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 doesnt mean they are contagious.
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.
While there are no current mechanisms that require reporting of self-test results to public health authorities, CDC strongly encourages everyone who uses a self-test to report any positive results to their healthcare provider.
"Any pink/purple line visible here indicates a positive result," the FDA states. Still, experts say "if you or the telehealth proctor disagree on the presence of a faint line and/or the presence of a line is uncertain, additional confirmatory testing should be conducted."
A Boston University study revealed that just 17% of people were likely still contagious six days after their first positive tests. If youre still testing positive outside the 10-day window, it may have to do with what type of test youre using.
"Youve gotta stay home for five days because typically those first five days are when you are the most contagious," Chicago Department of Public Health Commissioner Dr. Allison Arwady said. "But in those days six to 10, some people still can be spreading virus."
If youre still testing positive outside the 10-day window, it may have to do with what type of test youre using. Dr. Allison Arwady, commissioner of the Chicago Department of Public Health, previously said PCR tests are more likely to continue picking up the virus following infection.
Stay home, except to get needed medical care. Stay home from work and school, and avoid other public places including the store. If you must go out, avoid public transportation or ridesharing/taxis. Stay far away (6 feet or more) from other people. Wear a mask at all times and wash or sanitize your hands often.

If you need to be around other people or animals in or outside of the home, wear a mask.Tell your close contacts that they may have been exposed to COVID-19. An infected person can spread COVID-19 starting 48 hours (or 2 days) before the person has any symptoms or tests positive. By letting your close contacts know they may have been exposed to COVID-19, you are helping to protect everyone.• Additional guidance is available for those living in close quarters and shared housing.• See COVID-19 and Animals if you have questions about pets.• If you are diagnosed with COVID-19, someone from the health department may call you. Answer the call to slow the spread.
The tests seem to be most accurate when viral loads are high, so experts think a negative could mean youre less likely to spread the virus.
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.
Positive results are usually highly accurate but negative results may need to be confirmed with a PCR test. Rapid tests are most effective one to five days after symptoms start.
