2000—2012年贵州省榕江县疟疾流行病学特征

目的通过分析榕江县2000-2012年疟疾流行病学特征，为该县消除疟疾行动计划提供依据。方法收集该县2000-2012年疟疾防治资料，包括疟疾疫情报告、各乡镇卫生院疟疾诊断和治疗等资料，采用Excel软件进行统计和分析。结果2000-2012年该县疟疾病人群年均发病率为1．70／万，2000-2006年期间人群年发病率在0．09～1．48／万之间。2007-2010年疟疾病例数有所增加，人群年发病率在I．83—6．91／万之间，除1例为流动人口疟疾病例外，全部为当地居民疟疾病例。发病高峰期在6—10月份之间。疟疾病例以农民为主，分布于各种职业及各年龄组。全县19个乡镇仅2个乡镇未发现疟疾病例，未发现恶性疟病例及疟疾死亡病例。自2010年开展消除疟疾行动计划以来，疟疾病例逐年减少，2012年当地居民及流动人口中均未发现疟疾病例。结论该县近几年疟疾防治效果明显，但仍需加强当地居民及流动人口的疟疾病例监测。

Epidemiological characteristics of malaria in Rongjiang County of Guizhou Province from 2000-2012

Objective ] To analyze the epidemiological characteristics of malaria in Rongjiang County from 2000-2012, and provide evidence for action plan of malaria elimination.

The annual incidence was between 0.09/10 000-1.48/10 000 from 2000-2006. Due to the increasing number of malaria cases, the annual incidence was up to 1.83/10 000 - 6.91/10 000 during 2007-2010. Except for 1 case of floating people, the rest cases were local residents. The peak incidence appeared in June- October. Most cases were peasants of different occupation and age.
