SAN JOSE, Calif. (KCBS) -- At this point in 2007, 33 infected birds had been documented, but this year the number is at least 133, after many turned up in recent weeks in the Sacramento area and in Orange County.
"The more mosquitos that are out there, the greater the risk of transmission of West Nile to people," said Santa Clara County Vector Control Spokesman Russ Parmin.
Mosquitos spread the virus from dead birds to humans.
There is speculation that our dry late winter and spring could mean lower mosquito populations.
Fortunately no humans have tested positive this year for West Nile, though cases typically start cropping up in June.
