Pneumonia does not “turn into” tuberculosis because TB is caused by a different organism (Mycobacterium tuberculosis). However, two clinical realities matter. First, early TB can sometimes resemble pneumonia, leading to initial misclassification. Second, after an acute infection, delays in recognizing an underlying condition can occur if symptoms persist. If cough lasts beyond 2–3 weeks, or there are night sweats, weight loss, blood in sputum, or lack of improvement despite treatment, TB and other diagnoses should be considered. In such situations, clinician evaluation and TB-specific testing are essential to ensure the correct diagnosis and therapy.
