Prevention

Practice good hygiene in day care centers, retirement homes, and at home to prevent the spread of giardiasis infection. Wash your hands often, and avoid contact with the stool (feces) of an infected person.

Do not use untreated water in areas where the giardia parasite may be present. To prevent the spread of giardiasis from contaminated water, boil the water before you use it. Also, be sure swimming pools are properly treated and have proper filtration systems.

Prevent infection when traveling to areas where the water may contain Giardia by using only bottled water, avoiding raw fruits and vegetables, and not drinking beverages containing ice cubes.
