Ovine rinderpest virus does not infect humans. This disease was first described in 1942 in Côte d'Ivoire. Now, PPR has spread to more than 70 countries in the world. In 2017, the disease was reported to be affecting saiga in Mongolia, causing near-catastrophic herd depletion for the endangered species. In 2018, the disease was reported to be in Bulgaria close to the border with Turkey. PPR is also known as goat plague, "kata", syndrome of stomatitis-pneumoenteritis, and ovine rinderpest. Official agencies such as the FAO and OIE use the French name ""peste des petits ruminants"" with several spelling variants. Symptoms are similar

Animal rights organizations—such as PETA and BUAV—question the need for and legitimacy of animal testing, arguing that it is cruel and poorly regulated, that medical progress is actually held back by misleading animal models that cannot reliably predict effects
