MMWR Morb Mortal Wkly Rep. 1994 Dec 2;43(47):876-7.
Hantavirus pulmonary syndrome (HPS) was first recognized in June 1993 as a result of the investigation of a cluster of fatal cases of adult respiratory distress syndrome (ARDS) in the southwestern United States (1). During that month, a 61-year-old man was admitted to a hospital in southern Pennsylvania with ARDS; recent testing of all available specimens from this patient has confirmed the diagnosis of HPS. This report summarizes the case investigation.
