Japanese encephalitis
Japanese encephalitis is an infection spread by Culex mosquitoes. These mosquitoes bite mainly from dusk until dawn.
The risk of Japanese encephalitis is very low for travellers, but it does increase with long-term stays or stays in rural areas.
Disease symptoms (fever, muscle aches, headaches) can occur five to fifteen days after the infection. In most people the disease is mild and the symptoms heal within a few days. A minority develop neurological symptoms with cerebral infections or meningitis. In that case there is a high risk of permanent residual injuries or even death.
No specific treatment is available.
Risk areas
This disease occurs only in South and Southeast Asia (from India to Japan) and the most Northeastern part of Australia (map).
Prevention
