摘要
目的分析广西2017年输入性疟疾疫情特征,为针对性防控提供依据。方法收集2017年广西流动人口疟疾监测数据,对输入性疟疾病例流行病学调查资料进行描述性分析。结果2017年广西共报告疟疾病例382例,均为国外输入性,病例数比2016年(305例)增加了25.25%;虫种为恶性疟233例(60.99%)、卵形疟107例(28.01%)、间日疟23例(6.02%)、三日疟6例(1.57%)、混合感染13例(3.40%);病例分布于区内12个地市28个县市(区),其中上林县病例数占病例总数的75.92%;病例以男性为主,为371例(97.12%);21~50岁青壮年病例378例(98.95%);病例感染来源于非洲19个国家381例(99.74%)、东南亚1个国家1例,其中非洲病例主要以加纳为主,为220例(57.59%),其次为喀麦隆49例(12.83%)和埃塞俄比亚21例(5.50%),东南亚国家仅有印度尼西亚;病例所从事职业主要以淘金/挖矿为主,为315例(82.46%),其次是经商/服务20例(5.24%);病例月分布为5月62例(16.23%),4~7月病例201例(52.62%)。全区出现2例输入性恶性疟死亡病例,无输入性继发病例发生。结论广西境外输入性疟疾疫情严峻,加强多部门合作、多途径摸排流动人口相关信息,加大对出国返乡人员疟疾监测力度,加强业务培训,同时加强外出务工人群疟防治知识健康宣教是有效控制输入性疟疾疫情的重要措施。
Objective To analyze the characteristics of imported malaria in Guangxi in 2017,and to provide a basis for targeted prevention and control.Methods Malaria surveillance data of migrant population in Guangxi in 2017 were collected,and epidemiological survey data of imported malaria cases were descriptive analyzed.Results In 2017,a total of 382 malaria cases were reported in Guangxi,all of which were imported from abroad.The number of cases increased by 25.25%compared with that in2016(305 cases).The species included 233 cases of falciparum malaria(60.99%),107 cases of ovale malaria(28.01%),23 cases of vivax malaria(6.02%),6 cases of malariae malaria(1.57%),and 13 cases of mixed infection(3.40%).The cases were distributed in 28 counties(districts)in 12 prefectures and cities,among which the number of cases in Shanglin County accounted for 75.92%of the total cases.The cases were predominantly male,with 371 cases(97.12%).378 cases(98.95%)of young adults aged 21~50 years old.Case infections originated from 381 cases(99.74%)in 19 countries in Africa and 1 case in 1 country in Southeast Asia.Among them,African cases were mainly in Ghana,220 cases(57.59%),followed by Cameroon in 49 cases(12.83%)and Ethiopia in 21 cases(5.50%).Indonesia was the only country in Southeast Asia.The main occupation of the cases was gold panning/mining(315 cases,82.46%),followed by business/service(20 cases,5.24%).The monthly distribution of cases was 62 cases(16.23%)in May and 201 cases(52.62%)in April^July.There were 2 imported falciparum malaria deaths in the whole region,and no imported secondary cases occurred.Conclusion In view of the severe imported malaria epidemic situation in Guangxi,it is important measures to strengthen multi-sector cooperation and multi-channel information collection of migrant population,increase surveillance of malaria among those returning from abroad,and strengthen technical training for medical personnel for effectively controlling the imported malaria epidemic.At the same time,strengthening malaria prevention knowledge and health education for migrant workers is an effective measure to control the input of malaria epidemic outbreak.
