Japanese Encephalitis (JE) is a serious infection caused by a virus which can result in death or neurological sequela. It occurs in certain rural parts of Asia. Encephalitis means swelling of the brain. Japanese Encephalitis spreads through the bite of infected mosquitoes, but it cannot spread directly from one person to another. Japanese Encephalitis is endemic in China, Japan, Korea, and eastern areas of Russia Outbreaks now occur in previously nonendemic countries including islands in the Torres Strait and northern Australia.
Japanese Encephalitis can cause mild infections with fever and headache or severe infections with encephalitis. As much as 60% of such cases results in death. Symptoms of more severe infection are headache, high fever, neck stiffness, stupor, disorientation, abnormal movements, occasional convulsions (especially in infants), coma, and paralysis.
As with any disease transmitted by mosquitoes, you can prevent exposure to the Japanese Encephalitis virus by:
- Remaining in well-screened areas,Wearing clothes that cover most of the body
- Using an effective insect repellent, such as those containing up to 30% N,N-diethyl metatoluamide (DEET) on skin and clothing.
- Using Permethrin on clothing
The Japanese Encephalitis vaccine can prevent JE, however, the JE vaccine is not 100% effective and is not a substitute for mosquito precautions. People who live or travel in certain rural parts of Asia should get the vaccine. Be sure to check with your Passport Health Travel Medicine Specialist to find out if you’re at risk for Japanese Encephalitis.
