California 08/18/10 krcrtv.com: Butte County health officials have confirmed a Chico woman has tested positive for West Nile Virus. The elderly woman was hospitalized with the most severe form of West Nile, and officials say at this time, she is in stable condition. This is the first confirmed human case in Butte County for 2010. “This is an important reminder that West Nile Virus is here to stay,” said Butte County Health Officer Dr. Mark Lundberg. “We know from local surveillance efforts that West Nile Virus is circulating locally in mosquitoes and wild birds. West Nile is active in many parts of Butte County, so all residents need to protect themselves from mosquito bites. Prevention is the key to stopping the spread of the virus.”
California 08/18/10 dailybulletin.com: by Lori Consalvo – As the summer months continue, health officials are finding more and more traces of West Nile Virus throughout the area. In July, two chickens in Fontana tested positive for the virus, according to the San Bernardino County Department of Health. And three mosquito samples in Rancho Cucamonga and Ontario recently tested positive for the presence of the virus, according to the West Valley Mosquito and Vector Control District. The samples were collected using traps that gather female mosquitoes looking for a place to lay eggs, according to a District news release. “We continued detection since May – May was the first detection of West Nile Virus (this year) – and now we’re into August and we’re still seeing West Nile Virus,” said Brian Reisinger, community outreach coordinator for the district. Reisinger said he doesn’t want to alarm the public, but it’s “something that we definitely want to alert people to.” Two contaminated traps were from Rancho Cucamonga – one near Haven Avenue and Manzanita Drive and one near Beryl Street and Baseline Road. The third was in Ontario, near San Antonio Avenue and Sixth Street, officials said. The recent high temperatures help accelerate a mosquito’s lifestyle, Reisinger said. “(A mosquito) can go through life stages in 3 to 4 days because it’s so warm,” he said. “Personal protection is important.” Human infections and reports of mosquitoes carrying the disease has increased this year throughout California. There were 10 human cases in 2009, compared to 15 this year, according to the news release. As for mosquito samples, there were 387 in 2009 and 562 so far this year. In the San Bernardino County area, Reisinger said, there has been one human case reported.

The group of mosquitos was collected from the vicinity of Empire Avenue and El Monte Drive, and the bird was found near West Cypress Road and O’Hara Avenue. “It’s unusual to have our first detection of West Nile virus this late in the year,” said Dr. Steve Schutz, scientific program manager for the district. “But it was only a matter of time. West Nile virus is endemic to Contra Costa County – and California, for that matter.”
California 08/14/10 modbee.com: by Bill Lindelof – Four horses have been diagnosed with West Nile virus this year in the state – in Sacramento, San Joaquin and Madera counties. The outbreak of the virus has prompted the state Department of Food and Agriculture to renew calls for horse owners to vaccinate their animals. The four horses that contracted the virus were either unvaccinated or incompletely vaccinated. Signs of West Nile virus in horses include staggering, stumbling, wobbling, weakness, muscle twitching and inability to stand. Not every horse exposed to West Nile will die. The virus is mosquito-borne and the horse is not contagious to other horses or people. “Outbreaks of West Nile virus are still a risk for horses,” said California State Veterinarian Richard Breitmeyer in a news release. “Horse owners should contact their veterinarians as soon as possible to ensure vaccination status is current.”
California 08/13/10 dailynews.com: Its onset delayed by cooler summer temperatures, the West Nile virus is spreading throughout the San Fernando Valley, where disease-carrying mosquitoes have been found in eight communities, officials said Friday. Mosquitoes collected from Reseda, Panorama City and Canyon Country tested positive Friday for the virus, said Crystal Brown, a spokeswoman for the Greater Los Angeles County Vector Control District. And recently, the disease was found in mosquitoes captured in Winnetka, Woodland Hills, Encino, Granada Hills and the Hansen Dam Recreational Area in Lake View Terrace. In addition, dead birds found in Stevenson Ranch in March and June tested positive for the virus. No human cases have been reported in Los Angeles County this year, according health officials, although two were reported in Kern County and one in San Bernardino County. West Nile virus infects birds and can be transmitted by mosquito to humans. The elderly and those with weak immune systems are most at risk, and about one in 150 infected people will require hospitalization. Victims of West Nile typically experience flu-like symptoms, although it can lead to potentially deadly complications such as encephalitis or meningitis. Statewide, 219 dead birds and 562 mosquito samples have tested positive for West Nile virus so far this year. In L.A. County, 11 dead birds and 11 mosquito samples have been found.
California 08/13/10 go.com: A dead squirrel discovered in San Mateo is the first in San Mateo County to test positive for the West Nile virus this year, local scientists said. The otherwise unmarked squirrel is a sign of West Nile’s increasing pervasiveness all over California in 2010, Chindi Peavey, laboratory director for the San Mateo County Mosquito and Vector Control District said. “West Nile virus is much more prevalent this year throughout the state,” she said. “It’s not something people should panic about, but yes, we have it.” Birds are the most common carriers of the virus, Peavey said. Human infection typically occurs from a bite from a mosquito that has previously bitten a bird. The squirrel was found on July 28 by a lab technician on a road near a creek and tested positive for West Nile virus this week. Mosquitoes and a bird in Oakley were found to be carriers of West Nile virus on Wednesday, officials said. Teams in Santa Clara, Sacramento, Yolo and Placer counties have all fogged their areas with mosquito deterrent to rid any threat of West Nile virus.

Florida 08/18/10 foxnews.com: Four Florida residents have died from a mosquito-borne disease that normally afflicts horses, health officials reported on Tuesday as the swampy state enters peak season for mosquito-borne illnesses. Health officials said last month that two Tampa-area residents had died from eastern equine encephalitis, a viral disease that inflames the brain. Two additional deaths from the disease known as EEE have since been confirmed, one in the state capital of Tallahassee and one in the northwest Florida town of Sopchoppy. The disease mostly affects unvaccinated horses but a handful of human deaths are recorded each year, according to the Centers for Disease Control and Prevention. There is no human vaccine for the disease, which kills a third of its human victims and often leaves survivors with significant brain damage. The Florida Department of Health is also tracking two other less deadly mosquito-borne diseases, West Nile virus and dengue fever. EEE and West Nile virus have been detected in 43 of Florida’s 67 counties, while dengue cases have been confirmed in two south Florida counties, Monroe and Broward, according to the state Department of Health. The dengue virus began showing up in Florida in 2009 after an absence since its last major outbreak in 1934. At least 28 confirmed cases of domestically transmitted dengue fever have been reported in Florida this year, along with 67 foreign-acquired cases. The disease is more prevalent in Central and South America.
