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 coloration back with seaweed, sponges and stones. In variable protective resemblance, an animal such as a chameleon, flatfish, squid or octopus changes its skin pattern and colour using special chromatophore cells to resemble whatever background it is currently resting on (as well as for signalling). The main mechanisms to create the resemblances described by Poulton – whether in nature or in military applications – are crypsis, blending into the background so as to become hard to see (this covers both special and general resemblance); disruptive patterning, using colour and pattern to break up the animal's outline, which relates mainly to general
