Anju Goel, MD, MPH, is a board-certified physician who specializes in public health, communicable disease, diabetes, and health policy. After being infected with COVID, there is curiosity about how often people should test themselves, when they should test, and whether they should continue to retest after having the illness.
Currently, the CDC guidelines indicate that if a person tests positive for COVID—regardless of vaccination status —they need to isolate at home for at least five days and take precautions for at least 10 days. This means that after five days, a person who does not have symptoms can end isolation if they can still wear a well-fitted mask around other people for an additional five days. People with mild symptoms should isolate for five days from symptom onset and ensure that their symptoms are improving and they are fever -free for 24 hours before ending isolation.
If symptoms have improved at day five, then they should continue wearing a well-fitted mask around other people for another five days. But, a person does not need to test, and the test result does not change whether a person still needs to wear a well-fitted mask for an additional five days. The CDC recommends that you only test if you have been fever-free for 24 hours without the use of fever-reducing medication and your other symptoms have improved.
If the test result is negative, the person can end isolation after day five and wear a well-fitted mask around others until day If the test result is positive, the person should continue to isolate until day After that time, no further testing is recommended, even if a person tested positive on day five.
These guidelines do not apply to moderately or severely ill people with COVID or people with weakened immune systems. Immunocompromised people should always isolate for at least 10 days, and up to 20 days for people who were severely sick with COVID If a person does not have access to repeat COVID testing after five days in isolation, or does not want to retest, the CDC recommends that people take precautions until day 10 by continuing to wear a well-fitted mask around others at home and in public.
People with mild to moderate symptoms often obtain COVID testing on their own and care for themselves at home. With the rise in cases, testing options are becoming harder to find. There are several at-home testing kits available, but they're scarce. The government has launched a program to help ease the testing hurdle by providing free at-home rapid COVID testing kits , but only four per household are allowed. People might obtain repeat COVID testing because they are under the impression that another positive COVID test result—even if symptoms are improving—means that they are still contagious.
These people may feel a duty to limit the spread of the disease further. However, many people can continue to test positive for the virus even though they are not symptomatic or contagious, sometimes for weeks or even months. For PCR tests, evidence shows that in most people, viral particles can be detected as early as six days before symptom onset and up until two weeks later.
However, although viral RNA can continue to be detected, scientists have not been able to grow live virus from collected specimens nine days after symptom onset. This suggests that even though a person can continue to test positive, they are no longer contagious eight days after symptom onset. These tests work by creating copies of viral genetic material in respiratory samples.
The tests can take a single copy of viral RNA and amplify it to show a positive result. Essentially, these tests are very good at detecting small amounts of viral material.
However, these viral fragments do not indicate a live virus. Their existence does not mean that the viral fragments can lead to symptoms or be passed to others.
These viral fragments can be detected for up to three months. The question to retest becomes more confusing when we add the element of repeat infection. People who have recovered from COVID develop protective antibodies that help prevent the virus from replicating and infecting new cells. However, scientists do not fully understand the effectiveness of this antibody protection or how long it lasts. Some research has suggested that neutralizing antibodies are present for at least six months.
Therefore, the risk of reinfection is low but not impossible, and reinfection is more likely in unvaccinated people. This concept also applies to people who are fully vaccinated, as breakthrough infections can occur in fully vaccinated people. Even if you have recovered from COVID or are fully vaccinated, it's still important to wear a mask indoors in a public setting and in close contact areas. During these three months, a positive test result could be associated with the previous infection rather than a new infection.
However, this recommendation differs if a person experiences symptoms consistent with COVID within the three months. In that case, repeat testing is recommended. If the test is positive, patients should undergo a repeat five-day isolation period, according to recommended guidelines. The CDC guides workplaces on implementing these testing strategies in non-healthcare settings.
According to the Americans with Disabilities Act ADA , employers who implement mandatory COVID testing of employees must ensure that the testing is job-related and consistent with a business necessity. The purpose of the program should be to identify current infections. Based on the evidence of continued positive results for months after illness, the CDC recommends a time-based and symptom-based strategy for determining when a person can return to work.
This strategy means that people should follow the CDC guidelines for five days of isolation and should not return to work unless their symptoms improve or resolve.
Public health organizations stress that this requirement could be burdensome, since healthcare professionals may be too busy to provide fitness for duty documentation. However, some employers require it anyway. Employers who have implemented regular COVID screening will likely require repeat testing when employees return to work. However, the ADA requires that employers follow current CDC guidelines regarding repeat testing and returning to work.
This condition occurs in people:. Research is still ongoing into understanding this constellation of symptoms. However, this initial risk analysis was performed in a small group of people, and scientists continue to analyze the risks. Over the last few months, infections have risen, prompting people to seek COVID testing and repeat testing to ensure they have recovered. However, the CDC does not recommend repeat COVID testing for people who have recovered from the illness, especially since many can continue to test positive for months and not be contagious.
The CDC only says that people with mild disease can repeat test to end isolation early at day five. However, people still need to wear a well-fitted mask until day Additionally, the CDC does not recommend repeat testing for returning to work. Instead, workplaces should follow the CDC guidelines and use a time-based and symptom-based strategy for returning to work.
If you've been infected and your symptoms have improved after five days of isolation, you do not need repeat COVID testing unless you become symptomatic again. You can rest assured that you are no longer contagious after 10 days of isolation. The best way to help your community is to save the tests for those that need them, isolate yourself for five days, and wear a well-fitted mask until day Sign up for our Health Tip of the Day newsletter, and receive daily tips that will help you live your healthiest life.
