title: [Incidence of whooping cough in the city of Barcelona between 1999 and 2011].
abstract: BACKGROUND
  The aim of the study was to describe the long-term incidence of whooping cough in a large city.
  
  
  METHODS
  Descriptive study of the cases reported in the notifiable disease registry between 1999 and 2011 in Barcelona.
  
  
  RESULTS
  An increase in incidence was observed, especially in children and in the year 2011. Children younger than one year still were most affected, with a specific rate of 426.87/100,000 in 2011.
  
  
  CONCLUSIONS
  A new approach in adolescent and adult vaccination is needed to provide more protection to younger children, as well as research to assess a possible shift in the bacteria itself.
