In a mindboggling and dangerous move, the Centers for Disease Control and Prevention this week quietly reversed its recommendation on COVID-19 testing for those exposed to the virus. Now, the CDC says that exposed but symptomless people do not need to be tested. From a report: The change immediately alarmed and outraged public health and infectious disease experts. It is well established that SARS-CoV-2 — the pandemic coronavirus that causes the disease COVID-19 — can cause completely asymptomatic infections in some and spread from other infected people before they develop symptoms (so-called “pre-symptomatic transmission”). In fact, some modeling studies have suggested that pre-symptomatic transmission may account for nearly half, or even more, of SARS-CoV-2 spread.

That information previously spurred the CDC to recommend testing for anyone that was known to have — or even suspected to have — close contact with an infected person (that is, be within six feet for 15 or more minutes). “Testing is recommended for all close contacts of persons with SARS-CoV-2 infection,” the agency said on its website as recently as August 22. “Because of the potential for asymptomatic and pre-symptomatic transmission, it is important that contacts of individuals with SARS-CoV-2 infection be quickly identified and tested.”
