ABSTRACT

The word "pneumonia" takes its origin from the ancient Greek word "pneumon," which means "lung," so the word "pneumonia" becomes "lung disease." Medically it is an inflammation of one or both lungs' parenchyma that is more often, but not always, caused by infections. The many causes of pneumonia include bacteria, viruses, fungi, and parasites. This article will focus on bacterial pneumonia, as it is the major cause of morbidity and mortality. According to the new classification of pneumonia, there are four categories: community-acquired (CAP), hospital-acquired (HAP), healthcare-associated (HCAP) and ventilator-associated pneumonia (VAP).

Types of Bacterial Pneumonia

Some articles include both HAP and VAP under the category of HCAP, so defining HCAP is problematic and controversial.
