SPOTLIGHT ON JAPANESE ENCEPHALITIS
If you are travelling to South East Asia or the Indian Subcontinent then this illness is something that could affect you and is preventable through vaccination. It has received more publicity recently as an outbreak has been reported for the first time in Australia. It is transmitted by the bite of a mosquito, which is most active between dusk and dawn. Bite avoidance remains extremely important to prevent mosquito-borne illnesses.
The Japanese Encephalitis virus causes fever, headache, encephalitis, meningitis, seizures and other nerve problems. There is no treatment other than supportive care and 1 in 250 people infected will have more severe illness.
It is more likely to occur in travellers having a prolonged stay in rural areas or travel to rural areas during the transmission season. Anyone with pre-existing medical problems, under 10 years or over 50 years is more at risk of serious disease.
It is advisable to vaccinate:
Those likely to be frequently exposed to bites in rural infected areas (e.g. backpackers, agricultural workers, volunteers).
Long stays (e.g. more than one month) in infected areas.
Repeated visits to risk areas (e.g. flood plains, rice paddies, marshlands).
Short stays during epidemics/outbreaks.
Migrants going to live in an endemic area.
Vaccination consists of 2 doses of an inactivated vaccine given at least a week apart and ideally 28 days apart. We would recommend you consult your travel health advisor as soon as possible when you have booked your trip to ensure you have all your health needs covered. The consultation costs £20 but you will get this deducted from the cost of any vaccinations you have with us and we will advise you if any are available free through your GP.
