Is pneumonia contagious?

Pneumonia can be contagious. Some of the viruses and bacteria that cause pneumonia are more contagious than others. People with a weak immune system are more likely to catch pneumonia from someone who already has it. But in most cases, if the germs that cause pneumonia are passed on to someone, they create a milder infection, such as the common cold.
