Understanding COVID-19 infection among health workers and the risk factors for adverse outcomes is important not only for characterizing virus transmission patterns and risk factors for infection, but also for preventing the future infection of health workers and other patients and reducing secondary COVID-19 transmission within health care settings. Our aim was to identify risk factors for infection among health care workers to limit adverse events in health care facilities.
A total of 336 HCWs from COVID-19 treatment hospitals took part in the study with varying COVID-19 exposure risk depending on job function and working site. All participants were asked about risk factors for COVID-19 infection.
Among our participants, 42.6% were medical doctors, 28.6% nurses and 7.4% assistant nurses and 21.4% were others. Forty four percent of participants had work experience 5-10 years. More than half of participants received training in Infection Prevention and Control (IPC) (56.8%) about COVID 19; 91% have hand hygiene facilities and 69% admitted availability of PPE. More than half of participants admitted that they always follow IPC measures. Two thirds of participants (66.7%) had close contact with a patient since admission; 42.3% were present in aerosolizing procedures for patients. Forty two percent of participants had respiratory symptom; the most common was sore throat representing (32.4%). The highest frequency of respiratory symptoms was among of nurses and assistant nurses 51%. Frequency of respiratory symptoms was higher among those who contacted the patient directly or for prolonged period compared to those who do not admitted these contacts.
Risk factors for COVID-19 represented by those who were smokers, nurses and assistant nurses were more liable to catch COVID-19 than doctors as they contacted the patient directly for prolonged period or his/her body fluids, materials or surfaces around him.
了解医护人员中的 COVID-19 感染情况以及不良结局的危险因素，不仅对于描述病毒传播模式和感染危险因素很重要，而且对于预防医护人员和其他患者未来感染以及减少医疗机构内 COVID-19 的二次传播也很重要。我们的目的是确定医护人员感染的危险因素，以限制医疗机构中的不良事件。
共有 336 名来自 COVID-19 治疗医院的医护人员参与了这项研究，他们的 COVID-19 暴露风险因工作职能和工作地点而异。所有参与者都被问及 COVID-19 感染的危险因素。
在我们的参与者中，42.6%是医生，28.6%是护士，7.4%是助理护士，21.4%是其他人员。44%的参与者有 5-10 年的工作经验。超过一半的参与者接受了关于 COVID-19 的感染预防和控制 (IPC) 培训（56.8%）；91%有手部卫生设施，69%承认有个人防护设备 (PPE)。超过一半的参与者承认他们始终遵守 IPC 措施。三分之二的参与者（66.7%）自入院以来与患者有密切接触；42.3%参与了对患者的气溶胶化处理。42%的参与者有呼吸道症状；最常见的是喉咙痛（占 32.4%）。呼吸道症状的最高频率出现在护士和助理护士中，为 51%。与那些直接接触患者或接触时间较长的患者相比，有呼吸道症状的患者更有可能接触到 COVID-19。
COVID-19 的危险因素是指那些吸烟者、护士和助理护士，他们比医生更容易感染 COVID-19，因为他们直接接触患者或患者的体液、材料或周围的表面时间更长。
