Giardiasis is one of the most common causes of waterborne diseases which is characterized by watery diarrhea, abdominal cramps, bloating, nausea and weight loss. Though sometimes people don’t develop the symptoms for several days even after getting the infection. Giardia parasites are found in the ponds, rivers, lakes, water parks and municipal water supplies. Surface water and ground water get contaminated with the waste water and fecal matters. Most common cause of giardiasis is the consumption of the contaminated water. Giardiasis parasites can also be transmitted by eating food which is prepared under the unhygienic conditions. Giardiasis infection may also spread if your hands, fingers, and nails are contaminated with fecal matter. Complications associated with Giardiasis:- 1.
