Should your school be fully open? Here's what the CDC says

Only 4 percent of the nation’s schoolchildren live in counties where coronavirus transmission is low enough for full-time in-person learning without additional restrictions, according to the guidelines established by the Centers for Disease Control and Prevention and an analysis of the agency’s latest figures.

President Biden’s administration has made reopening schools a centerpiece of its coronavirus strategy. And the C.D.C’s recommendations call for every elementary school to be open in some fashion.

But even after drastic drops in the number of new coronavirus cases, few counties in the United States meet the C.D.C.’s thresholds to avoid major restrictions, which are based on both the number of cases and test-positivity rates.
