Which method best reduces transmission of plague from fleas to cats?

• A. Flea Control
• B. Vaccination
• C. All Of The Above
• D. Isolation

Answer: (A)

Controlling the flea population is the most effective way to cut transmission because fleas are the direct bridge that passes Yersinia pestis from infected rodents to cats. If fleas are removed or killed on the cat and in the environment, the primary route of infection is interrupted, dramatically lowering the risk to cats.

Vaccination, if available for cats, does not reliably prevent flea bites or infection via fleas, and isolation only reduces exposure but doesn’t eliminate the flea vector in the home or surroundings. So while those measures can help in broader disease management, flea control targets the actual transmission pathway and yields the best reduction in risk.
