辽宁省2014—2019年副溶血性弧菌感染状况及其流行病学特征分析

Epidemiological characteristics of Vibrio parahaemolyticus infection in foodborne diseases in Liaoning from 2014 to 2019

目的了解辽宁省副溶血性弧菌感染的发病状况和流行病学特征,为科学制定预防和控制措施提供依据。方法收集2014—2019年辽宁省副溶血性弧菌感染者的病例信息,通过对其生物样本进行实验室检测,使用SPSS 17.0软件进行统计分析,采用Mantel-Haenszel分层分析方法计算不同性别、年龄、职业、地域的副溶血性弧菌检测情况的OR值及95%CI。结果 2014—2019年辽宁省食源性疾病副溶血性弧菌检出率为4.37%。副溶血性弧菌检出率存在地域间(沿海地区为5.59%和非沿海地区为2.86%,χ^(2)=87.627,P<0.01)、年龄间(χ^(2)=122.612,P<0.01)和职业间(χ^(2)=139.107,P<0.01)差别。867例副溶血性弧菌阳性病例中,25~44岁年龄组占比43.37%(376/867);发病时间以第三季度为主,7、8月份高发;可疑暴露食品以水产动物及其制品、肉及肉制品为主,分别占比52.14%(390/748)、12.97%(97/748)。结论副溶血性弧菌是辽宁省食源性疾病散发病例的重要病原体之一。

Objective To analyze the incidence and epidemiological characteristics of Vibrio parahaemolyticus infection in Liaoning Province, and to provide scientific basis for prevention and control measures.Methods The case information of Vibrio parahaemolyticus infection in Liaoning from 2014 to 2019 was collected, and the stool samples of patients were collected for detection. SPSS 17.0 software was used for statistical analysis. The Mantel-Haenszel was used to calculate the OR and 95%CI of different sex, age, occupation and regions. Results Detection rate of Vibrio parahaemolyticus was 4.37% from 2014 to 2019 in Liaoning Province. There were significant differences in the patients of Vibrio parahaemolyticus among different regions(5.59% and 2.86%, χ^(2)= 87.627, P<0.01), age(χ^(2)=122.612, P<0.01) and occupations(χ^(2) =139.107, P<0.01). 376 cases were between 25 and 44 years old with the proportion of 43.37%(376/867). There were obvious seasonal characteristics, and the peak time of detection rate was in summer. Main exposed food were aquatic animals and their products(52.14%, 390/748), meat and their products(12.97%, 97/748).Conclusion Vibrio parahaemolyticus is one of the important pathogens of foodborne diseases in Liaoning Province.
