Cough is a protective reflex to remove irritants, microbes, or foreign particles from the airways. A cough without production of phlegm (mucus) is called dry cough.

Coughing several times a day can occur in viral illnesses, such as common cold, and it usually resolves within a few weeks. If you notice persistent cough, lasting more than two to three weeks, in your child, visit a pediatrician (1).

Read this post to know more about the causes, symptoms, diagnosis, treatment, home remedies, and prevention for dry cough in children.

Causes Of Dry Cough In Children

There can be various reasons for dry cough. Common causes in children may include the following (1).

  1. Viral respiratory infections such as common cold, croup, viral pneumonia, or acute bronchitis
  1. Post-viral cough (post-infectious cough or lingering cough) is seen at the end of viral respiratory tract infections. This is due to airway hyperresponsiveness.
  1. Whooping cough or pertussis caused by bacteria Bordetella pertussis leads to multiple coughs. A whooping sound on inhalation after a coughing fit is heard in this disease, and emergency care is required.
  1. Allergies and asthma can cause dry cough in some children. Wheezing can be another prominent symptom along with asthmatic cough.
  1. Irritants such as smoke, perfumes, dust, or smell of certain chemicals can trigger short spells of dry cough in some children.
  1. Inhaled foreign bodies, such as nuts or parts of toys, could cause cough in children. The child could continue to have a cough until the foreign object is removed from the airways.
  1. Dry weather may cause dry cough due to airway irritation and throat dryness.
  1. Sinus infection (sinusitis) may cause dry cough due to postnasal drip.
  1. Gastroesophageal reflux or acid reflux from the stomach may stimulate cough reflex, resulting in dry cough.
  1. Habit cough (psychogenic cough or somatic cough syndrome) is a cough without any medical reasons. This can be a loud barking or honking cough, sometimes seen after a child has recovered from airway infections.

Diagnosing dry cough can be challenging since it can occur in several viral and bacterial infections in children. It is also possible to have a dry cough due to non-infectious reasons. Seek expert help to identify the exact cause of dry cough in children.
