It is an inflammation of the air sacs or alveoli in the lungs. Pneumonia is not a single diseases but rather several types of diseases each one occurs due to a different contaminant (bacteria, virus, or fungus). The contaminants reach the lungs through inhalation, blood, or infection near the lungs. When infected, the alveoli may be filled up with fluid.
There are two types of Pneumonia: pneumonia acquired in health institutions (hospital or nursing care institutions), and also community-acquired pneumonia.
The first type is often more severe because the patients already has a another disease, the reason why he got to the hospital in the first place.
