Causes, incidence, and risk factors

Encephalitis is a rare condition. It occurs more often in the first year of life and decreases with age. The very young and the elderly are more likely to have a severe case.
Encephalitis is most often caused by a viral infection. Many types of viruses may cause it. Exposure to viruses can occur through:
  • Breathing in respiratory droplets from an infected person
  • Contaminated food or drink
  • Mosquito, tick, and other insect bites
  • Skin contact
Different viruses will occur in different locations. Many cases will tend to cluster in a certain season.
Encephalitis caused by the herpes simplex virus is the leading cause of more severe cases in all ages, including newborns.
A number of viruses for which there is now a vaccine may also cause encephalitis. These include:
