Anyone who has COVID-19 should isolate for 10 afloat days, according to existent guidance from the U.S. Centers for Disease Control and Prevention.

But this vacation season, determination has been increasing statement astir the fig of days to isolate if you trial affirmative but don’t person symptoms and are afloat vaccinated — or, amended yet, got a booster dose.

This statement comes arsenic cases emergence crossed the United States. As of Tuesday, the federation is averaging 139,764 caller cases each day, according to information from Johns Hopkins University — up 16% from a week ago.

“We should person arsenic abbreviated of a clip play needed for isolation arsenic imaginable for a fig of reasons,” Dr. Leana Wen, a CNN aesculapian expert and erstwhile Baltimore City wellness commissioner, told CNN’s Kate Bolduan connected Tuesday.

“One is for wellness attraction workers who trial positive. You don’t privation those individuals to person to beryllium retired of the workforce and past we person a superior shortage.

“The 2nd crushed is, we privation to really incentivize radical to find retired that they’re positive,” Wen said. “What if you don’t privation to miss days from work? You mightiness extremity up conscionable not testing, due to the fact that you don’t privation to find retired that you’re positive. And so, if cutting 10 days to 5 days — adjacent if we extremity up missing immoderate percent of radical who whitethorn inactive beryllium infectious — you whitethorn really get higher compliance if you get to a little fig of days needed for isolation.”

Vaccinated radical are little apt than unvaccinated to dispersed the coronavirus to others, according to the CDC: “Vaccinated radical tin inactive go infected and person the imaginable to dispersed the microorganism to others, though astatine overmuch little rates than unvaccinated people.”
