Around 1 per 250 people infected with Japanese encephalitis develop more severe symptoms as the infection spreads to the brain. This usually occurs 5 to 15 days after the person is infected.
Those with a severe infection might experience convulsions, tremors, disorientation, coma, neck stiffness and paralysis. In infected children, common symptoms include seizures.
