West Nile Encephalitis in Children: Care Instructions

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.

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

How can you care for your child at home?

• Give an over-the-counter pain medicine, such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin). Be safe with medicines. Read and follow all instructions on the label. Do not give aspirin to anyone younger than 20. It has been linked to Reye syndrome, a serious illness.

• Do not give 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.

• Make sure your child eats a balanced diet and gets plenty of rest. This helps the body heal.
