For example, China, Russia and South Korea report several thousand cases a year.</p><p>In the Americas, Finland and France, there are several hundred cases annually.</p><p>Only certain strains of hantaviruses found exclusively in rodents -- rats, mice, and voles -- are transmitted to humans.</p><div><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/67fG4rjY7eA?&amp;pp=0gcJCd4KAYcqIYzv&amp;wmode=opaque&amp;rel=0" frameBorder="0" allowfullscreen="" class="fr-draggable"></iframe></span><br/></div><div><br/></div><div><strong> How dangerous are they?</strong></div><div><br/></div><p>Hantaviruses are split into two groups: viruses from the old world (Europe, Asia, Africa) and those from the new world (North, Central and South America).</p><p>For old world viruses, the mortality rate can be as high as 14 percent. However, in developed nations such as France, fatal cases are extremely rare and mainly affect people with pre-existing health conditions.</p><p>Some cases are asymptomatic or limited to body aches, an upset stomach and a mild cough. But rare cases can include kidney problems that can develop into acute but reversible renal failure.</p><p>In contrast, the lethality of new world viruses can exceed 40 percent. These cases can rapidly spread to lungs, leading to breathing issues or sometimes heart problems.</p><div><a href="https://www.abs-cbn.com/news/health-science/2026/5/4/explainer-what-is-hantavirus-1844">EXPLAINER: Spread by rodents, Hantavirus is potentially fatal, with no specific cure </a></div><div><br/></div><div><strong>What is the treatment? </strong></div><div><br/></div><div><span class="fr-video fr-deletable fr-fvc fr-dvb fr-draggable" contenteditable="false" draggable="true"><iframe width="640" height="360" src="https://www.youtube.com/embed/PQ8xI-kE7eU?&amp;wmode=opaque&amp;rel=0" frameBorder="0" allowfullscreen="" class="fr-draggable"></iframe></span>The faster people receive treatment, the better their prognosis.</div><p>Because there is no specific treatment for hantavirus, instead doctors aim to manage the symptoms.</p><p>If the virus severely affects the lungs, oxygen therapy in an intensive care unit may be necessary.</p><p>People who work in particular industries, such as forestry or farming, are particularly at risk.</p><p>Like any infection, the most at risk are the elderly, those with weaker immune systems, and people with pre-existing health problems.</p><div><br/></div><div><strong>Is it contagious? </strong></div><div><br/></div><p>It is still unknown whether this was an outbreak of the Andes virus. This is the only strain for which there are confirmed cases of human-to-human transmission, but this required close and prolonged contact -- for example, within a family.</p><p>Humans are mainly infected by inhaling aerosols contaminated by the saliva, droppings or urine of animals or through direct contact with faeces, or via bites or scratches.</p><p>For the cruise ship, there are two possible scenarios: human-to-human transmission or isolated infections before people boarded, for example if they took a trip together.</p><div><br/></div><div><strong>What could sequencing reveal? </strong></div><div><br/></div><p>Sequencing the virus from an infected passenger on the ship will identify what strain of hantavirus is involved.</p><p>Because the ship left from Ushuaia in southern Argentina, the Andes virus is suspected because it circulates there.</p><p>However, if it is a different new world strain, for example one called Sin Nombre, which only circulates in North America, contamination in South America can be ruled out.</p><p>If a new world hantavirus is being transmitted between humans on this ship, that would be unprecedented, to my knowledge.</p>
