粤桂琼流动人口疟疾管理19年广西片疟疾联防效果评价

Evaluation on effect of intersectional malaria control in Guangxi area of three-province cooperative malaria control in 1992～2010

目的分析粤桂琼流动人口联合管理区广西片1992～2010年疟疾监测结果,评价联防联控措施。方法收集1992～2010年广西片8县(区)当地居民发热病人、流动人口及重点人群疟疾间接荧光抗体(IFAT)监测资料进行流行病学描述和统计分析。结果 19年间广西片共血检当地发热病人78.8万人次,流动人口19.2万人次,两类人群血检阳性率分别为0.003%和0.38%,共检出疟疾病例759例,本地感染病例占总病例的3.69%(28/759),输入性病例占96.31%(731/759)。重点人群IFAT抗体阳性率为0.06%(211/373 825)。结论广西片参加三省疟疾联防19年来,疟疾年带虫发病率一直控制在1/万以下,1999年起至今无当地感染疟疾病例和输入继发病例发生,流动人口发热病人血检阳性率从1992年的3.23%降至2010年的0.029%,流动人口疟疾管理与监测措施有效,联防联控效果显著。

Objective To analyze the effect of intersectional malaria control and evaluate surveillance measure in Guangxi region among Guangdong,Guangxi and Hainan cooperative malaria control from 1992 to 2010.Methods The data on blood smear examination of febrile patients in local residents,mobile population and surveillance of IFAT in focus residents in 8 counties from 1992 to 2010 were collected,described and analyzed.Results The total of 788 685 and 192 290 slides of local residents and migrant population were examination.The average positive rates of blood examination were 0.003% and 0.38%,respectively.Total of 759 malaria cases were detected.The indigenous cases and imported cases accounted for 3.69%（28/759）and 96.31%（731/759）of the total malaria cases respectively.The positive rate of IFAT in focus residents was 0.06%（211/372 825）.Conclusion The malaria incidence in Guangxi area has been under 1/10 000 for 19 years.No indigenous cases and secondary cases of malaria found since 1999.The positive rate of slides in mobile population from 3.23% in 1992 down to 0.029% in 2010.The results show the present surveillance system and control programs are effective for monitoring the epidemic situation of malaria.
