2022年4月中国大陆需关注的突发公共卫生事件风险评估

  目的  评估2022年4月在我国大陆地区发生或者可能由境外输入的突发公共卫生事件风险。  方法  根据国内外突发公共卫生事件报告及重点传染病监测等各种资料和部门通报信息，采用专家会商法，并通过视频会议形式邀请省（自治区、直辖市）疾病预防控制中心专家参与评估。  结果  预计4月国内报告新型冠状病毒肺炎（新冠肺炎）以外突发事件总数将与3月持平。 本土新冠肺炎疫情在境内的传播扩散以及境外疫情输入导致本土疫情发生的风险很高，疫情防控难度加大，各地需要按照国家要求加强疫情防控工作，防止疫情规模性反弹。 百日咳由于实验室检测技术提高、疫苗保护效力的减弱以及部分地区加强监测等因素的影响，其报告病例数仍将保持上升趋势。  结论  特别关注新冠肺炎，一般关注百日咳。

Risk assessment of public health emergencies concerned in the mainland of China,April 2022

  Objective  To assess the risk of public health emergencies, both the indigenous ones and the imported ones, which might occur in the mainland of China in April 2022.   Methods  An internet based expert counsel was conducted to analyze the surveillance data of public health emergencies and priority communicable diseases in China reported through different channels, and the experts in all provincial centers for disease control and prevention attended this video conference.   Results  It is expected that number of domestically reported public health emergency events other than COVID-19 in April would remain unchanged from March. The risk of domestic COVID-19 outbreaks caused by the indigenous transmission and the foreign importation is high, making it more difficult to prevent and control the epidemic. Local governments need to strengthen epidemic prevention and control in accordance with national requirements and hold the bottom line of no large-scale rebound of the epidemic. The number of pertussis cases will maintain rising trend due to the improvement of laboratory testing technology, the weakening of vaccine protection and the strengthening of surveillance in some districts.   Conclusion  Special attention should be paid to COVID-19. General attentions should be paid to pertussis.
