CDC covid testing guidance goes from haphazard to ass-backwards
==============
Earlier this week, the CDC revised its guidelines for covid testing.
For background, the CDC categorized people into “five populations” for which COVID-19 testing may be appropriate:
- Individuals with signs or symptoms consistent with COVID-19 (“aka “symptomatics”)
- Asymptomatic individuals with recent known or suspected exposure to COVID-19 (e.g. in close contact for more than 15 minutes with an infected person; living in a high COVID-19 transmission area; having attended a public or private gathering of more than 10 people (without widespread mask wearing or physical distancing)
- Asymptomatic individuals without known or suspected exposure in special settings (e.g. frontline medical personnel and nursing home caregivers)
- Individuals being tested to determine resolution of infection (e.g. to establish a safe return to work after a prior positive test)
- Individuals being tested for purposes of public health surveillance (e.g. to determine the prevalence of COVID-19 in a targeted locale such as an apparent hot spot city or campus)
The CDC previously recommended testing for people in categories in the first 3 categories.
Here’s the big change to the CDC guidance … and why it’s wacky.
