U ovom članku prikazan je slučaj prethodno zdravog 42-godišnjeg drvosječe koji je obolio od hemoragijske vrućice s bubrežnim sindromom (HVBS) ili epidemijske nefropatije. Hemoragijska vrućica s bubrežnim sindromom akutna je infektivna bolest uzrokovana hantavirusima, a glavni rezervoar su glodavci (riđa voluharica i miševi). U Hrvatskoj postoje dva tipa hantavirusa: Puumala i Dobrava-Belgrade. Puumala virus je najčešći oblik hantavirusa u našoj zemlji. Uzročnik je blagog i srednje teškog oblika HVBS. Čovjek se najčešće zarazi udisanjem aerosola koje sadržavaju virus ili drugim kontaminiranim izlučevinama (mokraćom, stolicom, slinom) inficiranih glodavaca. Osnovna značajka HVBS je oštećenje bubrežne funkcije različitog stupnja sve do bubrežnog zatajenja. Česti simptomi su vrućica, glavobolja, bolovi u leđima i bolovi u trbuhu. Dobrava-Belgrade tip virusa uzrokuje težu kliničku sliku s krvarenjima, plućnim i neurološkim simptomima. Tijek HVBS može se podijeliti u pet faza, a to su: febrilna, hipotenzivna, oligurijska, poliurijska i rekonvalescentna faza. Ne postoji specifično liječenje za HVBS, stoga je vrlo važna rana dijagnostika i adekvatno simptomatsko liječenje.PA case of previously healthy 42-year-old woodman who saffered from haemorrhagic fever with renal syndrome (HFRS), also called epidemic nephropathy, is presented. Haemorrhagic fever with renal syndrome belongs to emerging infections. It is caused by hantaviruses. Those viruses are transmitted to humans by rodents, bank vole and mice being the main reservoirs. Two types of hantaviruses are identified in Croatia: Puumala virus and Dobrava-Belgrade virus. Puumala virus is the most frequent hantavirus in our country. It causes mild to moderate form of HFRS. People are infected by inhaling aerosolised virus particles shed through urine, faeces or saliva. The main characteristic of HFRS is renal dysfunction or renal failure with rare haemorrhagic anifestations. Other frequent symptoms are fever, headache, backpain and gastrointestinal symptoms. Dobrava-Belgrade type of virus causes more severe disease with bleedings, pulmonary symptoms and neurological complications. The course of HFRS is divided into five stages: febrile, hypotensive, oliguric, diuretic and convalescent phase, but these phases are not always clinically evident. There is no specific antiviral therapy. Therefore, it is very important that family physicians working in the regions where HFRS usually occures, have it in mind in cases of patients with sudden onset of fever or flu-like symptom
