Giardia "Beaver Fever:" causes, symptoms and how water purifier bottles can protect you.

Paul Connolly
Giardia duodenalis (pronounced "gee-ar-dee-uh doo-oh-den-al-is") is a microscopic parasite that causes a diarrheal disease called giardiasis, also known as "beaver fever." It spreads easily through contaminated water sources like lakes, rivers, and poorly treated water supplies - making it a concern for hikers, campers, and travelers, especially in developing countries like Mexico where giardia infections are more common.
