Drought making west-nile virus a bigger threat

SIOUX FALLS, S.D.(KELO)- The drought is making west-nile virus an even greater threat.

That, according to Sioux Falls city officials, who are gearing up to fight west nile.

Spraying is the most visible part of control efforts, but Control Coordinator Denise Patton says most of the work comes in the form of treating standing water ponds.

In case you’re wondering, South Dakota has over 40 species of mosquitoes.

Only four or five spread virus readily.
