Pneumonia itself is not contagious; rather, it is often caused by infections that can spread, such as viruses or bacteria. For example, viral pneumonia can spread through respiratory droplets when an infected person coughs or sneezes. Bacterial pneumonia can also be transmitted in similar ways, but not everyone who is exposed will develop pneumonia. The speed of transmission can vary based on the pathogen and the individual's health.
