The virus that causes Japanese encephalitis is called an arbovirus, which is an arthropod-borne virus. Mosquitoes are a type of arthropod. The virus is transferred to a human when an infected mosquito sucks that person’s blood. Once in the body, the virus travels to various glands where it multiplies. The virus can then enter the bloodstream. Ultimately, the virus settles in the brain, where it causes serious problems. Japanese encephalitis begins with fever, severe headache, nausea, and vomiting. As the tissue covering the brain and spinal cord (the meninges) becomes infected and swollen, the patient will develop a stiff and painful neck. By day two or three, the patient begins to suffer the effects of swelling in the brain. v Problems with balance and coordination v Paralysis of some muscle groups v Tremors v Seizures v Lapses in consciousness v A stiff, mask-like appearance of the face.
