CDC suggests not all close contacts need to get tested after coronavirus exposure, alarming experts

The Centers for Disease Control and Prevention revised its guidance for coronavirus testing this week and now says that many people who have been exposed to the virus by being in close contact with someone who later tested positive “do not necessarily need a test” if they are not experiencing symptoms. Experts are expressing concern about the change, noting that people without symptoms are responsible for a large share of transmissions.
