【摘要】 目的分析江西省钩端螺旋体病的流行状况,为钩端螺旋体病防治提供科学依据。方法采用描述流行病学方法对江西省2001-2008年钩端螺旋体病疫情资料和监测资料进行流行病学分析。结果2001-2008年全省共报告钩端螺旋体病病例1 405例,年报告发病率在0.11/10万~1.15/10万,年均发病率为0.42/10万;共报告钩端螺旋体病死亡病例38例,病死率为2.75%,病例以散发为主;病例主要发生在江西省的赣州市、宜春市和上饶市,3市病例占全省总病例数的74.59%;7-8月为钩体病发病高峰,占总病例数的71.96%;职业以农民为主,占总病例数的76.44%;发病年龄集中在10~59岁,占全部病例的91.74%;男女性别之比约为2∶1;2002-2007年钩体病监测发现流行菌群为黄疸出血群(32.61%)和澳洲群(15.94%)。结论2001-2008年江西省钩体病发病率呈逐年下降趋势,但部分地区发病率仍较高,7-8月为高发季节,与早晚季水稻"双抢"有关,也与职业人群相符,表现为稻田型流行特征;主要传染源及流行菌群分别为野外鼠和黄疸出血群钩体。更多还原
