Peste des Petits Ruminants Viruses Re-emerging in China, 2013-2014.

Re-emergence of peste des petits ruminants (PPR) was officially reported in Xinjiang Uygur Autonomous Region in north-western China in November 2013, and then along with the movements of goats and sheep, this disease rapidly spread to other provinces, autonomous regions and municipalities (P/A/M) of China. A total of 256 PPR-affected counties in 22 P/A/M were identified up to September 2014. Phylogenetic analysis revealed that the current circulating strains and Tibet strains isolated previously in 2007, both belonged to lineage IV but in different sub-branches. Nevertheless, compared with the Tibet strains, the current circulating strains shared high degree of genetic homology with those from Pakistan and Tajikistan.
