Details

This disease is spread through the bite of an infected mosquito normally between sunset and sunrise. It is most common in rural farming areas of Asia. Most infections have few symptoms and may not be recognised but severe cases can lead to inflammation of the brain and other symptoms which can be fatal.

Risks to travellers are generally very low but vaccination should be considered by people intending to spend a significant length of time in rural areas, particularly during the transmission season (monsoon). The vaccine can be administered on two schedules- either a course of 2 injections given 28 days apart or as an accelerated course of 2 injections given 7 days apart. The accelerated course is not suitable for all travellers, your Travel Nurse will advise.
