Asked by: Alanis Leuschke I

If a previously infected person has recovered clinically but later develops symptoms suggestive of COVID-19 infection, they should be both quarantined and retested.

How long does immunity last after Covid infection?

Studies have suggested the human body retains a robust immune response to the coronavirus after infection. A study published in the journal Science early this year found that about 90 percent of patients studied showed lingering, stable immunity at least eight months after infection.

Can people who recover from COVID-19 be re-infected with SARS-CoV-2?

CDC is aware of recent reports indicating that persons who were previously diagnosed with COVID-19 can be re-infected. These reports can understandably cause concern. The immune response, including duration of immunity, to SARS-CoV-2 infection is not yet understood. Based on what we know from other viruses, including common human coronaviruses, some reinfections are expected. Ongoing COVID-19 studies will help establish the frequency and severity of reinfection and who might be at higher risk for reinfection. At this time, whether you have had COVID-19 or not, the best ways to prevent infection are to wear a mask in public places, stay at least 6 feet away from other people, frequently wash your hands with soap and water for at least 20 seconds, and avoid crowds and confined spaces.

Do people who have recovered from the coronavirus disease develop immunity?

While individuals who have recovered from SARS-CoV-2 infection might develop some protective immunity, the duration and extent of such immunity are not known.

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.

How does your immune system act after you recover from COVID-19?

After you recover from a virus, your immune system retains a memory of it. That means that if you get infected again, proteins and immune cells in your body can recognize and kill the virus, protecting you from the disease and reducing its severity.

How long do antibodies last in people who have mild COVID-19 cases?

A UCLA study shows that in people with mild cases of COVID-19, antibodies against SARS-CoV-2 — the virus that causes the disease — drop sharply over the first three months after infection, decreasing by roughly half every 36 days. If sustained at that rate, the antibodies would disappear within about a year.

A positive result means the test did detect antibodies to the virus that causes COVID-19, and it is possible that you had a recent or prior COVID-19 infection and you have developed an adaptive immune response to the virus.

At what point after infection with COVID-19 will there be enough antibodies to be detected in an antibody test?

After infection with the COVID-19 virus, it can take two to three weeks to develop enough antibodies to be detected in an antibody test, so it’s important that you’re not tested too soon.

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

Vaccines work by stimulating your immune system to produce antibodies, exactly like it would if you were exposed to the disease. After getting vaccinated, you develop immunity to that disease, without having to get the disease first.
