摘要:

目的 分析昆明市其他感染性腹泻流行规律和特征,为采取针对性防控措施以及调整防控策略提供参考。方法 通过中国疾病预防控制信息系统收集昆明市2017—2021年其他感染性腹泻的病例报告信息及突发公共卫生事件资料,对其三间分布特征及病原学分类进行统计描述。结果 2017—2021年昆明市共报告其他感染性腹泻病例58 909例,无死亡病例,年均报告发病率为156.90/10万,年报告发病率为123.66/10万~194.03/10万。报告病例数存在季节性高峰,主要发生在冬季(12月—次年1月)。年均报告发病率前5位的地区为安宁市(226.65/10万)、五华区(210.63/10万)、晋宁区(185.68/10万)、石林县(180.08/10万)和盘龙区(174.33/10万)。报告病例中男性31 559例(占53.57%),女性27 350例(占46.43%);各年龄段人群中,5岁以下人群报告病例数占比最高,为68.02%(40 067/58 909);不同职业中,散居儿童报告病例数占比最高,为65.47%(38 566/58 909)。明确病原体的报告病例中,病毒性腹泻病例占比最高,为99.38%(10 205 /10 269),其中以轮状病毒感染的病例居多,占94.06%(9 659/10 269)。2017—2021年,全市共报告其他感染性腹泻事件8起,总罹患率为0.86%,其中7起发生在学校和托幼机构;7起病原体明确的事件中,由诺如病毒引起的事件有6起。结论 其他感染性腹泻防控是昆明市传染病防控工作中的重要内容之一,建议在流行季节前开展儿童轮状病毒疫苗接种,高峰期应加强重点地区(机构)的疫情监测和控制工作。

Abstract:

Objective To analyze the epidemic pattern and characteristics of other infectious diarrhea in Kunming area, and propose targeted prevention and control measures according to the epidemic regularity and characteristics, so as to provide theoretical support for adjusting prevention and control strategies by the health administration sections. Methods The data on the reported cases of other infectious diarrhea and public health emergencies in Kunming were collected through the Chinese Disease Prevention and Control Information System from 2017 to 2021, and described in accordance with the three-distribution and pathogenic classification. Results In total, 58 909 cases of other infectious diarrhea were reported in Kunming area from 2017 through 2021. No deaths were reported. Annual average reported incidence was 156.90/100 000, and annual reported incidence rate was 123.66/100 000-194.03/100 000. The number of reported cases showed seasonal peaks, primarily occurring in winter (December-January). The top 5 areas by average annual reported incidence were Anning City (226.65/100 000), Wuhua District (210.63/100 000), Jinning District (185.68/100 000), Shilin County (180.08/100 000) and Panlong District (174.33/100 000). Of the reported cases, 31 559 were males (53.57%), and 27 350 females (46.43%). By different age group, the population under 5 years of age was the highest in the cases reported, which accounted for 68.02% (40 067/58 909). Among different occupations, the number of cases reported was the highest 65.47% (38 566/58 909) for children of scattered living. The incidence of viral diarrhea was 99.38% (10 205/10 269) in the diseases with clear etiology, in which rotavirus infection accounted for 94.06% (9 659/10 269). Eight other infectious diarrhea events were reported in the city from 2017 to 2021, of which 7 occurred in schools and nurseries. The total attack rate was 0.86%. Of the 7 events with clear etiology, 6 were caused by norovirus. Conclusion The prevention and control of other infectious diarrhea is one of the important tasks in the prevention and control of infectious diseases in Kunming area. Children are recommended to be vaccinated with rotavirus vaccine before the epidemic season, and the epidemic monitoring and control work in key areas and institutions should be strengthened during the peak period.
