Peste des petits ruminants (PPR) or sheep and goat plague is an acute viral contagious disease caused by a Morbillivirus belonging to the family of Paramyxoviridae affecting primarily sheep and goats and occasionally other species, including endangered wild populations. The disease is present in about 60% of African countries.
The World Animal Health Information System (WAHIS) is used by countries to ensure transparency in the animal disease situation worldwide, including PPR.
The economic impact of PPR in Africa (including production losses and costs for disease control) is estimated at about USD 147 million per year. Eradicating PPR will sustainably improve the resilience of farmers and communities and foster the economic empowerment of women in Africa which are often responsible for such small domesticated animals.
In 2015, World Organization for Animal Health -WOAH (founded as OIE) and the Food and Agriculture Organization of the United Nations (FAO) jointly developed the PPR Global Control and Eradication Strategy, with the objective of eradicating PPR from the globe by 2030. The Strategy includes several tools and components to be implemented through a step-wise approach to decreasing levels of epidemiological risk and increasing levels of prevention and control.
A joint FAO-WOAH Global Secretariat was also established in order to oversee the implementation of the Strategy. The Secretariat organises regional roadmap meetings to facilitate the elaboration and implementation of PPR regional/national action plans in line with the Global Strategy.

PPR is one of the diseases for which WOAH established a procedure for the official recognition of free disease status of Member Countries and the endorsement of an official control programme. Today, six countries in Africa are officially recognised as PPR free (country wide or zonal) :

WOAH International Standards are available (Terrestrial Code and Manual) to guide member countries on how to improve early detection, diagnosis, surveillance, notification, vaccination programmes and better prevent the spread of the disease via international trade in animals and animal products.
Several approaches to the eradication of PPR have been piloted or supported by WOAH in recent years, i.e. the Bill & Melinda Gates Foundation (BMGF) funded “Vaccine Standards and Pilot Approach (VSPA) to peste des petits ruminants (PPR) Control in Africa” which focused on Ghana and Burkina Faso as pilot countries and helped establish WOAH Regional PPR Vaccine Bank (2012 – 2014) and the ongoing World Bank funded Projet Regional d’Appui au Pastoralisme dans le Sahel (PRAPS or Regional Support to Pastoralism in the Sahel project). The project (2015 – 2021) supports PPR vaccinations in Burkina Faso, Chad, Mali, Mauritania, Niger and Senegal.
