摘　　要：目的:了解某驻训部队一起感染性腹泻暴发的特点和流行原因,探讨暴发疫情处理的经验并为制定防控措施提供依据。方法:采用现场流行病学调查分析和实验室检测方法。结果:2018年6月14日~6月25日,某驻训部队陆续出现腹泻病人,45例,其中干部5人,战士40人。病例的临床表现基本相同,以发热、腹泻、腹痛、乏力等症状为主,病程3~5天。回顾性队列研究显示,生饮附近村庄小商店贩卖无商标桶装水为主要危险因素,从患者肛拭子标本中和桶装水中检测到诺如病毒抗原,采取禁止饮用该桶装水、隔离治疗患者和健康教育等综合措施后,疫情得到有效控制。结论:本次疫情为一起诺如病毒感染性腹泻暴发,暴发原因是饮水不洁造成的,为部队今后野外驻训期间的胃肠道传染病防控提供了经验参考。Objective: To understand the characteristics and causes of an outbreak of infectious diarrhea in a military unit in training, discuss the experience in dealing with the outbreak and provide basis for the formulation of prevention and control measures. Methods: Field epidemiological investigation and laboratory testing were used. Results: From June 14, 2018 to June 25, 2018, 45 cases of diarrhea occurred in a certain troop, including 5 cadres and 40 soldiers. The clinical manifestations of the cases were basically the same, with fever, diarrhea, abdominal pain, fatigue and other symptoms as the main symptoms, and the course of the disease was 3 to 5 days. Retrospective cohort study showed that selling unbranded bottled water in small shops in nearby villages was the main risk factor. Norovirus antigen was detected from patients’ anal swabs and bottled water, and the epidemic situation was effectively controlled after comprehensive measures, such as prohibition of drinking the bottled water, isolation and treatment of patients, and health education. Conclusion: This outbreak is an outbreak of norovirus infectious diarrhea, which is caused by unclean drinking water. It provides an empirical reference for the prevention and control of gastrointestinal infectious diseases during field training in the future.
