Japanese encephalitis (JE) is an infection of the brain caused by the Japanese encephalitis virus (JEV). While most infections result in little or no symptoms, occasional inflammation of the brain occurs. In these cases symptoms may include headache, vomiting, fever, confusion, and seizures. This occurs about 5 to 15 days after infection.
JEV is generally spread by mosquitoes, specifically those of the Culex type. Pigs and wild birds serve as a reservoir for the virus. The disease mostly occurs outside of cities. Diagnosis is based on blood or cerebrospinal fluid testing.
The disease occurs in Southeast Asia including Thailand and the Western Pacific.
Prevention: Japanese encephalitis vaccine, avoiding mosquito bites
Japanese encephalitis vaccination is mandatory for all children in Thailand.
