Peste des petits ruminants (PPR) is a highly infectious transboundary animal disease that affects mainly sheep, goats, and small wild ruminants. This disease, caused by the peste des petits ruminants virus (PPRV), a virus of the Morbillivirus genus within the Paramyxoviridae family, is characterized clinically by ocular and nasal discharges, diarrhea, and erosive lesions of different mucous membranes. All these symptoms are similar to those of rinderpest (RP) that has recently been eradicated worldwide. An important distinguishing symptom that is found in acute PPR but which is absent in RP is bronchopneumonia. With morbidity and mortality rates that can be as high as 70%–80%, PPR is classified within the group of animal diseases that are notifiable to the Office International des Epizooties (OIE), the World Organization for Animal Health. It is considered as the main small ruminant disease in countries where it is endemic. Sheep and particularly goats (which are known as the cattle of the poor) contribute considerably to the cash income and nutrition of small farmers. So the control of a disease such as PPR, which is the main killer of those animals, is considered as an essential element in the fight for global food security and poverty alleviation.
