Emerging, Re-emerging and Occupational Zoonoses Emerging Zoonoses According to the WHO emerging zoonoses is "a zoonosis that is newly recognized or newly evolved, or that has occurred previously but shows an increase in incidence or expansion in geographical, host or vector range” Re-emerging Zoonoses A re-emerging disease is considered an already known disease that either shifts its Geographical setting or expands its host range, or significantly increases its prevalence. Definition Emerging human pathogens Total human pathogens known Emergence and re-emergence of zoonotic diseases may be any one of the following categories A known agent appearing in a new geographic area.
