Understanding the burden of SARS-CoV-2 infections among healthcare workers is a critical component to inform occupational health policy and strategy. We conducted a systematic review and meta-analysis to map and analayse the available global evidence on the prevalence of SARS-CoV-2 infections among healthcare workers. The random-effects adjusted pooled prevalence of COVID-19 among those studies that conducted the test using the antibody (Ab) method was 7% [95% CI: 3 to 17%]. The random-effects adjusted pooled prevalence of COVID-19 among those studies that conducted the test using the PCR method was 11% [95% CI: 7 to 16%]. We found the burden of COVID-19 among healthcare workers to be quite significant and therefore a cause for global health concern. Furthermore, COVID-19 infections among healthcare workers affect service delivery through workers' sick leave, the isolation of confirmed cases and quarantine of contacts, all of which place significant strain on an already shrunken health workforce.
了解医护人员中新型冠状病毒2型（SARS-CoV-2）感染的负担是为职业健康政策和战略提供信息的关键组成部分。我们进行了一项系统评价和荟萃分析，以梳理和分析全球范围内关于医护人员中SARS-CoV-2感染患病率的现有证据。在那些使用抗体（Ab）方法进行检测的研究中，新型冠状病毒病（COVID-19）经随机效应调整后的合并患病率为7%[95%置信区间：3%至17%]。在那些使用聚合酶链反应（PCR）方法进行检测的研究中，COVID-19经随机效应调整后的合并患病率为11%[95%置信区间：7%至16%]。我们发现医护人员中COVID-19的负担相当严重，因此值得全球关注。此外，医护人员感染COVID-19会通过工作人员病假、确诊病例隔离和接触者检疫影响服务提供，所有这些都会给本已缩减的卫生人力带来巨大压力。
