Abstract:
453 cases of acute encephalitis syndrome were studied in the year 2002 at the National Institute of Pediatrics and 21 provinces of North Vietnam. Using Aedes albopictus clone C6/36, from CSF, 6 strains of Japanese encephalitis virus were isolated. By ELISA – Sandwich technique and indirect immunofluorescent assay, 4 virus strains were determined, including 4 strains of JE virus and 2 unknown viruses. 43.26% of cases of acute encephalitis syndrome were caused by JE virus. JE incidence in children of 1-4 years old reduced from 37.62% in 1989-1995 year period to 11.22% in 2002, due to the intensive immunization for children 1-5 years old.
