Coronavirus disease-19 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a global pandemic, giving rise to a serious global health threat. Many countries including Greece have seen a two-wave pattern of reported cases, with a first wave in spring and a second in autumn of 2020.
A cross-sectional seroprevalence study was designed to measure the prevalence of IgG antibodies with a quantitative SARS-CoV-2 IgG lab-based serology test, chemiluminescent microparticle immunoassay, against novel coronavirus in rural areas in Greece after the second pandemic wave. The study was conducted on 29 January 2021 in a rural semi-closed area, the municipality of Deskati, prefecture of western Macedonia in Greece after the second pandemic wave.
Sixty-nine participants were included in this study. The present study demonstrated a high prevalence of COVID-19 infection (31 of 69 total participants; 45%) and those who were working in the public sector were at higher risk of COVID-19 infection in comparison to their counterparts in private sector (p=0.05364), (relative risk 2.64; 95% confidence interval 1.001-7.086).
The study presents data showing a high prevalence of herd immunity for COVID-19 in a semi-closed area in Greece. These findings might help to understand the characteristics of this second wave, the behaviour and danger of SARS-CoV-2 in rural areas in Greece and Europe generally.
由严重急性呼吸系统综合征冠状病毒 2 型（SARS-CoV-2）引起的 2019 年冠状病毒病（COVID-19）已成为全球性大流行，对全球健康构成严重威胁。包括希腊在内的许多国家都出现了两波报告病例的模式，第一波出现在春季，第二波出现在 2020 年秋季。
本研究设计了一项横断面血清流行率研究，旨在使用基于实验室的 SARS-CoV-2 IgG 定量血清学检测、化学发光微粒子免疫分析，测量希腊农村地区第二波大流行后新型冠状病毒 IgG 抗体的流行率。该研究于 2021 年 1 月 29 日在希腊西部马其顿州德斯卡蒂市的一个农村半封闭地区进行。
本研究共纳入 69 名参与者。本研究显示 COVID-19 感染的高流行率（69 名参与者中共有 31 名；45%），与私营部门相比，公共部门的工作人员感染 COVID-19 的风险更高（p=0.05364），（相对风险 2.64；95%置信区间 1.001-7.086）。
本研究提供的数据显示，希腊半封闭地区 COVID-19 人群免疫力较高。这些发现可能有助于了解第二波疫情的特征、SARS-CoV-2 在希腊和欧洲农村地区的行为和危险。
