CDC releases 'cruel' summer camp rules after 60 closed in last year: Masks must be worn indoors and outdoors, no toy sharing and kids must be 3ft apart CDC has been slammed for releasing new guidance for summer camps that require campers to wear masks during outdoor activities According to the CDC, campers should wear masks for sports and athletic activities done outdoors when possible and with the exception of swimming Experts blasted this guidance as 'draconian' with one infectious disease scientist saying requiring kids to wear masks at camps is 'unfair and cruel to our children' Most of the roughly 9,000 overnight camps weathered the storm thanks to federal aid including Paycheck Protection Program loans last year
