Analyses of malaria in 24 epidemic counties in Guizhou and Guangxi provinces,the zone of antimalaria cooperation,in 2008—2009

目的分析2008～2009年黔桂两省灭疟联防区24个县疟疾流行动态,为联防区疟防工作提供参考。方法收集24县当地居民和流动人口"三热"病人疟原虫血检资料和临床诊断为疟疾并经抗疟药物治疗有效病例资料,采用Excel软件进行统计分析。结果两省灭疟联防区24个县两年疟疾人群发病率控制在2.29/万,贵州为4.13/万,广西为0.06/万,当地居民未发现恶性疟病例,无疟疾爆发点。贵州以当地居民疟疾病例为主,两年在当地居民中发现疟疾病例共1 759例。广西疟疾病例以流动人口为王,两年在流动人口中发现疟疾病例共19例,其中恶性疟5例,均为在东南亚国家感染后带回当地,脑型疟死亡病人1例。结论该区域疟疾疫情得到有效控制。

Objective To analyze the data on malaria in 24 epidemic counties, the zone of antimalaria cooperation, in Gnizhou and Guangxi provinces in 2008-2009, and to provide information for malaria control. Methods Data on the blood test for parasites in the residents and the ＂three hot＂ patients and on the clinical di- agnosis for malaria through antimalarial drug treatment were collected. Excel statistical software was used for statistical analyses. Results During the last 2 years, the incidence rate was controlled at 2.29/10 000 with 4.13 / 10000 in Gnizhou and 0.06/10000 in Guangxi . Plasmodium fcdciparum was not found in the one, neither malaria outbreaks. The cases of malaria in Guizhou were mainly from the local population with a total of 1 759 observed in the 2 years. Nineteen cases in Guangxi were mainly from the mobile population, from which 5 cases were Plasmodiumfalciparum due to the infection in Southeast Asian countries. One case with Plosmodium fcdciparum died of cerebral malaria. Conclusion The incidence of malaria in the zone has been under effective control. However, the involved provinces should focus on some particular aspects.
