giardiasi

Giardiasis is a parasitic infection caused by the protozoan Giardia lamblia. It is primarily transmitted through the ingestion of contaminated water or food, or through person-to-person contact. Giardia is a flagellated protozoan, meaning it has whip-like structures that help it move. It is found in the small intestine and can cause symptoms such as diarrhea, abdominal cramps, bloating, and nausea. The infection is typically self-limiting and resolves within a few days to two weeks without treatment. However, in some cases, it can lead to more severe complications, such as malabsorption of nutrients, which may require medical intervention. Giardiasis is more common in areas with poor sanitation and hygiene, but it can occur anywhere. Prevention involves maintaining good hygiene practices, such as washing hands thoroughly, avoiding drinking untreated water, and cooking food properly. Treatment options include antiparasitic medications, such as metronidazole or tinidazole, which are effective in clearing the infection.
