2006年云南省疟疾流行情况及防控效果评价

目的评价云南省2006年疟疾流行形势及防控措施效果,为该省的疟疾防治提供参考依据。方法用Arc-View3.3及Microsoft excel 2007等软件对2006年疟疾流行形式进行分析和描述,并用疟疾发病率对防控措施的效果进行评价。结果信息系统报告疟疾疫情（不含外籍和港澳台）病例11 647例,发病率比2005年下降15.53%;发病率14个州（市）出现下降,2个州（市）上升,发病数前10位的县（市）有7个一线边境县,3个二线边境县;疟防报表发病率10以上的15个县,除2个二线边境县外均属一线边境。疟防报表报告疟疾（含外籍和港澳台）病例15 532例,仅比2005年上升1.13%（χ^2=0.84,P〉0.05）;当地感染病例增加18.23%;当地感染恶性疟病例增加12.08%;67.62%的疟疾病例发生在有流动史的人员中间,有流动史的当地居民疟原虫检出率显著高于无流动史者,境外和外省流动人员高于本省外县流动人员。用嗜人按蚊传播区疟疾防治对策处理该区域出现的疟疾大幅回升和输入性突发疫情,取得了较好的防控效果。结论2006年疟疾防控工作取得了预期成效。预计后4年的疟疾发病率会随着全球基金等疟疾控制项目工作的深入而继续下降。需加强流动人员疟疾监测和突发疫情处置,以防疟疾疫情继续回升或暴发。

Malaria prevalent situation and effect evaluation of malaria control measure in Yunnan Province in 2006

Objective To provide reference evidence for malaria control in the near future in Yunnan Province. Methods A wide-spread Malaria situation was analyzed and described using Microsoft excel 2007 and AreView GIS 3.3 software. The effects evaluation of malaria control measures were also carried out using malaria incidences. Results 11 647 cases reported by the Chinese information system for disease and prevention.. The incidences showed that 14 prefectures or cities were affected and the malaria incidences of another 2 prefectureson have been rise. All counties belonged to first line border area counties which ranged from the first 10 places of malaria incidences to 3 second line border area counties. 15 532cases reported malaria control was working form but the incidence only raised 1.13 % （Х^2= 0.84, P〉0.05）. Local infective cases and local infective faleiparum cases also increased 18.23% and 12.08% respectively compared with years up to 2005 according to malaria control working form. The parasite positive rate in the group who had a history of being mobile was obviously higher than the group which had no history of being mobile, and amoung the group from outside the country＇s border and other provinces of the country, the indidenee was higher than in the group from other counties of Yunnan Province. 5） Malaria control measures reduced the malaria incidence by 15.53% compared with those years up to 2005. Malaria control has made great strides by using the strategies selected for the areas where malaria incidence was higher than 10 per ten thousand population. The incidences of local cases to a great extent are on the rise again and sudden cases are occurring that seem to be imported from outside the country＇s border and within country＇s borders in the area with Anopheles anthropophagus as main Vector in Yunnan Province. Conclusion Anticipant effects have been obtained for malaria control work up to and including year 2006. Malaria incidence will continue to come down by projecting 4 years in advance
