About West Nile virus

West Nile virus is a potentially serious illness transmitted to humans through the bite of an infected mosquito.

According to the Centers for Disease Control and Prevention, 80% of people who get West Nile virus won’t have symptoms. Those who do develop symptoms typically experience fever, headache, body aches, joint pain, vomiting, diarrhea, or rash. A small number of people will develop severe symptoms affecting the central nervous system, which could be fatal.

There is no vaccine to prevent West Nile virus, and no treatment other than supportive care for the symptoms.

Prevention tips

The Coastal Health District reminds everyone to take precautions to avoid mosquito bites.

Mosquitoes that carry West Nile virus are more likely to bite during the evening, night, and early morning. Wearing insect repellent containing the chemical DEET or picaridin will help keep mosquitoes away. Eliminating standing water around the home and yard keeps mosquitoes from breeding.

The Coastal Health District outlined the Five Ds of mosquito bite prevention:

• Dusk/Dawn: Avoid dusk and dawn activities during the summer when mosquitoes are most active.
• Dress: Wear loose-fitting, long-sleeved shirts and pants to reduce the amount of exposed skin.
• DEET: Cover exposed skin with an insect repellent containing DEET or picaridin, which are the most effective repellents against mosquito bites.
• Drain: Empty any containers holding standing water, including buckets, barrels, flowerpots and tarps, because they are breeding grounds for virus-carrying mosquitoes.
• Doors: Make sure doors and windows are in good repair and fit tightly, and fix torn or damaged screens to keep mosquitoes out of the house.
