Although uncommon, the infection can lead to severe respiratory or kidney-related complications in some cases.<\/p><p data-start=\"301\" data-end=\"417\">Understanding how hantavirus spreads and recognising its symptoms early can help reduce the risk of serious illness.<\/p><h2 data-section-id=\"1ki4prn\" data-start=\"419\" data-end=\"441\">What is hantavirus?<\/h2><p data-start=\"443\" data-end=\"620\">Hantavirus refers to a group of viruses carried primarily by rodents. Humans can become infected after exposure to contaminated urine, droppings or saliva from infected rodents.<\/p><p data-start=\"622\" data-end=\"940\">Different strains of hantavirus exist around the world. In the Americas, the virus is more commonly linked to Hantavirus Pulmonary Syndrome (HPS), a severe illness affecting the lungs. In Europe and Asia, some strains are associated with haemorrhagic fever with renal syndrome (HFRS), which mainly affects the kidneys.<\/p><h2 data-section-id=\"1cy7n4o\" data-start=\"942\" data-end=\"970\">How is hantavirus spread?<\/h2><p data-start=\"972\" data-end=\"1106\">Hantavirus is most commonly spread when people breathe in tiny airborne particles contaminated with rodent urine, droppings or saliva.<\/p><p data-start=\"1108\" data-end=\"1200\">This can happen when cleaning or entering places where rodents have been present, including:<\/p><ul data-start=\"1202\" data-end=\"1280\"><li data-section-id=\"178kxnl\" data-start=\"1202\" data-end=\"1209\">Sheds<\/li><li data-section-id=\"lxyn2k\" data-start=\"1210\" data-end=\"1219\">Garages<\/li><li data-section-id=\"1woc32o\" data-start=\"1220\" data-end=\"1228\">Attics<\/li><li data-section-id=\"atix25\" data-start=\"1229\" data-end=\"1244\">Storage rooms<\/li><li data-section-id=\"1uy0iws\" data-start=\"1245\" data-end=\"1253\">Cabins<\/li><li data-section-id=\"1wpi3zk\" data-start=\"1254\" data-end=\"1280\">Poorly ventilated spaces<\/li><\/ul><p data-start=\"1282\" data-end=\"1316\">The virus may also spread through:<\/p><ul data-start=\"1318\" data-end=\"1480\"><li data-section-id=\"17naiu1\" data-start=\"1318\" data-end=\"1362\">Direct contact with rodents or their waste<\/li><li data-section-id=\"11d6f8j\" data-start=\"1363\" data-end=\"1431\">Touching contaminated surfaces and then touching the mouth or nose<\/li><li data-section-id=\"1slb8xv\" data-start=\"1432\" data-end=\"1460\">Rodent bites in rare cases<\/li><li data-section-id=\"c910lf\" data-start=\"1461\" data-end=\"1480\">Contaminated food<\/li><\/ul><p data-start=\"1482\" data-end=\"1650\">Most hantavirus strains do not spread from person to person. Human transmission is extremely rare and has only been documented with specific strains in certain regions.<\/p><h2 data-section-id=\"98jecd\" data-start=\"1652\" data-end=\"1691\">What are the symptoms of hantavirus?<\/h2><p data-start=\"1693\" data-end=\"1870\">Symptoms usually appear between 1 and 8 weeks after exposure.
