A social distancing reminder is posted on a hallway floor of Nebinger Elementary School in Philadelphia, Friday, March 19. U.S. health officials are relaxing social distancing recommendations for schools, now saying students can sit as close as 3 feet to each other in classrooms. The new Centers for Disease Control and Prevention guidelines, announced Friday, signal the agency's turn away from the 6-foot distancing recommendation that had forced some schools to remove desks, stagger scheduling and take other steps to keep kids apart.
