Reinfection of COVID-19 in Pakistan: A First Case Report

Since its spread across the world, coronavirus disease 2019 (COVID-19) has posed a severe public health threat, and many unanswered questions about COVID-19 remain. Antibodies have been detected a few days after the onset of infection, and in some patients, these antibodies wane quickly. To date, it is unknown whether all infected patients induce an adequate protective immune response or how long this effect remains. Here, a first case report of COVID-19 reinfection in Pakistan is reported within two months of complete recovery from the first severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection confirmed with two sequential negative nasopharyngeal swabs.
