Giardiasis is a parasitic diarrheal illness caused by drinking contaminated water1.


Giardiasis is common throughout the world1.


Some people with giardia infection never develop signs or symptoms but still carry the parasite and can spread it to others through their stool. For those who do get sick, signs and symptoms usually appear one to two weeks after exposure and may include diarrhea, fatigue, abdominal cramps and bloating, nausea and weight loss. Symptoms usually last for two to four weeks2.


Giardiasis can be prevented by the provision of clean water and improved sanitation services.
