Most of California’s schools could remain shuttered for the rest of the school year as the coronavirus pandemic continues to spread across the state, Gov. Gavin Newsom warned Tuesday.

More than 98 percent of California’s student body — about 6.1 million students — have had their classes cancelled so far, Newsom said. While many school districts have only announced closures for a few weeks, Newsom said it was unlikely that most would open again before their summer breaks in May or June.
