Frequency
Bacterial tracheitis may occur in any pediatric age group. Gallagher et al reported 161 cases of patients younger than 16 years. [9] The age range was from 3 weeks to 16 years, with a mean age of 4 years. This is in contrast to viral laryngotracheobronchitis, which occurs in patients aged 6 months to 3 years.
The predominant morbidity and mortality is related to the potential for acute upper airway obstruction and induced hypoxic insults. The mortality rate has been estimated at 4-20%. In the acute phase, patients generally do well if the airway is adequately managed and if antibiotic therapy is promptly initiated.
Sex
In most epidemiologic studies, male cases are preponderant. Gallagher et al reported a male-tofemale predominance of 2:1.
United States: A study that described the frequency and severity of complications in hospitalized children younger than 18 years with seasonal influenza (during 2003-2009) and 2009 pandemic influenza A(H1N1) (during 2009-2010) reported that out of 7293 children hospitalized with influenza, less than 2% had complications from tracheitis. However, along with other rare complications, tracheitis was associated with a median hospitalization duration of more than 6 days, with 48%-70% of children requiring intensive care.
