He and his colleagues have been taking blood samples from secondary-school children in Dresden since May 2020 to track rates of infection. In March and April this year, surveys were taken from more than 1,500 children — nearly 200 of whom had antibodies indicating previous SARS-CoV-2 infection — to see how many reported long COVID.
In May, Armann’s group reported in a preprint that it found no difference in rates of symptoms reported by the two groups3. “This was kind of striking,” says Armann, and suggests that long COVID in children is probably lower than some studies have indicated. That doesn’t mean that long COVID doesn’t exist in children, he says, but it does mean the number is probably below 10%, a level that would have been picked up in the study. The true figure is perhaps as low as 1%, he says.
