We present the case of a young male diagnosed with haemorrhagic fever with renal syndrome. The patient presents himself with flu-like symptoms, with a rapid aggravation of the clinical and biological status towards a hemorrhagical syndrome and acute renal failure. Antibodies anti-Hantavirus (ELISA method), confirmed a recent infection. Hantavirus, classified in the Bunyaviridae family may cause two clinical syndromes: haemorrhagic fever with renal syndrome and pulmonary hantaviral syndrome. Wild rodents serve as agent’s host.
