Macaque malaria in long-tailed macaques and humans in Southeast Asia. The number of human P. knowlesi cases that have originated from the location is represented in shades of grey. The maximum range of Macaca fascicularis [50] is greater than the extent of known P. knowlesi spillover cases. Pie charts depict cumulative results of parasitological and molecular surveys of malaria (all five Plasmodium species) in long-tailed macaques, with the size of the circle corresponding to sample size from the given location.
