Japanese encephalitis is a viral infection spread by mosquitos causing swelling of the brain, resulting in permanent brain damage or death. According to the World Health Organization at least 50,000 people in Asia develop visible symptoms of Japanese encephalitis each year

Most people infected by the Japanese encephalitis virus do not develop any symptoms, or they get only mild, flu-like symptoms. However, around one person in 250 infected by the virus has serious and severe symptoms, including vomiting, seizures, headache and mental confusion. We would strongly recommend those at risk get vaccinated prior to travel.

Japanese Encephalitis occurs in most countries of Asia, the Indian subcontinent, and remote parts of northeast Australia.

Remember while travelling, be sure to use mosquito nets and avoid insect bites between dusk and dawn when the mosquitos are most active.

The most commonly used vaccine is the inactivated IXIARO vaccine. Injections are recommended for travellers considering outdoor activities in high-risk areas. The immunization against Japanese Encephalitis requires a course of two vaccines over 28 days.
