West Nile Spreads in California

The West Nile virus is moving into the most populous areas of Southern California.

More than two dozen people and nearly a thousand birds in Southern California have been infected since June.

Today health officials doused bug spray on the Los Angeles County Arboretum and Botanical Garden in Arcadia. That follows an

announcement yesterday that a dead crow discovered in Simi Valley

had tested positive for West Nile.

Health officials say symptoms of the disease are usually so mild

to people that they are believed to go unnoticed in most cases.

About 18 to 19 percent of cases develop into mild flu-like

symptoms. About one percent of cases can be fatal.

Health officials urge people to stay away from mosquitoes, which

transmit the virus from birds to humans and horses.
