Japanese Encephalitis Overview

What is Japanese encephalitis?
A person with encephalitis has inflammation and swelling of the brain and the dura, which is the protective sheath that surrounds the brain and spinal cord. Japanese encephalitis is caused by a virus that is transmitted to humans through the bite of a mosquito. Most Japanese encephalitis virus infections cause a mild illness within 2 weeks after the mosquito bite.

What are the symptoms of Japanese encephalitis?
The most common symptoms of Japanese encephalitis include body aches, fatigue, fever, headache, nausea, rash, vomiting, and sensitivity to bright light. Rarely, the infection worsens, causing more severe symptoms, such as neck pain, neck stiffness, high fever, confusion, and seizures.

How does the doctor treat Japanese encephalitis?
Treatment for Japanese encephalitis may include rest, oral fluids, and acetaminophen or nonsteroidal anti-inflammatory medications for pain and fever control. Treatment for severe Japanese encephalitis may include intravenous fluids, medications for seizures, and medications to control swelling in the brain.
