"West Nile virus continues to be a serious health threat to residents in Los Angeles County,'' county Health Officer Dr. Muntu Davis said in a statement.

Residents should protect themselves from diseases spread by mosquitoes by using EPA-registered mosquito repellent products, especially during the peak mosquito season, which lasts from June to November in Los Angeles County.''
