What is Pneumonia?
Pneumonia is a lung infection that can make it hard to breathe. It happens when germs, like bacteria or viruses, enter the lungs. As a result, the air sacs in the lungs fill with fluid or pus. This makes it tough for your body to get enough oxygen. Anyone can get pneumonia, but it is more serious for young children, older adults, and people with weak immune systems. According to the World Health Organization (WHO), pneumonia is a leading cause of illness worldwide.

Symptoms of pneumonia can vary from mild to severe. Sometimes, they start suddenly. Other times, they develop slowly. Early treatment can help prevent problems.
