Coronavirus disease 2019 (COVID-19) is a pandemic disease spread globally .It is  caused by the SARS-COV-2 virus surface spike protein binding to the human angiotensin-converting enzyme 2 (ACE2) receptor, that is expressed in the lung (type 2 alveolar cells), heart, intestinal epithelium, vascular endothelium, and kidneys, providing a mechanism for multi-organ dysfunction. The median incubation period time is 4 to 5 days and 97.5% of patients will exert symptoms within 11.5 days1.Reinfection by COVID 19hs been documented in various parts of the world and is quite alarming. I am reporting a probable case of reinfection by SARS CoV 2 at Government Medical College, Kannur, Kerala.
