Which condition presents with coughing up blood and systemic symptoms such as fever and fatigue?

• A. Tuberculosis
• B. RSV
• C. COPD
• D. CHF

Answer: (A)

Coughing up blood with fever and fatigue points to an infectious lung process with systemic involvement. Tuberculosis fits this pattern well because Mycobacterium tuberculosis forms granulomas in the lungs and often develops cavitary disease, especially in the upper lobes. The fragile blood vessels near these cavities can erode and bleed, producing hemoptysis. At the same time, the body’s immune response and ongoing infection drive systemic symptoms like fever, fatigue, night sweats, and weight loss.

Other conditions can cause cough and even fever, but they don’t usually present with this combination. RSV is a viral infection that mainly causes acute bronchiolitis or pneumonia, particularly in children, and significant hemoptysis is not typical. COPD features chronic cough and sputum production with dyspnea, but fever and systemic fatigue are not defining. CHF can lead to pulmonary edema and, rarely, blood-tinged sputum, but fever is not a hallmark and the overall picture includes signs of heart failure rather than systemic infectious symptoms.
