"What folks really need to understand is that right now we are in flu season and RSV season and we still have COVID hanging around," Dr. Emily Volk, president of the College of American Pathologists, tells TODAY.com. "So reading the labels of those medicines you might get over the counter is also important.". Here's what to know. But this is asking a lot of folks, she adds. According to a new analysis of people who sought repeat testing at a California site during the Omicron wave, an estimated 71 percent were antigen-positive four days after their symptoms appeared or after they first tested positive for the virus. Chan School of Public Health, said it's not unreasonable to gradually leave isolation even if youre still testing positive using a rapid test. Given the uncertainty, some experts have advised that test results at the end of an infection be viewed as just one potentially useful piece of information considered in concert with other factors, including a patients symptoms and immune status. 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. Consider consultation with infection control experts. 3. ), Those studies were done pre-omicron. Isolation should continue for at least 10 days after symptom onset (day 0 is the day symptoms appeared, and day 1 is the next full day thereafter). Regardless of when you end isolation, anyone who tests positive for COVID-19 should take certain precautions for 10 full days, the CDC says including masking around or after 10 days if they were continuing to test positive. You can continue to follow that advice if you wish, and you have tests available. The NHS says most people with Covid-19 or will feel better within a few weeks.

But there are a lot of factors that can affect how long someone may test positive. And a third study, of 260 vaccinated health care workers in Chicago, found that overall, 43% were testing positive on rapid antigen tests five to 10 days after infection with omicron even though they felt well enough to return to work. You can also take a test before attending an indoor gathering, especially if you know you won't be wearing a mask. Ideally, if you have access to enough tests, you wouldnt stop masking until you get two consecutive negative rapid test results taken 48 hours apart, Volk says. "The way that we've started to frame it, and I think many others have, is that if you're positive, you particularly need to take this very seriously.". But if you feel fine, it can be frustrating to wait, especially if you're in the subset of those who test positive past 10 days. If you get a positive test on a home rapid antigen test, you can trust the result, Volk says, provided you performed the test correctly. Whereas with other individuals actually, with a family member recently, I had to be like, Dont hurt yourself, because they were really, really getting in there.. It just causes trouble.. And research done by the CDC shows about half of people were still testing positive on the antigen test between five and nine days after symptom onset or diagnosis.

Some people with severe illness (e.g., requiring hospitalization, intensive care, or ventilation support) may remain infectious beyond 10 days. 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. In general, people with weaker immune systems are likely to take longer to fight off the virus, scientists said, although even young, healthy and fully vaccinated people may be positive for extended periods. The two experts I checked with, Coffey, as well as Dr. Robin Colgrove, an assistant professor and infectious disease specialist at Harvard Medical School, agreed that after 10 days of isolation, you probably dont need to keep testing at all if youre not immunocompromised.

They Went Extremely Hardcore for Elon Musk and He Axed Them Anyway, One of the Worlds Most Dangerous Places Is About to Drill One of Its Most Important Mines. But early data suggests that a maximum infection period of 10 days holds for omicron, too: a small preprint from Japans National Institute of Infectious Diseases found that they were still unable to isolate infectious virus from vaccinated people after 10 days. So by the time you reach day eight, nine or 10, you still have the chance to spread to other people, but its probably not as much as you did early in the course of your infection, Kissler says. The incubation period for COVID is said to be two to 14 days, with an individual considered infectious starting two days before they develop symptoms or two days before the date of their positive test, if they do not have symptoms. Isolation can be discontinued at least 5 days. Added information on recent reports in adults of reinfection with SARS-CoV-2 variant viruses. Even if it is an imperfect tool, not everyone is down on using a rapid antigen test. 4. 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.

In a study published in Clinical Infectious Diseases in June, researchers found that 17% of participants had active viral cultures beyond day five. Coffey, an assistant professor of epidemiology and public health and medicine at the University of Maryland School of Medicine, a positive test could be detecting viral antigens that have already been bound by antibodies, which would make them nontransmissible. The most frequent symptoms these days include sore throat, runny nose, congestion and sneezing. Landon says it's extra information that can give you a sense of how to proceed, especially if people are banking on the CDC guidance to determine whether to end isolation. Even with a rapid test, which detects molecules on the virus's surface as opposed to the virus's genetic material, it's not unheard of for people to test positive up to 14 days, especially for those who are unvaccinated, Kissler says. Many of the at-home tests the government sends out, as well as those you may have purchased, are good to use for six months or more. Instead, you should follow your symptoms and count the days and continue to mask up around others. In some cases, these people may still be shedding infectious virus, but in others, the tests may be picking up viral debris from a waning infection, experts say, making it difficult to know how to interpret the results. The safest strategy is to continue to isolate until you're no longer testing positive, the experts stress. Even with the arrival of new subvariants, the basic ground rules haven't changed since omicron first came onto the scene: the Centers for Disease Control and Prevention says someone can stop isolating after five days if they're fever-free for 24 hours and are starting to get better as long as they keep wearing a mask around others for another five days. If you must interact with others before testing negative, make sure to wear a high-quality mask, maintain distance from other people when you can, and avoid spending time in enclosed spaces around other people.

The criteria for serial testing to end isolation are: Results are negative from at least two consecutive respiratory specimens collected 24 hours apart (total of two negative specimens) tested using an antigen test or nucleic acid amplification test. You can leave isolation after five days if you never developed symptoms or if you had symptoms that are improving (including at least 24 hours without a fever and without the use of fever-reducing medications), the CDC says.
