What Is Cough?

Coughing isn't a condition in itself, but an indication of an underlying medical condition. Coughing caused by bacterial or viral upper respiratory infections are contagious, but coughing caused by disorders like asthma and COPD is not.

Coughing isn't a condition in itself, but an indication of an underlying medical condition. Coughing caused by bacterial or viral upper respiratory infections are contagious, but coughing caused by disorders like asthma and COPD is not.

Cough is not a disease in itself, but a symptom of an underlying medical condition. A cough can be voluntary or involuntary, and it is the body's way to help clear the airways of irritants and to prevent infection.

  • Sore throat
  • Runny or stuffy nose
  • Hoarseness

Is a Cough Contagious?

Cough itself is not contagious as it is a symptom of another condition, however, some causes of cough can be contagious.

Infectious causes of cough such as viruses, bacteria, and fungi can be transmitted from person-to-person through respiratory droplets propelled into the air when an infected person sneezes or coughs.

How Is Cough Diagnosed?

Cough is diagnosed with a history and physical exam. Tests may be used to help diagnose the cause of the cough.

  • Lung imaging
    • Chest X-ray
    • Computerized tomography (CT) scan of the chest
  • Lung function tests
  • Swab of inside the nose to test for COVID-19
  • Lab tests of phlegm that is coughed up
  • Acid reflux testing
    • Upper endoscopy
    • pH probe
  • Allergy tests

    • Antibiotics do not treat cough caused by viruses such as the common cold, flu, or COVID-19
  • Inhaled bronchodilators and inhaled steroids to treat asthma and COPD
