Between 1940 and 2004, over 300 emerging Between 1940 and 2004, over 300 emerging disease events were identified in humans around disease events were identified in humans around the world. Concomitantly, other emerging the world. Concomitantly, other emerging infectious diseases also appeared in wildlife, infectious diseases also appeared in wildlife, domesticated animals, and crop and wild plants. domesticated animals, and crop and wild plants. Emerging infectious diseases include those in Emerging infectious diseases include those in which the pathogen has evolved into a new strain which the pathogen has evolved into a new strain within the same host species, for example, within the same host species, for example, through the evolution of drug resistance through the evolution of drug resistance (methicillin-resistant Staphylococcus aureus or (methicillin-resistant Staphylococcus aureus or MRSA) or switched to new host species (for MRSA) or switched to new host species (for example, human immunodeficiency virus or HIV, example, human immunodeficiency virus or HIV, severe acute respiratory syndrome or SARS). In severe acute respiratory syndrome or SARS). In some cases, the switch to new host species is some cases, the switch to new host species is accompanied by a change in geographic range accompanied by a change in geographic range (for example, West Nile virus in the Americas).(for example, West Nile virus in the Americas).
Drivers and locations of emergence events for zoonotic infectious diseases in humans from 1940–2005. a,Worldwide %age of emergence events caused by each driver; b, Countries in which the emergence events took place, and the drivers of emergence. The size of the circle represents the number of emergence events: for scale, the number of events in the United States was 59. Globally, almost half of these diseases resulted from changes in land use, changes in agricultural and other food production practices, or through wildlife hunting, which suggests that contact rates between humans and other animals are an important underlying cause of zoonotic disease emergence. ‘Other’ includes international travel and commerce, changes in human demographics and behaviour, changes in the medical industry, climate and weather, breakdown of public health measures, and unspecified causes.
