摘要
目的 分析云南省 1 991～ 2 0 0 0年疟疾发病态势 ,为疟疾防治措施的制定提供决策依据。方法 对 1 0年间云南疟疾发病、发热病人血检、流动人员管理以及媒介监测资料进行统计和流行病学分析。结果 1 0年间云南共报告疟疾病例 1 42 1 94例 ,2 0 0 0年疟疾年发病率为 2 .2 3 /万 ,比 1 991年的 4.83 /万下降了 5 3 .83 % ,发热病人共血检 61 83 85 3人次 ,检出疟疾病例 1 70 5 78例 ,血检阳性率为 2 .76% ,年血检阳性率在 1 .93 %～ 3 .3 0 %之间。在边境地区 ,不同流动人员的发热病人血检阳性率为 :外国入境边民 1 3 .0 5 % ;我国边民出境回归人员7.67% ;内地到边境地区流动人员 1 2 .45 %。经过 1 0年对媒介按蚊的监测和防制 ,2 0 0 0年微小、嗜人、昆明 3种不同媒介区的疟疾发病比 1 990年分别下降了 5 5 .3 7%、5 8.3 3 %、41 .1 5 %。结论 云南通过两个 5年疟疾防治规划的工作 ,疟疾发病呈逐年下降趋势 ,疟区范围渐步缩小。但疟疾流行形势仍然十分严峻。
Objective To analyse the malaria situation so as to provide scientifi c basis for working out malaria control program in Yunnan Province.Meth od Epide miological analysis on data of malaria incidence, blood examination in febrile c ases, management of transient population and vector surveillance from 1991 to 20 00 was made.Results In the 10 years’ period, a total of 142 19 4 malaria cases w ere reported. In 2000, the malaria incidence was 2.23/10000, with a reduction ra te of 53.83% than that in 1991 (4.83/10000). 170 578 malaria cases, with a posit i ve rate of 2.76%, were detected out from 6 183 853 person-times of blood exam inati on of febrile cases. The annual positive rates of blood examination were 1.93%~3 .31%. In border areas, the positive rates of blood examination in febrile cases from t ransient population were 13.05% in immigrating foreign frontier residents, 7.67% in domestic frontier resi dents, and 12.45% in inland transient population during 1991～1999. After 10 yea rs’ malaria vecto r control, the malaria incidence in three typical vector areas of An.minimum, An .anthropophagus and An.kunmingsis in 2000 were reduced by 55.37%, 58.33% and 41.1 5% than that in 1990. Conclusion After carried out two “5-yea r Malaria Control Program”, the annual malaria incidence was gradually decreased and the malaria transmission scope narrowed. However, the malaria situation in Yunnan Province is still serious.
