Causes, incidence, and risk factors:

Cryptosporidium has recently been recognized as a worldwide cause of diarrhea in all age groups -- yet its major impact has been among individuals with weakened immune systems (including people with HIV or AIDS) and transplant recipients. In such people, this diarrheal infection is not just bothersome but can lead to severe and potentially life-threatening wasting and malnutrition.

The major risk factor is ingestion of fecally contaminated water. Young children, animal handlers, people with close contacts of infected individuals, and men who have sex with men are at higher risk.

Outbreaks have been linked to drinking from contaminated public water supplies, drinking unpasteurized cider, and swimming in contaminated pools and lakes.
