Abstract:

Objective To understand the epidemiological characteristics of Japanese encephalitis(JE) in Baoshan city from 2005 to 2008 in order to provide a scientific basis for the control and prevention of the epidemic. Methods Descriptive epidemiological analysis was performed on the cases of JE reported in the area from 2005 to 2008. Results A total of 224 JE cases were reported in Baoshan city, 2005-2008, with the annual incidence being 1.70/105, 2.68/105, 2.46/105, 2.35/105, respectively in the years in sequence. It was seen that the incidence was highly sporadic in the individual years, with the peak incidence occuring from July to August, accounting for 63.84% of the total incidence. Children under the age of 10 were most frequently affected, constituting 76.79% of the total cases. There were 3 cases who died of the epidemic with a mortality of 1.34%. Conclusion The epidemic of JE was well under control in Baoshan city, but it is still needed to take comprehensive measures based on vaccination and mosquito control and prevention to make it better.
