As an example of “I don’t really want to know, but I just can’t look away,” this website by the Center for Disease Control’s Division of Parasitic Diseases (DPD) is an excellent place to learn exactly how many different organisms want to lay siege to your body. (Sometimes, ignorance can be bliss.) One can read about these conspiring critters (life cycle diagrams included!) under the “Parasites and Health” tab, which covers parasites of the intestinal tract, blood-borne parasites, and parasites found in other sites. There is an image gallery as well as a great diagnostic procedures reference. Aimed toward assisting healthcare professionals to reach fast and accurate diagnoses of parasites, DPDx is a well organized, concise, and useful online resource that is accessible to laypeople and healthcare professionals alike.
