Cryptosporidiosis is a diarrheal disease caused by microscopic parasites of the genus Cryptosporidium. Both the disease and the parasite are commonly known as “Crypto.”
Many species of Cryptosporidium infect humans and a wide range of animals. The parasite is protected by an outer shell that allows it to survive outside the host for long periods of time and makes it resistant to disinfection.
While this parasite can be transmitted in different ways, water is the most common method of transmission. Cryptosporidium is one of the most frequent causes of waterborne disease among people in the United States.
