CDC refuses to explain the changes, Brett Giroir at HHS, a Trump stooge who has already publicly downplayed the need for testing, says it's all cool.
Before changes were made Monday, the CDC website said testing was recommended “for all close contacts of persons with SARS-CoV-2 infection.”
The website now says someone who was in close contact (within 6 feet) of a person with COVID-19 for at least 15 minutes but doesn’t have symptoms does not “necessarily need a test.”
. . . .
The CDC estimates in its COVID-19 Pandemic Planning Scenarios that 40% of infections are asymptomatic and 50% of transmissions occur before symptoms appear. Experts worry that failing to test asymptomatic carriers could not only result in more infections but also hinder contact tracing efforts.
