Objective To analyze the epidemiological characteristics of the first dengue fever outbreak as well as the density and seasonal fluctuation of Aedes mosquitoes. Methods The reported cases and epidemiological data of dengue fever and mosquito vectors in Yunfu city were analyzed statistically and described. The density of Aedes larvae was monitored by Bretu index method, and that of adult mosquito populations by mosq-ovitrap method. Results There was 22 cases of dengue fever in Yunfu city in 2014, the incidence was 0.91/100 000, including 10 imported case and 12 local cases. Monitoring the mosquito vectors density in 10 sites during July through November in 2014, Aedes Breteau index fluctuated between 3.46-6.58, Mosq-ovitrap average index was 3.39. Conclusion The prevention and control of dengue fever in Yunfu city warrants more attention, low risk does exist for local outbreaks of dengue fever, suggesting to strengthen mosquito-borne disease surveillance, as well as studies on relevant natural and social factors.
