摘要
目的对临沂市1956—2011年伤寒副伤寒进行流行病学分析,制定科学控制对策,消除流行周期。方法收集该市1956—2011年伤寒副伤寒疫情及流行病学个案调查资料,采用总和统计和年代统计的方法进行流行病学分析。结果 1956—2011年共计发生伤寒副伤寒12 079例,年均发病率为2.45/10万。发病具有20 a左右1次的流行周期,每年6—12月份为多发季节。年龄主要集中在15～40岁,占77.72%;农民、学生、工人发病占81.75%,平原发病高于山区。目前该地区已进入第3次流行周期后的散发期,2005—2011年年均发病率已降为0.78/10万。结论控制传染源,切断传播途径,进一步净化疫情,该市20年左右1次的伤寒副伤寒流行周期可被消除。
[ Objective ] To analyze the epidemiological characteristics of typhoid fever and paratyphoid fever, make the scientific control countermeasures, so as to eliminate the epidemic periodicity. [ Methods ] The data of epidemic situation and individual cases of typhoid fever and paratyphoid fever from 1956 to 2011 in Linyi City were collected, and the epidemiological analysis was conduc- ted by total statistics and time statistics.
