Ovine rinderpest
（重定向自Peste des petits ruminants）
Ovine rinderpest, also commonly known as peste des petits ruminants (PPR), is a contagious disease affecting goats and sheep in Africa (from the Tropic of Cancer to the Equator), the Middle East and the Indian subcontinent. But since June 2008, the disease invaded Morocco, which indicates a crossing of the natural barrier of the Sahara. It is caused by a species of the Morbillivirus genus of viruses. The disease is highly contagious, and has roughly an 80 percent mortality rate in acute cases.
