Giardia is a simple organism, but it is infectious when even a few protozoa are ingested. In the U.S., Giardia is frequently the most common cause of waterborne diarrhea. This protozoa has been found in about 80% of raw water supplies from streams, lakes, ponds, rivers and mountain water. Giardia is usually acquired through ingestion of either contaminated water or food or via person-to-person contact (fecal matter). Giardiasis is a mild infectious disorder, but a few patients may present with abrupt explosive watery diarrhea, abdominal cramps, foul-smelling stools, fever, vomiting and general malaise. Once Giardia infection is diagnosed, most can be treated as outpatients. People at the highest risk of acquiring this organism include travelers, campers, children, men who have sex with men and those with immunodeficiency syndromes.


The goal of this Giardia continuing education program is to provide healthcare professionals, specifically pharmacists, dietitians, and health educators, with information about Giardia and the epidemiology, presentation and management of the infection. After studying the material presented here, you should be able to:
  • Describe Giardia, its epidemiology and clinical presentation
  • Review the different approaches to identifying the organism
  • Discuss treatment options open to the healthcare professional team and the drugs available to treat Giardia infections
