Dynamic analysis of tuberculosis infection in Yunnan province

目的 分析云南 1 0年涂阳患病率上升的主要原因。评价控制涂阳肺结核措施的效果 ,为制定肺结核传染源控制规划提供科学依据。方法 采用 1 991～ 2 0 0 0年结防机构中诊治的涂阳肺结核 860 9例 ,新发涂阳病人 7465例及云南 3次结核病流调资料。结果 云南涂阳患病率呈上升趋势 ,1 991年至 2 0 0 0年平均年递增率为 4.8%。男性显著高于女性 (P <0 .0 5 ) ;涂阳病人高峰年龄在 2 5～3 4岁组 ,1 0年累计新发肺结核传染源 7465例 ,仅占应发现数的 1 0 .5 % ,治愈率为 74.3 %。结论 低治愈率、低发现率是导致涂阳患病率上升的主要原因。因此 ,需要加强政府承诺 ,行政干预 。
