The disease can cause symptoms ranging from those similar to the flu to renal failure and difficulty breathing.

The man's family says he found an attached tick after a fishing trip in northeast Missouri. He was hospitalized and given antibiotics, but his condition deteriorated rapidly.

The case was one of nine cases of tick-borne diseases reported recently.
