CALIFORNIA DEPARTMENT OF PUBLIC HEALTH REMINDS CALIFORNIANS TO PROTECT THEMSELVES FROM MOSQUITOES THAT CARRY WNVJun 3, 2008
Most individuals who are infected with WNV will not experience any illness. Individuals 50 years of age and older have a higher chance of getting sick and are more likely to develop serious symptoms when infected with WNV. Recent data also indicate that those with diabetes and/or hypertension are at greatest risk for serious illness.
California has one of the most comprehensive West Nile Virus surveillance and control systems in the U.S. The state deploys surveillance and detection technology to track specific areas of West Nile Virus activity and alert local agencies so they can target their mosquito control activities.
California's WNV Web site - www.westnile.ca.gov - has been updated to make it easier for the public to find the latest information on WNV activity in the state. In order to help identify WNV activity, Californians are encouraged to report all dead birds and dead tree squirrels on the Web site or call toll-free 1-877-WNV-BIRD (968-2473).
