Abstract:

Giardia lamblia is a zoonotic parasite worldwide and infection with the genus G. lamblia may cause giardiasis, with diarrhea and abdominal pain as main clinical symptoms. Giardiasis poses a serious threat to health among children and immunocompromised individuals. Because of limited treatment options and no clinically available vaccines, giardiasis has been paid more and more attention across the world. This review summarizes G. lamblia human infections since the first record of giardiasis in 1924 and waterborne and foodborne contaminations in China, so as to provide insights into formulation of the human giardiasis control strategy in China.

Key words: Giardia lamblia, Giardiasis, Human, Waterborne, Foodborne
