New York City should follow the example of affected jurisdictions around the region, the nation and even the world and close public schools.

We understand the immense disruption this will create for our families. But right now more than a million students and staff crisscross the city every day on their way to schools, putting themselves and others at risk of exposure and increasing the likelihood of bringing exposure into their homes and communities.

We must find ways to keep our children safe and to see that they are fed. We must do all we can to help ensure that our students can continue to learn. But we have reached the point where continuing to keep our classrooms open poses a greater lasting threat than the disruption that will result from school closings.
