Abstract | Peste des petits ruminants virus (PPRV) causes an economically important plague of sheep and goats that serves as a major constraint in the development of the small ruminant’s production within an infected area. The virus is endemic across much of the developing world and has spread into the developed European borders. The small ruminants industry within an infected state or region is often disproportionately affected with its attending impact on poverty in what are already the poorest areas of the globe. PPR is considered to be a transboundary disease of great significance through its effect on the development and maintenance of sustainable agriculture in developing countries, most notably in Western Africa and South Asia. Here, we review, using available data in research papers and reports of international organizations and databases, the factors that enables the spread of PPR in Africa and the required countermeasures that are required to control and eradicate it. However, with challenges such as uncontrolled movement of animals across porous borders, limited financial capacity of farmers to expand or improve the systems, and inadequate supply of quality vaccines and the problem of delivery to maintain cold chain, there is need for a very strong regional coordination for effective and sustainable control of PPR in Africa. The African continent is currently divided into 57 countries (or independent territories), many of which rely heavily on livestock for fuel, motor power and sustenance with many also endemic to the disease. PPRV continues to decimate the small ruminant populations across much of the African countries. Furthermore, given the continued occurrence of PPR and increasing global humans and animals movements,the virus has continued to be reported in previously PPR-free countries and thereby considered as an emerging pathogen.. However, the increased detection of the virus in the light of rinderpest eradication and the lack of awareness of the disease in areas where the virus has been detected for the first time in recent years given the educational status of farmers contributed to this emergence.
