目的 探讨1998年洪灾对江西省传染病流行的影响及相关的因素。方法 对江西省洪灾前后的传染病疫情及部分灾区流行的疾病个案进行分析。结果 1997～1999年江西省甲、乙类传染病的发病率分别为198．19／10万、224．68／10万及253．22／10万，1993～1997年平均发病率为187．68／10万。1998年与1997年、1993～1997年的平均水平相比，甲、乙类传染病的总发病率分别上升了13．37％和19.71％，其中以霍乱、出血热和钩端螺旋体病上升最为明显；1999年与1997年、1998年相比，分别上升了27．77％和12．70％，其中以霍乱、甲肝上升最为明显。1998年受灾县与非受灾县、全省和全国比，肠道传染病和自然疫源性疾病上升较明显；灾后第二年，除了肠道传染病继续上升外，呼吸道传染病的上升也较明显。结论 1998年洪灾对江西省传染病的流行产生了一定的影响，部分受灾县传染病的发病有不同程度的上升。
