As more adults are vaccinated, schools will be one of the few places the virus can still spread easily
CHILDREN IN MANY countries will soon swap their video games and swimming costumes for books and uniforms when they return to classrooms after the summer holidays. School closures have been one of the most common policies to curb the spread of covid-19—and one of the most contentious.
In England, for instance, between May 20th and June 7th, schools were open, the country’s vaccination programme was well under way and the ultra-contagious Delta variant became the dominant strain. During that period the proportion of children between five and 12 testing positive for the virus was five times that of the over-65s. This could be due to increased testing in schools, or because children were mixing more than adults as lockdown rules eased.
Many governments have said that closing schools should be a last resort to contain further covid-19 waves. This is because the costs in learning are. How much transmission of the virus in schools contributes to an epidemic wave can be difficult to assess—it depends on a number of things including the number of cases in the community . But as more adults are vaccinated, schools will be one of the few places the virus can still spread easily.
