AB Croup  (acute  laryngotracheobronchitis)  is  a  respiratory  illness  of  childhood  and  one  of  the  most  common  causes  of  acute  stridor  in  children  seen  in  the  office  or  emergency  setting.  In  North  America,  croup  affects  approximately  3%  of  the  population;  it  is  most  common  in  children  aged  6  months–6  years,  with  the  largest  number  of  cases  occurring  in  children  1–2  years  of  age.1,2  The  male  :  female  ratio  for  croup  is  1.4  :  1.1  There  are  two  seasonal  peaks  of  croup  in  North  America:  the  first  in  autumn  and  the  second  in  late  winter.1  Because  of  biennial  increases  in  viral  epidemics,  the  number  of  croup  cases  is  50%  higher  in  odd-numbered  years  when  compared  with  even-numbered  years.3
