Abstract
The rapidly spreading Covid-19 pandemic resulted in more than 4.7 million cases diagnosed and 78,727 deaths on September 14, 2020. SARS-CoV-2 was first expected to induce a monophasic disease with at least transient immunity. Here we report a case series of five cases of RT-PCR proved reinfection of Covid-19 in health care workers. On returning to work they might experience a Covid-19 “recurrence” or “reactivation” with increased severity of symptoms after a median symptom-free interval requiring hospitalization which raises the question is the immunity short-lasting. Further studies are required to fully understand the effect of Covid-19 on the immunity of humans in the community. J Microbiol Infect Dis 2021; 11(2):105-107.
