First documentation of persistent SARS-CoV-2 infection presenting with late acute severe myocarditis.

A 64 year-old man presented with severe myocarditis 6 weeks after an initial almost asymptomatic SARS-CoV2 infection. He was found to have a persistent positive swab. Mechanisms explaining myocardial injury in patients with COVID-19 remains unclear, but this case suggests that severe acute myocarditis can develop in the late phase of COVID-19 infection, even after a symptom-free interval.
