Public Health Alert: Two confirmed cases of West Nile Virus in Archuleta County
West Nile virus is most commonly spread through the bite of an infected mosquito. While most people who become infected do not develop symptoms, some may experience a mild illness. Serious illness is uncommon, but residents should take reasonable precautions to reduce their risk of mosquito bites.
Know the Symptoms
Most people infected with West Nile virus do not develop symptoms. When illness does occur, symptoms may include:
- Fever
- Headache
- Body aches
- Joint pain
- Vomiting or diarrhea
- Skin rash
- Fatigue or weakness
- What to Do If You Become Sick
There is currently no specific medication to treat West Nile virus. For people experiencing mild illness, treatment generally focuses on relieving symptoms. Rest, drinking plenty of fluids, and over-the-counter medication such as acetaminophen can help with fever, headaches, and body aches. Seek medical attention promptly for severe symptoms, including high fever, severe headache, neck stiffness, confusion, muscle weakness, tremors, numbness, or paralysis. People who are older or who have certain underlying health conditions or weakened immune systems are at greater risk for serious illness.
Prevent Mosquito Bites
The best way to protect yourself and your family from West Nile virus is to prevent mosquito bites:
- Use an EPA-registered insect repellent when spending time outdoors.
- Wear long, loose-fitting clothing such as long sleeves and pants when practical.
- Avoid outdoor activities around dusk and dawn, when mosquitoes that commonly spread West Nile virus are most active.
- Keep mosquitoes outside by using screens on windows and doors and repairing holes in screens.
- Eliminate standing water around your home. Empty or change water in items such as buckets, flowerpots, birdbaths, tires, children’s toys, and other containers at least weekly.
- For larger or permanent areas of standing water that cannot be eliminated, consider appropriate mosquito-control measures or contact a local mosquito control professional for guidance.
