How can I prevent giardiasis?
There is no vaccine for giardia. If you are traveling to an area where giardiasis is common, make sure to drink bottled water or boil the water and do not drink drinks with ice cubes. Careful hand washing can help prevent giardia, especially after going to the bathroom and before preparing food. If you are swimming, follow proper swimming hygiene. Do not swim until 7 days after your diarrhea has stopped and shower before swimming.
