West Nile Virus (WNV) is a mosquito-borne disease that was first detected in the West Nile District of Uganda. Transmitted by mosquito bites, WNV affects humans, horses, some birds, and squirrels. The widespread disease is found in Africa, Asia, the Middle East, and North America. In humans, it causes mild to severe flu-like symptoms such as fever, headache, body ache, and in severe cases, significant neurological symptoms or even deaths. The elderly and those with immune system compromise are most susceptible.
WNV in the United States
In the United States, the first WNV outbreak was reported during 1999 in New York City. The virus spread quickly across the nation during the subsequent 5 years. It was first reported in California during 2002 in Los Angeles and within 2 years, WNV had been confirmed in 58 counties.
What You Should Know
There is no cure for WNV. Vaccines for human are not available yet. People can protect themselves from WNV by taking precautions to avoid mosquito bites, and reducing or eliminating standing water on their property. To help us detect WNV activity, we request that you report all dead birds and squirrels directly to the DEAD BIRD HOTLINE at 877-WNV-BIRD (968-2473) or online at www.westnile.ca.gov
There are many types of mosquitoes found in (your city & county here) including Aedes, Anopheles, Culex, and Culiseta species. Many of them can cause severe health problems.
Management of mosquitoes in the county presents an ongoing challenge due to the variety of species and developmental sites. These habitats range from small backyard sources to marshes with hundreds of acres.
Control of mosquitoes includes:
- Detection and monitoring of mosquito sources
- Removal or alteration of mosquito breeding habitats.
- Application of mosquito insecticides, by ground or aerial equipment.
- Public education and outreach.
(Your city name here) Vector Control District encourages residents to maintain a mosquito-free environment by reducing standing water sites.
Typical abatement procedures are used to gain access to properties to eliminate the source of a mosquito problem (e.g. a neglected swimming pool in the backyard). Local Vector Control Districts prefer to work with landowners and will make every effort to provide help and assistance.
However, if a landowner is unwilling or unable to eliminate a mosquito source (or other nuisance), local districts have the authority to access private property to inspect and abate the source of a problem. They also have the authority to charge a landowner a fee, and place liens upon property (Sections 2053, 2060-2067, and 2855 of the California Health and Safety Code).
