Typhus Rash

This consists of two component parts:

  1. A subcutaneous mottling, of a more or less livid hue, and diffused generally over the body.
  2. Petechiae, small, about the size of pin's heads, scattered all over the body, and showing out from the mottling;  at first these are slightly raised, and their color increases gradually in intensity; they do not fade by pressure, except slightly in the very early stages. The eruption of typhus is not prolonged by successive crops. It makes its appearance between the fifth and eighth day of disease, and disappears a few days before convalescence. It has been mistaken for syphilitic rash.
