Fewer West Nile cases this year

Laramie, Wy – The state health department has reported seven cases of the West Nile virus so far in 2008. That's a slower pace than previous years. But Wyoming Department of Health spokeswoman Kim Deti says there's no clear reason why.

We know some things can be a factor like weather or presence of water, but it's difficult to predict from one season to the next what we might encounter or why that might be.

Deti says West Nile has only been present in Wyoming for about five years. That makes it hard to compile good data in such a short time. Deti says that in 2003 nearly 400 cases were reported. West Nile is a mosquito-born disease most common in the summer months.
