Notes on Meaning

• Distinction from Other Typhus Types: It is critical to distinguish "rat typhus" from other forms. "Epidemic typhus" (louse-borne) is often more severe and is associated with human body lice, not fleas. "Scrub typhus" is transmitted by chiggers (mite larvae).
  • While both are serious, rat typhus is generally less severe than epidemic typhus.
