lambliasis

Giardiasis, also known as lambliasis, is an intestinal illness caused by a microscopic parasite called Giardia duodenalis (also known as Giardia lamblia or Giardia intestinalis). This parasite is found throughout the world, particularly in areas with poor sanitation. It is transmitted through the fecal-oral route, meaning it spreads when someone ingests Giardia cysts from the feces of an infected person or animal. This can happen by drinking contaminated water, eating contaminated food, or by direct contact with an infected person or animal.

Many people infected with Giardia do not show symptoms. However, when symptoms do occur, they typically begin one to two weeks after infection and can include diarrhea, gas, greasy stools, stomach cramps or pain, nausea, and dehydration. Symptoms can last for several weeks. Diagnosis is usually made by examining a stool sample for the presence of Giardia cysts or trophozoites.

Treatment for giardiasis is typically with antiparasitic medications prescribed by a healthcare provider. Preventing giardiasis involves practicing good hygiene, such as frequent handwashing, especially after using the toilet or changing diapers, and before preparing or eating food. It also includes drinking safe, treated water and thoroughly washing fruits and vegetables. In areas where water quality is questionable, boiling water or using water filters is recommended.
