Characteristics of the 2023-2024 epidemic in adults, Southeast France.

Objectives: Analysis of current 2023-2024 (Mp) infection characteristics in adults.

Methods: A retrospective case series analysis was performed on polymerase chain reaction-positive adult patients admitted to the University Hospital of Marseille from April 2017 to June 2024. Clinical presentations, treatments, and outcomes were assessed.

A permutation test based on the restricted mean survival time for comparison of net survival distributions in non-proportional excess hazard settings.

Net survival is used in epidemiological studies to assess excess mortality due to a given disease when causes of death are unreliable. By correcting for the general population mortality, it allows comparisons between regions or periods and thus evaluation of health policies. The Pohar-Perme non-parametric estimator of net survival has been recently proposed, soon followed by an appropriate log-rank-type test.
