We describe a pertussis outbreak in the Vallès region of Catalonia, from September 2023 to April 2024. Incidence was high in children aged 10-14 years compared with previous outbreaks. Limited impact in newborns could be explained by the high vaccination coverage during pregnancy and at 11 months of age in 2022, at 85% and 94.1 %, respectively. A third booster vaccine dose during preadolescence should be considered and vaccination coverage in pregnant women be improved to control future outbreaks.
我们描述了 2023 年 9 月至 2024 年 4 月在加泰罗尼亚的巴利阿里群岛地区发生的百日咳疫情。与以往的疫情相比,10-14 岁儿童的发病率较高。新生儿的影响有限,这可以解释为 2022 年怀孕期间和 11 个月大时的高疫苗接种率,分别为 85%和 94.1%。应该考虑在青春期前接种第三剂加强疫苗,并提高孕妇的疫苗接种率,以控制未来的疫情。
