Scientists are trying to figure out if getting the disease once can protect you from reinfection - something that normally happens in most infectious diseases. Widespread antibody tests are being done in some areas to look for the presence of COVID specific antibodies in the population to check for the possibility of secondary infection and to trace the spread of the disease. About 80 percent of the cases of COVID are mild or asymptomatic so it is likely that a lot of people may have gotten the disease and have recovered without even realizing.

A group of researchers at the Karolinska Institutet and Karolinska University Hospital, Sweden have found that   immunity to COVID may be more widespread in the general population than an antibody test can tell. And hence there might be a need to change our tactics for tracing immunity responses against the disease. The study is still in the pre-print phase and is not yet peer-reviewed. Normally, when a person gets a disease, their immune system makes antibodies to fight the pathogen.

After recovering, some of these antibodies stay in our body to recognise and quickly eliminate the same pathogen, in case we get exposed to it a second time. Antibodies are specific to a pathogen. So an antibody against one pathogen may not protect you against another.

Though some animal studies show that the immune system makes antibodies against the SARS-CoV2 virus which can protect from reinfection, there have been previous cases of a second infection in recovered patients. Also, it has been found that those who get mild disease do not even have detectable levels of antibodies.

The recovered person, too, can develop other symptoms, including insomnia and neurological problems, said Angela Rasmussen, a virologist at Columbia University. Rasmussen said. Coronaviruses are on the whole poorly understood, she said. Before the SARS epidemic, coronaviruses were not known to cause serious illnesses. Some scientists have said that people infected with the new coronavirus produce antibodies that will protect them in the future.

And a single-patient report suggests that the immunity may last at least seven days. But this finding is neither surprising nor reassuring, said Dr. Stanley Perlman, a coronavirus expert at the University of Iowa.

Perlman said, and only one that he has heard of in a patient recovering from MERS. How long immunity lasts will also be a key question to resolve when designing a vaccine for the new coronavirus, particularly if the virus becomes a seasonal threat like influenza.

Similar cases have come to light in India too.
