How is the disease contracted?
Cryptosporidium lives in the intestine of infected humans or animals. Millions of Crypto germs can be released in a bowel movement from an infected human or animal. Consequently, Cryptosporidium is found in soil, food, water, or surfaces that have been contaminated with infected human or animal feces. If a person swallows the parasite they become infected. You cannot become infected through contact with blood.
