In ortho-zoonosis there's no developmental change during transmission. It happens by direct contact or by a mechanical vector. e.g. rabies, brucellosis, trichinellosis.
A zoonosis is an animal disease, such as rabies, which can be passed to humans.

Zoonoses
For other zoonotic diseases, programs are in place to eliminate the host, or the vector that spreads the disease. Plague is prevented by elimination of the rats--a common source of the infection--and of fleas that carry the disease from rats to humans.
Other means of prevention simply rely on care. People living in areas where Lyme disease is common are warned to take precautions against the bite of the deer tick, which transfers the disease.
Diagnosis of the disease is made in the usual manner, by identifying the infecting organism. Each disease has established symptoms and tests. Identifying the carrier may be easy, or may be more difficult when the cause is a fairly common infection.
