Cough is a well-known symptom with many causes. The most common cause of a cough is a respiratory infection such as common cold, flu, croup, etc. Another common culprit is allergies, hay fever, asthma, etc. There are various other less common causes of acute cough and some can be very serious (e.g. pneumonia, abscess, etc.). Chronic cough may indicate a chronic infection (e.g. mycoplasma) or a chronic respiratory disease (Asthma; COPD; Emphysema, Chronic Bronchitis, etc.). Because there are so many possible causes of a cough, misdiagnosis of the less common causes can arise.
