A similar confusion exists for the term zooanthroponosis. I choose to ignore such confusing definitions. This term also ignores the phylum to which the non-human animal belongs. I feel this is a mistake because it implies to the uninitiated that the insects involved only serve as a simple transportation vehicle for the infectious agent. However, in many cases, such as for the above mentioned malaria, the mosquito is a true, infected host .
Some authors define zoonosis as trans-species transmission between animal species.
They therefore consider the transmission between humans and other animals as only one type of zoonosis. Again, no definition is wrong and no definition is right . They are just different ways of viewing the same phenomenon. I will stick to my definition. A Zoonosis is Not A Zoonosis is NOT an infection where the same infectious agent can infect humans and other animals, but where there is no transmission between humans and the other animals .
