Peste des petits ruminants (PPR) is a highly infectious disease of small ruminants and caused by small ruminant morbillivirus (SRMV), formerly called peste-des-petits-ruminants virus (PPRV). This disease is circulating in Africa (except most countries in southern Africa), the Arabian Peninsula, the Middle East, and Central, East and South-East Asia. Peste des petits ruminants is still regarded as an exotic disease in China, where its first outbreak was reported in the Ngari region of Tibet in 2007, but effectively controlled by slaughter, vaccination and animal movement restriction in PPR-infected areas. However, PPR re-emerged in Xinjiang of China in December 2013, rapidly spread into much of China in the first half of 2014, but since then was substantially inhibited countrywide. Phylogenetic analysis shows that SRMVs from China share the highest homology with others from its neighbouring countries, possibly indicating the transboundary transmission of SRMVs. In 2015, a national eradication program for PPR was issued and has been being implemented in China, expecting to achieve a PPR-eradicating aim countrywide by 2020. Here, we reviewed a 10-year history (2007-2017) of PPR in China, including two major outbreaks, its infection in wild species, development of diagnostics and vaccines, and implementation of the national eradication program.
