The Greater L.A. County Vector Control District says it has confirmed West Nile Virus (WNV) in a mosquito sample from the City of Signal Hill, as well as from a sample in the City of Whittier.

Health authories have said residents should treat WNV as if it’s everywhere, because it’s now basically endemic the area.

WNV is transmitted through the bite of an infected mosquito. There’s no cure for West Nile Virus, LB’s Dept. of Health & Human Services says about one in five people exhibit symptoms which usually occur within 5-15 days and can include fever, body aches, rash, nausea, vomiting and headache.

About one in 150 people develop more serious neurological diseases, including encephalitis (brain inflammation) or paralysis that require hospitalization; severe symptoms can include high fever, muscle weakness, neck stiffness, coma, paralysis — and possibly death — and LB’s Health Dept. urges anyone displaying such symptoms to seek immediate care. Those at highest risk for severe cases of West Nile virus are the elderly and people with weakened immune systems, says LB’s Health Dept.

The virus arrived locally in 2004 and hit LB hard (especially ELB and SE LB). An elderly woman in the area of Clark Ave/Wardlow Rd. died of WNV…and dead crows (a species for whom WNV is virtually always fatal) were visible throughout LB and SE L.A. County.
