Prolonged cough in children: when to worry

In this article below, we hear from highly revered critical care consultant specialised in complex paediatric care, Dr Samira Neshat, provides us with an informative guide about prolonged cough in children.

When is a cough in children considered to be a prolonged, worrisome cough?

A prolonged cough in children can be a source of concern for parents and caregivers. A cough lasting more than four weeks is generally considered prolonged and warrants further investigation to determine the underlying cause and appropriate treatment.

What are the causes of a prolonged cough in children?

Several factors can lead to a prolonged cough in children. One common cause is an extended or recurrent viral infection, such as the common cold or flu. While these infections typically resolve within a couple of weeks, they can sometimes linger, especially in young children with developing immune systems.

Bacterial infections like pertussis (whooping cough) can also cause a persistent cough. In such cases, the cough is often severe and accompanied by a characteristic "whooping" sound during inhalation.

Another potential cause is asthma, a chronic respiratory condition that inflames and narrows the airways. Asthma-related coughs are usually dry and may worsen at night or with physical activity. Allergies to substances like pollen, dust mites, or pet dander can also trigger a prolonged cough. These coughs are often accompanied by other symptoms such as sneezing, itchy eyes, and a runny nose.

Gastroesophageal reflux disease (GERD) is another possible cause. In GERD, stomach acid flows back into the oesophagus, irritating it and potentially causing a chronic cough, particularly at night. Additionally, environmental irritants like cigarette smoke, pollution, and strong odours can exacerbate a cough or make it persist longer than usual.

What are severe symptoms to watch out for in a prolonged cough in children?

When dealing with a prolonged cough in a child, it is important to monitor for additional symptoms that may indicate a more serious condition. These symptoms include difficulty breathing, high fever, weight loss, or coughing up blood. If any of these signs are present, seeking medical attention promptly is crucial.

What are the treatment options?

Treatment for a prolonged cough depends on the underlying cause. For bacterial infections, antibiotics may be prescribed. Asthma and allergies might require inhalers, antihistamines, or other medications to manage symptoms. In cases of GERD, dietary modifications and medications to reduce stomach acid can help alleviate the cough.

How can a prolonged cough in children be best avoided?

Preventative measures include ensuring the child avoids known allergens, maintaining good hand hygiene to prevent infections, and avoiding exposure to smoke and other environmental irritants. Keeping the child's vaccinations up-to-date, including the whooping cough vaccine, is also essential.
