What is the differences between the symptoms of tuberculosis and pneumonia ?

Symptom wise: Tb tends to be a more gradual onset infection with night sweats, cough and weight loss over a number of weeks. Bacterial or viral pneumonia presents more rapidly over a day or so with fever and cough. Usually the chest x-rays differ.

See below: Pneumonia has an acute onset of cough, fever and sometimes shortness of breath and chest pains. Rales are heard on auscultation of the lungs and an infiltrate is seen on chest x-ray. Tb is a more chronic illness characterized by cough, night sweats, weight loss, a positive PPD skin test or gamma interferon release test with apical infiltrates on cxr. Sputum smears and cultures are + for afb/tb.
