Flea-Borne Typhus, also known as Endemic or Murine Typhus, is a bacterial infection caused by Rickettsia typhi. It's primarily spread to humans through infected flea bites, often from fleas on rodents like rats. It occurs globally in areas with poor sanitation and rodent populations, especially in tropical and subtropical regions.

Flea-Borne Typhus was historically often confused with Epidemic Typhus due to similar symptoms. Its distinct identity, linked to rodents and fleas, was recognized in the early 20th century, with the causative agent *Rickettsia typhi* identified in 1928. Its understanding helped differentiate various rickettsial diseases and their specific transmission cycles.
The disease is primarily transmitted when infected rat fleas (*Xenopsylla cheopis*) bite humans. Fleas become infected by feeding on rodents (like rats, opossums, or cats) that carry the *Rickettsia typhi* bacteria. Transmission usually occurs when flea feces, containing the bacteria, are scratched into the bite wound or other breaks in the skin, or by inhaling aerosolized flea feces.
