Both bronchitis and pneumonia affect the lungs, but they’re not the same. 🔹 Bronchitis is the inflammation of the bronchial tubes, often caused by a viral infection. It usually leads to a persistent cough, sometimes with mucus, chest discomfort, and mild fatigue. 🔹 Pneumonia is more serious, it affects the air sacs in the lungs, which can fill with fluid. Symptoms often include cough with phlegm, high fever, chills, and shortness of breath. If your cough lingers or you experience high fever and difficulty breathing, don’t ignore it, see a healthcare professional to get the right diagnosis and treatment.
