• A. True
• B. False
• C. Not sure
• D. Cannot determine

Answer: (A)

Zoonotic diseases are infections that originate in animals and can be transmitted to humans. This transmission can occur through direct contact with animals (such as bites or handling), exposure to contaminated animal products or environments, or via vectors like ticks and mosquitoes that acquire the pathogen from animals. Examples include rabies from animal bites, salmonellosis from contaminated animal foods or contact with animals, hantavirus from rodent excreta, and avian influenza from birds. While some zoonoses can later spread between humans, the defining point is that the disease comes from an animal source and can reach humans. So the statement is true.
