Overview: A zoonosis is any disease or infection naturally transmissible from vertebrate animals to humans and vice versa. Humans are often an incidental host that acquire disease through close contact with an infected animal that may or may not be symptomatic.
More than 200 zoonoses of various types are recognised worldwide. They can be caused by a range of disease-causing agents such as viruses, bacteria and many more. Of 1 415 disease-causing agents known to infect humans, 61% are zoonotic. Statistical data indicate that 15% or more of the human population will pick up a zoonotic infection at some stage of their lives.
Zoonoses also undermine the health, productivity and reproductivity of livestock on which humans rely for their food, fibre, labour and transport. The annual worldwide monetary losses due to tuberculosis, brucellosis and rabies in cattle amount to several billion rand.
