Background The year 2020 was marked by the new coronavirus pandemic, resulting in millions of cases and deaths, placing healthcare workers at high risk of infection. Aims The aim of this study was to describe the role of an occupational health service during coronavirus disease 2019 pandemic in an oncologic hospital and characterize the most likely sources of viral infection. Methods The information of all healthcare workers with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection from 11 March to 15 December 2020 was collected through an epidemiological survey conducted during contact tracing. The data extracted included gender, age, comorbidities, occupational group, source of infection, clinical presentation, duration of the disease, need for hospitalization and persistent or late symptoms after disease or upon returning to work. Results Out of a total of 2300 workers, 157 were infected, consisting of nurses (36%), nurse assistants (33%) and diagnostic and therapeutic professionals (10%). Physicians and administrative staff accounted for 8% each. The most frequently reported source of infection was occupational (43%), owing to worker-to-worker transmission (45%) and patient-to-worker transmission (36%). The most frequent moments of infection perceived corresponded to the removal of protective equipment during meals and moments of rest in the staff and changing rooms. Conclusions The study revealed that occupational transmission from patients and colleagues might be an important source of SARS-CoV-2 infection in healthcare workers. Spread between colleagues accounted for 45% of the occupational source infections reported. Implementing physical distancing measures and limiting the number of people in changing and rest rooms could significantly reduce infection and related absenteeism.

接触 COVID-19 的医护人员的职业管理

背景 2020 年以新型冠状病毒大流行为标志，导致数百万病例和死亡，使医护人员处于感染高风险之中。目的 本研究的目的是描述职业卫生服务在 2019 年冠状病毒病大流行期间在肿瘤医院的作用，并描述最可能的病毒感染源。方法通过接触者追踪期间进行的流行病学调查，收集2020年3月11日至12月15日期间所有感染严重急性呼吸综合征冠状病毒2（SARS-CoV-2）的医护人员的信息。提取的数据包括性别、年龄、合并症、职业群体、感染源、临床表现、疾病持续时间、病后或重返工作岗位后需要住院治疗和持续或晚期症状。结果 在总共 2300 名工作人员中，有 157 人被感染，包括护士 (36%)、护士助理 (33%) 和诊断和治疗专业人员 (10%)。医师和行政人员各占8%。由于工人与工人之间的传播（45%）和患者与工人之间的传播（36%），最常报告的感染源是职业性的（43%）。感知到的最常见感染时刻对应于在用餐期间移除防护设备以及在工作人员和更衣室休息的时刻。结论 该研究表明，来自患者和同事的职业传播可能是医护人员感染 SARS-CoV-2 的重要来源。同事之间的传播占报告的职业源感染的 45%。实施身体距离措施并限制更衣室和洗手间的人数可以显着减少感染和相关的缺勤率。
