摘要
目的 了解2017-2021年柳州市食源性疾病监测情况,分析其流行病学特征,为进一步提高食源性疾病监测能力策略的制订提供科学依据.方法 收集2017-2021年柳州市食源性疾病监测点报告系统中数据,并对采集的粪便/肛拭子标本进行病原体检测,采用描述性流行病学方法进行统计分析.结果 2017-2021 年柳州市共监测病例13 721 例,男性6569例,女性7152例;年龄以0～4岁组病例最多(3490例,25.44%),职业以散居儿童居多(3147例,22.94%);发病高峰期为每年的7-9月(3999例,29.15%);病例的主要暴露食品为水果及其制品(2854例,20.80%),可疑暴露食品的包装方式以散装为主(4309例,31.40%),暴露场所以家庭为主(10 127 例,73.81%).共采集生物标本 3517 份,其中致病菌检出率为11.57%,主要为沙门菌(6.11%),集中在5-10月(80.84%),诺如病毒检出率为8.94%,主要集中在1-3月(3.57%),年龄、职业、季节组内病原体检出率差异有统计学意义(P<0.001).结论 柳州市食源性疾病发病高峰期为7-9月,高危人群为0～4岁儿童,主要暴露场所以家庭为主,相关部门应在高峰期加强对以上高危人群食源性疾病的监测和预防,加强对家庭食品加工安全的宣教;生物标本检测主要检出的病原体为沙门菌和诺如病毒,提示相关部门应加强此类微生物易污染食品的监督监测,做出及时预警和宣传.
Abstract
Objective To understand the surveillance of food-borne disease in Liuzhou City from 2017 to 2021,and to analyze their epidemiological characteristics,so as to provide scientific basis for developing strategies to further improve the surveillance capacity of food-borne diseases.Methods Data from the food-borne disease monitoring point reporting system in Liuzhou City from 2017 to 2021 were collected,and pathogen testing on the collected fecal/anal swab samples was conduc-ted.In addition,statistical analysis was performed by descriptive epidemiological methods.Results From 2017 to 2021,a total of 13 721 cases were monitored in Liuzhou City,with 6569 males and 7152 females;the age group of 0-4 years had the highest number of cases(3490 cases,25.44%),and the majority of occupations were scattered children(3147 cases,22.94%),and the peak period of onset was from July to September each year(3999 cases,29.15%).The main exposed food of the cases was fruits and their products(2854 cases,20.80%),the packaging of suspected exposed food was mainly in bulk(4309 cases,31.40%),and the exposed places were mainly in households(10 127 cases,73.81%).A total of 3517 biological specimens were collected,of which the detection rate of pathogenic bacteria was 11.57%,mainly Salmonella(6.11%),concentrated from May to October(80.84%),and the detection rate of Norovirus was 8.94%,mainly concen-trated from January to March(3.57%).The difference in pathogen detection rates among age,occupation,and seasonal groups was statistically significant(P<0.001).Conclusion The peak period of food-borne diseases in Liuzhou City is from July to September,and the high-risk people are children aged 0 to 4 years,and the exposed places are mainly families.Rele-vant departments should strengthen the monitoring and prevention of food-borne diseases among the above-mentioned high-risk groups during peak periods,and strengthen education on the safety of household food processing.The main pathogens detec-ted in biological specimen testing are Salmonella and Norovirus,indicating that relevant departments should strengthen the supervision and monitoring of food contaminated by such microorganisms,and make timely warnings and publicity.
