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 can cause coughing, fever, and trouble breathing. According to the World Health Organization (WHO), pneumonia affects people of all ages, but it can be more serious for young children, older adults, and those with weak immune systems.

It is important to know the signs of pneumonia early. While symptoms can vary, many people notice changes in how they feel. For example, you might feel tired or have a cough that will not go away. Below are common pneumonia symptoms:

The Centers for Disease Control and Prevention (CDC) notes that certain people are at higher risk. For instance, young children and seniors are more likely to get pneumonia.
