Brief summary

Unprecedented changes in human-environment interactions and increasing disruptions to ecosystems and the climate have contributed to the emergence of infectious diseases (Emerging Infectious Diseases, EIDs). Advances in the treatment of cancers, malignant haematological disorders and immune-mediated inflammatory diseases are also contributing to the creation of new infectious risks among immunocompromised patient populations. The COVID-19 pandemic has shown that structuring research prior to any outbreak is essential for the rapid implementation of responses to the emergence of an EID. The unpredictability of an EID's occurrence necessitates the planning of research projects in advance. A key element in this planning is the development of a collection of biological samples, providing a structured and immediately deployable resource for conducting pathophysiological and therapeutic research aimed at: * Analyze the biological determinants of the microbe and the resulting infection * Develop new tools for identification and characterization * Study the factors (biomarkers/signatures) associated with individual patient susceptibility and response to treatment (personalized medicine) * Understand the pathophysiology of infection to identify new targets for diagnostic, curative and preventive treatment * Monitor the efficacy of curative and preventive treatments

Detailed description

COMETE consists in a prospective monocenter longitudinal non-interventional study allowing the collection of biological samples from individuals or patients investigated in the context of an emerging infectious disease or one at risk of emergence due to exposure or suggestive symptomatology, whether the infection is ultimately ruled out or confirmed, and whether or not they have received curative or preventive treatment for this infection. Visits: The initial visit (inclusion) and follow-up visits will take place as part of the patient's routine care, assessing their disease status or the curative or preventive treatment received during either hospitalization or a consultation. During these visits, biological samples will be collected when sampling is planned as part of the care (for verification, suspicion, diagnosis, or monitoring), and then throughout the follow-up period as part of the care plan.
