SANTA ANA, Calif. (AP) -- Orange County health authorities say an elderly Seal Beach woman with underlying medical conditions and complications of a West Nile virus infection has died.
The county health agency said in a statement Tuesday that test results received this week confirmed the infection. The woman, who was in her 80s, had a severe form of the infection when she died last week.
Orange County has had 40 West Nile virus infections this year, the most in California.
The virus is mosquito-borne, and health officer Dr. Eric G. Handler says West Nile activity in Orange County tends to peak in August and September, but continues into the fall.
