Cryptosporidium (crip-toe-spor-ID-ee-um) is a protozoan, a single-celled parasite that lives in the intestines of animals and people.
Unlike Plasmodium, which transmits via a mosquito vector, Cryptosporidium does not use an insect vector, and is capable of completing its lifecycle within a single host, resulting in cyst stages that are excreted in feces or through coughing fomites and are capable of transmission to a new host.
