摘要

我们估算了冲绳岛不同岛群抗 SARS-COV-2 IgG 的血清流行率。我们在 2020 年 7 月至 2021 年 2 月期间分三次重复进行了横断面血清调查。共收集了 2683 份血清样本,这些样本分别来自冲绳的六个转诊医疗中心。在本岛,第一次、第二次和第三次血清调查的血清流行率分别为 0.0%(0/392,95% CI:0.0-0.9)、0.6%(8/1448,0.2-1.1)和 1.4%(8/582,0.6-2.7)。在偏远岛屿,第二次和第三次血清调查的血清流行率分别为 0.0%(0/144,95% CI:0.0-2.5)和 1.6%(2/123,0.2-5.8)。在第三次调查中,主岛的病例检出率为 2.7(95% CI:1.3-5.3),偏远岛屿为 2.8(0.7-11.1)。病例检出率在本岛 20-29 岁人群中最高(8.3,95% CI:3.3-21.4),在偏远岛屿 50-59 岁人群中最高(14.1,2.1-92.7),这表明监测系统对这些亚群的临床病例报告不足。在新出现的传染病流行期间进行血清调查可提供病例检出率,有助于验证监测系统的可靠性。

SARS-CoV-2 IgG seroprevalence in the Okinawa Main Island and remote islands in Okinawa, Japan, 2020-2021.

We estimated the seroprevalence of anti-SARS-COV-2 IgG in different island groups in Okinawa. A cross-sectional sero-survey was repeated in three periods between July 2020 and February 2021. A total of 2683 serum samples were collected from six referral medical centers, each covering a separate region in Okinawa. In the main island, the seroprevalence was 0.0% (0/392, 95% CI: 0.0-0.9), 0.6% (8/1448, 0.2-1.1), and 1.4% (8/582, 0.6-2.7) at the 1st, 2nd, and 3rd sero-survey, respectively. In the remote islands, the seroprevalence was 0.0% (0/144, 95% CI: 0.0-2.5) and 1.6% (2/123, 0.2-5.8) at the 2nd and 3rd survey, respectively. The case detection ratio was 2.7 (95% CI: 1.3-5.3) in the main island and 2.8 (0.7-11.1) in the remote islands during the 3rd survey. The case detection ratio was the highest in people aged 20-29 years (8.3, 95% CI: 3.3-21.4) in the main island and in those aged 50-59 years (14.1, 2.1-92.7) in the remote islands, suggesting under-reporting of clinical cases by the surveillance system in these subgroups. A sero-survey during an emerging infectious disease epidemic can be useful for validating the reliability of the surveillance system by providing the case detection ratio.
