These ideas are wrong. People making such claims ignore the accumulating risk of long COVID, the constellation of long-term health effects caused by infection, in children who may get infected once or twice a year. The condition may already have affected nearly six million kids in the U.S. Children need us to wake up to this serious threat. If we do, we can help our kids with a few straightforward and effective measures.
The spread of the mistaken idea that children have nothing to worry about has had some help from scientists. In 2023 the American Medical Association’s pediatrics journal published a study–which has since been retracted—reporting the rate of long COVID symptoms in kids was “strikingly low” at only 0.4 percent. The results were widely publicized as feel-good news, and helped rationalize the status quo, where kids are repeatedly exposed to SARS-COV-2 in underventilated schools and parents believe they will suffer no serious harm.
In January 2024, however, two scientists published a letter with me explaining why that study was invalid. Some of the errors made it hard to understand how the study survived peer review. For example, the authors claimed to report on long COVID using the 2021 World Health Organization definition, but didn’t properly account for the possibility of new onset and fluctuating or relapsing symptoms, even though that definition and the subsequently released 2023 pediatric one emphasize those attributes. Any child with four symptom-free weeks—even nonconsecutive ones—following confirmed infection was categorized by the study authors as not having long COVID.
In August, the authors of the study retracted it. They did not admit to the errors we raised. But they did admit to new errors, and said these mistakes meant they understated the rate of affected children.
And that rate, according to other research, is quite high. The American Medical Association’s top journal, JAMA, in August published a key new study and editorial about pediatric long COVID. The editorial cites several robust analyses and concludes that, while uncertainty remains, long COVID symptoms appear to occur after about 10 percent to 20 percent of pediatric infections.
If you’re keeping score, that’s as many as 5.8 million affected children in the U.S.—so far. And we know studies and surveys of adults have found that repeat infections heighten the risk of long-term consequences…
