Giardia

Giardia is a tiny, single-celled parasite that causes an infection called giardiasis, affecting the intestines. It spreads through contaminated water, food, or contact with infected people or animals. The parasite attaches to the lining of the small intestine, disrupting normal absorption of nutrients and leading to symptoms like diarrhea, bloating, stomach cramps, and nausea. Giardiasis can be treated effectively with medication, and prevention involves good hygiene, drinking clean water, and proper sanitation. Since it’s common worldwide, awareness and preventative measures are key to reducing infection risk.
