Are you worried about your child’s frequent bouts of cough and cold that last for a long time? It could be bronchitis. Read on to find out more about the infection.

Eight-year-old Rahul has been suffering recurrent bouts of cough and cold. His mother, Seema, is worried as the little boy keeps complaining of tightness in the chest and a sore throat. A visit to the doctor confirms Seema's worst fears — her son has bronchitis. And, this is not the first time that Rahul has been diagnosed with the ailment. During his growing up years, he suffered from bronchitis almost two to three times in a year.
Bronchitis is an infection in the large airway passages, which connect the windpipe to the lungs. In this condition, there is an inflammation of the mucous membrane lining the medium and the large breathing tubes (bronchus). It starts with a common cold, sinusitis or flu and develops into bronchitis.
The symptoms include fever and dry cough during early illness, and sputum, when a bacterial infection sets in. The child can also have chest pain, breathlessness, chest tightness associated with wheezing, lethargy, poor intake and irritability as the illness progresses. These symptoms occur more often in the night. Bronchitis can start as an acute illness or sometimes become chronic, lasting more than a few weeks or months, depending on the child’s immunity and response to treatment.
The most common cause of bronchitis in children is a viral respiratory infection, but can also be caused by a bacterial infection with prolonged illness. Sometimes, children who are less than two years, can suffer from acute airway injury called bronchiolitis. The symptoms of bronchitis or bronchiolitis can mimic a common cold or flu; hence, there can be a delay in the diagnosis.
Many of these symptoms overlap with early childhood asthma but are mistakenly treated as bronchitis or bronchiolitis with repeated courses of antibiotics. Parents should be aware of these symptoms and consult a child specialist to get a correct diagnosis and initiate proper treatment.
As the present generation of children get vaccinated early in life, their immunity is much less developed than in children, who suffer from natural infections in early childhood. This could be one of the reasons for why children suffer from prolonged bouts of bronchitis following a viral or bacterial respiratory infection.
Childhood bronchitis is usually self-limiting, lasting 5–7 days, but may occasionally last for anything between 10 days and four weeks, if there is a prolonged illness or a bacterial infection. The delay in recovery may be due to undetected reactive airway disease (a condition where the airway is obstructed because of external factors), an allergy, a foreign body trapped in the airways, or other medical conditions such as cystic fibrosis, bronchiectasis and ciliary dyskinesia.
The non-infectious causes of bronchitis include repeated exposure to irritants like dust, smoke, indoor and outdoor pollution, tobacco smoke and allergens.
So, why does Rahul get bronchitis almost twice every year? Apart from a respiratory infection, the child could be suffering from repeated episodes of bronchitis (allergic bronchitis) due to newer strains of viruses each year. The treating physician should recognise the condition and treat with appropriate medications, so that the suffering is not prolonged.
Look out for worrying signals when your child falls ill. Discuss with your child’s paediatrician about the measures to be taken to control the recurrent episodes. This will save your child from prolonged illness.
