How is cryptosporidiosis treated?

Immunocompetent patients (includes children over 5 years old and adults with a health immune system) recover without treatment usually within two weeks. If symptoms persist, nitazoxanide is typically prescribed in the USA. Young children, malnourished children, the elderly, or the immunocompromised (those undergoing organ transplant, advanced HIV/AIDS, etc) may not be able to recover on their own and nitazoxanide has not been show to be effective for this population. In this event, correct diagnosis and care by a physician is critical.
