Bronchiolitis
Bronchiolitis is a common illness of the asthma later in life, but it's unclear whether the illness causes or triggers asthma, or whether children who eventually develop asthma were simply more prone to developing bronchiolitis as infants. Studies are being done to clarify the relationship between bronchiolitis and the later development of asthma.
Bronchiolitis is usually caused by a viral infection, most commonly influenza (flu), and human metapneumovirus.
Signs and Symptoms
The first symptoms of bronchiolitis are usually the same as those of a dehydrated from working harder to breathe, vomiting, and taking in less during feedings.
Contagiousness
The infections that cause bronchiolitis are contagious. The germs can spread in tiny drops of fluid from an infected person's nose and mouth, which may become airborne via sneezes, coughs, or laughs, and also can end up on things the person has touched, such as used tissues or toys.
Infants in child-care centers have a higher risk of contracting an infection that may lead to bronchiolitis because they're in close contact with lots of other young children.
