目的评价广西西南地区20个市、县灭疟联防区基本消灭疟疾前后防治效果。方法收集灭疟联防区各市县1982~2009年当地居民和流动人口疟疾监测资料,采用Excel软件进行统计分析。结果 1982~2009年该区域发现疟疾病人共11 464例,基本消灭疟疾前当地居民疟疾血检阳性率为0.67%,期间阳性率为0.05%,前后共发现恶性疟及混合感染患者共79例,1995年后未发现恶性疟患者,2003年后未发现疟疾患者。基本消灭疟疾前流动人口疟疾血检阳性率为14.75%,期间阳性率为2.55%,之后阳性率为0.31%,前后发现恶性疟及混合感染患者共260例。结论当地居民疟疾流行得到有效控制,流动人口疟疾患者一直存在,但未发现当地继发疟疾病例,因此,加强该区域疟疾监测尤为重要。
Objective To evaluate the prevention and treatment of malaria in malaria control areas in 20 cities and counties in southwestern Guangxi. Methods The malaria surveillance data of local residents and floating population from 1982 to 2009 in cities and counties in the anti-malaria zone were collected and statistically analyzed by Excel software. Results A total of 11 464 cases of malaria were found in the area from 1982 to 2009. The positive rate of malaria was 0.67% before malaria elimination. The positive rate was 0.05% during the period. A total of 79 cases of falciparum malaria and mixed infection were found before and after. No cases of falciparum malaria were found after 1995, and no malaria cases were found after 2003. The positive rate of malaria in the floating population before the basic elimination of malaria was 14.75%, the positive rate was 2.55% during the period and the positive rate was 0.31%. A total of 260 cases of falciparum malaria and mixed infection were found before and after. Conclusion Malaria prevalence among local residents is effectively controlled. Malaria patients in floating population are always present but no cases of secondary malaria are found in the local population. Therefore, it is particularly important to strengthen malaria surveillance in this area.
