A parasite is an organism that lives by feeding off another living organism and its nutrients. The most common parasites include tapeworms, hookworms and pinworms.
Overview of Parasitic Infections
•Parasitic infections are more common in rural or developing areas than in developed areas.
•In developed areas, these infections may occur in immigrants, in returning travelers, or in people with a weakened immune system.
•Parasites usually enter the body through the mouth or skin.
•Doctors diagnose the infection by taking samples of blood, stool, urine, phlegm, or other infected tissue and examining or sending them to a laboratory for analysis.
•Travelers to areas where food, drink, and water may be contaminated are advised to cook it, boil it, peel it, or forget it.
•Drugs that eliminate parasites are available for most infections.
