TULSA - The Tulsa River Parks Department is taking precautions to protect residents from West Nile Virus.
Due to an unusually high number of mosquitos and gnats, River Parks crews are spraying the East Bank Trail.
Beginning at 9 p.m. Friday, crews will be out from 11th Street to 71st Street.
City leaders are asking people to avoid the area while they're using these chemicals.
State health officials have now confirmed nine new cases of West Nile in Oklahoma, bringing the total to 101.
The record of 107 cases was set back in 2007 when eight people died from the virus.
This year, five people have died from West Nile.
Health officials say West Nile will remain a threat until the first freeze, usually in late October or early November.
