pulmonary infection

A pulmonary infection is an illness where germs like bacteria, viruses, or fungi invade the lungs, causing the tissue to become inflamed. This can lead to symptoms such as cough, chest pain, fever, shortness of breath, and fatigue. The infection can impair the lungs' ability to exchange oxygen and carbon dioxide effectively. Pulmonary infections vary from mild to severe and may require treatment like antibiotics or other medications. Good hygiene, vaccinations, and prompt medical care help prevent and manage these infections, which are especially serious for older adults, young children, and those with weakened immune systems.
