Bronchiolitis is inflammation of the small airways in the lungs. Acute bronchiolitis is due to a viral infection usually affecting children younger than two years of age.[5] Symptoms may include fever, cough, runny nose, wheezing, and breathing problems.[1] More severe cases may be associated with nasal flaring, grunting, or the skin between the ribs pulling in with breathing.[1] If the child has not been able to feed properly, signs of dehydration may be present.[1]
Chronic bronchiolitis is the general term used for small airways disease in adults, notably in chronic obstructive pulmonary disease.[5][6]
Acute bronchiolitis is usually the result of infection by respiratory syncytial virus (72% of cases) or human rhinovirus (26% of cases).[2] Diagnosis is generally based on symptoms.[1] Tests such as a chest X-ray or viral testing are not routinely needed.[2]
There is no specific treatment.[3][7] Symptomatic treatment at home is generally sufficient.[1] Occasionally, hospital admission for oxygen, support with feeding, or intravenous fluids is required.[1] Tentative evidence supports nebulized hypertonic saline.[8][needs update] Evidence for antibiotics, antivirals, bronchodilators, or nebulized epinephrine is either unclear or not supportive.[9]
About 10% to 30% of children under the age of two years are affected by bronchiolitis at some point in time.[1][2] It commonly occurs in the winter in the Northern Hemisphere.[1] It is the leading cause of hospitalizations in those less than one year of age in the United States.[10][7] The risk of death among those who are admitted to hospital is about 1%.[4] Outbreaks of the condition were first described in the 1940s.[11]
