Abstract
Background: The ongoing coronavirus disease 2019 (COVID-19) global pandemic caused by the SARS-CoV-2 virus remains a major threat to public health. At present, it is recommended that patients with known or suspected COVID-19 undergo quarantine or medical observation for 14 days. However, recurrent SARS-CoV-2 RNA positivity and prolonged viral shedding have been documented in convalescent COVID-19 patients, complicating efforts to control viral spread and ensure patient recovery.
Case presentation: We report the case of a patient who experienced two recurrent episodes of SARS-CoV-2 RNA and IgM positivity and viral shedding over 60 days during hospitalization.
Conclusions: This case report demonstrates that relapses of SARS-CoV-2 RNA and IgM positivity may occur even after COVID-19 symptoms have resolved, possibly as a consequence of prolonged viral shedding rather than re-infection.
Keywords: COVID-19; Coronavirus; IgM; Recurrence; SARS-CoV-2; Viral shedding.
