Analysis on the pathogenic features and epidemiological trend of mosquito-borne diseases in Wenzhou City

Objective The study was conducted to analyze the pathogenic features and epidemiological trend of mosquito-borne diseases from 1950 to 2005 in Wenzhou City so as to provide a scientific basis for the adoption of prevention and control measures. Methods The epidemiological data in these 56 years were statistically analyzed. Results From the year 1950 to 2005, a total of 127 067 cases of malaria were reported in Wenzhou City with the average annual incidence rate of 40.26/lakh; 17 311 cases of JE (Japanese encephalitis) with the average annual incidence rate of 5.69/lakh. The total incidence rate of the two diseases declined and there were no evident pathogenic cycles. The incidence of JE was obviously seasonally distributed with the peak period of July and August, which was consistent with the results of mosquito-borne monitoring (mosquito anatomy test); the incidence of malaria was also seasonally distributed. And 5 cases of dengue fever were reported and both were imported cases. Conclusion There are epidemiological risk factors of mosquito-borne diseases in Wenzhou City, and systemic preventive measures should be taken to control the epidemic and the spread of mosquito-borne diseases.
