What is Pneumonia?
Pneumonia is a lung infection that can make it hard to breathe. It happens when germs, such as bacteria, viruses, or fungi, enter the lungs. Because of this, the air sacs in the lungs fill with fluid or pus. As a result, people with pneumonia often feel very sick. Pneumonia can affect anyone, but it is more serious in young children, older adults, and people with weak immune systems. According to the CDC, pneumonia is a leading cause of hospital visits worldwide. Early treatment helps prevent serious problems.
