Lung Insfection

Pneumonia is an infection of the lungs that may be caused by bacteria, viruses, or fungi. The infection causes the lungs’ air sacs (alveoli) to become inflamed and fill up with fluid or pus. That can make it hard for the oxygen you breathe in to get into your bloodstream. The symptoms of pneumonia can range from mild to severe, and include cough, fever, chills, and trouble breathing. Many factors affect how serious a case of pneumonia is, such as the type of germ causing the lung infection, the person’s age, and their overall health. The people most at risk are infants and young children, adults 65 or older, and people who have other health problems.
