    Global Strategy for the Control and Eradication of PPR 2015
    Also available in:

    Peste des petits ruminants (PPR) is a highly contagious disease of sheep and goats caused by a Morbillivirus closely related to rinderpest virus and is considered to be one of the most damaging livestock diseases in Africa, the Middle East and Asia. Bearing in mind the strong negative impact that PPR can have on food security and the livelihoods of poor farmers, the main keepers of sheep and goats, the Global Framework for the Progressive Control of Transboundary Animal Diseases (GF-TADs) Global Steering Committee in 2012, the Food and Agriculture Organization of the United Nations’ (FAO) Council and the Committee on Agriculture (COAG) and the World Organisation for Animal Health (OIE), in the form of a Resolution of the World Assembly of Delegates of the OIE in 2014, have all recommended the development of a PPR Global Control and Eradication Strategy (hereinafter named ‘Global Strategy’) and expressed a strong willingness to address the animal health problems in a systematic way, dea ling with horizontal as well as more disease-specific (vertical) issues.

    Peste des Petits Ruminants Virus Infection at the Wildlife–Livestock Interface in the Greater Serengeti Ecosystem, 2015–2019 2021

    Peste des petits ruminants (PPR) is a viral disease of goats and sheep that occurs in Africa, the Middle East and Asia with a severe impact on livelihoods and livestock trade. Many wild artiodactyls are susceptible to PPR virus (PPRV) infection, and some outbreaks have threatened endangered wild populations. The role of wild species in PPRV epidemiology is unclear, which is a knowledge gap for the Global Strategy for the Control and Eradication of PPR. These studies aimed to investigate PPRV infection in wild artiodactyls in the Greater Serengeti and Amboseli ecosystems of Kenya and Tanzania. Out of 132 animals purposively sampled in 2015–2016, 19.7% were PPRV seropositive by ID Screen PPR competition enzyme-linked immunosorbent assay (cELISA; IDvet, France) from the following species: African buffalo, wildebeest, topi, kongoni, Grant’s gazelle, impala, Thomson’s gazelle, warthog and gerenuk, while waterbuck and lesser kudu were seronegative. In 2018–2019, a cross-sectional survey of randomly selected African buffalo and Grant’s gazelle herds was conducted. The weighted estimate of PPRV seroprevalence was 12.0% out of 191 African buffalo and 1.1% out of 139 Grant’s gazelles. All ocular and nasal swabs and faeces were negative by PPRV real-time reverse transcription-polymerase chain reaction (RT-qPCR). Investigations of a PPR-like disease in sheep and goats confirmed PPRV circulation in the area by rapid detection test and/or RT-qPCR. These results demonstrated serological evidence of PPRV infection in wild artiodactyl species at the wildlife–livestock interface in this ecosystem where PPRV is endemic in domestic small ruminants. Exposure to PPRV could be via spillover from infected small ruminants or from transmission between wild animals, while the relatively low seroprevalence suggests that sustained transmission is unlikely. Further studies of other major wild artiodactyls in this ecosystem are required, such as impala, Thomson’s gazelle and wildebeest.

    Peste des Petits Ruminants Eradication - Advancing the eradication of Peste des Petits Ruminants (PPR) in Africa 2019

    Peste des petits ruminants (PPR) is a highly contagious disease infecting wild and domestic small ruminants, which was first reported in 1942 in Côte d’Ivoire. Some 5.4 billion people live in affected areas, the majority of them among the world’s poorest livestock farmers. This disease is particularly relevant for Africa, where 33.8 percent of global small ruminants are reared. Thankfully, PPR is readily diagnosed and a reliable, inexpensive and high-quality vaccine is available to immunize animals. FAO and OIE began a global coordinated effort in 2015 to wipe out the disease by 2030. Stepping up this initiative will advance the PPR global eradication programme in Africa and ensure coordinated implementation.
