目的:了解湖北省2004年疟疾流行态势,提出有效的防治措施。方法:收集2004年疟疾资料,对重点地区进行居民带虫率及蚊媒种类和密度调查。结果:全省共报告疟疾2687例,发病率0.45/万,比去年下降49.72%;嗜人按蚊疟区的18个县(市)发病2226例,占全省病例的82.84%,发病率1.37/万,比去年下降53.48%;3个县市出现局部暴发流行;中华按蚊疟区的63个县(市)发病461例,占全省病例的17.16%,发病率0.11/万,比去年下降17.53%。结论:全省疟疾疫情比2003年大幅度下降,流行范围进一步缩小,但向鄂西北移动。疟防工作的重点应放在老河口市和嗜人按蚊疟区的12个重点县(市、区),中华按蚊疟区要加强流动人口的监测,防止疟疾输入。
Objective: To understand the epidemic situation of malaria in Hubei Province in 2004 and put forward effective prevention and cure measures. Methods: The data of malaria in 2004 were collected and the prevalence of mosquito vectors and the species and density of mosquitoes were surveyed in key areas. Results: A total of 2687 cases of malaria were reported in the province, with a incidence of 0.45 per ten thousand, 49.72% less than last year. In 22 counties (cities) of the anopheles anthropophagus, 2226 cases were found, accounting for 82.84% of cases in the province with an incidence rate of 1.37 / Million, down 53.48% over last year; 3 outbreaks occurred in three counties and cities; 63 counties (cities) in the Anopheles sinensis malaria region 461 cases, accounting for 17.16% of the province’s cases, the incidence of 0.11 / million, Down 17.53%. Conclusion: The epidemic rate of malaria in the whole province dropped significantly compared with that in 2003, and the epidemic scope further narrowed, but moved to the northwest of Hubei Province. The focus of malaria prevention work should be placed on 12 key counties (cities and districts) in Laohekou and the Anopheles anthropophagus. The surveillance of the floating population should be strengthened in order to prevent malaria from being imported.
