Often share common themes: environment disruption by humans, exposure of mi different niche that selects for new virulence traits and facilitates transmission to genetic changes that then allow transmission to humans. Emerging disease: disease occurring in a new geographic area, rapidly exp incidence, displaying novel genetic code or moving into humans for the first.
