The number of West Nile virus infections in Louisiana has reached 215, with 39 new cases reported this past week.
No new deaths were added in the latest report. The death toll from the virus so far this year stands at 10.
Louisiana's health department says the state is experiencing its highest number of West Nile cases in years. And Hurricane Isaac is getting some of the blame. The storm left behind a lot of standing water, providing breeding areas for mosquitoes.
Humans are infected when they are bitten by infected mosquitoes.
Technicians with the Contra Costa County Mosquito and Vector Control District spray insecticide in Brentwood, Calif., last month. Workers fogged areas of the county that had an increase in the numbers of mosquitoes carrying the West Nile virus.
The numbers for West Nile virus cases continue to rise, up 35 percent in the last week. But the Centers for Disease Control and Prevention is confident the nation has turned the corner on its worst-ever epidemic of West Nile virus disease.
