[Renal failure in a couple caused by Puumala hantavirus].

In Scandinavia Puumala hantavirus causes nephropathia epidemica (NE), characterised by an acute debut of fever, headache, increasing back and abdominal pain, thrombocytopenia, increasing azotemia parameters, as well as microscopic haematuria and mild proteinuria. In some cases transitory myopia can be found. The diagnosis is made with a relevant clinical history and serology, and in most cases a kidney biopsy is not necessary. There is a risk of missing cases of NE as in this case, where a couple became infected by Puumala Hantavirus in a high-risk area but became ill in an area with a low prevalence.
