WNV Levels Elevated in Los Angeles County

WNV first emerged in Los Angeles County in 2004, and since has caused significant numbers of illnesses, including hospitalizations and deaths. Los Angeles County has experienced increased levels of WNV activity for the past 6 years. Each year, between 150 and 300 people in Los Angeles County are identified with WNV infection. While everyone is at risk for WNV, people over 50 and those with health problems are at greater risk of serious illness, this can include meningitis (brain infection), encephalitis (swelling of the brain) and limb paralysis. 

The Los Angeles County Department of Public health urges all residents to limit the spread WNV by stopping mosquitoes from infesting your home and yard, and to protect yourself and your family from mosquito bites by using repellant when outdoors.
