West Nile encephalitis in children: 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. This illness can cause confusion, a high fever, and a severe headache. Other symptoms can 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.
Most people with this illness get better over time. But your child may have some symptoms for several months or longer.
How can you care for West Nile encephalitis?
- 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.
