医院内传播是SARS-CoV-1和MERS-CoV暴发的重要方面。在英格兰的单一和多中心医院研究中报告了医疗保健相关的SARS-CoV-2感染,但在全国范围内没有报告。英格兰所有医院的入院记录都与2020年3月1日至2020年8月31日期间的SARS-CoV-2国家测试数据相关联。病例定义为:社区发病的社区获得性,入院前<14天首次检测阳性,直至入院第2天;医院发病的不确定的医疗保健相关性,第3-7天首次检测阳性;医院发病的可能医疗保健相关性,第8-14天首次检测阳性;医院发病的明确医疗保健相关性,从入院第15天至出院首次检测阳性;社区发病可能与医疗保健相关,出院后≤14天首次检测阳性。所有实验室确诊的COVID-19病例中有三分之一(34.4%,100,859/293,204)与医院记录有关。在住院患者中,医院发病的可能和确诊病例占所有实验室确诊病例的5.3%(15,564/293,204),占实验室确诊病例的15.4%(15,564/100,859)。社区发病的社区获得性和社区发病的可能与卫生保健有关的病例分别占所有实验室确诊病例的86.5%(253,582/293,204)和5.1%(14,913/293,204)。在大流行的前6个月,英格兰住院的COVID-19患者中高达六分之一的SARS-CoV-2感染可归因于医院传播,但这在此期间估计的300万COVID-19病例中占不到1%。
Nosocomial transmission was an important aspect of SARS-CoV-1 and MERS-CoV outbreaks. Healthcare-associated SARS-CoV-2 infection has been reported in single and multi-site hospital-based studies in England, but not nationally. Admission records for all hospitals in England were linked to SARS-CoV-2 national test data for the period 01/03/2020 to 31/08/2020. Case definitions were: community-onset community-acquired, first positive test <14 days pre-admission, up to day 2 of admission; hospital-onset indeterminate healthcare-associated, first positive on day 3–7; hospital-onset probable healthcare-associated, first positive on day 8–14; hospital-onset definite healthcare-associated, first positive from day 15 of admission until discharge; community-onset possible healthcare-associated, first positive test ≤14 days post-discharge. One-third (34.4%, 100,859/293,204) of all laboratory-confirmed COVID-19 cases were linked to a hospital record. Hospital-onset probable and definite cases represented 5.3% (15,564/293,204) of all laboratory-confirmed cases and 15.4% (15,564/100,859) of laboratory-confirmed cases among hospital patients. Community-onset community-acquired and community-onset possible healthcare-associated cases represented 86.5% (253,582/293,204) and 5.1% (14,913/293,204) of all laboratory-confirmed cases, respectively. Up to 1 in 6 SARS-CoV-2 infections among hospitalised patients with COVID-19 in England during the first 6 months of the pandemic could be attributed to nosocomial transmission, but these represent less than 1% of the estimated 3 million COVID-19 cases in this period.
