What is pneumonia?

ANSWER

Pneumonia is a lung infection that can be mild or so severe that you have to go to the hospital.

It happens if an infection causes the air sacs of the lungs (doctors call these “alveoli”) to fill up with fluid or pus. That can make it hard for you to breathe in enough oxygen to reach your bloodstream.

Anyone can get this lung infection, but infants younger than age 2 and people over age 65 have the highest odds. That’s because their immune systems might not be strong enough to fight it.
