Introduction. Whooping cough (pertussis) is an acute bacterial illness produced by Bordetella pertussis affecting the respiratory system. Methods and Results. From 1995, three studies on the seroprevalence of pertussis in representative samples of the Catalan population have been carried out. The seroprevalence of pertussis in a representative sample of the Catalan population aged ≥5 years was studied in 1996, and the seroprevalence of pertussis in representative samples of pregnant women and neonates of Catalonia was studied in 2003 and 2013. The study carried out in 1996 found a prevalence of detectable levels (>4 EU/ml) of anti-PT antibodies of 75%. The studies in 2003 and 2013 in representative samples of pregnant women and neonates found an immunity protection levels against pertussis very low, with a prevalence of anti-PT <25 EU/ml of 75% in 2003 and a prevalence of anti-PT <40 IU/ml of 90% in 2013. Conclusions. The seroprevalence studies indicate that to improve protection levels in the population dTpa vaccines can be recommended in adolescents and adults.
