How long can you test positive for covid-19 after having it?

After the test result is positive, you may continue to test positive for some time. You may continue to test positive for antigens for a few weeks after the first positive result. You can continue to test positive for NAAT for up to 90 days. Day zero is the day the symptoms start.

The first day is the first full day after the onset of symptoms. If you don't have symptoms or the symptoms go away after five days, you can leave your house with a mask on. If you have a fever five days after testing positive or showing symptoms, continue to isolate it until the fever goes away. To calculate your five-day isolation period, day 0 is the first day of symptoms.

If you have a medical emergency and need to call 911, notify dispatch staff that you have or may have COVID-19.Finally, the use of a poor technique when taking samples from the nose or mouth can result in a too low amount of virus to give a positive test result. Second, a mild COVID-19 infection in a person who has been vaccinated and boosted can cause a viral level high enough to cause symptoms, but too low to give a positive result in a rapid test. In addition, a small number of people who have been treated with the oral antiviral drug Paxlovid tested negative for rapid antigens, with no symptoms, only to “recover” between seven and 14 days after their initial positive test. If you've had COVID-19 in the past 90 days, you should still be tested if you have symptoms, but use an antigen test instead of a PCR or other molecular test, because molecular tests can continue to detect the COVID-19 virus even after you feel better.

In most cases, people test positive for COVID-19 with an antigen or a rapid test for up to 10 days, Matt Binnicker, PhD and director of clinical virology at the Mayo Clinic, told Health. If you are exposed to a person who has COVID-19 or has symptoms but receives a negative test result, another test should be done within 48 hours. According to the Centers for Disease Control and Prevention (CDC), people who don't have symptoms can end isolation 5 days after a positive test, while those who do have symptoms can end up in isolation 5 days after a positive test, as long as their symptoms improve and they don't have a fever for 24 hours.

CDC also does not recommend repeating the test, presumably with a PCR test, within three months of a previous positive test. This is because it is also possible to test positive for COVID-19 for weeks or even months after the initial infection, despite having no symptoms. The Centers for Disease Control and Prevention (CDC) has created an online, mobile-friendly calculator that provides an easy-to-use way to help people follow their isolation and precautions for people with COVID-19 and to obtain personalized information to address their particular situation. Several studies have demonstrated a correlation between the time a person tests positive for a rapid test and the time when a live virus can be collected from a person, which is a common way to determine if a person is infectious.

As fall temperatures hit, cold and flu season begins to peak and vacation travel increases, people will no doubt have questions about testing for COVID-19.However, simply being up to date with your COVID-19 vaccines can replace the need to get a negative test result in some cases. .
