You can also get these types of pneumonia by coming into contact with surfaces or objects that are contaminated with pneumonia-causing bacteria or viruses. This means they can spread from person to person through inhalation of airborne droplets from a sneeze or cough. These sacs, called alveoli, fill with fluid or pus, making it difficult to breathe.īoth viral and bacterial pneumonia is contagious. It leads to inflammation in the air sacs of one or both lungs. Pneumonia is an infection caused by bacteria, viruses, or fungi.
