This presentation provides an overview of diarrhea, including its causes, symptoms, treatments, and prevention. Diarrhea is defined as loose, watery stools occurring 3 or more times per day. It is particularly dangerous for young children in developing countries, as it is the second leading cause of death for children under 5. The presentation covers acute diarrhea, which appears suddenly and lasts 5-10 days, versus chronic diarrhea, which is long-lasting. Common causes include bacteria, viruses, and parasites. Treatments discussed include oral rehydration, antibiotics, and home remedies. Prevention focuses on hand washing and drinking safe water.
