State confirms first human West Nile Virus case of 2017 stat : The Mercury News

SACRAMENTO — California's first human West Nile virus case of the year has been confirmed in Kings County. The virus is spread to humans and animals by the bite of an infected mosquito. The risk of serious illness to most people is low, but some individuals can contract serious illnesses such as encephalitis and meningitis, according to the Department of Public Health. People who are 50 or older and those with diabetes or hypertension have a higher chance of getting sick. The Department of Public Health said heavy rains this winter contributed to an increase in mosquito breeding sites, but it is unknown what impact the wet weather may have on virus transmission risk in humans.




THOUSAND PALMS, CA - Mosquitoes collected in Thousand Palms tested positive for West Nile virus, local vector control officials said Monday. West Nile virus is transmitted to humans via the bite of infected mosquitoes, which become infected when feeding on birds carrying the virus. Vector control officials will be posting disease notification signs in communities near the trap locations and will install more traps. The positive test result came from a sample of about 30 mosquitoes from a trap located on Varner Road between Cook Street and Monterey Avenue, according to the Coachella Valley Mosquito and Vector Control District. CVMVCD officials say the virus is expected to be active regionally throughout the summer.
