Anyone who has COVID-19 should isolate for 10 full days, according to current guidance from the US Centers for Disease Control and Prevention.
But this holiday season, there has been growing debate around the number of days to isolate if you test positive for COVID-19 but don't have symptoms and are fully vaccinated -- or, better yet, got a booster dose.
This debate comes as COVID-19 cases rise across the United States. As of Tuesday, the nation is averaging 139,764 new cases each day, according to data from Johns Hopkins University -- up 16% from a week ago.
"We should have as short of a time period needed for isolation as possible for a number of reasons," Dr. Leana Wen, a CNN medical analyst and former Baltimore City health commissioner, told CNN's Kate Bolduan on Tuesday.

Omicron variant symptoms: What to know even if you are vaccinated
The omicron variant is leading to a significant surge in COVID-19 cases in the United States and across Europe.

In those countries, cases of the variant are doubling every 1.5 to 3 days. Here's what to know.
