It still remains unclear how easily kids are able to spread COVID-19. The Centers for Disease Control and Prevention on Thursday released a long-awaited update to guidelines for getting children back into the classroom this fall, but it left many details of how to do so safely up to officials at the local level. "Let the individual jurisdictions see how the different strategies that we've put out can be best employed," Dr. Robert Redfield, director of the CDC, said during a call with reporters Friday. There's no question that in-person learning is important to the growth and development of children. The question is how to do so safely. "Children get much more than academics at school," members of the American Academy of Pediatrics, the American Federation of Teachers, the National Education Association and The School Superintendents Association wrote this month in a joint statement. "They also learn social and emotional skills at school, get healthy meals and exercise, mental health support and other services that cannot be easily replicated online."
