福建省1980～1994年疟疾分布特征探讨

Distinguishing Features of Malarial Case Distribution during 1980～1994 in Fujian

１９８０～１９９４年福建省疟疾发病率指数曲线呈下降趋势，近９年发病率均在１／万以下。统计学检验提示，近年发病率呈随机性，有向上反弹的可能。目前本省疟疾病例的地区分布具“北降南升”态势。以嗜人按蚊为主要媒介的疟区，疫情稳定下降；以微小按蚊为传疟媒介的地区，尤其是闽南的厦门、漳州、泉州的“三角”地带疟情不稳，进入９０年代后发病数呈上升势头。由此提示我省的疟疾控制策略应作相应调整。今后若干年内应视微小按蚊生态习性和分布范围的变化，确定我省疟防重点区域，进一步加强闽南“三角”地带的疟疾防治与监测。

This paper described that,in a pattern of exponential function, malaria incidence in Fujian reduced over 15 years(1980-1994).Since 1985,the rate has been kept under one per ten thousandth population.But in the case-reporting area it is possible for malaria to increase again in some areas of Fujian.Since the beginning of 1990's,the number of malaria in triangle region,Xiamen,Quanzhou and Zhangzhou,where An.minimum is regarded as the main malaral vector,has been larger than north area in Fujian.The priority for malaria control should pay attention to ecological surveillance of the vector and the control of infection reservoir in triangle region.
