Bronchitis and pneumonia are two different types of diseases. Bronchitis often presents only with symptoms like coughing and expectoration, while fever and wheezing are relatively less common. Pneumonia is a common infectious disease of the respiratory system, and its main clinical symptoms include fever, cough, expectoration, wheezing, chest pain, etc. We can differentiate bronchitis from pneumonia through pulmonary imaging, as bronchitis on imaging is characterized by coarse patterning and disorganized structures in both lungs.
