BACKGROUND: Pneumonia is an infection in the lungs caused by breathing in bacteria or because of illness. It becomes much easier for infection to cause pneumonia after having a cold or flu. These illnesses can make it more difficult for the lung to fight off infections caused by bacteria. Pneumonia can range in seriousness from mild to life-threatening.
TYPES OF PNEUMONIA: There are three main types of pneumonia: community-associated pneumonia, healthcare-associated pneumonia, and "walking" pneumonia. Community-associated pneumonia occurs when one gets the infection from a place in everyday life; such as school, work, or one's home. Healthcare-associated pneumonia comes when the infection originates from a hospital or nursing home. What doctors sometimes call "walking" pneumonia is simply a term for more mild pneumonia symptoms.

SYMPTOMS: There are a variety of symptoms associated with the bacteria which can cause pneumonia. The most common are:
HEALTHCARE-ASSOCIATED PNEUMONIA: Perhaps the most serious type of pneumonia is healthcare-associated pneumonia. The infection is more harmful because, many times, the bacteria which cause the infection can be multidrug-resistant. Even with drug-resistant strains of the illness, the best way to treat the infection is with a course of antibiotics. However, even these may cause the infection to become more resistant.
