Evolutionary genetics underlying the spread of peste des petits ruminants virus

Abstract

Peste des petits ruminants (PPR) constitutes one of the major hurdles to the improvement of small-ruminant production in countries where it is endemic, directly affecting the poor, the main keepers of those species. Despite the existence of highly effective vaccines for more than 25 years, this disease remains a worrying and emerging cause of morbidity and mortality in endemic and high-risk regions of Africa, the Middle East, and Asia.
