Evaluation of the Risk of Infection During Fever in Labor

* Fever during labor affects more than 8% of parturients. It is a heterogeneous entity and can be due to an infectious process, a side effect of a drug, or to labor itself (physiological hyperthermia). * It has been the subject of several retrospective studies and a few prospective studies with varying methodologies, definitions, and inclusion criteria. None have proposed a combined obstetric, neonatal, infectious disease, and microbiological analysis. * It raises concerns about the possibility of an emerging maternal (obstetric or otherwise) and/or fetal infection. * Analysis of the available literature does not clarify the exact frequency of these infections or the predictive factors for their occurrence. * It often justifies systemic antibiotic therapy, the modalities and benefits of which have never been evaluated. The investigators aim to conduct a prospective multicenter study to analyze fever during labor with a combined obstetric, infectious disease, pediatric, and microbiological perspective.
