Japanese encephalitis can be a serious illness causing inflammation of the brain. You should consider being immunised against Japanese encephalitis before you travel to certain countries in Southeast Asia and the Far East.
The virus is transmitted by the bite of a mosquito, which feeds from dusk until dawn. Pigs and water birds act as sources of the virus. Thus, the infection is mainly found in rural and semi-rural areas. Transmission can vary by season in individual countries, with highest risk during rainy season. However, other countries have year round transmission.
You will require 2 doses 28 days apart or an accellerated course, which is 2 doses 7 days apart.
