Re-infection of SARS-CoV-2 is a rare entity. There have been only a few reports of SARS-CoV-2 re-infection reported from across the world. It is widely believed that genetic variants in the SARS-CoV-2 genome are responsible for re-infection. No data is yet available on host factors responsible for re-infection, though some evidence points to the key role of germinal centre development and re-infection, suggesting a potential subtle primary or secondary immunodeficiency.

If you know of a case of reinfection, please let us know. While non-clinicians could suggest a case, we would need a clinician to formally refer the case to us.
