Japanese encephalitis
Japanese encephalitis is an infection spread by Culex mosquitoes. These mosquitoes bite mainly from dusk until dawn.
Disease symptoms can occur five to fifteen days after the infection:
- Fever
- Muscle aches
- Headaches
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.
The risk of Japanese encephalitis is generally low for travellers, but it does increase with long-term or frequent stays or stays in rural areas.
Risk areas
This disease occurs only in South and Southeast Asia (from India to Japan) and the most Northeastern part of Australia (map).
Prevention
Protection against mosquitoes
Closely observe the mosquito-repellent measures in the evening and night.
Vaccination
A good and safe vaccine is available.
In case of symptoms
Seek medical advice if you suffer any symptoms.
