BRENTWOOD, Calif. (BCN) – The first case of the year was found recently in a dead American crow in Brentwood, according to the Contra Costa Mosquito & Vector Control District.
Since 2005, 75 people in Contra Costa have been diagnosed with West Nile virus. Two people died from the disease in 2006. The district said in a press release, “Certain birds carry WNV. Once a mosquito bites an infected bird, the mosquito can become infected. Mosquitoes can spread the virus when they bite another bird or person.”
