Schools Rethink Covid Rules. We re Over-Quarantining Kids Like Crazy. – WSJ

There s been a tremendous failure of data on this, said Brown University economist Emily Oster, who has studied Covid-19 and schools and said authorities often overreacted to the few cases that appeared in schools. In early September, she organized a team of data scientists to track confirmed cases in schools across the country.

The effort, which has grown to track more than 9,000 schools and more than four million students doing in-person learning nationwide, found a biweekly infection rate of 0.22% among students and 0.42% among staff as of early November. The rate equates to 1.1 children and 2.1 staffers infected per 1,000 each week. The project s preliminary results indicate that nationwide, students who attend school are infected at a rate that is 27% lower than the case rate of communities they live in.
