Giardiasis

What is Giardiasis?

Giardiasis is an infectious disease caused by a microscopic parasite known as Giardia lamblia. It is one of the most common intestinal infections in humans, with an estimated 200,000 cases per year in the United States alone. It is commonly spread through food, water, person-to-person contact, and animals such as beavers, muskrats, and dogs.

Signs and Symptoms of Giardiasis

Giardiasis causes a range of symptoms, including abdominal cramping, bloating, gas, diarrhea, nausea, and fatigue. Symptoms usually appear one to two weeks after exposure and can last for several weeks or longer. In some people, symptoms may come and go over a period of months.

Diagnosing Giardiasis

Giardiasis is typically diagnosed through stool and laboratory tests. It is important to seek medical attention if you suspect you may have the infection. An accurate and timely diagnosis is important for proper treatment.

Treatment of Giardiasis

Giardiasis is usually treated with an antibiotic such as metronidazole or tinidazole. The treatment course is typically seven days. In some cases, multiple courses may be necessary. It is important to finish the full course of antibiotics to avoid the potential for relapse.

Preventing Giardiasis

The best way to prevent Giardiasis is to practice good hygiene. This includes washing your hands with soap and water often, especially after using the restroom, changing diapers, or before preparing food. It is also important to avoid swallowing water from lakes and streams. Additionally, sanitizing food preparation surfaces and utensils is another way to reduce the risk of Giardiasis.
