Infection occurs when the host (cat, human, or other mammals) ingests Giardia cysts with: – Contaminated water – (Less commonly) Contaminated food – Via direct fecal-oral contact (unwashed hands).
The inflammation in the intestine and the improper digestion lead to diarrhea, which has a particularly foul smell because the food has not been fully processed in the digestive tract.
