Little is known about the pathophysiology and immunology of Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2). It is not yet clear whether SARS-CoV-2 infection produces long-term immune protection, or a short-lived immunity that would fade with the passage of time . We report a first case of SARS-CoV-2 reinfection in second wave from Pakistan . A 41-year-old male, health care worker developed flu-like illness, tested positive on 6th June 2020 and became PCR negative on 19th June 2020 with reactive antibodies . After 4 months and 13 days of negative PCR, he developed symptoms again and tested positive for SARS-CoV-2 with non-reactive antibodies.
