Walking Pneumonia Versus Regular Pneumonia

Walking pneumonia is simply a milder case of pneumonia. In this case, a person does not appear as sick as someone with regular pneumonia -- they are still able to "walk around." They may feel sick; however, their symptoms are not as severe.
Walking pneumonia can be caused by a number of different types of bacteria and viruses. The most common type is caused by the bacterium Mycoplasma pneumoniae (see Mycoplasma Pneumonia).
Walking pneumonia is common, accounting for about 20 percent of pneumonia cases in middle and high school students and up to 50 percent of cases in college students and military recruits.

How Contagious Is Pneumonia?

The germs that cause pneumonia are contagious. When spread, they typically cause upper respiratory symptoms such as a cough, runny nose, or sore throat.
The germs that cause pneumonia are usually found in the mouth and nose of the infected person. They can be spread easily to another person either through the air or by touching a contaminated surface. Most often, they enter the person's body through the mouth, nose, or eyes.
