[Epidemiological characteristics of Japanese encephalitis in Shanghai].
Objectives: To understand the epidemiological characteristics of Japanese Encephalitis in Shanghai and to provide evidence for preventing JE.
Methods: Epidemic characteristics, JEV antibody in healthy population and swine infection rate in Shanghai were analyzed by methods of field survey, serology and molecular biology.
Results: JE incident rate in Shanghai was 0.077/100,000 in 2006; and 0.129/100,000 in 2007. Antibody positive rate before JE epidemic fastigium was 60.39%; postive rate after epidemic was 85.44%. JE IgG positive rate was 26.92% in 3-month swine and 14.86% in swine for sale; JE Gene in mosquito was analyzed for type 1.
Conclusion: The JE prevalence rate is relatively low in Shanghai. JE antibody positive rate is high in Shanghai population. Swine as a media is infected by JE virus. The JE virus in mosquitoes belongs to genotype 1.
