Plasmodium vivax is the most prevalent malarial species in South America and exerts a substantial burden on the populations it affects . The control and eventual elimination of P . vivax are global health priorities . Genomic research contributes to this objective by improving our understanding of the biology of P . vi... | Although P . vivax is not as deadly as the more widely studied P . falciparum , it remains a pressing global health problem . Here we report the results of a whole-genome study of P . vivax from Cordóba , Colombia , in South America . This parasite is the most prevalent in this region . We show that the parasite popula... | [

In order to investigate how the movement of dogs affects the geographically inter-provincial spread of rabies in Mainland China , we propose a multi-patch model to describe the transmission dynamics of rabies between dogs and humans , in which each province is regarded as a patch . In each patch the submodel consists o... | In 1999 , human rabies cases were reported in about 120 counties in Mainland China , mainly in the southern provinces . Now outbreaks of human rabies have been reported in about 1000 counties and the disease has spread geographically from the south to the north .
