Coronavirus disease has caused seven million infections worldwide, of which, 3.1 million individuals have recovered. Though, most individuals develop antibodies, whether these antibodies result in clinical improvement/immunity from future infection is not known. It is also not known about durability of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). No human re-infection with SARS-CoV-2 has been confirmed to date, although a few case reports have mentioned patients who have tested positive again after recovery from the initial illness. Whether these cases represent a state of carrier or re-infection or reactivation, is not known. Nevertheless, the possibility of re-infection remains a matter of concern and yet another question about SARS-CoV-2 which is still unanswered.
