Birds Test Positive for West Nile Virus

(Santa Ana) – The detection of antibodies for West Nile virus (WNV) in two wild birds tested by the Orange County Vector Control District serves as a reminder that individuals should take basic precautions to protect their health.

“Local surveillance efforts have provided the early warning that we hoped for,” said County Health Officer Dr. Mark Horton. “Because the virus is present in Orange County, we could begin to see human cases. It is important that everyone take a few simple precautions to reduce their risk of mosquito bites, which are the primary method of transmission for the virus.”

Basic precautions include:

• Eliminating any standing water from your property to reduce mosquito breeding
• Using insect repellent containing DEET, always following label directions
• Making sure your window and door screens are in good condition
• Limiting outdoor activity at dawn and dusk, when mosquitoes are most active
• Wearing long-sleeved shirts and long pants when outdoors

To date, there have been no locally acquired human cases of West Nile virus infection reported in Orange County. Most people who become infected with WNV do not experience symptoms or become ill. About one out every 150 people infected with WNV may develop a more severe form of the illness and adults over 50 years of age are at increased risk of serious complications from WNV infection. Anyone who develops symptoms such as a high fever, confusion, muscle weakness, severe headaches or stiff neck should seek medical care immediately.

As part of the on-going surveillance program, the Orange County Vector Control District is asking the public to report to them any wild birds that have died recently, especially crows, ravens and birds of prey. The public may call the Vector Control District at (714) 971-2421 or check their Web site at www.ocvcd.org for more information on the reporting of dead birds.
