Can you get sick from flee bites?

Flea. I agree with dr. Guzik. Fleas can carry tapeworms & murine typhus. In some parts of the world to include the southwestern United States they can carry a bacteria called yersinia pestis which can cause bubonic plague.
Yes. Diseases transmitted by fleas in addition to delivering annoying, itchy bites, fleas are capable of transmitting infectious diseases either by direct transmission or by acting as a vector for disease producing organisms. Skin bite dermatitis, typhus, and even plague can occur.
