上海市青浦区一起本地登革热聚集性疫情调查分析
Epidemiological investigation and analysis of a local dengue fever cluster outbreak in Qingpu District of Shanghai
摘要
Abstract
[Objective]To analyze the epidemiological characteristics of a local dengue fever cluster outbreak in Qingpu District of Shanghai in 2024,and to provide a reference for subsequent dengue fever prevention and control.[Methods]Seven confirmed local dengue fever cases reported through the National Notifiable Infectious Diseases Surveillance System in Qingpu District of Shanghai in 2024 were selected as the research subjects.Descriptive epidemiological methods were used to conduct investigation and analysis from the aspects of onset,medical treatment and reporting,clinical symptoms,travel and contact history within 15 days before onset,and activity trajectories.[Results]A total of 7 cases were identified in this outbreak.None of the cases had a travel history to dengue-endemic areas within 15 days prior to onset,while all had shared exposure environments and mosquito bite histories,indicating a local clustered transmission pattern.The main clinical manifestations included fever(100.00%)and myalgia(42.86%).All 7 cases were positive for dengue virus serotype 2(DENV-2)by nucleic acid testing.Genetic sequencing showed that the virus strains belonged to the Cosmopolitan genotype and were most closely related to the epidemic DENV strains circulating in southern China in recent years.[Conclusion]This outbreak might be a local secondary infection caused by the short-term stay of dengue fever-infected individuals,and the possible source of importation was dengue fever endemic areas in southern China.关键词
