As of August 2, 2018, Fairfax County has reported one confirmed case of West Nile Virus (WNV); this is the first known human case of WNV in Virginia this year. The patient is recovering in the hospital.
WNV is rare. People may be exposed to WNV when bitten by an infected mosquito. About 80% of people infected with WNV have no symptoms. Those who do may experience fever, headache, joint pain, vomiting, and rashes, among other symptoms. If you have symptoms, please contact your doctor.

Protect Yourself Against Mosquito-Borne Diseases
You can take precautions to protect yourself and your loved ones against mosquito-borne diseases like West Nile.
Remember the “Three S’s” of preventing exposure to mosquitos:
- Spill – Also known as “tip
and toss,” this step is all about getting rid of standing water. Mosquitos
can lay eggs in just a bottle cap full of water! For this reason, it is important
to “spill” any containers that have collected water. Look out for water that
has collected in and around your yard. Drain, fill in, or cover these areas to
prevent mosquitos from accessing the water.
- Screen – Place screens over containers
you cannot empty, such as fountains or water catchment basins. This will prevent mosquitos from
laying their eggs in these containers. Screen any doors, windows, or other
openings to your home so that mosquitos cannot enter.
- Spray – Use repellents containing DEET, picaridin, IR3535, or lemon eucalyptus oil. Especially if you are being bitten by mosquitos, or plan to spend time outdoors. These repellants can be “sprayed” on skin and clothing. Wearing long sleeves and pants can also help protect you against mosquito bites.

Treatment for West Nile virus and other mosquito-borne diseases will depend on the individual case. Please contact your doctor if you have symptoms of a mosquito-borne illness.
