Governments in the U.S. and across the world are trying to figure out how to reopen schools during a coronavirus pandemic. In Europe, millions of children are returning to classrooms, turning the continent into a giant lab for what works and what doesn’t.
Here is what we know and don’t know about children and Covid-19, what measures schools in Europe are taking, and what we might find out.
What does science tell us about how children can become infected?
Anyone with children knows that the younger they are, the more likely they are to catch whatever pathogen they come into contact with. But the new coronavirus is different. Most doctors agree that children who catch Covid-19 rarely become seriously ill. How broadly they can spread the virus—and whether they are less susceptible to infections than adults—are still contested issues among scientists.
The World Health Organization has said early research suggests children don’t appear to be spreading the new coronavirus as often as adults, perhaps because younger patients rarely display severe symptoms and so tend to cough and sneeze less than older ones.
French Education Minister Jean-Michel Blanquer told The Wall Street Journal that the latest studies indicate that children below 10 are less contagious than those who are older.
However, Christian Drosten, head of the virology department at Berlin’s Charité clinic, last week warned about reopening schools after finding that a sample of infected children treated at his hospital carried the same viral load as adults.
