[目的]掌握上海市黄浦区沙门菌感染的流行病学特征。[方法]随机抽取3家区监测点医院开展腹泻病人监测,对符合沙门菌监测对象定义的病例记录其临床表现、流行病学史,并留便进行血清学检测。[结果]2008—2011年黄浦区腹泻病例中沙门菌检出率呈现下降趋势,检出率平均为3.25%,略高于本市平均水平(3.13%)。沙门菌感染以5—10月为多,男性发病率是女性的1.53倍,高发年龄为20～39岁,血清分型以肠炎沙门菌(31.83%)和鼠伤寒沙门菌(15.57%)为优势菌种。[结论]黄浦区腹泻病例中沙门菌检出率呈下降趋势,但沙门菌平均检出率高于上海市平均水平,应引起重视,加强预防控制。除做好病例监测和管理工作外,还需加强食品卫生和安全管理的宣传教育,提高人群的卫生防病意识。
[Objective] To master the epidemiological characteristics of Salmonella infection in Huangpu District of Shanghai. [Method] The hospital of 3 district monitoring sites was randomly selected to carry out the monitoring of patients with diarrhea. The clinical manifestations, epidemiological history of the patients meeting the definition of the target of Salmonella surveillance were recorded and serological tests were carried out. [Results] The detection rate of Salmonella in diarrhea cases of Huangpu District showed a decreasing trend from 2008 to 2011, with an average detection rate of 3.25%, slightly higher than the city average (3.13%). Salmonella infection is more in May-October, the incidence of males is 1.53 times that of females, the highest incidence of 20 to 39 years of age, serotypes of Salmonella enteritidis (31.83%) and Salmonella typhimurium (15.57%) advantage Species. [Conclusion] The detection rate of Salmonella in diarrhea cases in Huangpu District showed a decreasing trend, but the average detection rate of Salmonella was higher than the average level in Shanghai, so attention should be paid to prevention and control. In addition to doing a good job in case monitoring and management, we need to step up publicity and education on food hygiene and safety management so as to raise public awareness of health and disease prevention.
