Drinking Water Fact Sheet: Cryptosporidium
Cryptosporidium parvum (C. parvum) is a protozoan parasite known to infect humans and many animal species. The infective oocysts of Cryptosporidium are shed in the feces, and infection can occur by consumption of contaminated food or water, ingestion of contaminated recreational water, or through contact with feces of infected persons or animals. Cryptosporidium is not new, but is has gained recognition, both because it has become more widespread and because of evidence that there are potential life-threatening consequences of infection in the growing population of immunocompromised persons.
