Is the antigen test positive after recovery?
So if the person being tested recently had COVID-19 and has completed their isolation period,It is possible for that person to receive a negative antigen test result and a positive NAAT endorsement, potentially indicating continued detection of SARS-CoV-2 after recovery from COVID-19.
You can still test positive on antigen testsa few weeksafter your first positive. You can continue to test positive for NAATs for up to 90 days.
It is common to continue to test positive after recovering from a COVID-19 infection. Some people still test positive for a PCR test forweeks or monthsafter their initial infection. This is because the PCR test detects remnants of the virus that are no longer alive and unable to cause infection.
Some severely immunocompromised people with COVID-19 can remain contagious for more than 20 days after their symptoms beginand require additional SARS-CoV-2 testing and consultations with infectious disease specialists and infection control experts.
If retesting is performed at all in asymptomatic individuals within 3 months of recovery from COVID 19, the test performed should be a rapid antigen test.
People are most contagious with COVID-19 during the first 5 days of their illness. Many people have no symptoms for the first 2 to 3 days of their illness. This is why COVID-19 outbreaks are so difficult to contain.On average, people are contagious for 5 to 10 days.
If you have a positive COVID-19 test result, you should follow the advice below:Stay home and avoid contact with other people for five days after the day of the test or from the day symptoms started (whichever came first).
If your LFD test result is positive on day 10 and your work at UHNM is patient-centric, thenThey should continue to perform daily LFD testing and not return to clinical tasks until a single negative LFD test result is obtained prior to Day 15.

We know that people are usually most contagious early in the course of their infection. At Omicron, most transmission occurs during theone to two days before the onset of symptoms and two to three days after.
Are you still contagious after 7 days?
If you are severely immunocompromised, you are more likely to be contagious for more than 7 days and potentially still be able to spread the virus. Follow these measures up to day 14 after your positive test result to further reduce the remaining risk of spreading the virus.
What to do if you test positive for COVID-19. If you have COVID-19,You can pass the virus on to other people for up to 10 days after you started getting infected.
Overall performance of at-home COVID-19 antigen testing
However, it is widely expected that at-home COVID-19 antigen testing will detect the SARS-CoV-2 virus at least 80% of the time someone is infected.If you take a COVID-19 antigen test at home and get a positive result, the results are usually accurate.
When do you stop being contagious if you have COVID-19? It depends on.If you have a mild illness and your symptoms are getting better, you are probably not contagious after 10 days. If you have a serious illness or a weakened immune system, you can be contagious for up to 3 weeks.
A positive test result means proteins from the virus that causes COVID-19 were found in your nasal swab sample. It is likely that you will need to self-isolate at home to prevent the spread of COVID-19. A positive result does not rule out co-infection with other pathogens.
Individuals with severe COVID-19 may remain contagious for more than 10 days and may need to extend isolation up to 20 days.Those who are moderately or severely immunocompromised should isolate themselves until at least day 20.
