Scrub Typhus - Presentation
The chigger bite results in a papule, enlarging to a bulla that rapidly sloughs, leaving a shallow ulcer. A black crust surrounded by a 1-2 cm erythematous raised circle then forms (Figure 1). Within 5 days, an unremitting fever to 40 degrees C accompanied by a severe headache is seen in virtually all patients. Generalized lymphadenopathy is the most consistent physical finding, The characteristic rash of scrub typhus is maculopapular & generalized & most prominent on non - exposed skin surfaces. Hepatosplenomegaly and conjunctival injection are common; deafness and tinnitus occur less commonly. Myocarditis and disseminated intravascular coagulation also have been reported.
