Bronchiolitis T2 Pediatric Practice: Infectious Disease YR 2009 FD 2009 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-148924-9 LK accesspediatrics.mhmedical.com/content.aspx?aid=6905803 RD 2022/05/27 AB Bronchiolitis, a common communicable respiratory illness manifesting with signs of small airways inflammation, primarily affects children younger than 2 years. Over one in five children will have bronchiolitis-associated wheezing in the first year of life.1 Bronchiolitis is the most common cause of hospitalization of children in the United States. Between 1% and 3% of all children are hospitalized as a result of bronchiolitis; one in four infants hospitalized for bronchiolitis are younger than 6 weeks of age, and over half are younger than 6 months of age. The mean length of hospital stay for children is 3 days (interquartile range 2–5 days), and the cost for care is estimated at over a half billion dollars annually.2–4 Despite the high prevalence of the disease and high rates of hospitalization, bronchiolitis is responsible for only about 100 pediatric deaths each year in the United States.5
