Encephalitis is an acute inflammation of the brain and can be caused by both viral and bacterial infections. Japanese encephalitis, which is caused by the Japanese encephalitis virus, is more prevalent in the region than other forms of the illness.
Symptoms include high fever, convulsion and frigidity around the neck area.
The mosquito-borne disease can cause fever, convulsions and coma and is more likely to kill children than adults.
The virus affects membranes around the brain and usually causes mild symptoms, but can lead to high fever, brain damage, coma and death. It is the leading cause of childhood encephalitis and viral encephalitis in Asia.
