History
Peruvian horse disease was described in 1997 when the number of unexpected deaths on horses occurred during the monsoon season in Peru. The cause of death in most of the affected horses is a complication due to encephalitis. One of the viruses collected from horses that died from the disease was named Peruvian horse disease virus (PHSV). The 1997 outbreak is considered an outbreak of an epidemic involving a variety of domestic animals including horses, cows, donkeys, and sheep. PHSV was also isolated from horses that exhibited similar clinical signs in 1999 in the Northern Territory of Australia, although the Australian isolate was called the Elsey virus until it was determined to be the same species as PHSV.
