In areas where peste des petits ruminants (PPR) is endemic, most rinderpest-like syndromes are more likely to be PPR. Peste des Petits Ruminants (PPR), also known as Goat Plague and Ovine Rinderpest, occurs in goats, sheep and related species. Peste des petits ruminants (PPR) is an acute to sub-acute highly contagious and frequently fatal viral disease of goats and sheep and wild small ruminants caused by a virus in the genus morbilivirus, family paramyxoviridae.
