Febrile rash and convalescent rash of dengue fever.

A 9-year-old girl presented with fever for 4 days. On day 8 of illness, when her fever subsided, she developed hypotension. Her platelet count dropped to 15000/ml and hematocrit increased to 42.8%. She was resuscitated with fluid boluses. She developed typical dengue rash of convalescence 3 days after defervescence (Fig. 2). Her dengue serology IgM and IgG were positive, suggestive of secondary dengue infection.
