Nausea, vomiting, and diarrhea in a 9-year-old girl

Abstract

Cryptosporidiosis is reported in an otherwise healthy child. Her history was significant for playing in natural waters during a camping trip 1 week prior. Several days later, she began improving despite an incorrect diagnosis and inappropriate antibiotic therapy. Nitazoxanide was given once the diagnosis was established. Obtaining a thorough patient history, administering appropriate antibiotics, and counseling patients on preventive measures are critical steps in treating and managing the transmission of this parasite. The case emphasizes the value of stool ova and parasite examination for proper diagnosis of pediatric diarrheal illness in the emergency setting. In addition, the often overlooked diagnosis of cryptosporidiosis is reviewed as an important cause of diarrheal illness in the immunocompetent pediatric population.
