Globally, urbanization is accelerating, with 2 different of the world's population predicted to live in cities over the next 30 years. Although cities are well-known for their significance in human infectious illness, little is known about how urban environments impact wildlife pathogen interaction. Humans use recent developments in wild-life epidemiology to investigate how urbanization affects the biology of hosts, diseases, or vectors. Although urbanization lowers the number among several wildlife parasites, the transmission may rise among urban-adapted hosts in certain instances, having an impact on rarer animals or those that live beyond city borders. Continued growing urbanization, along with the dangers presented by multi-host infections to people and fragile wildlife species, highlights the need for further study into wildlife illnesses in urban environments.
