Overview

Pneumonia is an inflammation of the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing. Bacteria, viruses and fungi can cause pneumonia. The treatment involves administering antibiotics for bacterial infections or antiviral medications. Bronchodilators, oxygen therapy to maintain adequate oxygen levels and intravenous fluids to prevent dehydration may be given. Chest X-rays and blood tests, help assess the severity. The goal is to eradicate the infection and prevent respiratory failure.
