Pneumonia can be passed from an infected person to a non-infected person through droplet infection. This comes about when a person who is infected with the virus or bacterium that causes pneumonia happens to cough, thus helping these pathogens to spread in the surrounding air.

  • This means that any person who happens to inhale the pathogens is likely to develop pneumonia within the next few days.

However, the risk of developing pneumonia depends on the strength of the immune system as well as the type of pathogens involved. Some of these pathogens are highly contagious, meaning that people with a compromised immune systems are highly likely to catch the disease.

To sum up: Pneumonia is contagious, but if you have a healthy immune system, it may not effect you.
