Peste des petits ruminants in China: Spatial risk analysis.

During the period spanning November 2013 to November 2018, 294 outbreak cases of PPR were diagnosed. Spatio-temporal cluster analysis was performed to determine whether or not areas and time periods with significant aggregation of PPR outbreaks occurred. High-risk areas for PPR outbreaks in China were detected using the presence-only maximum entropy ecological niche model. The analysis identified three statistically significant disease clusters. Precipitation of driest month was identified as the most important predictor for PPRV occurrence.
