Sumario:During an ongoing pandemic of severe acute respiratory syndrome coronavirus 2, main question which has arisen in everyone's mind is about the immune response that may protect from reinfection. Coronaviruses are known for short-term immunity. Their ability of mutations enables them to escape host immunity, thus increasing chances of reinfection. Here we report two cases of reinfection among health care workers who presented with symptoms of COVID-19 disease, after 3 months of first infectious course. Such documentations are necessary for epidemiological purposes and also to monitor response of virus on re-exposure.
