The COVID-19 pandemic is placing considerable pressure on health services around the world. In Norway, the incidence rate among the working-age population (20-69 years) for the whole of 2020 was 1.11 %. In this study, we describe diagnosed infection among staff in the health service, based on register data.
From the emergency preparedness register, Beredt C19, we identified 382 332 persons employed in selected occupational groups in the health service in week 9 of 2020, and investigated incidence and testing activity for diagnosed SARS-CoV-2 according to occupation, age, sex, country of birth, place of residence and place of work, for the whole of 2020.
The incidence in the health service for the entire period was 1.48 % (5673/382 332). Diagnosed infection was highest among ambulance personnel and nursing home staff, with an incidence of 1.83 % (95/5203) and 1.86 % (1534/82 776), respectively. Doctors were tested most frequently (1.45 tests per person), and the proportion of positive tests was highest among cleaners (2.78 %) and ambulance personnel (1.57 %). Imported infection was highest for dentists (14.3 %), psychologists (12.8 %) and doctors (10.8 %).
There are variations in the incidence of diagnosed infections among employees in the health service. Some of this can likely be viewed in connection with high testing activity, imported infection, age and sex distribution, place of residence and country of birth, and outbreaks in different health services. More research and data are needed to ascertain whether occupational practice is associated with increased risk of SARS-CoV-2 infection.
COVID-19 大流行给全球卫生服务带来了巨大压力。在挪威，2020 年整个工作年龄段（20-69 岁）的发病率为 1.11%。在这项研究中，我们根据登记数据描述了卫生服务人员中的确诊感染情况。
我们从应急准备登记处（Beredt C19）中确定了 2020 年第 9 周在选定职业群体中就业的 382332 人，并根据职业、年龄、性别、出生地、居住地和工作地调查了 2020 年全年 SARS-CoV-2 确诊感染的发病率和检测活动。
整个时期卫生服务部门的发病率为 1.48%（5673/382332）。救护车人员和养老院工作人员的确诊感染率最高，发病率分别为 1.83%（95/5203）和 1.86%（1534/82776）。医生的检测频率最高（每人 1.45 次），清洁工（2.78%）和救护车人员（1.57%）的阳性检测比例最高。牙医（14.3%）、心理学家（12.8%）和医生（10.8%）的输入性感染率最高。
卫生服务部门员工确诊感染的发病率存在差异。其中一些可能与高检测活动、输入性感染、年龄和性别分布、居住地和出生地以及不同卫生服务机构的疫情有关。需要进一步的研究和数据来确定职业实践是否与 SARS-CoV-2 感染风险增加有关。
