Classification

Cryptosporidiosis may be classified as follows:

• Gastrointestinal: In immunocompetent individuals, it primarily presents as a self-limiting diarrhea.
• Extra-gastrointestinal: In immunocompromised individuals, it presents with extra-gastrointestinal manifestations such as:
  • Meningitis
  • Encephalitis
  • Pneumonia
  • Cholecystitis
