What is Viral Pneumonia?

Pneumonia is a bacterial, viral, or fungal infection of either one or both sides of the lungs that causes the air sacs within the lungs of the lungs to fill up with fluid or pus. Viruses, bacteria, a fungus, or (in rare cases) parasites are the main cause of such disease.

Causes of Pneumonia

Bacteria, viruses, and fungi infections can cause pneumonia. These infections cause inflammation in the air sacs, or alveoli, of the lungs. This inflammation causes the air sacs to fill with fluid and pus.

BacteriaBacteria are the most common cause of pneumonia in adults. Many types of bacteria can cause bacterial pneumonia. Bacterial pneumonia can occur on its own or develop after you’ve had a viral cold or the flu. Bacterial pneumonia often affects just one lobe, or area, of a lung. When this happens, the condition is called lobar pneumonia.

Viruses – Viruses that infect the respiratory tract may cause pneumonia. The influenza or flu virus is the most common cause of viral pneumonia in adults. Respiratory syncytial virus (RSV) is the most common cause of viral pneumonia in children younger than one year old.

Fungi – It occurs in people who have weak immune systems due to HIV/AIDS or the long-term use of medicines that suppress their immune systems, such as those used to treat cancer or as part of an organ or blood and marrow stem cell transplant procedures.

An individual may not realize it’s more serious until it lasts longer than these other conditions. A doctor will diagnose pneumonia based on the patient’s medical history, a physical exam, and test results. The doctor may be able to diagnose with a certain type of pneumonia based on how you got your infection and the type of germ causing your infection.
