California's first West Nile case this season found in Antelope Valley
Health officials have confirmed the first human case of West Nile virus in California for the 2009 season.
The virus was confirmed in an Antelope Valley resident who donated blood in early June and is not showing signs of illness.
Health officials are working to determine where the patient may have contracted the virus. A dead blackbird found in Lancaster is the second dead bird to test positive for the West Nile virus in the Antelope Valley this year.
