Bronchitis vs. Pneumonia: Key Differences in Symptoms and Severity
Bronchitis is inflammation of the bronchial tubes (airways) usually following a viral infection. Pneumonia is infection of the lung tissue itself (alveoli) and can be caused by bacteria, viruses, or fungi. Pneumonia is generally more serious and may require hospitalization.

Professional Diagnosis
Bronchitis is diagnosed clinically. Pneumonia typically requires a chest X-ray showing lung infiltrates, along with blood tests and possibly sputum cultures.
Treatment for Bronchitis
Usually resolves without antibiotics in 1-3 weeks. Treatment focuses on symptom relief: cough suppressants, fluids, and rest. Antibiotics only if bacterial infection is confirmed.
Treatment for Pneumonia
Bacterial pneumonia requires antibiotics. May need hospitalization for IV antibiotics, oxygen therapy, and supportive care. Vaccination (pneumococcal, flu) is key for prevention.
When to See a Doctor
Seek care if cough persists beyond 3 weeks, produces bloody mucus, or is accompanied by high fever, rapid breathing, or chest pain. Elderly, immunocompromised, and very young patients should seek early evaluation.
