Giardiasis - Prevention

Alternative Names

Giardia; Traveler's diarrhea - giardiasis

Prevention:

Use a water purification method such as boiling, filtration, or iodine treatment before drinking surface water. Hikers or others who use surface water should consider all sources as potentially contaminated.

Workers in day care centers or institutions should use good handwashing and hygiene techniques when going from child to child or patient to patient.

Safer sexual practices, especially regarding anal sex, may decrease the risk of contracting or spreading giardiasis.
