Which statement correctly differentiates anthropozoonoses from zooanthroponoses?

• A. Zooanthroponoses: disease from people to animals.
• B. Anthropozoonoses: disease from animal to people.
• C. Anthropozoonoses: disease from environment to humans.
• D. Zooanthroponoses: disease from animals to people.

Answer: (B)

The essential idea here is the direction of transmission between humans and animals. Anthropozoonosis refers to infections that originate in animals and can be transmitted to humans (animal-to-human transmission). This is sometimes described as a reverse-zoonosis. An example is rabies, which is transmitted from animals to people.

Zooanthroponosis, on the other hand, describes infections that originate in humans and can be transmitted to animals (human-to-animal transmission). So when differentiating the two, the statement that correctly characterizes anthropozoonosis is that it involves disease transmitted from animals to people. The other options mix up the direction or attribute the direction to the wrong term.
