I've tested positive for COVID-19 infection; how soon do I need to be tested again? Once you've tested positive for the virus, you do not need to be tested again for 90 days from symptom onset, if you became ill, or from the date of your positive test, if you remained asymptomatic.

When should I end isolation after a positive COVID-19 test?

Isolation and precautions can be discontinued 10 days after the first positive viral test.

Can someone test negative and later test positive on a viral test for COVID-19?

Yes, it is possible. You may test negative if the sample was collected early in your infection and test positive later during this illness. You could also be exposed to COVID-19 after the test and get infected then. Even if you test negative, you still should take steps to protect yourself and others. See Testing for Current Infection for more information.

How long can you spread COVID-19 after testing positive?

People with COVID-19 can spread the virus to other people for 10 days after they develop symptoms, or 10 days from the date of their positive test if they do not have symptoms. The person with COVID-19 and all members of the household should wear a well-fitted mask and consistently, inside the home.

How long after being infected can symptoms of COVID-19 still appear?

In rare cases, symptoms can show up after 14 days. Researchers think this happens with about 1 out of every 100 people. Some people may have the coronavirus and never show symptoms. Others may not know that they have it because their symptoms are very mild.

When are people who had COVID-19 no longer contagious?

You can be around others after: 10 days since symptoms first appeared and. 24 hours with no fever without the use of fever-reducing medications and. Other symptoms of COVID-19 are improving*

*Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation​

How long do COVID-19 patients continue to shed the virus?

The duration of viral shedding varies significantly and may depend on severity. Among 137 survivors of COVID-19, viral shedding based on testing of oropharyngeal samples ranged from 8-37 days, with a median of 20 days.

When can you be around others after being severely ill with COVID-19?

People who are severely ill with COVID-19 might need to stay home longer than 10 days and up to 20 days after symptoms first appeared.

Are recovered persons with persistent positive test of COVID-19 infectious to others?

Persons who have tested persistently or recurrently positive for SARS-CoV-2 RNA have, in some cases, had their signs and symptoms of COVID-19 improve. When viral isolation in tissue culture has been attempted in such persons in South Korea and the United States, live virus has not been isolated. There is no evidence to date that clinically recovered persons with persistent or recurrent detection of viral RNA have transmitted SARS-CoV-2 to others.

Despite these observations, it’s not possible to conclude that all persons with persistent or recurrent detection of SARS-CoV-2 RNA are no longer infectious. There is no firm evidence that the antibodies that develop in response to SARS-CoV-2 infection are protective. If these antibodies are protective, it’s not known what antibody levels are needed to protect against reinfection.

What should a person who recovered from COVID-19 do when they are exposed to it again, according to the CDC?

The following applies to a person who has clinically recovered from SARS-CoV-2 infection that was confirmed with a viral diagnostic test and then, within 3 months since the date of symptom onset of the previous illness episode (or date of positive viral diagnostic test if the person never experienced symptoms), is identified as a contact of a new case. If the person remains asymptomatic since the new exposure, then they do not need to be retested for SARS-CoV-2 and do not need to be quarantined. However, if the person experiences new symptoms consistent with COVID-19 and an evaluation fails to identify a diagnosis other than SARS-CoV-2 infection (e.g., influenza), then repeat viral diagnostic testing may be warranted, in consultation with an infectious disease specialist and public health authorities for isolation guidance.

What are consequences of a false negative COVID-19 test?

Risks to a patient of a false negative test result include: delayed or lack of supportive treatment, lack of monitoring of infected individuals and their household or other close contacts for symptoms resulting in increased risk of spread of COVID-19 within the community, or other unintended adverse events.

What does a negative COVID-19 test result mean?

A negative test result for this test means that SARS- CoV-2 RNA was not present in the specimen or the RNA concentration was below the limit of detection. However, a negative result does not rule out COVID-19 and should not be used as the sole basis for treatment or patient management decisions.

Can you still have detectable SARS-CoV-2 RNA after recovering from COVID-19?

Some people who have recovered may have detectable SARS-CoV-2 RNA in upper respiratory specimens for up to 3 months after illness onset, albeit at concentrations considerably lower than during illness, in ranges where replication-competent virus has not been reliably recovered and infectiousness is unlikely.

How long should I stay in home isolation if I have COVID-19?

People who are severely ill with COVID-19 might need to stay home longer than 10 days and up to 20 days after symptoms first appeared. People with weakened immune systems may require testing to determine when they can be around others. Talk to your healthcare provider for more information.

Do I need to self-quarantine after recovering from COVID-19?

• People who have been diagnosed with COVID-19 within the last three months and recovered do not have to quarantine or get tested again as long as they do not develop new symptoms.

What to do if you test positive for COVID-19 on a home test?

If your COVID-19 test is positive, tell a healthcare provider about your positive result and stay in contact with them during your illness. To avoid spreading the virus to others, follow CDC's guidance for isolation.

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 the person who has clinically recovered from COVID-19 continue to wear a cloth face covering in public?

Yes. It is recommended that all persons, with a few exceptions, wear cloth face coverings in public.

Should fully vaccinated persons isolate themselves from others if they get infected with COVID-19?

Although the risk that fully vaccinated people could become infected with COVID-19 is low, any fully vaccinated person who experiences symptoms consistent with COVID-19 should isolate themselves from others, be clinically evaluated for COVID-19, including SARS-CoV-2 testing, if indicated.

When to end quarantine for COVID-19?

Your local public health authorities make the final decisions about how long quarantine should last, based on local conditions and needs. Follow the recommendations of your local public health department if you need to quarantine. Options they will consider include stopping quarantine

After day 10 without testing
After day 7 after receiving a negative test result (test must occur on day 5 or later)

How long can long Covid last?

The medical community has been aware that while most people recover from COVID-19 within a matter of weeks, some will experience lingering symptoms for 4 or more weeks after developing COVID-19. Until now, there has not been a formal definition for this condition.

What does a negative SARS-CoV-2 antibody test mean?

A negative result on a SARS-CoV-2 antibody test means antibodies to the virus were not detected in your sample. It could mean:
• You have not been infected with COVID-19 previously.
• You had COVID-19 in the past but you did not develop or have not yet developed detectable antibodies.

How are COVID-19 and SARS-CoV-2 related?

The novel coronavirus, or SARS-CoV-2, is a potentially deadly virus that can lead to COVID-19.

How long can COVID-19 antibodies be detected in blood samples?

Antibodies may be detected in your blood for several months or more after you recover from COVID-19.

Does a negative result rule out the possibility of COVID-19?

A negative result does not rule out COVID-19 and should not be used as the sole basis for treatment or patient management decisions. A negative result does not exclude the possibility of COVID-19.
