65-year-old homeless man with cough, abdominal pain and fever; coughing up bright red sputum. What condition should you suspect?

Suspect tuberculosis when a patient with risk factors has a prolonged cough and fever and may cough up blood. In a homeless person, crowded living conditions increase exposure to Mycobacterium tuberculosis, making TB a top consideration with this symptom pattern. TB commonly presents with a chronic cough lasting weeks, low-grade fever, and sometimes hemoptysis as the infection erodes airways. By contrast, pneumonia usually comes on acutely with high fever and rapidly worsening lung findings, bronchitis is typically a shorter illness without persistent systemic signs or significant bleeding, and lung cancer tends to present with a longer history of risk factors like smoking and symptoms such as weight loss, not the acute infectious picture described here.
