Question

Which one of the following is not a zoonosis?

1) Cat-scratch disease
2) Hantavirus pulmonary syndrome
3) Rabies
4) Tapeworm
5) None of the above

Answer 1

All the options provided are examples of zoonotic diseases, which means they can be transmitted from animals to humans. Therefore, the answer is option 5) 'None of the above'.

Step-by-step explanation:

Cat-scratch disease, Hantavirus pulmonary syndrome, Rabies, or Tapeworm. Zoonosis is an infectious disease that can be transmitted from animals to humans. Cat-scratch disease is caused by Bartonella henselae and can be introduced to humans through a scratch or bite from a cat. Hantavirus pulmonary syndrome is another zoonotic disease transmitted to humans who inhale air contaminated with the virus from rodent droppings, urine, or saliva. Rabies is a well-known viral zoonotic disease spread through the bites of infected mammals. Tapeworms are parasites that humans can acquire through the ingestion of larvae in undercooked meat from infected animals.

All the diseases listed are indeed zoonoses, so the correct answer would be option 5) 'None of the above'. Each one can be transmitted from animals to humans, therefore, none of the diseases listed fails to be categorized as a zoonotic disease.
