Abstract
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.

우리는 브라질에서 COVID-19가 보고되기 전에 수집된 저장된 샘플을 선별했습니다. 989개의 샘플을 두 가지 다른 방법을 사용하여 SAR-CoV-2 항체에 대해 테스트했습니다. 16명(1.6%)은 양성(7명(43.8%) IgM, 3명(18.8%) IgG 및 6명(37.5%) IgG/IgM 양성)으로, SARS-CoV-2가 첫 COVID-19 사례가 보고되기 전에 순환했음을 시사합니다. 브라질.
