Researchers have solved part of a medical mystery about a new virus that infected two Missouri men in 2009, confirming the pathogen in lone star ticks near where the patients were infected, then hospitalized, after they were bitten by ticks, according to a study today. The hunt for the tick that possibly carried the new Heartland virus included collecting 56,428 ticks by combing through brush with flannel pads mounted on bamboo poles, using carbon dioxide-emitting dry ice to lure ticks into plastic containers, and plucking the insects from horses and dogs.
