Foreclosures targeted in West Nile sweep

April 2, 2010 12:00:00 AM PDT
Authorities in Riverside County are so worried about West Nile virus following heavy winter rains that that they are arming themselves with pesticide. Foreclosed homes are of particular concern as rain water has filled swimming pools on those properties, leaving behind stagnant water which is a mosquito breeding ground.

As a result, Riverside County Vector Control workers are applying pesticide to pools and other potential mosquito breeding grounds. So far, pesticide has been applied at 87 locations.

West Nile virus is transmitted to humans and animals through a mosquito bite. Mosquitoes become infected when they feed on infected birds.

The risk of serious illness to humans is considered by experts to be low but people with weak immune systems and the elderly are at the greatest risk for developing serious illness.
