Wilma Wooten, M.D., M.P.H, County of San Diego Public Health Officer, and Gary Erbeck, Director, County Department of Environmental Health Vector Control, urge the public to take the following steps to protect themselves against WNV:
- Use insect repellent when outdoors, especially at dawn and dusk, when mosquitoes are most active
- Use insect repellent with DEET, Picaridin, oil of lemon eucalyptus, or IR3535
- Do not sleep outside, unprotected, while camping; wear long sleeves and pants
- Ensure screens on windows and doors fit tightly and have no holes or other damage
- Check your property weekly for mosquito breeding sources; go to www.SDFighttheBite.com for a mosquito prevention checklist
- Report green pools to County Vector Control
Most people infected with WNV do not develop any symptoms or become seriously ill. Nearly one in five who do fall ill may suffer from headache, fever, nausea, fatigue, skin rash or swollen glands. Approximately one in 150 people infected with WNV develop more serious neurological effects such as meningitis, encephalitis or myelitis. If you suspect you have WNV, contact your healthcare provider.
