【摘要】 报告了江苏省如东、吴县和宝应三县（市）伤寒监测点伤寒流行特征及监测的研究。结果显示：三县（市）是我省伤寒的高发地区，1996年伤寒总病例数为701例，占全省总数的8．87％，年均发病率为23．05／10万，显著高于全省平均发病率（11．46／10万）。发病率以5～9a年龄组最高，发病数以青壮年的农民为最多。通过对144例伤寒病人的流行因素调查，病例组的不洁食物史的暴露率明显高于对照组（分别为71．53％和34.03％），OR为7．75，说明我省伤寒的传播途径有从原来的水型传播为主向食物型传播转变的趋势。沿海地区的如东县发病高峰为5月份，早于其它二县（市）3个月，对100例病人配对调查结果分析，可能与生吃海产品有关。更多还原

【Abstract】 The study of epidemic features of typhoid fever was made in Rudong, Wuxian and Baoying county. The results showed that the three counties were typhoid fever endemic areas.Total number of the cases in these areas was 701, which accounted for 8. 87% of the whole cases in Jiangsu Province. Annual incidences (23. O5/100, 000) in these counties were much higher than that in whole province (11. 46/100, 000). The incidence in the age of 5～9 old was the highest. The epidemic factors of 144 patients were analysed. The rate of eating contaminated food in case group (71. 35 % ) was higher than that in control group (34.03% ). OR was 7. 75.It indicated that the trend of transmitted route was from waterborne type to foodborne type. The peak in Rudong was in May. It was 3-months earlier than that in other two counties. 100 patients in Rudong were analysed. The results demonstrated that it might be caused by eating raw sea food.更多还原
