【摘要】 目的 评估2025年8月在我国（不含香港、澳门特别行政区和台湾地区，下同）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各省（自治区、直辖市）疾病预防控制中心专家参与评估。结果 2025年8月突发公共卫生事件数可能比7月有所增加，以传染病类事件为主。基孔肯雅热境外输入风险和广东省佛山市疫情溢出风险持续存在，Ⅰ、Ⅱ、Ⅲ类地区存在输入续发本地传播风险。8月七大江河流域全面进入主汛期，预计有2～3个台风登陆或影响我国，洪涝灾害受影响地区存在水源性、食源性疾病以及虫媒传染病发病率上升等公共卫生风险。登革热境外输入及跨地区传播风险上升，Ⅰ类地区及部分Ⅱ类地区发生聚集性疫情的风险较高。发热伴血小板减少综合征仍处于发病高峰期，病例以散发为主，存在人传人导致的聚集性疫情的风险。8月为高温中暑发生和死亡高峰，男性、婴幼儿和老年人是中暑的高风险人群。短期内猴痘Ⅱb亚分支疫情仍将保持低水平波动态势，Ⅰb亚分支在我国境内非洲裔人群中可能存在隐匿传播，存在向我国人群传播的风险。新型冠状病毒感染疫情将继续呈现下降或波动下降趋势。结论 对基孔肯雅热、洪涝灾害、登革热、发热伴血小板减少综合征、高温中暑、猴痘及新型冠状病毒感染等予以关注。更多还原

【Abstract】 Objective To assess the risk of public health emergencies that may occur or be imported from abroad in China(except Hong Kong and Macao Special Administrative Regions and Taiwan region, the same below) in August 2025.Methods Based on the reports of domestic and foreign public health emergencies and surveillance results of key infectious diseases or notifications from relative agencies and departments, the expert consultation conference was hold and experts from provincial(autonomous region and municipal) centers for disease control and prevention attended this conference through video terminal. Results It is predicted that the incidence of public health emergencies in August 2025 would be higher than that in July 2025. The main public health emergencies would be infectious diseases. There is a risk of chikungunya fever imported from abroad as well as epidemic spillover from Foshan, Guangdong, and Class Ⅰ, Ⅱ, and Ⅲ regions remain at risk of secondary local transmission from imported cases. In August, the basins of China’s seven major rivers will fully enter the main flood season, with 2-3 typhoons expected to make landfall or affect the country. Affected areas will face increased risks of public health issues such as increased incidence of waterborne, foodborne, and vector-borne diseases. There is a rising risk of dengue fever imported from abroad as well as transmitted across different regions in China. Class Ⅰ regions and some ClassⅡ regions are at high risk of clustered outbreaks. Severe fever with thrombocytopenia syndrome(SFTS) remains in its peak incidence period, with cases mainly sporadic, and there is a risk of clustered outbreaks caused by human-to-human transmission.August is the peak period for heatstroke occurrences and deaths, and men, infants, and the elderly are at higher risk. In the short term, the mpox clade Ⅱb epidemic in China will continue to maintain a low-level fluctuating trend. Sublineage Ⅰb may have caused hidden transmission among populations of African descent in China, with the potential to spread to the Chinese population. The coronavirus disease 2019(COVID-19) epidemic will continue to show a fluctuating downward trend in the coming period. Conclusion Attention should be paid to chikungunya fever, floods, dengue fever, SFTS, heatstroke, mpox,and COVID-19.更多还原
