摘要:

目的 描述2011—2021年成都市其他感染性腹泻的流行特征并分析时空聚集性,为肠道传染病防控提供科学依据。方法 通过中国疾病预防控制信息系统传染病监测系统,收集成都市2011—2021年其他感染性腹泻数据,描述发病概况及三间分布特征,并采用空间自相关分析及时空扫描分析探索其时空聚集性特征。结果 2011—2021年成都市累计报告其他感染性腹泻例94 955例,年均报告发病率为53.46/10万,年报告发病率为36.86/10万~78.64/10万,总体呈上升趋势(χ2趋势=34.13,P<0.001)。报告病例数总体上存在夏季和冬季2个高峰。报告病例中,男性52 125例,女性42 830例,性别比为1.22∶1;年龄分布上,6岁以下年龄组占比最高,为74.00%(70 268/94 955);职业分布上,散居儿童占比最高,为67.21%(63 821/94 955)。全局空间自相关分析显示2011—2019年感染性腹泻存在空间聚集性,局部空间自相关分析发现高新区、青羊区、成华区、武侯区、锦江区和金牛区等是发病的“热点”区域,邛崃市、蒲江县和大邑县则为“冷点”区域。时空扫描分析同样显示成都市感染性腹泻存在明显的时空聚集性,主集群除涉及高新区、青羊区、成华区、武侯区、锦江区和金牛区外,还涉及青白江区、金堂县、崇州市、新津区、天府新区等区域,聚集时间多为夏季和冬季。结论 近年来,成都市其他感染性腹泻报告发病总体呈上升趋势,发病高峰主要在夏季和冬季,报告病例主要为6岁以下散居儿童,建议在高发季节对重点地区、重点人群加强监测和健康教育等防控工作。

Abstract:

Objective To describe the epidemic characteristics of other infectious diarrhea in Chengdu area from 2011 to 2021, and analyze the temporal and spatial aggregation so as to provide scientific basis for prevention and control of these intestinal infectious diseases. Methods The data of other infectious diarrhea diseases reported in Chengdu area were retrieved through the Infectious Disease Surveillance System under the Chinese Disease Prevention and Control Information System from 2011 to 2021. The incidence profile and the distribution characteristics in different region, population and time were described. The spatial autocorrelation analysis and spatial and temporal scanning were used to analyze the characteristics of spatial and temporal aggregation. Results A total of 94 955 cases of other infectious diarrhea were reported with an average annual incidence of 53.46/100 000 in Chengdu area from 2011 to 2021. The annual reported incidence was 36.86/100 000-78.64/100 000, showing an overall upward trend (χ2Trend=34.13, P<0.001). The highest number of reported cases was mainly seen in summer and winter. In the reported cases, 52 125 were males, and 42 830 females, with a sex ratio being 1.22∶1. By age distribution, incidence of the infections was the highest in children under 6 years old (74.00%, 70 268/94 955). By occupational distribution, the proportion of scattered children was the largest (67.21%, 63 821/94 955). Global spatial autocorrelation analysis showed that there was spatial clustering of other infectious diarrhea during 2011 to 2019. Local spatial autocorrelation analysis found that the Hi-tech Zone, Qingyang District, Chenghua District, Wuhou District, Jinjiang District and Jinniu District were the "hot spots" of the disease, while Qionglai City, Pujiang County and Dayi County were the "cold spots". Spatial-temporal scanning analysis also shows that there is obvious spatial-temporal clustering. In addition to the Hi-tech Zone, Qingyang District, Chenghua District, Wuhou District, Jinjiang District and Jinniu District, the main cluster also involves Qingbaijiang District, Jintang County, Chongzhou City, Xinjin District, Tianfu New District and other areas. The clustering time is mostly summer and winter. Conclusion In recent years, prevalence of other infectious diarrhea in Chengdu represents an overall upward trend, and primarily peaks in summer and winter. The reported cases are mainly scattered children under 6 years old. These findings suggest that monitoring of key areas and key populations as well as health education should be strengthened during the prevalent season.
