This makes no sense. 
Updated CDC guidelines now say people exposed to coronavirus may not need to be tested.
In a shift that perplexed some doctors, the US Centers for Disease Control and Prevention has changed its Covid-19 testing guidelines to say some people without symptoms may not need to be tested, even if they've been in close contact with someone known to have the virus.
Previously, the CDC said viral testing was appropriate for people with recent or suspected exposure, even if they were asymptomatic.
Dr. Leana Wen, an emergency physician and public health professor at George Washington University who was previously Baltimore's health commissioner, said on CNN's New Day on Wednesday that the testing guideline changes make no sense.
"These are exactly the people who should be tested," Wen said, giving the example of a person exposed at work who wants a test so they can protect their family at home.
