Background The rapid spread of the COVID-19 pandemic which took a place in Wuhan, China and diffused globally required the international public health to take a coordinated international response. As other coronaviruses were described, SARS-CoV-2 was thought to be an immunizing, monophasic disease. Herein, we reported first two COVID-19 cases registered in Saudi Arabia whose nasopharyngeal swabs turned positive for SARS-CoV-2 ribonucleic acid (RNA) after recovery.Case presentation First patient who is symptomatic with recurrence of positive SARS-CoV-2 RNA occurred 115 days after the first symptomatic infection and did not develop protective immune response. Second patient who is asymptomatic during the recurrence of positive SARS-CoV-2 RNA occurred 60 days after the first symptomatic infection in an apparently immunocompetent patient.Conclusion These findings highlight the recurrence of positive SARS-CoV-2 after recovery even if SARS-CoV-2 antibodies were developed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
