- We report the first SARS-CoV-2 reinfection case, from southeast Brazil separated by a 225-day interval.

- The two COVID-19 episodes, were caused by genetically distinct SARS-CoV-2 agents, including the emerging B.1.2 lineage.

- Our findings reinforce that previous exposure to SARS-CoV-2 might not guarantee long-lasting immunity in all cases.
