Causes, symptoms, and treatment of lung infection

How do you treat a lung infection?

During respiration, the lungs release oxygen into the bloodstream, and the body’s cells need oxygen for their activities, and this oxygen is heavily inhaled by lung disease. Lung diseases include asthma, chronic obstructive pulmonary disease, influenza, pneumonia, tuberculosis, lung cancer, and more.

Lung infections can be caused by viruses, bacteria, and sometimes even fungi, and one of the most common types of lung infections is pneumonia. Pneumonia, which affects the air sacs of the smaller lungs, is mostly caused by infectious bacteria but can also be caused by a virus.

Causes, symptoms, and treatment of lung infection

How does a lung infection heal:

Viruses can also attack the lungs or airways that go to the lungs, and this is called bronchiolitis, and viral bronchiolitis is more common in babies.

Pulmonary infections such as pneumonia are usually mild but can be serious, especially for people with weakened immune systems or chronic conditions such as chronic obstructive pulmonary disease.

Symptoms of a lung infection:

Symptoms of a lung infection can range from mild to severe, depending on several factors, including your age and general health, and can be caused by a virus, bacteria, or fungus. Symptoms may look like a cold or the flu, but they persist.

Cough that causes thick mucus

Coughing helps your body get rid of mucus caused by inflammation of the airways and lungs. This mucus may also contain blood.

In bronchitis or pneumonia, you may cough up thick mucus that may be a certain color, including:

  • Transparent
  • White
  • Green
  • White gray

Even after other symptoms improve, the cough can live for several weeks.

Chest pain from a lung infection is often described as sharp or suffocating. Chest pain worsens when you cough or take deep breaths, and sometimes you can feel severe pain in the middle of your back.


Fever occurs when the body tries to fight infection. Normal body temperature is usually around 37 degrees Celsius, and if you have a bacterial lung infection, your fever may reach 40.5 degrees Celsius.

 Fever above 38.9 ° C often leads to many other symptoms, including:

  • Bacteria such as Streptococcus pneumonia (most common), Haemophilus influenza, and Mycoplasma.

Viruses such as influenza virus or RSV

Rarely, lung infections can be caused by fungi such as Pneumocystis gyrus, Aspergillus, and histoplasmosis capsules.

Lung fungal infections are more common in people with immune system problems and certain types of cancer or HIV or the use of immunosuppressive drugs.
