02:36

NBC senior medical correspondent Dr. John Torres joins TODAY to talk about new CDC guidance saying that people who’ve been exposed to the coronavirus but aren’t showing symptoms needn’t be tested. “There’s a lot of consternation in the public health community,” he says, because of the threat of “silent spreaders” who don’t have symptoms. He also talks about a new antigen test authorized by the FDA, saying “it can be a screening tool.”
