Incidence of pertussis in the province of Pesaro-Urbino (Italy)

Pertussis vaccination coverage in the Marche region is one of the lowest in Italy, with the province of Pesaro-Urbino remaining stable below 95% coverage since at least 2013. In this paper, we retrospectively analyzed all whooping cough notification cards arriving at the prevention department of the Area Vasta 1 Health Office in the Marche region and relating to the Pesaro-Urbino province (Italy). Between 2012 and 2017, there were 28 reported cases of pertussis with a peak in 2016 (11 cases, of which seven were in Urbino). The 28 patients were mostly male (65%), and had a mean age of 9 years. Three of these were not Italian. Between 2012 and 2017, the district of Pesaro reported the highest number of cases (almost 46.5% of the total), followed by Urbino (28.5%) and Fano (25%). The average incidence in the province in the period in question, still under 2 cases/100,000 inhabitants, arrived in 2016 at 4 cases/100,000 inhabitants. In particular, in Urbino there was an unforeseen incidence >8 cases/100,000 inhabitants. There were no deaths, although two children (both under 12 months of age) were hospitalized. Our data confirm that in 2016 there was a pertussis epidemic in Urbino (Italy).
