What is a Chronic Cough?

A cough lasting longer than 8 weeks is regarded as a prolonged or chronic cough. This is because a cough from an infection like a cold or flu will usually resolve after 2 weeks.

Coughing in children can be very distressing and can interfere with daily activities.

Causes of a chronic cough

There are many causes of a prolonged cough, depending on the nature, duration and age of the child. A dry cough at night with exercise could be due to asthma. A persistent wet cough could be due to more serious conditions such as cystic fibrosis. Other causes include post nasal drip, gastro-oesophageal reflux and autoimmune diseases.
