Abstract
ObjectiveTo monitor the level and distribution of antibody against Japanese B encephalitis virus (JEV) among healthy people in Tongzhou district of Beijing, so as to provide basis for effective prevention and control strategies under the new situation.
MethodsA total of 250 healthy people were selected from local residents of over 6 months according to the random sampling method. Antibody were detected by plaque reduction neutralization test.
ResultsThe positive rate of JEV antibody was 84% (210/250) in 2017. The positive rates of antibody showed statistically significant differences among areas and among age groups (P<0.05). There was no statistically significant difference in positive rates of JEV antibody among different genders and among registered population (P>0.05).
ConclusionsHigh positive rate of antibody against JEV among healthy people in Tongzhou district of Beijing formed an antibody basis to prevent large scale epidemics of JEV. Disease prevention for mobile population and old people as well as propaganda and education on mosquito-proof and mosquito-repellent should be concerned, so as to keep the incidence of JEV at a low level.
