Winter and bronchiolitis
All you have to know about this disease so prevalent in the winter
Bronchiolitis is a respiratory disease caused by a viral infection that affects the smaller bronchi called bronchioles, which carry air to the lungs.
These airways become inflamed, clogged and filled with mucus, making the child has trouble breathing. Usually occurs in the first two years of life, with a higher incidence between 3 and 6 months.
The day care attendance and exposure to cigarette smoke may also increase the chances that an infant will develop bronchiolitis. Most of the time it is a mild disease, only a small percentage of children requiring hospitalization and mortality is low when there are no risk factors for developing serious illness.
The germs that cause bronchiolitis are usually viruses such as respiratory syncytial virus, adenovirus and influenza virus, among others.
What are the symptoms?
The first symptoms of bronchiolitis are usually the same as the common cold: runny nose and mild cough. These symptoms last a day or two and are followed by increased cough and the appearance of wheezes (high-pitched whistle when breathing out).
In some cases, gradually develops shortness of breath, rapid shallow breathing (60 to 80 times per minute), fast heartbeat, collapse the neck and chest with each breath, flaring of the nostrils, irritability, difficulty eating and or sleep.
Bronchiolitis usually lasts about 7 days, but sometimes a cough and mucus may continue for weeks. Generally, the disease reaches its peak in the second or third day after the child starts coughing and then gradually disappears.
