Can you still test positive after recovering from COVID-19?

According to the Centers for Disease Control and Prevention, some people who contract COVID-19 can have detectable virus for up to three months, but that doesn't mean they are contagious. When it comes to testing, however, the PCR tests are more likely to continue picking up the virus following infection.

How long do most people continue to test positive for COVID-19?

According to the New York Times, the omicron variant of the coronavirus moves quickly, with viral levels typically peaking less than five days after the virus is first detectable. However, some people will continue to test positive for the virus even up to 14 days later.

How long could the COVID-19 virus linger in your body?

But for most infected people, virus levels in the body peak between three and six days after the original infection, and the immune system clears the pathogen within 10 days. The virus shed after this period is generally not infectious.

Can a person test negative and later test positive for COVID-19?


It is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID- 19. This means that you could possibly still have COVID- 19 even though the test is negative. The amount of antigen in a sample may decrease the longer you have symptoms of infection.

COVID-19: When are you no longer contagious after testing positive or experiencing symptoms?



Why can I test negative for COVID-19 even if I have symptoms?

Simply put: Depending on when you take a test, if you have COVID symptoms and receive negative results from an at-home, rapid test, the level of virus in your body could be too low to be detected by the test, at least at first.

What should I do if I still have symptoms after a negative COVID-19 test result?

If you use an at-home test that comes back negative, and you do have symptoms that persist or get worse, it's a good idea to get a lab-based PCR test for COVID-19 and influenza. You also should stay home and isolate until you get the PCR test results back. The antigen test may have missed an early infection.

How does the human body shed COVID-19?


Viruses make copies of themselves in human cells and then spread to other people. This is the process of viral shedding. People who are sick with COVID-19 shed the virus from their noses and mouths. While we can't stop viral shedding, we can stop those viruses from infecting other people.

Can patients who have recovered from COVID-19 continue to have detectable SARS-CoV-2 RNA in upper respiratory specimens?

• Patients who have recovered from COVID-19 can continue to have detectable SARS-CoV-2 RNA in upper respiratory specimens for up to 3 months after illness onset in concentrations considerably lower than during illness; however, replication-competent virus has not been reliably recovered and infectiousness is unlikely.

Should I isolate and get tested if I have recovered from COVID-19 but I have symptoms again?

If a previously infected person experiences new symptoms consistent with COVID-19 3 months or more after the date of the previous illness onset (or date of last positive viral diagnostic test [RT-PCR or antigen test] if the person never experienced symptoms), the person should undergo repeat viral diagnostic testing. However, serologic testing should not be used to establish the presence or absence of SARS-COV-2 infection or reinfection. These people who have a positive test result should be considered infectious and remain isolated until they again meet criteria for discontinuation of isolation or of transmission-based precautions. Contact tracing during the person’s second episode of symptoms is warranted.

Are you still contagious 10 days after the first day of COVID-19 symptoms?

So, there is potential for people to be infectious beyond their seven-day isolation if they are still symptomatic. After ten days, most people are not infectious. Multiple studies have shown there is very little, if any, transmission after day ten, regardless of the variant.

What is the incubation period of the COVID-19 variant?

Omicron is now the most dominant strain of coronavirus in the U.S., and its incubation period may be shorter than those of previous variants. Research is just beginning. But some scientists who've studied Omicron and doctors who've treated patients with it suggest the right number might be around 3 days.

Can a COVID-19 RT-PCR test be falsely negative?

Can you have COVID-19 and still test negative for antibody test?

A negative test means that you have no COVID-19 antibodies, so you probably were not infected with the COVID-19 virus in the past. Because it takes time for antibodies to develop, false-negative test results can happen if the blood sample is collected too soon after your infection started.

Can you get a false negative COVID-19 antigen test?


The antigen level in specimens collected either before symptom onset, or late in the course of infection, may be below the tests' limit of detection, resulting in a false negative antigen test result, while a more sensitive test, such as most NAATs, may return a positive result.
