目的评估2017年9月国内外突发公共卫生事件及需要关注传染病的风险。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(直辖市、自治区)疾病预防控制中心专家参与评估。结果根据既往监测数据,预计9月全国总体的突发公共卫生事件数和病例数较8月有所上升,主要与学校开学后常见传染病事件逐渐增加有关。国内多地暴发本地传播的登革热疫情,随着人员流动,有媒介伊蚊分布的省份本地传播风险也将上升;而基孔肯雅热、寨卡病毒病等其他蚊媒传染病也存在输入性病例和输入后发生本地传播的风险。人感染H7N9禽流感将继续出现散发病例。9月仍然是食物中毒高发期,且毒蘑菇中毒往往是引起死亡的主要原因。南方地区的季节性流感仍处于高位,北方地区流感水平处于较低水平,但随着学校开学,暴发疫情将增多。中东呼吸综合征存在输入的可能,但大规模传播的风险极低。2017年夏季我国流行性乙型脑炎(乙脑)疫情有所升高,但目前疫情已经处于下降趋势。结论预计2017年9月我国的突发公共卫生事件数将有所上升;需特别关注登革热、寨卡病毒病、基孔肯雅热等蚊媒传染病,重点关注人感染H7N9禽流感,一般关注食物中毒、季节性流感和中东呼吸综合征,了解乙脑疫情的风险。
Objective To assess the public health emergencies at home and abroad in September 2017 and the need to pay attention to the risk of infectious diseases. Methods According to the reports of domestic and foreign public health emergencies and the monitoring of key infectious diseases, the expert consultation method was adopted to invite experts from provincial (municipalities and autonomous regions) CDC to participate in the assessment through video conferencing. Results Based on past monitoring data, the number of public health emergencies and the number of cases in the nation as a whole are expected to increase in September compared with August, mainly due to the gradual increase of common communicable diseases after school starts. Domestic outbreaks of endemic dengue outbreaks in many places in China have also increased the risk of local transmission of Aedes albopictus along with the movement of personnel. Other imported mosquito-borne diseases, such as Chikungunya, Zika virus disease, Case and risk of local transmission after entry. Human infection with H7N9 bird flu will continue to occur in sporadic cases. September is still the period of high incidence of food poisoning, and poisoning of mushrooms is often the main cause of death. Seasonal influenza in the south is still high, while flu in the north is at a low level, but outbreaks will increase as the school opens. Middle East respiratory syndrome may be imported, but the risk of large-scale transmission is extremely low. In the summer of 2017, the epidemic rate of Japanese encephalitis (JE) in our country has risen, but at present the epidemic has been on a downward trend. Conclusions It is estimated that the number of public health emergencies in our country will increase in September 2017. Special attention should be given to mosquito-borne infectious diseases such as dengue fever, Zika virus disease and chikungunya fever, with a focus on people infected with H7N9 bird flu, with a general concern Food poisoning, seasonal flu and Middle East Respiratory Syndrome (SARS) and to understand the risks of the JE outbreak.
