目的分析北京口岸输入性虫媒传染病发病情况,为口岸监测的重点航班、重点人员范围的划定提供科学依据。方法对2014年1-4月北京口岸入境人员采取红外体温监测、医学巡查等传染病监测措施,分析输入性虫媒传染病传播情况。结果共发现输入性虫媒传染病共144例,其中疟疾阳性病例123例,登革热阳性病例21例。来自非洲的病例114例,占79.17%;劳务人员69例,占47.92%。乘坐ET604、SA288航班入境人数为142例,占总数98.61%。年龄在30~50岁之间,共96例,占总数66.67%。26例体温高于正常体温36.8℃,9例同时伴有不同的症状体征,以头痛、恶心、面色潮红最为明显。结论非洲地区和中国籍外派劳务人员已成为我国输入性虫媒传染病疫情的主要来源地和重点人群。ET604、SA288两架次入境航班应列为重点监督对象。输入型传染病易感人群为青壮年,符合虫媒传染病的一般特征。外派到非洲国家的劳务人员为高危人群,在非洲沿海地区感染及传播虫媒传染病风险较大。
Objective To analyze the incidence of imported zoonotic infectious diseases in Beijing Port and provide a scientific basis for the delineation of key flights and key personnel in port monitoring. Methods From January to April 2014, immigrants from Beijing Port were monitored by means of infrared body temperature monitoring and medical inspections, and the transmission of imported zoonotic diseases was analyzed. Results A total of 144 cases of imported zoonotic diseases were found, of which 123 cases were positive for malaria and 21 cases were positive for dengue fever. There were 114 cases from Africa, accounting for 79.17%, and 69 workers (47.92%). Take ET604, SA288 flight arrivals to 142 cases, accounting for 98.61% of the total. Aged between 30 to 50 years old, a total of 96 cases, accounting for 66.67% of the total. 26 cases of body temperature higher than the normal temperature of 36.8 ℃, 9 cases accompanied by different symptoms and signs to headache, nausea, flushing most obvious. Conclusion The dispatched laborers in Africa and China have become the main source and key population of the imported zoonotic infectious diseases in China. ET604, SA288 two entry flights should be listed as the focus of supervision. Infectious diseases susceptible to enter the population of young adults, in line with the general characteristics of zoonotic diseases. Labor dispatched to African countries are at high risk, with a greater risk of contracting and transmitting vector-borne diseases in the coastal areas of Africa.
