Name a zoonotic disease.

• A. Canine Parvovirus
• B. Lepto
• C. Canine Distemper
• D. Canine Influenza

Answer: (B)

Zoonotic transmission is when a disease can pass from animals to humans. Leptospirosis is a classic example because it’s caused by Leptospira bacteria carried by many animals, including dogs, and shed in their urine. Humans can become infected by contact with urine or water, soil, or surfaces contaminated by that urine, especially in outdoor or wet environments. This makes Leptospirosis a real risk to people who are around dogs or who work outdoors, and it’s important to prevent exposure through vaccination of dogs where available, avoiding contact with potentially contaminated water, and using protective measures if handling urine or cleaning areas exposed to it. In dogs, the infection can affect kidneys and liver, so veterinary vaccination and prompt treatment help protect both the animal and the people who care for it.

The other diseases listed are not typically zoonotic. Canine Parvovirus mainly affects dogs and is not known to spread to humans in ordinary circumstances. Canine Distemper is a canine virus that does not infect humans. Canine influenza affects dogs, and while human infections with animal influenza strains can occur in rare cases, it is not considered a common dog-to-human zoonosis.
