EVIDENCE FOR REINFECTION WITH SARS-COV-2: A CASE SERIES STUDY

Protective immunity conferred by COVID-19 (severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unknown and reinfection with SARS-CoV-2 is not studied well. There are few case reports for reinfection with COVID- 19 which put a question marks on long lasting immunity after COVID- 19 infection. We present five cases with reinfection with SARS-CoV-2.Their age range 25-37years-old, all are united Arab Emirates ( UAE) resident with no travel history for the previous year tested positive for SARS-CoV-2 during a community screen campaign.All tests were done by qualitative PCR test for SARS-CoV-2 RNA through Nasopharyngeal swabs obtained from the patients. The course of disease in the three patientsranging from mild symptoms to asymptomatic. They had multiple SARS-CoV-2 negative test result between April 2020 to October 2020 before reinfection.Thedurations between first and second infections ranging from three to six months.Hence, we suggested that individuals with the previous infection with SARS-CoV-2 dont have long3lasting immunity against reinfections and general precautions are advised for individuals with previous SARS-CoV-2 infections.
