Japanese encephalitis (JE)

Japanese encephalitis (JE), the leading cause of viral encephalitis in Asia, causes an estimated 30,000 to 50,000 cases and 10,000 to 15,000 deaths each year, mostly among children under 15 years of age. There is no specific treatment for JE. Vaccination is the single most important measure for controlling the disease.
