Its probably a good idea, out of an abundance of caution, to still wear a maskfor 48 hours until they can take another test, she adds. One lesson is that prolonged positive results are common enough that people who leave isolation before Day 10 should continue to take precautions, such as wearing a well-fitting mask, experts said. Symptomatic people who test positive can re-enter the community after a period of isolation of at least 10 days from the onset of symptoms, accompanied by a negative molecular or antigenic test after at least 3 days without symptoms (not counting changes in smell and taste). While zealously doing additional tests may seem prudent, it doesnt stand to be that useful. "So reading the labels of those medicines you might get over the counter is also important.". 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.

Chan School of Public Health in the department of immunology and infectious diseases, tells TODAY.com. Here's what to know. 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.

Some severely immunocompromised persons with COVID-19 may remain infectious beyond 20 days after their symptoms began and require additional SARS-CoV-2 testing and consultation with infectious diseases specialists and infection control experts. A preprint study of close to 100 vaccinated college students at Boston University suggests that a majority were no longer infectious after five days. Keep in mind that the most common symptoms of COVID-19 may be somewhat different now than they were earlier in the pandemic. Those symptoms should go away on their own within two days, experts said.

In a study published in JAMA Network Open in October, researchers looked at repeated rapid testing results for 942 people during last winter's omicron BA.1 wave. 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. And many experts advise waiting until you test negative on an at-home test before venturing out.
