摘要
目的:探讨四川省巴中地区手足口病流行特征和病原分布情况。方法:收集2016年1月至2017年12月巴中市手足口病例数据进行描述流行病学分析。结果:2016-2017年,全市累计报告手足口病3102例,其中临床诊断病例2843例,确诊病例259例;重症病例56例,占病例总数的1.86%,无死亡病例。2017年发病率较2016年有明显上升(P<0.05);男女发病率比较差异无统计学意义(P>0.05);年龄分布,以1~3岁组儿童为主,2016年和2017年分别占50.42%和43.95%;2016年和2017年儿童职业分布差异比较无统计学意义(P>0.05),散居儿童比例分别为55.49%和54.43%;手足口病发病有两个高峰,即每年5月份和11月份;2016年和2017年病原分布差异有统计学意义(P<0.05),其中2016年、2017年EV71比例分别为42.20%和13.33%;2016年和2017年重症患者病原分布差异比较无统计学意义(P>0.05)。结论:巴中市手足口病发病呈现明显的季节、职业和年龄分布特征,病原体EV71的比例有所降低。
Objective: To investigate the epidemic characteristics and pathogen distribution of hand-foot-mouth disease(HFMD) in Bazhong district of Sichuan province.Methods: Descriptive epidemiological analysis was conducted on HFMD data in Bazhong district from January 2016 to December 2017.Results: From 2016 to 2017,3102 cases of HFMD were reported in the city,including 2843 cases of clinical diagnosis and 259 cases of confirmed cases;56 severe cases accounted for 1.86% of the total number of cases,no deaths.The incidence rate in 2017 was significantly higher than that in 2016(P<0.05).There was no significant difference in the incidence rate between male and female(P>0.05).The age distribution was mainly children aged one to three years,accounting for 50.42% and 43.95% in 2016 and 2017,respectively.In 2016 and 2017,there was no significant difference in the occupational distribution of children(P>0.05),and the proportion of scattered children was 55.49% and 54.43%,respectively.There were two peaks of HFMD,that was.May and November each year.The differences in the distribution of pathogens in 2016 and 2017 were statistically significant(P<0.05),and the proportion of EV71 in 2016 and 2017 were 42.20% and 13.33%,respectively.There was no significant difference in the distribution of pathogens in severe patients in 2016 and 2017(P>0.05).Conclusion: The incidence rate of HFMD in Bazhong district has obvious seasonal,occupational and age distribution,and the proportion of pathogen EV71 has decreased.
