Where Pneumonia Is Found?

Pneumonia is a form of acute respiratory infection that affects the lungs. The lungs are made up of small sacs called alveoli, which fill with air when a healthy person breathes. When an individual has pneumonia, the alveoli are filled with pus and fluid, which makes breathing painful and limits oxygen intake.

What is the main cause of pneumonia?

Common Causes of Pneumonia

Viruses, bacteria, and fungi can all cause pneumonia. In the United States, common causes of viral pneumonia are influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (the virus that causes COVID-19). A common cause of bacterial pneumonia is Streptococcus pneumoniae (pneumococcus).

What is the most common way to catch pneumonia?

Catching pneumonia

The germs that can cause pneumonia are usually breathed in. People often have small amounts of germs in their nose and throat that can be passed on through: coughs and sneezes – these launch tiny droplets of fluid containing germs into the air, which someone else can breathe in.
