Korean hemorrhagic fever

Korean hemorrhagic fever, also known as hemorrhagic nephroso-nephritis, is a form of hemorrhagic fever with renal syndrome (HFRS) caused by the Hantaan virus. This virus is carried by the striped field mouse, prevalent in Asia and Europe. HFRS typically develops within one to two weeks of exposure and can cause fever, headache, blurred vision, nausea, internal bleeding, and kidney failure. Korean hemorrhagic fever has a fatality rate of 5 to 15 percent. Hantaviruses are RNA viruses transmitted to humans through contact with infected rodent excreta, often when human activity alters natural habitats. Prevention involves controlling rodent infestations and limiting exposure to rodent environments.12
