摘　　要：目的了解2010-2020年云南省伤寒与副伤寒流行特征,为制定有效防控措施提供科学依据。方法对云南省11年的伤寒副伤寒疫情资料进行描述性分析。结果 2010-2020年全省共报告伤寒副伤寒病例35 217例,死亡6例,年均发病率6.79/10万,总病死率0.017%;2010-2020年报告病例数、发病率总体呈现下降趋势。云南省伤寒副伤寒全年均有病例报告,主要发病于5-10月,占总病例数的60.75%;发病地区分布广泛,其中西双版纳州年平均发病率为全省最高(20.04/10万);以10岁为等组距,20~岁年龄组累计发病数最多,占总病例数的18.14%;男女性发病数之比为1∶1;发病人数最多的职业是农民(47.04%),其次为学生和学龄前儿童。结论云南省11年来伤寒副伤寒发病总体呈下降趋势,应针对重点区域、重点人群和高发季节采取有效防控措施。Objective To analyze the epidemic characteristics of typhoid and paratyphoid fever in Yunnan from 2010 to 2020,and to provide scientific basis for the formulation of effective prevention and control measures.Methods Based on the epidemic data of typhoid and paratyphoid fever in Yunnan Province in the past 11 years,the epidemic situation was descriptively analyzed.Results A total of 35217 cases of typhoid and paratyphoid fever and 6 deaths were reported in the province from 2010 to 2020,with an average annual incidence rate of 6.79/100000 and a total fatality rate of 0.017%.The number of reported cases and incidence showed an overall downward trend from 2010 to 2020.Cases of typhoid and paratyphoid fever in Yunnan Province were reported throughout the year,which mainly occurred from May to October,accounting for 60.75%of the total number of cases.The incidence was widely distributed in a wide range of areas,of which the average annual incidence in Xishuangbanna was the highest in the province(20.04/100000).With 10 years old as the equal group distance,the 20-year-old age group had the largest cumulative number of cases,accounting for 18.14%of the total number of cases;the ratio of male to female was 1;the occupation with the largest number of cases was farmers(47.04%),followed by students and scattered children.Conclusion The incidence of typhoid and paratyphoid fever has shown an overall downward trend in Yunnan Province in the past 11 years,and effective prevention and control measures should be taken for key areas,key populations and high incidence seasons.
