No Human Cases of West Nile in Michigan Yet

EAST LANSING, Mich. (AP) -- Just two years after 17 deaths, Michigan so far is reporting no human cases of West Nile virus in 2014.

A snowy winter and wet spring might lead to more mosquitoes, the carrier of West Nile. But that doesn't automatically translate into a greater risk for getting the virus.

Ned Walker, an expert at Michigan State University, says the virus needs hot weather to become potent. The National Weather Service reports only a handful of days of 90 degrees or higher since June.

Mosquitoes pick up the virus from infected birds and then pass it to people. The elderly and people with a weak immune system are considered to be at greatest risk for death.

There were 36 human cases in Michigan last year and 202 in 2012.
