Patients with cancer are at a higher risk of developing serious disease-related complications in case of contracting SARS-CoV-2. Oncology units should implement all possible preventive measures to reduce the risk of viral transmission by healthcare professionals (HCPs) to patients. We conducted a surveillance for SARS-CoV-2 infection among the staff members of the Medical Oncology Unit of ASST Spedali Civili in Brescia, one of the Italian areas most affected by the SARS-CoV-2 pandemic. The aim of this study was to demonstrate whether the recommended preventive measures, promptly implemented by the unit, have been effective in reducing the spread of the virus among the HCPs. Between February 24 and May 19, 2020, SARS-CoV-2 infection was detected in 10 out of 76 healthy HCPs (13%). Six of them developed a symptomatic disease, leading to home quarantine, and four remained asymptomatic. The infection was revealed when a serology test was performed on all staff members of the unit. In seven HCPs, in which it was possible to trace the person-to-person infection, the contagion occurred as a result of unprotected contacts or partially protected with surgical masks. In particular, four asymptomatic HCPs did not stop working, but a widespread outbreak in the unit was avoided. Adherence to the recommended preventive strategies, in particular, wearing of surgical masks by both the HCPs and the patients, is effective in reducing and preventing the viral spread.
癌症患者感染严重急性呼吸综合征冠状病毒2（SARS-CoV-2）时发生严重疾病相关并发症的风险更高。肿瘤科室应采取一切可能的预防措施，以降低医护人员（HCP）将病毒传播给患者的风险。我们对意大利受SARS-CoV-2疫情影响最严重的地区之一布雷西亚市ASST斯皮达利奇维利医院肿瘤内科的工作人员进行了SARS-CoV-2感染监测。本研究的目的是证明该科室迅速实施的推荐预防措施是否有效地减少了病毒在医护人员中的传播。在2020年2月24日至5月19日期间，76名健康医护人员中有10人（13%）检测出SARS-CoV-2感染。其中6人出现症状性疾病，导致居家隔离，4人仍无症状。在对该科室所有工作人员进行血清学检测时发现了感染情况。在7名能够追踪到人际感染情况的医护人员中，感染是由于无防护接触或仅佩戴外科口罩的部分防护接触导致的。特别是，4名无症状医护人员并未停止工作，但该科室避免了疫情的广泛爆发。坚持推荐的预防策略，尤其是医护人员和患者都佩戴外科口罩，可有效减少和预防病毒传播。
