2. **Identifying Conditions Requiring Rehydration**:
- **Diarrhea**: This condition involves frequent watery bowel movements, which can lead to significant fluid loss and dehydration.
- **Cholera**: This is an infectious disease that causes severe watery diarrhea and vomiting, leading to rapid dehydration and electrolyte imbalance.
