Which disease is transmitted by fleas from rodents?

• A. The respiratory droplets
• B. Direct contact with infected tissue
• C. Contaminated water
• D. Bubonic plague is transmitted by fleas from rodents

Answer: (D)

Flea-borne transmission from rodents is a classic vector-borne disease scenario. Rodents harbor Yersinia pestis, and fleas that feed on these infected rodents pick up the bacteria. When those same fleas bite humans, they can inject the bacteria into the skin, leading to bubonic plague. The hallmark is transmission by a flea bite rather than by coughing, water, or direct contact with tissue. Other transmission routes described fit different diseases and contexts, not the rodent-flea pathway that drives bubonic plague. So the disease linked to fleas from rodents is bubonic plague.
