Background Healthcare workers (HCWs) can be a source of SARS-CoV-2 within long-term care facilities (LTCFs); therefore, we analysed the data from a testing programme among LTCF employees. Aims The aim of this study was to investigate the prevalence of SARS-CoV-2 and its determinants among employees of LTCFs and the risk for fellow workers and residents. Methods Testing started at week 15, the first wave’s peak, using nasopharyngeal swabs for PCR up to week 23. At the start of the second wave (week 32), testing resumed. Results A total of 32 457 test results were available from 446 LTCFs: 2% were positive: 1% in men, 2% in women, 2% in HCWs (=having patient contact), 1% in non-HCWs, higher in younger age groups. In total, 30 729 employees were tested once, 823 twice, 66 thrice and 4 four times. Prevalence was 13% during the first week of testing (week 15) and declined to 7% (week 16) to stay at around 1% (from week 17 until week 23). At the start of the second wave (week 31–33), the prevalence was around 3%. In 70% of positive tests, the employee was asymptomatic. Conclusions Our study confirms the presence of HCWs with SARS-CoV-2 as a possible source of infection in LTCFs even when the incidence in the general population was low; 70% were asymptomatic. To control the spread of SARS-CoV-2 in LTCFs vaccination, infection prevention and control measures are necessary as well as testing of all LTCF HCWs during possible outbreaks, even if asymptomatic.

长期护理机构中比利时工人的 SARS-CoV-2 流行率

背景 医护人员 (HCW) 可能是长期护理机构 (LTCF) 中 SARS-CoV-2 的来源;因此,我们分析了来自 LTCF 员工测试计划的数据。目的 本研究的目的是调查 SARS-CoV-2 在 LTCF 员工中的流行情况及其决定因素,以及同事和居民面临的风险。方法 检测从第 15 周开始,即第一波的高峰期,使用鼻咽拭子进行 PCR 直至第 23 周。在第二波开始时(第 32 周),检测恢复。结果 446 名 LTCF 共有 32 457 项检测结果:2% 为阳性:男性 1%,女性 2%,HCW 2%(=与患者接触),非 HCW 1%,年轻人更高年龄组。总共有 30 729 名员工接受了一次测试,823 人接受了两次测试,66 人接受了三次测试,4 人接受了四次测试。在测试的第一周(第 15 周)流行率为 13%,然后下降到 7%(第 16 周),保持在 1% 左右(从第 17 周到第 23 周)。在第二波开始时(第 31-33 周),患病率约为 3%。在 70% 的阳性测试中,该员工没有症状。结论 我们的研究证实,即使在普通人群的发病率较低的情况下,携带 SARS-CoV-2 的医护人员也可能是 LTCF 的感染源;70% 无症状。为了控制 SARS-CoV-2 在 LTCF 疫苗接种中的传播,必须采取感染预防和控制措施,并在可能爆发期间对所有 LTCF 医护人员进行检测,即使没有症状。该员工无症状。结论 我们的研究证实,即使在普通人群的发病率较低的情况下,携带 SARS-CoV-2 的医护人员也可能是 LTCF 的感染源;70% 无症状。为了控制 SARS-CoV-2 在 LTCF 疫苗接种中的传播,必须采取感染预防和控制措施,并在可能爆发期间对所有 LTCF 医护人员进行检测,即使没有症状。该员工无症状。结论 我们的研究证实,即使在普通人群的发病率较低的情况下,携带 SARS-CoV-2 的医护人员也可能是 LTCF 的感染源;70% 无症状。为了控制 SARS-CoV-2 在 LTCF 疫苗接种中的传播,必须采取感染预防和控制措施,并在可能爆发期间对所有 LTCF 医护人员进行检测,即使没有症状。
