WNV 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. 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.
