Background. The objective of this paper is to describe the main results of pertussis surveillance in Catalonia and to assess its evolution in recent years. Material and Methods. According to case definition in Catalonia, suspicious and confirmed cases reported to the Notifiable Disease Reporting System in the period 2011-2018 have been included, after validation of reports made by health professionals has been completed. Results. In 2011, a reemergence of whooping cough was observed in Catalonia, which remained during the period of study (2011-2018), although since 2016 a decrease in incidence has been observed. The highest rate for the period was that of 2015, which reached the value of 49.2 per 100,000 inhabitants. Children under 1 year showed the highest incidence rates, but decreased over the period. The recommendation to vaccinate against pertussis pregnant women in the third trimester of pregnancy, which started in 2014, has impacted on the incidence in children under 1 year and especially in children under 2 months, decreasing significantly. The high percentage of cases in children aged 5-18 years with 4-5 doses of vaccine shows lower effectiveness for acellular vaccine versus the whole cell vaccine. Conclusions. Control of whooping cough is currently a challenge that services epidemiological surveillance and public health have to face.
