What is Bronchiolitis?

Bronchiolitis is a common respiratory infection in infants and young children that causes inflammation and congestion in the smallest airways of the lungs, known as bronchioles, most often caused by respiratory syncytial virus. It typically begins with mild cold-like symptoms that progress over a few days to more pronounced breathing difficulty, wheezing, and rapid breathing as the swollen airways make it harder for air to move in and out of the lungs. While most cases are mild and resolve with supportive home care, infants under six months and those with underlying health conditions are at higher risk of more severe illness requiring hospitalization.

What are the main symptoms of Bronchiolitis?

The most common symptoms include: Runny or congested nose; mild fever; cough that may worsen over several days; wheezing. Early recognition is key to prompt diagnosis and effective treatment.

Is Bronchiolitis contagious?

Yes, Bronchiolitis is contagious. It can spread from person to person. Practice good hygiene, avoid close contact with infected individuals, and follow isolation guidelines if advised by a doctor.

How is Bronchiolitis treated?

Treatment options include: Most cases are managed with supportive care at home; including keeping the child hydrated; using saline nasal drops and gentle suction to relieve nasal congestion. Treatment should always be guided by a qualified Pediatrics specialist. Do not self-medicate.

Can Bronchiolitis be prevented?

While Bronchiolitis cannot always be fully prevented, several measures can reduce risk: Frequent handwashing and avoiding close contact with sick individuals; avoiding exposure to tobacco smoke; breastfeeding to support immune protection in infants.

When should I see a doctor for Bronchiolitis?

Consult a Pediatrics specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
