The impact of human population pressure on flying fox niches and the potential consequences for Hendra virus spillover

Abstract Hendra virus (HeV) is an emerging pathogen of concern in Australia given its ability to spillover from its reservoir host, pteropid bats, to horses and further on to humans, and the severe clinical presentation typical in these latter incidental hosts. Specific human pressures over recent d...
