Zoonoses refers to

Zoonoses refers to

• A. Diseases transmitted from humans to animals
• B. Diseases transmitted from animals to the environment
• C. Diseases transmitted from animals to humans
• D. Diseases prevented by vaccines

Answer: (C)

Zoonoses are diseases that can be transmitted from animals to humans. The key idea is the direction of transmission: pathogens pass from animal hosts or vectors to people, through contact, bites, inhalation of aerosols, or consumption of contaminated animal products. This distinguishes zoonoses from infections that move from humans to animals (reverse zoonosis) or from diseases that involve the environment as the primary bridge without an animal source. Vaccination status isn’t what defines a zoonosis—some zoonotic diseases have vaccines and some do not. Examples include rabies from animal bites, Salmonella from contaminated animal products, and Lyme disease transmitted by ticks that feed on animals.
