A Growing Public Health Problem in Europe with Potential Severe Renal Involvement.

Dengue is an arboviral infection transmitted by the mosquito of the Aedes genus, widespread especially in tropical and subtropical regions but now with worldwide involvement. Cases of contagion are also progressively increasing in Europe, and the differential diagnosis with other infections is not always easy. Renal involvement with acute renal failure is possible and caused by the direct action of the virus, hemodynamic instability, rhabdomyolysis, or acute glomerular damage. In patients most at risk of renal involvement, there is high morbidity and mortality, with more extended hospital stays and follow-ups over time, which increases the burden on healthcare systems. Knowledge of this infection by nephrologists is essential for reducing morbidity, mortality, and, therefore, healthcare costs.
