of Penn State researchers has found that a fundamental reaction called oxidative addition can follow a different path to achieve the same ends, raising the question of whether this new order of events has been occurring all along and potentially opening up new space for chemical design.
A paper describing the research appeared in the Journal of the American Chemical ...
Fungicides intended to suppress turfgrass diseases may damage fairways
2025-07-23
UNIVERSITY PARK, Pa. — Golf course managers have much more insight into which fungicides to use to suppress turfgrass diseases, such as the common and costly dollar spot disease, without damaging the grass on their fairways, thanks to a new study by researchers at Penn State.
The team evaluated variation in turfgrass injury caused by nine commercially available demethylation inhibitor (DMI) fungicides — a class of fungicide widely used in turfgrass management — commonly used ...
Measuring how – and where – Antarctic ice is cracking with new data tool
2025-07-23
UNIVERSITY PARK, Pa. — A total collapse of the roughly 80-mile-wide Thwaites Glacier, the widest in the world, would trigger changes that could lead to 11 feet of sea-level rise, according to scientists who study Antarctica. To better predict fractures that could lead to such a collapse — and to better understand the processes driving changes in Antarctic ice shelves — a team led by researchers at Penn State developed a new method to evaluate cracks that destabilize ice shelves and accelerate those losses.
They reported ...
