CDFA is working with the California Department of Public Health to detect and respond to the disease in California.
West Nile virus is transmitted through the bite of Culex pipiens mosquito, commonly called a house mosquito, which picked up the virus by feeding on an infected bird.
"Mosquito-borne illnesses are spread through the bite of an infected mosquito", states William Grow, MD, FACP, district health director.
Michigan: The Marquette County Health Department says the WNV has been found in a crow this month. The press release also 11 of the 102 counties in IL have reported positive samples in mosquitoes or birds. Unfortunately, with the added temperature spike comes the increase of West Nile Virus (WNV) vectors, most notably mosquitoes. "However, people over the age of 50 and those with compromised immune systems are more at risk". Four out of five people infected with the virus won't show symptoms.
Most people won't experience any symptoms, but if they do, they can include fever, nausea, headaches and muscle aches.
DAWN and DUSK are times to avoid being outdoors.
Repel - when outdoors, wear shoes and socks, long trousers and a long-sleeved shirt, and apply insect repellent that contains DEET, picaridin, oil of lemon eucalyptus or IR 3535 according to label instructions.
DEFEND yourself by using an effective insect repellent.
Mosquitoes can breed in catch basins, tire swings, buckets and anything else that holds standing water.
Leaders are reminding people to be sure to fit windows with tight-fitting screens and fix broken screens. Mosquito repellents that contain the active ingredients DEET, Picaridin, or oil of lemon eucalyptus work best. Change water in birdbaths, fountains, kiddie pools, and animal troughs at least twice each week.
Other species at risk for WNV infection are birds and horses.
