Health experts say a blue jay in Eau Claire County and a horse in Chippewa County have tested positive for West Nile Virus. Experts say mosquito’s feed off of infected birds and animals and then spread the virus to humans by biting them.

Richard Thoune, with the City-County Health Department says the vrus has been in the area since 2001, but there has never been a case of human West Nile Virus reported in Eau Claire County.

To reduce mosquito breeding, Thoune suggests eliminating standing water, using insect repellent, eliminating exposed skin, and keeping tall grass, weeds and vines cut down around your yard.

Thoune says mosquitoes become more predominant in the later summer months.

"With respect to mosquito's and West Nile Virus there's a tendency for West Nile Virus to be greater later in summer when mosquito's are more active. While we may think they're more active now they tend to be even more greater in the end of July and August, “ Thoune said.
