Hantaviruses, transmitted to people by infected rodents, are part of the Bunyavirales order of viruses and can cause either hemorrhagic fever with renal syndrome (HFRS) or hantavirus pulmonary syndrome (HPS). Hantaviruses that cause HFRS are found throughout the world, while those that cause HPS, including the Sin Nombre hantavirus, are found in the Americas. Early symptoms of both HRFS and HPS include fever, chills, headaches, nausea, abdominal pain, and muscle soreness. A more developed infection causes coagulation, vasodilation, and changes in the capillary membranes, resulting in damage to lungs, kidneys, and other organs. Hantavirus diagnoses are most commonly confirmed by serology.
