What is Japanese encephalitis?

What is Japanese encephalitis?

  • Japanese encephalitis: A form of encephalitis caused by a flavivirus (Japanese B encephalitis virus - JBEV) and transmitted by mosquito bites. Most cases are mild and asymptomatic but severe cases can lead to death.
  • Japanese encephalitis: A mosquito-borne encephalitis caused by the Japanese B encephalitis virus (ENCEPHALITIS VIRUS, JAPANESE) occurring throughout Eastern Asia and Australia. The majority of infections occur in children and are subclinical or have features limited to transient fever and gastrointestinal symptoms. Inflammation of the brain, spinal cord, and meninges may occur and lead to transient or permanent neurologic deficits (including a POLIOMYELITIS-like presentation); SEIZURES; COMA; and death. (From Adams et al., Principles of Neurology, 6th ed, p751; Lancet 1998 Apr 11;351(9109):1094-7)
