阜阳市1994—1999年肾综合征出血热监测结果分析

Analysis of HFRS Surveillance from 1994 to 1999 in Fuyang

我市是肾综合征出血热稳定的重要疫区 ,监测结果提示有Ⅰ型和Ⅱ型 (HFRS)存在可能 ;稳定重疫区集中在沿淮河水系的阜南、颍上、临泉、太和 ;发病高峰集中在冬季 ,占 49.2 0 % ;发病率逐年下降 ,一是以灭鼠为主综合性防治措施得到落实 ;二是在高发老疫区改变种植农作物 ,可能使鼠类生存、活动受到限制 ,鼠密度降低疫情下降 ;三是出血热疫苗预防接种保护了部分高危人群。但不能排除本病周期性的可能 。

Fuyang is a important stable area of HFRS. The results indicated that there existed two type HFRS possibly, type I and type II. Areas along Huai river, such as Funan, Yingshang, Linquan, Taihe, were main areas of HFRS. There was a high incidence of HFRS in winter. The cases in the season accounted for about 49.20% . The incidence was decreasing in the recent years. The reasons were as follow: Firstly, comprehensive measures around rat eradication had been administered; Secondly, crops in the area had been changed; Finally, high risk groups were protected by HFRS vaccine. Although the incidence decreased, the possibility of HFRS periodicity could not be excluded. Thus, surveillance and control of HFRS should be still strengthened.
