Japanese encephalitis is spread by the Culex mosquito. These mosquitoes are medium-sized, brown, and have whitish markings on the abdomen. They usually bite at dusk and after dark. By day, they rest in and around homes and other structures and near plants and vegetation. Japanese encephalitis mostly affects people in Asia and the western Pacific. Most people do not become seriously ill, however severe cases of Japanese encephalitis can damage the brain and even cause death.
