The CDC on Friday revised its guidelines on social distancing in schools, lowering the recommended distance for most students from 6 feet to 3 feet. The guidelines keep the 6-foot recommendation for adults.

The CDC also recommends 6 feet of distance for middle and high schools in communities with high transmission, unless the schools can keep students in individual cohorts during the school day. The guidelines also continue to recommend 6 feet between students when they are eating, or engaging in "high exhalation" activities indoors, such as singing, band, or sports.

In high-transmission communities, the guidelines continue to recommend that extracurricular activities be held only outside.
