Abstract
We conducted 2 independent population-based SARS-CoV-2 serosurveys in Yaoundé, Cameroon, during January 27-February 6 and April 24-May 19, 2021. Overall age-standardized SARS-CoV-2 IgG seroprevalence increased from 18.6% in the first survey to 51.3% in the second (p<0.001). This finding illustrates high community transmission during the second wave of COVID-19.
摘要
我们在喀麦隆雅温得进行了 2 项独立的基于人群的 SARS-CoV-2 血清学调查，时间分别为 2021 年 1 月 27 日至 2 月 6 日和 4 月 24 日至 5 月 19 日。总体而言，年龄标准化的 SARS-CoV-2 IgG 血清阳性率从第一次调查的 18.6%上升到第二次调查的 51.3%（p<0.001）。这一发现表明在第二波 COVID-19 期间社区传播很高。
