云南省澜沧江-湄公河上游维西县疟疾流行情况调查

目的了解维西县疟疾流行情况，为制定防治措施提供依据。方法收集维西县1997—2007年疟疾疫情资料，开展现场媒介和传染源调查，与专业人员座谈了解疟疾防治情况。结果维西县为澜沧江-湄公河上游疟疾流行起始地，1987年疟疾发病率高达50．31／万；该县近年疟疾下降但仍未达到控制标准，且有当地感染和输入病例；其主要媒介昆明按蚊占26．45％；当地有长潜伏期间日疟流行，在海拔1800m以上地区均有疟疾分布。结论维西县为不稳定性疟疾流行区。由于经费短缺、设备陈旧、缺乏疟疾镜检人员以及缺少疟疾现场防治管理技巧等因素，使当地疟疾患者得不到及时诊断和早期治疗。建议有关部门更多地关注维西县的疟疾防治，以便能够通过加强技术培训、提供设备和抗疟药品等措施，加强当地的疟疾控制能力。
