Much like killer bees, Lyme disease and bird flu, West Nile virus is beginning to slip from the public's consciousness.

That would be unwise. While health officials concede the overall risk of humans contracting the mosquito-borne illness is low, the threat is still there.

Last month, the state Department of Public Health announced that a Tulare County woman had tested positive for the virus, the first reported human case this year. She has been hospitalized and is recovering.

In all, the health department reports that, so far in 2008, more than 40 birds in 19 counties have tested positive for West Nile virus.

One of those birds was found in Simi Valley the first week of July. Last year, as of November, 15 infected birds, mostly crows, tested positive for West Nile in the county.

In 2007, there were 380 human cases in California, with 21 of those proving fatal. No deaths occurred in Ventura County from the virus, but one human case was reported.

In Los Angeles County, five people died from the virus, according to the state health department figures.

These numbers underscore the importance of taking precautions and paying renewed attention to the West Nile virus, which is transmitted to humans and animals through the bite of a mosquito that has fed on an infected wild bird.

Mosquito activity is greatest in August, September and early October — a time when Californians need to be the most cautious in preventing a buzzing mosquito from taking a bite, especially the elderly and those with weakened immune systems.

Health officials offer these simple precautions: Wear long pants and shirts when outdoors and mosquitoes are present; use insect repellent; eliminate standing water; use mosquito netting over strollers and infant carriers; and, make sure doors and windows have tight-fitting screens.

Now that the first infected bird has turned up in the county, health officials expect additional birds will be found. Residents finding a dead bird should call 877-968-2473 to report it. To report potential mosquito-breeding grounds, call 658-4310.

West Nile virus, which first slipped into the county in April 2003, is likely here to stay. But, there's no need lock the doors and cower in the corner with a can of bug repellent at the ready.

All residents really need is a renewed sense of awareness about the dangers of West Nile virus and some timely precautions before heading out to enjoy our beautiful weather — worry-free.
