Laboratory Diagnosis of Tick-Borne Infections

Patient Case 1

July 2010

The first case is of a 75 year-old male from Wabasha, MN who presents to his local emergency department with a fever and shortness of breath. The patient works as a deer processor and 2 weeks prior to presentation had returned from a hunting trip in Wisconsin. Laboratory results reveal that the patient is thrombocytopenic and leukopenic, and he subsequently develops progressive respiratory distress. Because of his deteriorating status, the patient is intubated and transferred to the intensive care unit.
