新疆喀什黑热病高流行区患者流行病学特征分析

Analysis of the epidemiological profile of visceral leishmaniasis in Kashgar,Xinjiang,China where the disease is highly endemic

目的掌握新疆喀什黑热病高流行区的黑热病发病特征,为该病的防控工作提供参考和依据。方法在喀什地区伯什克拉姆乡选取近年来黑热病发病人数位居前3位的3个大队进行入户普查,统计分析黑热病累计发病人群特征。结果 1990年以来该地区人源型黑热病的累积发病率为6.44%(310/4810)。不同性别、文化程度和职业人群间发病差异无统计学意义;不同年龄人群发病差异有统计学意义(P<0.01),随着年龄的增加,发病率逐渐下降。结论喀什地区为黑热病流行较为严重的地区,低年龄组人群仍是防治的重点人群。
