目的分析红塔区伤寒和甲型副伤寒流行特征和趋势,为今后防制工作提供科学依据。方法采用描述性流行病学方法,对红塔区1998-2007年期间疾病监测信息报告管理系统报告的伤寒和甲型副伤寒疫情资料进行分析。结果2000年后伤寒和甲型副伤寒年度总发病率均超过100/10万,疫情呈快速上升趋势,且间隔2～3年出现高强度的流行;流行季节集中出现在5～10月之间;坝区乡镇发病高于山区乡镇;发病职业以农民、学生、工人、干部职员和教师为主(近80%);发病以10～50岁年龄组为主(85%以上);病原菌以甲型副伤寒沙门菌为主,发病危险因素与食用生冷食物有关。结论红塔区2000年后属于甲型副伤寒高流行区,流行因素主要与本地居民饮食习惯有关,加强传染源的管理及饮食行为干预和生冷食物的监测,是控制当前红塔区伤寒流行的主要措施。
