讨论根据本次暴发病例的自觉症状、阳性体征、粪便检查,需要考虑经口传播的急性肠道传染病。按发病曲线特点和可疑食物分析,提示由同一污染包馅引起的可能性较大。食后发病最短潜伏期仅10小时,大多数病例出现在1～3天内,其中又以第一天发病最多,随后渐少。临床表现均以胃肠道和全身症状为主,因此这样的暴发具备了细菌性食物中毒的特点。调查分析节日主副食,虽烧鲳鱼、炒剩饭已变味,有引起食物中毒的可能,但流行病学调查结果并不支持。在就餐人员中吃这两种食物和未吃这两种食物者均有发病,且发病率近似。因此,这两种食物与本次发病无关。
Discussion According to the symptoms of this outbreak, positive signs, stool examination, need to consider the oral transmission of acute intestinal infectious diseases. According to the characteristics of the onset curve and suspicious food analysis, suggesting that the same pollution caused by stuffing is more likely. The shortest incubation period after eating only 10 hours, most cases occur in 1 to 3 days, of which the most incidence of the first day, then gradually less. Clinical manifestations are mainly gastrointestinal and systemic symptoms, so this outbreak with the characteristics of bacterial food poisoning. Investigation and analysis of the main holiday staple food, although burning bonito, fried leftovers have become tasteless, there may be caused by food poisoning, but the epidemiological findings do not support. In the dining staff to eat these two kinds of food and eat these two kinds of food are the incidence, and the incidence rate is similar. Therefore, these two foods have nothing to do with the incidence.
