The Neutrophil/Lymphocyte Ratio Was Identified as a Marker of Severe Influenza During the 2024-2025 Outbreak in France.

ABSTRACT:

Background/objectives

Influenza continues to cause high morbidity and mortality rates worldwide, inflicting a major burden on the public health system. There is little data available on the 2024-2025 seasonal outbreak. Moreover, biomarkers for rapidly identifying subjects at higher risk for severe forms are needed.
