Cryptosporidium is a microscopic parasite that causes diarrheal illness. The parasite is protected by an outer shell which allows it to survive outside of the body for long periods of time. This shell also makes it tolerant to chlorine disinfectant. This parasite can spread many different ways but water transmission is the most common. Cryptosporidium is a leading cause of waterborne disease among humans in the United States.
