Here’s a list of California counties that were on the state’s coronavirus watchlist as of July 17. Schools in these counties, which are hard hit by the coronavirus, must begin fall classes teaching students remotely online, rather than allowing them to return to classrooms, according to Gov. Gavin Newsom.

Schools can begin teaching in classrooms only when the county is off the watch list for 14 days. Thirty-two of California’s 58 counties are on the list, according to Newsom, who unveiled a series of rules that determine when students can return to classrooms and the measures schools must take to prevent the spread of COVID-19 and deal with any cases that occur.
