Flea-borne Typhus, (Murine Typhus, Endemic Typhus)

Flea-borne (also known as “murine” or “endemic”) typhus is a rickettsial disease caused by Rickettsia typhi. Infected fleas carried by rats, opossums, cats, dogs, and other small mammals can spread these bacteria. The disease is like 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 and can result in hospitalization. This is more likely with delayed diagnosis and treatment.
