1991年7月对河南洪水特重灾新蔡县三个不同程度受灾村840名灾民进行了灾后两个月疫情调查,非痢疾性腹泻罹患率为35.7％、痢疾9％、红眼病5.7％、皮肤病5.4％、肝炎和乙脑均为0.1％,无死亡病例。轻灾村痢疾罹患率(16.2％)最高,并有家庭聚集性,而重灾村非痢疾性腹泻(42.2％)和皮肤病(7.8％)最高(p<0.01)。三村非痢疾性腹泻和痢疾家庭续发率均为25％。非痢疾性腹泻续发率:罹患率为2.8:1,痢疾为10.9:1。各疾病罹患率的高低同灾情无平行关系,但腹泻病伴中重度脱水者以中灾村和重灾村最明显,75％的腹泻病患者患脱水。食用霉变小麦的灾民占98.5％,是非痢疾性腹泻发病的重要危险因素(RR=5.07,p<0.05)。小口井痢疾罹患专率最高(20.1％),依次为大口井(16.2％)、压水井(5.4％)和河水专率(2.1％)(p<0.0001)。腹泻病发病时间分布不呈正态分布,重灾村呈上升趋势。发病高峰在0—5岁组,并随年龄增加而下降(r=-0.71,p<0.01)
In July 1991, an investigation was conducted on the epidemic situation of 840 victims in three disastrous villages in Xinzai County of Henan Province, a special flood disaster in Henan Province. The incidence of non-diarrhea diarrhea was 35.7%, dysentery 9%, pink eye disease 5.7% Disease 5.4%, hepatitis and JE were 0.1%, no deaths. The incidence of dysentery in the disaster-stricken area was the highest (16.2%) with familial agglomeration, with the highest incidence of non-diarrheal diarrhea (42.2%) and dermatosis (7.8%) in the severely affected villages (p <0.01). Three villages with non-diarrhea diarrhea and diarrhea families with recurrence rates were 25%. The incidence of non-diarrheal diarrhea continued: the attack rate was 2.8: 1, dysentery was 10.9: 1. The prevalence of each disease has no parallel with the disaster, but diarrhea with moderate to severe dehydration in the disaster village and severely affected villages most obvious, 75% of patients suffering from diarrhea dehydration. 98.5% of the victims of mildew consumption are important risk factors for the development of non-diarrheal diarrhea (RR = 5.07, p <0.05). The highest specific incidence of dysentery dysentery (20.1%) was followed by large wells (16.2%), pressurized wells (5.4%) and river water specifics (2.1%) (p <0.0001). The incidence of diarrheal disease distribution is not normal distribution, heavy disaster village is on the rise. The peak incidence in the 0-5 age group, and decreased with increasing age (r = -0.71, p <0.01)
