AB Cryptosporidium parvum is an important emerging pathogen in the United
States and a cause of severe, life-threatening disease in patients with
AIDS. No safe and effective form of specific treatment for
cryptosporidiosis has been identified to date. The parasite is
transmitted by ingestion of oocysts excreted in the feces of infected
humans or animals. The infection can therefore be transmitted from
person to person through ingestion of contaminated water (drinking water
and water used for recreational purposes) or food, from animal to
person, or by contact with fecally contaminated environmental surfaces.
Outbreaks associated with all of these modes of transmission have been
documented. Patients with human immunodeficiency virus infection should
be made more aware of the many ways that Cryptosporidium species are
transmitted, and they should be given guidance on how to reduce the risk
of exposure. This article summarizes existing data on the various modes
of transmission. It includes an in-depth look at waterborne transmission
because as more research data are made available to the public,
physicians will increasingly be asked by patients about the importance
of this source of infection compared with other sources of infection.
