The first mosquito sample testing positive for West Nile Virus this year was confirmed by the Orange County Mosquito and Vector Control District to be found in Garden Grove, the agency said in a news release Monday.
The sample was collected from mosquitoes found near Garden Grove Boulevard and Newhope Street on July 3, officials said. So far, however, no birds or humans in the county have been infected with the virus this year.
The virus is usually transmitted to humans and other animals through mosquitoes, who often contract the illness from birds that feed on them, according to the Centers for Disease Control and Prevention.
Since 2003, the virus has infected more than 6,500 people in California and killed 292, state health officials said.
