The novel coronavirus disease 2019 (COVID-19) that has emerged as a pandemic now has put health care workers (HCWs) at great risk as they are the warriors in frontlines screening and treating the infected patients. When a COVID-19-positive HCW is identified, its contacts need to be traced to check the spread of the infection among patients and other HCWs.
This study was aimed to study epidemiology and risk factors associated with severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) infection among HCWs and to quantify the risk of infection among HCWs in a tertiary level health care setting.
This cross-sectional study enrolled all the HCWs who were exposed to a patient with COVID-19 in a tertiary level health care center, Rishikesh, Uttarakhand from 1 May to 30 July, 2020.
All the exposed HCWs were followed up for 14 days after the last exposure to a patient with confirmed COVID-19 infection. Epidemiological data were obtained using structured interviews.
The data were analyzed using SPSS 23.0. Frequencies and proportions were calculated for descriptive variables, and risk ratios were calculated for risk factors affecting the transmission of disease.
We observed that 1,141 HCWs of the tertiary level health care hospital were exposed to COVID-19 patients during the study period. A total of 22 HCWs were tested COVID-19 positive among these exposed HCWs. Univariate analysis revealed a high risk of exposure to be significantly associated with a higher secondary attack rate of SARS CoV-2.
The study demonstrates the risk of COVID-19 transmission through asymptomatic carriers. Therefore, periodic testing of all health care workers is necessary to ensure early mitigation of the shortage of health care providers.
2019年新型冠状病毒病（COVID-19）已演变成一场大流行病，医护人员面临着巨大风险，因为他们是筛查和治疗感染患者的一线战士。当发现一名医护人员COVID-19检测呈阳性时，需要追踪其接触者，以检查感染在患者和其他医护人员中的传播情况。
本研究旨在研究医护人员中与严重急性呼吸综合征冠状病毒2（SARS-CoV-2）感染相关的流行病学和危险因素，并量化三级医疗保健机构中医护人员的感染风险。
这项横断面研究纳入了2020年5月1日至7月30日期间在北阿坎德邦瑞诗凯诗的一家三级医疗保健中心接触过COVID-19患者的所有医护人员。
所有接触过的医护人员在最后一次接触确诊COVID-19感染患者后接受了14天的随访。通过结构化访谈获取流行病学数据。
使用SPSS 23.0对数据进行分析。计算描述性变量的频率和比例，并计算影响疾病传播的危险因素的风险比。
我们观察到，在研究期间，该三级医疗保健医院的1141名医护人员接触了COVID-19患者。在这些接触过的医护人员中，共有22人COVID-19检测呈阳性。单因素分析显示，高暴露风险与SARS-CoV-2较高的二代发病率显著相关。
该研究证明了COVID-19通过无症状携带者传播具有风险。因此，有必要对所有医护人员进行定期检测，以确保尽早缓解医护人员短缺的问题。
