摘要
目的了解杭州市食源性疾病的流行病学特征,为疾病防控提供科学依据。方法收集2012—2020年在杭州市60家食源性疾病监测医院就诊的食源性疾病病例信息,并进行流行病学特征和病原学分析。结果2012—2020年杭州市共上报食源性疾病病例54479例,以5~10月较为集中,占总报告病例数的67.83%(36954/54479);26~35岁和≤5岁年龄组为高发病年龄组,分别占21.78%(11865/54479)和17.08%(9307/54479);病例职业以农民最多,其次为干部职员和托幼儿童。采集食源性疾病病例生物标本41905份,共检出病原体3380株,其中诺如病毒检出率最高,为8.77%(734/8370),其次为副溶血性弧菌2.68%(1097/40914)、致泻性大肠埃希菌2.39%(527/22012)、沙门菌2.38%(978/41052)、志贺菌0.11%(44/41046)。诺如病毒的检出高峰为3月和11月,副溶血性弧菌为8月。结论杭州市食源性疾病病例具有明显的季节性和人群分布特征,应加强对食源性病原体的监测和可疑食物暴露调查,为开展有效防控提供技术支持。
Objective To provide scientific evidence for disease prevention and control,the epidemiological characteristics of foodborne disease in Hangzhou City were studied.Methods Data on foodborne diseases in 60 surveillance hospitals in Hangzhou were collected from 2012 to 2020.Epidemiological and pathogenic characteristics of these surveillance data were analyzed.Results A total of 54479 cases of foodborne disease were reported in Hangzhou from 2012 to 2020,and most cases(67.83%,36954/54479)appeared from May to October.Adults 26 to 35 years old(21.78%,11865/54479)and children≤5 years old(17.08%,9307/54479)were more vulnerable to foodborne disease.Among different occupational groups,the proportion of farmers was the highest,followed by official staff and nursery children.A total of 41905 samples were collected,and 3380 strains of pathogens were isolated.The positive rate of Norovirus was the highest(8.77%,734/8370),followed by Vibrio parahaemolyticus(2.68%,1097/40914),Diarrheogenic Escherichia.coli(2.39%,527/22012),Salmonella(2.38%,978/41052),and Shigella(0.11%,44/41046).The Norovirus positive rate peak was observed in March and November,whereas that of Vibrio parahaemolyticus was in August.Conclusion The incidence of foodborne diseases in Hangzhou City has noticeable seasonal and population distribution characteristics.The monitoring of foodborne pathogens and the suspicious food investigation of foodborne disease cases should be strengthened to provide technical support for effective prevention and control.
