CDC Flip-Flops on Coronavirus Testing Guidelines
b'New CDC guidelines for asymptomatic coronavirus testing caused an uproar this week. The advice was that people who\\u2019ve been exposed to the coronavirus but don\\u2019t have symptoms shouldn\\u2019t get tested. But then, in an unusual clarification, the CDC walked that back. Meanwhile, the FDA gave \\u201cemergency use authorization\\u201d to a rapid antigen test that costs only $5. Also this week, Governor Gavin Newsom signed a deal with a diagnostics lab to more than double test processing capacity in California. We\\u2019ll explain what these developments mean and which could help open schools and bring our economy back to life.'
