West Nile Virus: Care Instructions
West Nile virus is an infection spread to humans by mosquitoes. Most people who get the virus don't get sick. But when symptoms do occur, they appear 2 to 14 days after the bite and include fever, headache, body aches, and sometimes a skin rash. It's usually a mild illness. In rare cases, West Nile virus may affect the brain, causing serious illness that can lead to long-lasting problems.
There is usually no specific treatment for the West Nile virus. Your body has to fight the infection on its own. In mild cases of West Nile, symptoms usually last for 3 to 6 days, and you can recover at home. If you get a more severe case of West Nile, symptoms can last for weeks or months, and you may need to stay in the hospital so you can get medicine to help you recover.
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 or nurse advice line (811 in most provinces and territories) 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?
- If you have symptoms, take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). 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.
- Get plenty of rest. You may feel well enough to continue your normal activities.
- Try to be patient while you are recovering. It may take several weeks or months to recover fully.
