Murine Typhus (Fleaborne Typhus)

Flea-borne (also known as “murine” or “endemic”) typhus is a rickettsial disease caused by Rickettsia typhi, or possibly R. felis, bacteria that can be transmitted by infected fleas harbored by rats, opossums, cats, dogs and other small mammals. The disease is similar to louse-borne typhus (R. prowazekii) but is generally milder. Disease onset is often sudden, and symptoms may include fever, headache, chills, weakness, nausea/vomiting, body aches, and rash. Flea-borne typhus can be a serious disease, especially if diagnosis and treatment are delayed, and may result in hospitalization. In the United States, Texas reports the highest numbers of flea-borne typhus cases annually, with the southernmost portion of the state being considered endemic.
