Which condition is defined as inflammation of the lungs, with viral and bacterial types?

• A. Pneumonia
• B. TB
• C. COVID-19
• D. Pulmonary edema

Answer: (A)

Inflammation of the lung tissue caused by infection fits this description. Pneumonia describes inflammation of the alveoli and surrounding lung areas that can be due to bacteria, viruses, or both, leading to filled air spaces (consolidation) and impaired gas exchange. Clinically, people often have cough, fever, shortness of breath, and chest discomfort, with exam findings like crackles and possible pleural involvement; imaging typically shows focal or lobar consolidation. TB is a chronic granulomatous infection of the lungs, with a different pattern and course than acute infectious pneumonia. COVID-19 is a viral pneumonia caused by SARS-CoV-2, but the broad category of pneumonia includes bacterial, viral, or mixed etiologies. Pulmonary edema involves fluid accumulation in the lungs from heart or vascular problems, not an inflammatory infection of the airspaces.
