Cryptosporidiosis (cryp·to·spo·ri·di·o·sis)
Click to View Cryptosporidiosis Life Cycle  Adobe PDF Document

Cryptosporidiosis is transmitted by the fecal-oral route (for example, swallowing contaminated recreational/untreated water, eating raw or undercooked contaminated food) by ingestion of cysts of the parasite Cryptosporidium parvum. The usual incubation period is 2-10 days with typical symptoms of watery diarrhea, abdominal cramps, and low-grade fever; however, asymptomatic infection is also common. The symptoms last up to 2 weeks in healthy individuals. Those who have a weakened immune system may experience prolonged illness.

Immunocompromised individuals (e.g., HIV/AIDS patients, cancer patients, transplant patients), young children and pregnant women are at risk for more severe illness.
