Some of those symptoms congestion, sore throat, cough, fever might be easily confused with other common illnesses, such as the flu, allergies, RSV or the common cold.

They found that more than half of them still tested positive on antigen tests after six days. "The FDA has now suggested that some of these home tests really require serial testing if you're testing negative to get the best, most accurate results," Volk explains. If they test positive, they should proceed as though they might be contagious, Dr. Gordon said. Thats a pretty good indication that theyre likely to be infectious, said Dr. Amy Barczak, an infectious disease expert at Massachusetts General Hospital, who found that 25 percent of people still had viable virus on Day Eight or beyond. If a patient has persistently positive nucleic acid amplification tests beyond 30 days, additional testing could include molecular studies (e.g., For the purposes of this guidance, moderate to severely immunocompromising conditions include, but might not be limited to, those defined in the interim clinical considerations for people with. But those with more moderate or severe cases, as well as those who are immunocompromised, may need to perform more tests to leave isolation based on advice from their medical team, the CDC says.

Included evidence for expanding recommendations to include children. CDCs COVID-19 Community Levels recommendations do not apply in healthcare settings, such as hospitals and nursing homes. Added information around the management of persons who may have prolonged viral shedding after recovery. For example, one study analyzing data from a testing site in San Francisco during the January omicron surge suggests that many people were still testing positive after five days. You might be able to begin slowly sort of reintegrating while still being mindful of your contact," Kissler said.

At-home antigen tests may return positive results for 10 days -- or even longer, up to 14 days, according to The New York Times. "That explains a lot of the variation across studies, but I think it's still pretty consistent as an overall finding that if you're antigen positive, then you're quite likely to be infectious," he says.

People who are infected but asymptomatic or people with mild COVID-19 should isolate through at least day 5 (day 0 is the day symptoms appeared or the date the specimen was collected for the positive test for people who are asymptomatic). Keep in mind that the most common symptoms of COVID-19 may be somewhat different now than they were earlier in the pandemic.
