Disease Info

Diseases Japanese Encephalitis B

The Disease

Japanese Encephalitis is an illness caused by a virus known as a Flavivirus. Symptoms include: fever, headache and convulsions and in some cases can lead to meningitis and cranial nerve paralysis. However, in some cases it can cause inflammation of the brain (Encephalitis), leading to permanent brain damage and even death. Japanese Encephalitis is passed to humans by bites from infected mosquitoes.

Distribution

Japanese Encephalitis is only found in South-East Asia, East India, the Far East, and tropical North East Australia. It is particularly common in rural agricultural areas. Most cases occur after the rainy season or floods.

Vaccination

Vaccination against Japanese Encephalitis normally requires a course of three doses. The second dose is normally given seven days after the first, with the third dose given 28 or 30 days after the first, depending on the vaccine.
An accelerated course of two doses given one week apart may in some cases be available, with a booster dose given three months later. This course gives a lower level of protection and lasts for less time. Japanese Encephalitis vaccine cannot be given to children under 1 year of age.  Vaccination should always be completed at least ten days before travelling to allow any delayed allergic reaction to the vaccine to be dealt with. One month is required to develop full immunity

Notes for Travellers

Vaccination should be considered for repeated visits to, or prolonged stays in endemic areas especially if staying in rural areas. Vaccination is important for infants and children who may be more likely to get serious disease. Short stays in rural parts can also pose a risk, particularly during epidemics that often follow the start of the rainy season when mosquitoes are most active. Anyone travelling to South-East Asia or the Far East and travelling through areas of rice fields or marshland, or doing activities considered being high-risk, such as camping, backpacking or cycling should be vaccinated. Furthermore those who intent to be involved in any farming activities in the risk areas should seek advice on an individual basis.
