We compared the characteristics and discharge destination of patients with a microbiological diagnosis of pertussis (species-specific polymerase chain reaction [PCR] and/or culture in Bordet agar until 2015 and species-specific PCR thereafter) before and after the introduction of routine vaccination of pregnant women. The indications to request microbiological testing for confirmation were clinical (clinical suspicion in patients aged 0–14 years by the physician in charge, independently of patient age and the clinical presentation), and there were no changes in the criteria for ordering these tests during the study period. We defined the January 2008 to July 2015 interval as the prevaccination period, the last six months of 2015 as the window period and the 3-year interval from 2016 to 2018 the postvaccination period. We defined the impact on the resurgence of pertussis as the change in the episodes of pertussis with microbiological confirmation (and specifically in episodes in infants aged less than 6 months) and the change in the associated hospital admission rate.</p><p id="par0020" class="elsevierStylePara elsevierViewall">During the period under study, there were 616 204 emergency visits, out of which 202 corresponded to cases of pertussis with microbiological confirmation (0.03%; 95% confidence interval [CI], 0.03−0.04), none diagnosed exclusively based on a positive culture in Bordet agar: 147 (73.1%) in the prevaccination period, 15 (7.5%) in the window period and 40 (19.8%) in the postvaccination period. There were more cases of pertussis diagnosed in the prevaccination period: 1.1 cases per 10 000 recorded visits to the PED in 2008 compared to 8.5 per 10 000 visits in 2015. This rate decreased to 2.1 cases per 10 000 visits in the postvaccination period. Of the 202 patients with a microbiological diagnosis of pertussis, 86 were infants aged less than 6 months (42.8%): 74 in the prevaccination period (50.3% of the cases of pertussis diagnosed during this period), 3 cases (20%) in the window period and 9 in the postvaccination period (22.5% of the total cases diagnosed in the postvaccination period, a significant decrease compared to the prevaccination period; <span class="elsevierStyleItalic">P</span> < .01). The mothers of 6 of the 9 previously healthy patients aged less than 6 months given a diagnosis of pertussis in the postvaccination period (66.7%) had been vaccinated during pregnancy. In addition, there was a change in the number of orders of microbiological tests for confirmation of pertussis: there was a substantial increase through the prevaccination period followed by a decrease after introduction of routine vaccination of pregnant women, although it did not reach the initial level of the prevaccination period (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). One possible explanation is that severe cases in infants, while having decreased significantly in frequency, have not been eradicated and physicians maintained a higher level of suspicion in the postvaccination period. Overall, 62 patients were admitted to hospital, 58 in the prevaccination period (39.5% of cases of pertussis diagnosed in the same period) and 4 in the postvaccination period (10% of cases of pertussis diagnosed in the same period; <span class="elsevierStyleItalic">P</span> < .01).</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><p id="par0025" class="elsevierStylePara elsevierViewall">The sole difference in the clinical presentation of pertussis between the pre- and the postvaccination periods was the increase in the age of patients with a diagnosis of pertussis in the postvaccination period (median age, 29 months vs 5 months in the prevaccination period; <span class="elsevierStyleItalic">P</span> < .05) (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>).
