Japanese encephalitis is viral meningitis, also known as Japanese encephalitis. The disease is found mainly in Southeast Asia and has a high mortality rate. Japanese encephalitis is spread to both humans and animals by mosquitoes. The person who falls ill can get severe inflammation with chills, high fever, confusion, anxiety, severe headache and cramps. If the disease develops, it can often lead to the sufferer ending in a coma. There may also be chronic disease symptoms such as emotional instability and deafness. The mosquitoes that spread the virus thrive best in an environment among pigs and the countryside; therefore involves a risk area. The incubation period for Japanese encephalitis is between five and ten days.
