摘　　要：目的:查明引起甲型副伤寒疫情流行的危险因素,以制定有效防控措施,迅速控制疫情。方法:采用病例对照调查对70例病例及70例对照进行问卷调查,并选择了非暴露于同一水源的另一乡镇进行回顾性队列研究,分别计算OR、RR与PAR%值。结果:单因素分析,"以集中式供水为洗漱用水"、"用水冲洗水果"2项危险因素有统计学意义,回顾性队列研究分析两地水源暴露的相对危险度之比(RR=3.88),PAR%为74.07%。居民使用受致病菌污染的水源是引起疫情的主要因素。结论:加大农村及城郊结合部等地区的改水力度,杜绝此类疫情发生。Objective The present study of the epidemic factors of paratyphoid A Epidemic for the effective prevention and control of the disease.

ResultsThe single-factor analysis showed that＂ using centrally supplied water as washing water＂ ,＂rinsing fruits with centrally supplied water＂ have statistically significant difference. The RR between exposed and non-exposure groups was 3. 88, and the Attributable Risk of water exposure was 74. 07%.
