A new viral disease has been found in Missouri. That’s according to a report out of the current issue of the New England Journal of Medicine. The virus, named the Heartland virus, was first observed in two northwest Missouri farmers. Scott Folk is the Director of Infectious Diseases at Heartland Regional Medical Center in St. Joseph, and is a co-author on the study. He first diagnosed the two farmers with a bacterial disease called erlichiosis, which symptoms include fever, muscle fatigue, headache and nausea.
