The brain

Overview

West Nile encephalitis is an illness that causes inflammation in the brain. It is caused by the West Nile virus. The virus is carried by mosquitoes. Encephalitis can cause confusion, a high fever, and a severe headache. Other symptoms include nausea and vomiting, and body aches. West Nile virus is not spread by touching a person who has the virus. Almost all cases are from mosquito bites. It appears that the virus can be passed through breast milk. Talk to your doctor about this if you are breastfeeding.

Most people with the illness get better over time. But you may have some symptoms for several months or longer.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Be safe with medicines. Read and follow all instructions on the label.
  • Do not take two or more pain medicines at the same time unless the doctor told you to. Many pain medicines have acetaminophen, which is Tylenol. Too much acetaminophen (Tylenol) can be harmful.
  • Eat a balanced diet and get plenty of rest. This helps your body heal.
  • Follow your doctor's advice on drinking fluids. Too much fluid sometimes can cause more swelling in the brain.
  • Keep the lights dim if your eyes are sensitive to light.

When should you call for help?

Call 911 anytime you think you may need emergency care. For example, call if:

  • You have a seizure.

  • You have a fever.
  • You have a severe headache.
