The science is in. The CDC says that kids should be in school and may in fact be safer in school.
"On Tuesday, federal health officials weighed in with a call for returning children to the nation’s classrooms as soon as possible, saying the “preponderance of available evidence” indicates that in-person instruction can be carried out safely as long as mask-wearing and social distancing are maintained. "
Even though the pandemic is rapidly changing, and contagious new variants are spreading, Dr. Honein and other C.D.C. officials argued there is little evidence that schools spark the kind of outbreaks seen in nursing homes and meatpacking plants, or contribute to increased transmission in communities.
C.D.C. researchers also took a look at 17 elementary and secondary schools in rural Wisconsin where mask-wearing was routine. The incidence of infection was lower in schools than in the community at large, the scientists found. During 13 weeks in the fall of 2020, there were 191 infections among staff and students; only seven resulted from in-school transmission, according to the study.
