The threat of West Nile virus maybe lurking.

West Nile virus is apparently here to stay despite Montana's cool, wet spring, says Montana State University entomologist Greg Johnson.

Most people who suffer severe infection with West Nile virus still experience symptoms years after infection and many may continue to experience these symptoms for the rest of their lives according to research presented today (March 17) at the 2008 International Conference on Emerging Infectious Diseases in Atlanta, Georgia.
