In 1980, Dengue was found on Dailu Street in Hepu, Hepu, Qinzhou and Shabu, Qinzhou. Dengue was not found any more in Guangxi within five years from 1981 to 1985; however, JE was scattered. In order to understand the changes of dengue antibody level in a population after dengue fever epidemic, as well as the trend of encephalitis antibody and dengue virus infection associated with dengue antigen, we conducted three specific serological tests in residents of Shatian and Dalu from 1982 to 1985 Testing, Dengue antibody in the study of the dynamic at the same time, have found a diagnostic titer of the West Nile positive antibodies, the latter has not been reported in the country. The monitoring results are reported as follows.Materials, Methods and Results Blood samples were collected from local residents in Sha Tin Village and Dalu Street in 1982, 2004 and 1985, respectively, and the sera were separated and stored in -20 ℃ freezer. Before the test, serum 1
