The role children, and consequently schools, play in the COVID-19 pandemic has been hard to work out, but that puzzle is now finally starting to be solved.
The latest research shows infections in children frequently go undetected, and that children are just as susceptible as adults to infection. Children likely transmit the virus at a similar rate to adults as well.
While children are thankfully much less likely than adults to get seriously ill, the same isn’t true for the adults that care for them. Evidence suggests schools have been a driver of the second wave in Europe and elsewhere. This means the safety of schools needs an urgent rethink.
Infections with SARS-CoV-2, the virus that causes COVID-19, in children are generally much more mild than in adults and easy to overlook. A study from South Korea found the majority of children had symptoms mild enough to go unrecognised, and only 9% were diagnosed at the time of symptom onset.
