医务人员新型冠状病毒肺炎感染的危险因素评估及防控对策

Risk Factors Assessment and Prevention and Control Strategy of COVID-19 Infection in Medical Staff

新型冠状病毒肺炎是目前蔓延全球的一种呼吸道感染病原体,全球范围内累计确诊病例超过2亿。流行病学数据显示,新型冠状病毒肺炎的传播途径包括飞沫、密切接触和封闭条件下的气溶胶传播。作为新型冠状病毒肺炎疫情防控的一线医务人员,属于感染患者的密切接触者,也是病毒感染的高危人群。由于病毒变异株出现于世界多个国家和地区,了解医务人员新型冠状病毒肺炎感染的风险因素并以此为基础制订防控对策,不仅能够最大限度地保证一线医务人员的安全,同时也是保护疫情防控成果的关键。

Novel coronavirus pneumonia is a respiratory pathogen infection that currently spreads all over the world,with more than 200million confirmed cases worldwide.Epidemiological data show that the transmission routes of COVID-19 include droplets,close contact and aerosol transmission under closed conditions.As the first-line medical staff in the prevention and control of COVID-19,they are close contacts of infected patients and high-risk groups of virus infection.As the virus variant strains appear in many countries and regions in the world,understanding the risk factors of COVID-19 infection among medical staff and formulating prevention and control strategies on this basis can not only ensure the safety of front-line medical staff to the greatest extent,but also protect the results of epidemic prevention and control.
