Abstract
Objective To analyze the epidemiological characteristics of dengue fever in Shenzhen from 2013 to 2023 so as to provide the basis for formulating comprehensive prevention and control measures.Method According to the data from the Chinese Disease Prevention and Control Information System and the epidemiological investigation of dengue fever in Shenzhen,Guangdong Province,descriptive epidemiological methods were applied to analyze the distribution characteristics of the cases,the place of infection,the time from onset to diagnosis,the outbreak situation and the results of pathogen surveillance.Result From 2013 to 2023,a total of 1774 cases of dengue fever were reported in Shenzhen,including 955 local cases,564 imported cases from abroad and 255 imported cases from China.2014(454 cases),2019(523 cases)and 2023(386 cases)were the three high incidence years,among which 2014 and 2023 were dominated by local cases,and 2019 was dominated by imported cases.The cases were mainly concentrated from August to November(83.8%).Cases occurred in 10 administrative districts of Shenzhen,covering 94.6%of the total number of streets in the city.The mean age of the patients was 38.2±13.6 years,mainly in the age group of 20-<50 years.The male to female ratio was 1.9 to 1;Most of the cases were workers,domestic workers,unemployed people and business people,accounting for 49.3%(874/1774).Overseas imported cases were mainly from Southeast Asian countries(478/564,84.8%),and domestic imported cases were mainly from the Pearl River Delta region(157/255,61.6%).The median interval between the onset time and diagnosis time of cases was 4.7(2.6,6.8)days,and the interval showed a decreasing trend from 2016 to 2023,especially for local cases.There were 24 local outbreaks,mainly at construction sites(12),with the most occurring in October(11).There were a variety of dengue virus serotypes,and type Ⅰ was the dominant type,accounting for 87.2%(937/1075).Conclusion The risk of dengue epidemic transmission in Shenzhen was high,and the local cases were mainly caused by imported cases.It has obvious spatiotemporal aggregation.关键词
