A pulmonary infection is a general term given to a number of lung-related infections that occur when parasites, viruses or bacteria enter the lungs impairing the regular defense mechanisms of the organs.  Pneumonia, bronchitis and influenza are examples of pulmonary infections and account for a number of illness and deaths across the world.


There are many causes that can lead to a pulmonary infection such as the Flu or bronchitis.  Parasites and bacteria that enter the lung region can cause serious inflammation and infection to the lungs creating a myriad of symptoms.


Pulmonary infections present themselves in a variety of illnesses and conditions and range in terms of severity.  In most cases, if a person has been diagnosed with the Flu, bronchitis—or in a more extreme case, pneumonia—then a person will experience fever, chills, exhaustion, aches and muscle pains.  A persistent, dry cough, runny nose and stomach irritations such as nausea, vomiting and diarrhea may also persist.


Pulmonary infections can most often be treated with antivirals, antibiotics and over-the-counter treatments.  Advanced conditions will require hospitalization so that the symptoms associated with the illness can be monitored closely.
