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.
