The order Chiroptera is the second largest order of mammals and shows great physiological and ecological diversity. These animals play significant ecological roles as prey and predator as well as facilitating pollination, seed dispersal, arthropod reduction and nutrient distribution and reutilisation in nature. Bats act as hosts to a range of viral, bacterial, fungal and parasitic zoonoses. Human activities increase the likelihood of exposure to bats, thereby increasing the opportunity for infections to spill over. Continuing ecological processes, emergence and spillover of novel pathogens in naïve hosts, including humans, along with other complex natural phenomena require proper understanding that may help in predicting the next spillover. This review will discuss the ecology of bats and their role in the emergence of different zoonoses, particularly those of viral origin, in an organised manner to increase understanding of the factors that may play significant roles in spillover of these pathogens from bats to other animals, including humans.
