Countries At Risk
Japanese Encephalitis is predominantly found in India and Southeast Asia and a very remote part of North East Australia.
Japanese Encephalitis is a viral disease that spreads through culex mosquitoes that breed in areas with a lot of water. Although uncommon in travellers, it continues to be a significant public health concern in endemic regions, particularly in rural and agricultural areas.
Most infections don’t show any symptoms, however in serious cases, it can cause brain inflammation, convulsions, lifelong nerve damage, or death. The World Health Organisation estimates that Japanese Encephalitis generates 68,000 clinical cases every year, and the death rate is significant for severe cases.
The best approach to preventing Japanese Encephalitis is vaccination, however not everyone has easy access to it. Some countries, such as China and Japan, have implemented national vaccination programs, whilst others face challenges due to limited financial resources, lower public awareness, or poor healthcare infrastructure. Rural regions may also experience increased risk because of proximity to mosquito breeding areas and limited access to services

Travel Precautions
Japanese Encephalitis is spread through mosquito bites. The mosquitoes that carry the virus typically breed in areas with birds and pigs, making them more prevalent near rice fields and agricultural farms. To reduce the risk of mosquito-borne diseases, it is crucial to use a DEET-based insect repellent for added protection.
Signs & Symptoms
Most people infected with Japanese Encephalitis show no symptoms or experience only mild flu-like symptoms. In rare cases (about 1 in 250 people), the infection can spread to the brain, causing seizures, confusion, and paralysis. There is no cure for Japanese Encephalitis, and treatment focuses on supporting the body while it fights the infection, often through fluids and oxygen.
The Vaccination
The Japanese Encephalitis vaccination consists of two doses administered one month apart. An accelerated schedule is also available, allowing the vaccine to be completed over the course of one week. The vaccine is recommended for travelers planning outdoor activities or staying near farms or rice fields. Protection lasts for two years.
