Bronchitis in children can occur year-round but tends to increase significantly during seasonal transitions. The disease may progress to a severe condition if not detected and treated promptly. Parents are therefore advised to equip themselves with adequate knowledge about bronchitis in order to take preventive measures and ensure proper management, thereby safeguarding their child’s health.

What is bronchitis in children?

Bronchitis in children is an acute infection of the lower airways, including the trachea and major bronchi. The inflammation occurs in the bronchial mucosa, leading to swelling and excessive mucus production, which obstruct airflow.

Bronchitis is most common in children between 6 months and 3 years of age. During this stage, the respiratory system is still immature and highly susceptible to infectious agents.

Causes of bronchitis in children

Bronchitis occurs when bacteria or viruses invade the respiratory tract, initially affecting the nose, sinuses, and throat before spreading to the bronchial mucosa, causing inflammation and infection. Common viral and bacterial pathogens include:

• Viruses: Respiratory syncytial virus (RSV), adenovirus, influenza virus, rhinovirus, parainfluenza virus, etc.
• Bacteria: Streptococcus pneumoniae, Haemophilus influenzae, Chlamydia pneumoniae, Mycoplasma species, etc.

The most common cause of bronchitis in children is viral infection, with respiratory syncytial virus (RSV) being the leading pathogen. RSV infections often occur in outbreaks during the winter season, particularly among children under 5 years of age.

In addition, bronchitis in children may also result from other pathogenic factors such as fungi, parasites, exposure to tobacco smoke, and polluted environments. Children are also more susceptible to the condition following a common cold or after other respiratory illnesses.

Symptoms of bronchitis in children 

The symptoms of bronchitis may vary depending on the child’s age and the severity of the disease. The following are some typical manifestations:

• Dry cough or productive cough, with sputum typically white or yellow in color. During the acute phase, the child’s coughing becomes progressively worse, characterized by persistent and severe episodes, particularly at night.
• Breathing difficulties: The child may breathe rapidly or with effort, accompanied by chest retractions and wheezing.
• Fever: Initially mild, later progressing to high fever (>39°C).
• Nasal congestion and runny nose: Clear discharge or thick yellow/green mucus.
• Fatigue and poor feeding: The child may appear drowsy, lethargic, with loss of appetite or refusal to breastfeed.
• Other symptoms: Chest tightness, muscle aches, vomiting, and general fatigue

How is bronchitis different from the common cold?

Both bronchitis and the common cold are respiratory conditions that share several similar symptoms, which often leads to confusion.

• The common cold primarily affects the upper respiratory tract (nose and throat) and typically lasts 7–10 days. Symptoms include runny nose, sneezing, sore throat, mild fever, headache, and little to no sputum, often clear in nature.
• Bronchitis, on the other hand, is an infection of the bronchial tubes - the airways within the lungs and generally lasts longer than a cold. It is characterized by more severe symptoms such as persistent cough, breathing difficulties, wheezing, high fever, and fatigue.

Diagnostic methods for bronchitis in children

To accurately determine the condition and establish an appropriate treatment plan, physicians will combine clinical examination with paraclinical investigations.

Clinical examination: Physicians will review the child’s medical history, overall health status, presenting symptoms, and the duration of symptom onset. A physical examination is then performed, focusing mainly on the chest to assess for signs of bronchitis. Lung auscultation with a stethoscope is conducted to evaluate breath sounds.

Paraclinical investigations:

• Chest X-ray: Helps rule out other conditions such as pneumonia or pleural effusion and assesses the extent of lung damage.
• Blood oxygen measurement: Evaluates blood oxygenation levels, particularly in children experiencing breathing difficulties.
• Blood tests: Assist in assessing inflammation, infection, and the function of vital organs.
• Sputum test: Analyzes sputum samples to identify the causative bacteria or viruses.
• Pulmonary function test: Evaluates lung capacity and respiratory function, commonly performed in cases suspected of asthma.
• Polymerase chain reaction (PCR) test: Rapidly identifies pathogens, enabling more effective treatment planning.

Early consultation at Hong Ngoc, seizing the ‘golden window’ for bronchitis treatment in children

When a child shows early signs of bronchitis, it is important to seek pediatric consultation promptly for accurate diagnosis and timely intervention, helping to shorten the course of treatment and recovery.
