Bronchiolitis is a common infection affecting the lower respiratory tract that predominantly affects babies and infants younger than two years old. Fortunately, it is rarely serious. Children with bronchiolitis usually experience mild symptoms and fully recover within a few weeks without any medical intervention. However, in some cases, the symptoms of bronchiolitis can be more severe, and hospital admission may be required.
At first, the symptoms of bronchiolitis mimic those of a common cold, with the child developing a runny nose and cough. Other symptoms develop gradually, including a low-grade fever that rarely rises too high. A persistent dry cough is also common. Affected children may also have trouble eating or taking food and may sound wheezy when they breathe.
