What are Zoonoses?

Zoonoses are diseases or infections which are naturally transmissible from vertebrate animals to man (World Health Organisation). Over 200 zoonoses have been described.

Examples include: Bacteria (Salmonellosis, campylobacteriosis, e. coli, anthrax, brucellosis, leptospirosis, plague, shigellosis and tularaemia); Parasites (Toxoplasmosis, cysticercosis/taeniasis, echinococcosis/hydatidosis and trematodosis); Rickettsial Diseases (Q-fever); Viruses (Rabies, avian influenza, Crimean-congo hemorrhagic fever, ebola and rift valley fever); Unconventional Agents: Bovine Spongiform Encephalopathy(BSE)

Emerging zoonoses are zoonoses that are newly recognized or newly evolved, or that have occurred previously but show an increase in incidence or expansion in geographical, host or vector ranges. Examples include avian influenza, BSE and the Nipah virus.
