摘要:

目的 分析重庆市5岁及以下儿童其他感染性腹泻流行病学特征,为儿童其他感染性腹泻的科学防控提供依据。方法 利用中国疾病预防控制信息系统收集2017—2023年重庆市5岁及以下儿童其他感染性腹泻病例资料,采用描述流行病学方法对其他感染性腹泻的流行强度、三间分布、病原学特征等进行分析;采用趋势χ2检验分析各年份报告发病率的变化趋势。结果 2017—2023年重庆市累计报告5岁及以下儿童其他感染性腹泻病例213 267例,年均报告发病率为1 589.68/10万,年报告发病率为1 105.47/10万~1 820.54/10万。发病高峰在12月—次年3月,共报告108 026例,占总报告病例数的50.65%。男童和女童报告发病率分别为1 716.38/10万和1 451.14/10万;<1岁年龄组报告发病率最高,为4 546.50/10万;全市不同区(县)间报告发病水平差异较大,报告发病率前三的区(县)分别为沙坪坝区(4 763.75/10万)、巴南区(3 886.36/10万)、南岸区(3 766.21/10万)。共有35 522例5岁及以下儿童病例明确病原体类型,占5岁及以下儿童总病例数的16.66%(35 522/213 267),轮状病毒感染病例占明确病原体类型病例的78.14%(27 758/35 522)。结论 重庆市5岁及以下儿童其他感染性腹泻发病率总体呈较高水平,发病水平在不同地区、季节和人群中差异明显,确诊病例以轮状病毒感染为主。应继续加强对重庆市儿童其他感染性腹泻的监测和防控。

Abstract:

Objective To analyze the epidemiological characteristics of other infectious diarrhea in children aged 5 years and below in Chongqing Municipality for scientific evidences in formulating prevention and control of other infectious diarrhea in children. Methods The case data of other infectious diarrhea in children at age 5 years and younger reported in Chongqing from 2017 to 2023 were retrieved through the Chinese Disease Prevention and Control Information System. Descriptive epidemiological methods were used to analyze the epidemic intensity, distribution characteristics in different region, population and time as well as etiology of other infectious diarrhea. The trend of the reported incidence in each year was analyzed by trend χ2 test. Results A total of 213 267 cases of other infectious diarrhea were reported in children aged 5 and below in Chongqing from 2017 to 2023. The average annual incidence was 1 589.68/100 000, and the annually reported incidence ranged from 1 105.47/100 000 to 1 820.54/100 000. The prevalence peaked between December and March of following year, during which a total of 108 026 cases were reported, accounting for 50.65% of the total reported cases. The reported incidence was 1 716.38/100 000 for boys and 1 451.14/100 000 for girls. The highest incidence (4 546.50/100 000) was found in children aged <1 year. The reported prevalence differed a lot among different districts (counties) within the city, with the top three being Shapingba District (4 763.75/100 000), Ba′nan District (3 886.36/100 000) and Nan′an District (3 766.21/100 000). The pathogen types were clearly identified in 35 522 children aged 5 and below, which accounted for 16.66% (35 522/213 267) of the total cases in this age group. Among the cases with confirmed pathogen types, 78.14% (27 758/35 522) was associated with rotavirus infection. Conclusion The incidence of other infectious diarrhea in children aged 5 and below in Chongqing was generally high, and the prevalence varied significantly in different regions, seasons and age group. The confirmed cases were mainly involved in rotavirus infection. Our findings suggest that surveillance, prevention and control of other infectious diarrhea in children should continue to be strengthened in Chongqing Municipality.
