A comprehensive primary care case study for 2025/2026 on a 25-year-old male presenting with four days of progressively worsening febrile diarrhea, mucoid stools, localized left lower quadrant pain, orthostatic hypotension, and recent travel to rural India.

Covers red flag assessment, travel history significance, differentiation between bacterial enteritis (Campylobacter, Shigella, Salmonella, Typhoid), amebiasis, and inflammatory bowel disease. Includes interpretation of CBC, CMP, inflammatory markers, stool studies, blood cultures, empiric azithromycin therapy, contraindication of antimotility agents, and comprehensive patient education on isolation, rehydration, and public health reporting. Ideal for advanced practice nurses, medical students, and primary care clinicians managing travel-associated gastrointestinal infections.
