The US Centers for Disease Control and Prevention has loosened its guidelines to allow health care workers who have been exposed to COVID-19 to continue working as long as they wear a mask, according to CNN's Dr. Sanjay Gupta.
"This is a huge concern, John, because this is how you potentially increase the spread, at least not slow down the spread," Gupta said to CNN's John Berman this morning.
Within the guidelines, the CDC says bandanas and scarves could be used in place of a mask, Gupta said. The reason for these guidelines is due to a lack of personal protective equipment and not enough health care workers, Gupta said.
