These two coronavirus variants, called BQ.1 and BQ.1.1, are both subvariants of omicron, the strain that caused last winter's massive post-holiday surge. And some had positive viral cultures for as long as 12 days after the onset of their symptoms, suggesting they could still be contagious even past the 10-day mark. That's especially true if you're fully vaccinated, any symptoms you developed have resolved, and you continue to take other precautions (especially masking) until you get a negative result.

Rapid antigen tests have become useful tools for flagging people carrying high levels of the virus, but they are not perfect predictors of infectiousness. Anyone can read what you share. Some people may not be infectious at the end of their course even if still antigen-positive, whereas others may be infectious even if antigen-negative, said Dr. Yonatan Grad, an immunologist and infectious disease expert at the Harvard T.H. Considering that different tests may perform differently, and then you have all these variants, youre changing the variables of the equation over and over again, says Paniz-Mondolfi, who also leads the Saliva COVID Test Lab at Mount Sinai.

If someone you live with tests positive, you should self-isolate for 10 days from the day of the test or the day they start experiencing symptoms, whichever is first. Unlike PCR tests, which search for genetic material from the virus, rapid antigen tests work by looking for the proteins that are packed inside the virus. A preprint study of close to 100 vaccinated college students at Boston University suggests that a majority were no longer infectious after five days. The most frequently reported COVID-19 symptoms now include sore throat, sneezing, congestion, runny nose, cough, muscle aches, hoarse voice and an altered sense of smell, according to a Dec. 13 report from the ZOE Health Study. After 10 days, it's likely that "you're good to go," Paniz-Mondolfi agrees, and he says you're "even better to go" if you keep practicing those precautionary measures especially wearing a mask until you get a negative test. After undergoing five days of isolation and an additional five days of strict mask wearing, some people are still testing positive for COVID-19, even though the recommended isolation period has ended. Those without noticeable symptoms were less likely to test positive at both points.

Theyre probably less contagious than they were in the first few days, she added. So: While a positive result after 10 days could, in theory, mean that the virus is still replicating in your body, according to Coffey, its by no means firm evidence that it is. The safest strategy is to continue to isolate until you're no longer testing positive, the experts stress.

NHS guidance recommends people isolate for 10 days if they test positive for coronavirus.
