Missouri is home to a new virus. CDC scientists say they discovered the newly-named Heartland Virus in the state's adult tick population. About one in 500 ticks tested carried the disease, which causes fever, chills, aches, nausea and diarrhea. There's no treatment for the virus but the two men who became infected recovered after about two weeks in the hospital.
Scientists say they don't know how the disease will spread and its discovery makes it even more important to scan your body for the critters after going outside. Missouri leads the country in diseases that come from ticks.
