27 January 2017, Rome/Paris--- A devastating livestock disease known as Peste des petits ruminants – or PPR for short- has been identified as the reason for a mass die-off of a rare Mongolian antelope. Approximately 900 of these antelopes have been found dead in Mongolia’s western Khovd province. This number represents almost 10 percent of that sub-species’ population. PPR has been known to affect mostly sheep and goats, however this latest outbreak is raising concerns among experts about the evolution of this lethal viral disease.
