Coronavirus Update: New COVID Quarantine Rules: What? Why?The CDC revised guidance for people who have had close contact for at least 15 minutes with someone recently diagnosed with COVID. First a bit of background. Since March, the CDC has recommended that everyone with close exposure quarantine themselves for 14 days to prevent the spread of the virus to others. As researchers have learned more about the infection, we now understand that for those who do not become sick by the 7th day after exposure, the likelihood of them transmitting the infection to others is still 11%. By the 10th day after exposure, the potential is down to 1.4%.
The CDC’s new guidance decreases the length of quarantine to 10 days after exposure as long as the person has not gotten sick. There is an alternative quarantine of 7 days if someone also has a negative COVID test 1-2 days before that and stays healthy through day 7. Having a negative PCR test, which usually takes 2-4 days to come back from the lab, reduces the risk of a person transmitting the virus from 1 in 9 down to 1 in 25. Rapid tests are not nearly as accurate in detecting infections prior to the onset of symptoms. As a result, a rapid test along with no symptoms by day 7, leaves a 1 in 12 to 1 in 18 chance that a person is still infectious to others. > Read More
