Japanese encephalitis (JE) is a serious infection caused by the Japanese encephalitis virus.
- It occurs mainly in rural parts of Asia.
- It is spread through the bite of an infected mosquito. It does not spread from person to person.
- Risk is very low for most travelers. It is higher for people living in areas where the disease is common, or for people traveling there for long periods of time.
- Most people infected with JE virus don’t have any symptoms. Others might have symptoms as mild as a fever and headache, or as serious as encephalitis (brain infection).
- A person with encephalitis can experience fever, neck stiffness, seizures, and coma. About 1 person in 4 with encephalitis dies. Up to half of those who don’t die have permanent disability.
