Abstract

We report a 19-fold increase in 2024 of qPCR diagnoses of Chlamydia pneumoniae infections in Marseille, Southern France, with 37 cases versus 10 between 2018-2023. These mostly affected children, and young adults. We obtained four C. pneumoniae genomes, all of serotype ST16, suggesting an epidemic circulation in our geographical area.
