Three more birds have tested positive for WNV in Sonoma and Marin County by the Marin/Sonoma Mosquito and Vector Control District in cooperation with the California State Health Department. The birds were reported from the following County /Cities: Marin County - 1 American Robin from Novato in the area of Queva Vista submitted on 10/11/2004. Sonoma County - 1 Hermit Thrush from Guerneville in the area of Cutten Dr. submitted on 10/8/2004 and 1 Western Scrub-Jay from Sebastopol in the area of Nora Ave. submitted on 10/6/2004. This brings the total of WNV positive dead birds to sixty-three in the two counties (46 in Sonoma County and 17 in Marin County).
Birds will still be accepted from all zip codes in the two Counties. The California Department of Health Services will now be accepting dead birds from all cities/zip codes in both Marin and Sonoma until further notice. Although the following areas are considered endemic to West Nile Virus, Cotati 94931, Forestville 95436, Petaluma 94952 and 94954, Rohnert Park 94928, Santa Rosa 95403 and 95404, Sonoma 95476, Sebastopol 95472, San Rafael 94901 and Tomales 94971, the Marin Sonoma Mosquito and Vector Control District and the California Department of Health Services want to gather more information on where and how long the virus will continue to present itself into the fall and winter months.
The detection of WNV in wild birds indicates the virus is present. No human cases have been reported positive at this time in either County. The District is checking all know mosquito breeding sites and setting adult mosquito traps in the areas where the birds have been found. We ask that the public remain diligent in their own mosquito control efforts by checking their yards for breeding sources since they are generally the main source for mosquitoes. Symptoms of WNV range from mild flu-like conditions, such as fever, headache, and nausea to a stiff neck, restlessness, stupor, delirium, and convulsions. Most cases are mild; however, fatalities can occur in extreme cases. There is no vaccine for WNV.
