What Is Bronchiolitis
Dura Johnson
Bronchiolitis is a common respiratory illness that primarily affects infants and young children. It is typically caused by a viral infection, most commonly the respiratory syncytial virus (RSV). Other viruses, such as adenovirus, influenza, and parainfluenza, can also cause bronchiolitis.
The condition primarily affects the bronchioles, which are small airways in the lungs. Bronchiolitis often starts with symptoms similar to those of a common cold, such as a runny nose, cough, and mild fever. As the illness progresses, it can lead to more severe respiratory symptoms, including wheezing, difficulty breathing, and increased respiratory rate.
Bronchiolitis is more common during the winter months, and it is highly contagious. It spreads through respiratory droplets when an infected person coughs or sneezes. The virus can also live on surfaces for several hours, contributing to its transmission.
In most cases, bronchiolitis is a self-limiting illness, meaning it tends to resolve on its own. Treatment focuses on relieving symptoms and providing supportive care, such as ensuring proper hydration and monitoring breathing difficulties. Severe cases may require hospitalization, especially in infants with breathing difficulties.
It's essential for parents and caregivers to seek medical attention if a child shows signs of respiratory distress or if symptoms worsen. Preventive measures, such as frequent handwashing and avoiding close contact with sick individuals, can help reduce the risk of bronchiolitis. Additionally, vaccination against RSV is recommended for certain high-risk infants.
