Giardiasis is an infectious diarrheal disease. It is caused by a parasite, Giardia lamblia, that is most commonly transmitted through oral-fecal contact and by water contaminated by feces, such as in sanitary sewers.
Symptoms Take about 1 to 2 weeks to show themselves and include : 1: Explosive loose stool (diarrhea) 2: Abdominal Pain 3: Bloating 4: Excessive gas 5: Blood in the mucus or stool
Occasionally the symptoms may last for months, or even years! Causing reoccuring symptoms including, impaired digestion, sygnifigat weight loss, tiredness or weakness, and diarrhea.
Giardiasis is sometimes overlooked because the symptoms are similar to other gastrointestinal diseases, and because many physicians are unfamiliar with parasitic diseases. Stool specimens should be collected and examined over a period of at least three days. It is sometimes necessary to collect samples for four to five weeks. A positive diagnosis of giardiasis can be made by microscopic identification of the parasite in stool specimens. New tests that detect antigens (proteins) to Giardia in feces are especially useful for screening children in day-care settings, and for testing adults after treatment. Because of the high accuracy of the antigen tests, it is now rarely necessary to have an intestinal biopsy of the jejunum (part of the small intestine).
Please contact a physician, this one does not sound fun.
Prevention When dealing with sanitary sewers, cover your mouth (at the very least). Keep your hands away from your face, and don't drink the water.
