etiology and epidemiology of the four corners hantavirus may and june 1993, a handful of previously healthy residents of rural areas in the four corners region of the southwestern united states died of acute unexplained respiratory distress, later diagnosed as hantavirus pulmonary syndrome. their illnesses were characterized most prominently by a prodrome of fever and myalgias, followed by thrombocytopenia, the presence of immature white blood cells on the peripheral smear, and catastrophic respiratory decline associated with the sudden onset of no ...19947866656
