Which diseases can fleas spread through bites?

Fleas are known vectors for several diseases due to their biting behavior and ability to transmit pathogens. Murine Typhus, caused by the bacterium Rickettsia typhi, is commonly associated with fleas, particularly in urban environments where rodent infestations occur. Fleas can carry the bacteria from rodents to humans, facilitating the spread of this disease.

Cat Scratch Fever, on the other hand, is caused by the bacterium Bartonella henselae, which can be transmitted to humans through flea bites as well. Fleas that infest cats can harbor this bacterium and, when they bite humans, can lead to the infection.

Both of these diseases emphasize the significant health risks posed by flea infestations, particularly in environments where pets and rodents coexist. Therefore, the choice highlighting Murine Typhus and Cat Scratch Fever accurately reflects the diseases transmitted by flea bites.
