Brief summary
Hantaviruses are emerging pathogens responsible for hemorrhagic fever with renal syndrome. Severity risks factors aren't consensual in litterature, mostly related to scandinavian cohorts. A prognostic score was created to help patient's orientation in healthcare system but wasn't independantly validated (Hentzien, Emerging infectious diseases 2018). This retrospective cohort of hantavirus infected hospitalized adults patients in the north-eastern quarter of France between 2013 and 2022 will specify the kidney damage during infection and risk factors for a severe form (defined par acute kidney injury KDIGO 3). The previous prognostic score performance will be evaluated in this cohort.
