Discussion Cryptosporidium is an oocyte-forming coccidian protozoan. It is transmitted through ingestion of contaminated food, water, or contact with infected persons or animals (particularly preweaned calves). It is a common cause of diarrhea from contaminated recreational water supplies including lakes, ponds, streams, and pool and waterpark water. It has been associated with occupational exposures in agricultural settings and veterinary schools. Emergencies where calves or biological samples are involved have caused transmission of Cryptosporium to first responders. Others at risk include young children and those who care for them (i.e. parents, child care professionals), swimmers who swallow contaminated water, those exposed to human feces through sexual contact, and domestic and international travelers. Travelers who drink unfiltered, untreated water are at higher risk. People who are immunocompromised are also at higher risk. The most common symptom is watery diarrhea that begins about 7-10 days (range 2-26 days) after infection and is self-limited. Excretion can be intermittent and last for weeks. Other symptoms are abdominal cramps, decreased appetite and weight loss, emesis, fever, fatigue, headache and joint pain.

Multiple stool samples may be needed because of the intermittent excretion. Immunocompetent patients are usually not tre...
