Hantavirus pulmonary syndrome (HPS) is an acute respiratory disease caused by the Sin Nombre virus. The disease was first described as a clinical syndrome and the causative agent identified as the Sin Nombre virus in the Four Corners area (Utah, New Mexico, Colorado, Arizona) in 1993. Most cases have been reported from states west of the Mississippi River. However, 12 states east of the Mississippi have reported cases, including Indiana. Since 1993, two cases (one during the five-year period 1998-2002) have been reported in Indiana, resulting in one death. Nationally, 36 percent of all reported cases of hantavirus have resulted in death.
No hantavirus cases were reported in Indiana in 2002.
