The coronavirus disease 2019 (COVID-19) pandemic has become a worldwide public health crisis since December 2019. Reports of COVID-19 recurrences are uncommon but raise the question of whether patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) will develop lasting immunity against or whether there are multiple viral strains that need to be considered. Although severe disease typically occurs in older individuals with comorbidities, this case report describes a patient in this demographic group who presented with COVID-19 recurrence and remained relatively asymptomatic throughout both disease courses. This case highlights how SARS-CoV-2 appears to affect some patients unpredictably, indicating that more research is needed to further understand its viral pathophysiology and disease outcomes.
