Three Horses Infected With West Nile Virus

Yakima, Wash. - State health officials have confirmed three more horses in Yakima County are infected with West Nile Virus.

This comes after the state's first human case on Thursday, in a 40-year-old Pierce County man.

A Yakima County horse was Washington's first case of the disease this year.

Thursday's cases come from three other, non-vaccinated animals.

Yakima health district specialist David Cole said people should be aware that the disease is here.

A few of the ways to control mosquitoes around your house include emptying anything that holds standing water, recycling unused containers and fixing leaky outdoor faucets and sprinklers.

Also, make sure roof gutters drain properly.
