Officials said the shorter time period is intended to encourage more people to quarantine. .
"Reducing the length of quarantine may encourage more people to do so, especially when they may not be able to work during quarantine time," CDC's COVID-19 Incident Manager, Dr."As we learn more about the virus, we continue to refine our guidance," Walke said, emphasizing that everyone should quarantine if they are exposed — or are concerned about exposure — to the coronavirus.He added that people should continue to monitor themselves for symptoms for 14 days after exposure — even if they end quarantine sooner. .
John Brooks, chief medical officer for the CDC, when quarantine is reduced to 10 days, the "residual risk" of someone exposing someone else after leaving quarantine is only about 1%.
"All of these point to the same thing — that a person leaving quarantine early could expose someone else.
"And when you have a 14-day quarantine period, that's such a long period of time that a lot of people aren't going to follow that anyway, and it makes it difficult to adhere to recommendations.
So putting in place a 10-day quarantine period, even a seven-day quarantine period, you're going to capture the vast majority of infections within that time frame.".
