Japenese Encephalitis

What is Japenese Encephalitis?

Japanese encephalitis (JE) is a rare disease in travellers, but can have serious consequences. The disease is endemic in 25 countries in Asia and the Western Pacific, not just in Japan. Most of these countries have it as part of the immunisation programme.

JE is caused by bites primarily from mosquitoes which carry the JE virus.

Even though it is rare, 1/3 of people infected show no symptoms, 1/3 of people may be left permanently disabled both physically and mentally and 1/3 of people suffer from inflammation of the brain, which can cause comas, paralysis and death.

Most people infected by the Japanese encephalitis virus have either no symptoms or mild short-lived symptoms, which are often mistaken for flu.

But around 1 in every 250 people who become infected with Japanese encephalitis develop more severe symptoms as the infection spreads to the brain.

This usually happens 5 to 15 days after infection.

The symptoms can include:
  • a high temperature (fever)
  • seizures (fits)
  • a stiff neck
  • confusion
  • the inability to speak
  • uncontrollable shaking of body parts (tremor)
  • muscle weakness or paralysis

Up to 1 in every 3 people who develop these more serious symptoms will die as a result of the infection.

To minimise your risk
  • Use a recommended insect repellent containing either Picaridin, DEET, PMD or OLE (oil of lemon eucalyptus), IR3535 or 2-undecanone
  • Wear appropriate clothing (e.g loose fitting long-sleeved clothes, long trousers, socks and shoes) to minimise exposed skin
  • Use insecticide-treated mosquito nets if you are sleeping or resting in accommodation that is not air-conditioned or sleeping outdoors during the day or night
  • Get Vaccinated
