Giardiasis is a diarrheal disease caused by microscopic parasites called Giardia. These parasites can live in the intestines of many mammals, including humans. Although many species of Giardia are found worldwide, only Giardia Lamblia causes infection in humans. Giardiasis is a common cause of waterborne disease in humans and is sometimes called "beaver fever".
