Young children typically are "superspreaders" of respiratory germs, so it's puzzling that they don't seem to be major transmitters of the coronavirus that causes COVID-19. They're also relatively absent among hospitalized patients.
Initially, that was thought to be because they're less likely to become seriously ill if infected. Later studies indicate that those of primary school age, at least, may be less likely to catch the virus in the first place. Still, they're not immune to an array of indirect COVID-19 harms, including physical abuse, learning gaps, anxiety and depression stemming from school closures, social isolation and other stress-inducing consequences of the pandemic. That's informing considerations for how to safely keep kids in school.
