Scrub typhus | About 25–50% of scrub typhus patients develop a rash. The rash is usually macular or maculopapular. Typically, it will begin on the abdomen of an infected individual and then spread to the extremities. Petechiae are uncommon |
Murine Typhus | The rash typically occurs at the end of the first week of the illness and lasts 1–4 days. It generally starts as a maculopapular eruption on the trunk and spreads peripherally, sparing the palms of the hands and soles of the feet. Rash may vary among individuals, or may be absent altogether and should not be relied upon for diagnosis. |
Epidemic Typhus | The rash usually begins a couple of days after the onset of symptoms. It typically begins as a maculopapular eruption on the trunk of the body and spreads to the extremities, usually sparing the palms of hands and soles of feet. When the disease is severe, petechiae may develop. The rash may be variable among individuals and stage of infection, or may be absent altogether and should not be relied upon for diagnosis |
