We screened stored samples collected before COVID-19 had been reported in Brazil. 989 samples were tested for SAR-CoV-2 antibodies using two different methods; 16 (1.6%) were positive (7 (43.8%) IgM, 3 (18.8%) IgG and 6 (37.5%) IgG/IgM positive), suggesting SARS-CoV-2 had circulated before the first reported COVID-19 case in Brazil.
