Can People Without Symptoms Get Tested for Covid? Who Knows

Science article by By Megan Molteni online at Wired.com, August 28, 2020.

The CDC just quietly revised guidelines on who should get tested. Last month CDC directer Redfield said “anyone who thinks they may be infected—independent of symptoms—should get a test.” The new guidance says those who have been exposed but have no symptoms do not necessarily need a test. This makes zero epidemiologic sense since identifying asymptomatic sources of transmission is a top priority. Where did this new guidance come from? This story reports on the firestorm of criticism that has been unleashed by this seemingly minor change. Tom Frieden, former CDC director under President Obama, called the change “unexplained, inexplicable, probably indefensible.” Did the White House insist on the shift to dampen testing and improve the numbers for political reasons? Read this and decide for yourself.


Today’s bite-sized, handpicked selection of important news, information or science for all who want to know where this epidemic is going and what we should do.
