Chippewa Valley area has state's first West Nile cases of year
Wisconsin has recorded its first animal cases of West Nile disease this spring.
State health officials said a horse in Chippewa County and a blue jay in Eau Claire County have tested positive for the mosquito-borne virus.
That's an early warning for people to heed.
Last year, 12 humans in Wisconsin got sick from West Nile and 17 horses and 47 birds also tested positive.
Officials said the blue jay was already dead when it was found last month.
