Japanese encephalitis is a mosquito-borne viral disease. Most commonly found in rural areas where rice farming takes place. The highest rate occurs during the wet season when mosquitos are present in high numbers.
Transmission patterns are highly specific to locations and vary year to year; in some countries, transmission is seasonal and in others, disease occurs all year round. It is most common in southeast Asia and the subcontinent.
Prevention is based on avoiding mosquito bites, especially around sunset time when this mosquito is most active. Also, the use of insect repellents, appropriate clothing, and mosquito nets is recommended for those at risk.
The main symptoms are a headache, encephalitis, convulsions, and meningitis. Majority of people will have a mild illness with a few or no symptoms but those with severe illness can develop permanent neurological problems and will lead to death in some cases.
Vaccination is available and those people who are planning to visit risk areas and prolonged stay should consider getting vaccinated. Book a consultation in advance to get the full course of vaccine before traveling.
