An Infant with Prolonged Fever.

History: A seven-month-old, developmentally normal girl – born at term with birth weight of 2.5 kg to a nonconsanguineously married couple – presented with fever and rash for 11⁄2 months. The illness started with generalized erythematous, maculopapular rash involving the flexural areas, scalp and trunk, along with intermittent fever. The rash subsided over 15 days leaving behind a dry, scaly skin. During this period, she also developed cough and rapid breathing, and had received intravenous antimicrobials elsewhere with only partial response. The child was referred to our institute in view of reappearance of fever, rash and pedal edema. At admission, she had fever, cough, rapid breathing, poor feeding and irritability, along with dry scaly skin and fading rash. The child was first in birth order with no significant family history of prolonged illness, tuberculosis, or any unexplained death in family. She was immunized for age, and BCG site had a normal scar.
