Usually, (<a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC8621010\" target=\"_blank\" rel=\"noopener\">farmers and forestry workers<\/a>) are most at risk of exposure to infected rodents. <\/p>\n\n<p>There are at least <a href=\"https:\/\/ictv.global\/taxonomy\" target=\"_blank\" rel=\"noopener\">38 recognised species<\/a> of hantavirus across the world, <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC7438779\/\" target=\"_blank\" rel=\"noopener\">24 of which cause disease in humans<\/a>. It\u2019s considered a rare virus but it\u2019s also likely to be underdiagnosed in many areas of the world because the initial symptoms can be mistaken for cold and flu-like viral infections.<\/p>\n\n<figure>\n            <iframe loading=\"lazy\" width=\"440\" height=\"260\" src=\"https:\/\/www.youtube.com\/embed\/4drq0Wb8pQc?wmode=transparent&amp;start=0\" frameborder=\"0\" allowfullscreen=\"\"><\/iframe>\n            \n          <\/figure>\n\n<p>Hantaviruses are typically divided into <a href=\"https:\/\/www.gov.uk\/guidance\/hantaviruses\" target=\"_blank\" rel=\"noopener\">\u201cold-world\u201d and \u201cnew-world\u201d<\/a> types. Old world hantaviruses are found in Europe and Asia, including the <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC2600231\/\" target=\"_blank\" rel=\"noopener\">puumala hantavirus<\/a>, which uses the bank vole as its host, and the <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC2662651\/\" target=\"_blank\" rel=\"noopener\">Hantaan virus and Seoul virus<\/a>, carried by the striped field mouse and the common brown rat. These hantaviruses cause haemorrhagic fever with renal syndrome (HFRS) \u2013 bleeding from various areas of the body and varying degrees of kidney impairment. Estimated to affect <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC6776365\/\" target=\"_blank\" rel=\"noopener\">150,000 people<\/a>  annually, this condition is usually <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S1201971216000047\" target=\"_blank\" rel=\"noopener\">reversible<\/a>. Some patients may develop <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/B978070203468850225X\" target=\"_blank\" rel=\"noopener\">nephropathia epidemica<\/a> \u2013 a milder form of the virus.  <\/p>\n\n<p>New world hantaviruses, found in North and South America, result in hantavirus pulmonary syndrome (HPS), which tends to be more severe than HFRS. It affects the lungs and heart, impairing the delivery of oxygen around the body. In North America, the most common type of hantavirus is the <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC10669331\/\" target=\"_blank\" rel=\"noopener\">sin nombre virus<\/a> spread by the deer mouse. In South America the <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC1933362\/\" target=\"_blank\" rel=\"noopener\">andes virus<\/a>, often carried by the long-tailed pygmy rice rat, is most common.<\/p>\n\n<h2 id=\"hantavirus-transmission\">Hantavirus transmission<\/h2>\n\n<p>The disease is caused by inhaling rodent <a href=\"https:\/\/www.cdc.gov\/hantavirus\/hcp\/clinical-overview\/hps.html\" target=\"_blank\" rel=\"noopener\">faeces, urine or saliva<\/a> \u2013 often from disturbing rodent nests and droppings <a href=\"https:\/\/www.health.ny.gov\/diseases\/communicable\/hantavirus\/fact_sheet.htm#:%7E:text=How%20is%20hantavirus%20spread?,from%20one%20person%20to%20another.\" target=\"_blank\" rel=\"noopener\">while cleaning<\/a>. More rarely, hantavirus is transmitted by <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/15602208\/\" target=\"_blank\" rel=\"noopener\">bites<\/a> and scratches from <a href=\"https:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/mm5346a3.htm\" target=\"_blank\" rel=\"noopener\">infected animals<\/a>. <\/p>\n\n<p>A small number of studies have documented <a href=\"https:\/\/www.nejm.org\/doi\/full\/10.1056\/NEJMoa2009040\" target=\"_blank\" rel=\"noopener\">human-to-human spread<\/a> of the andes strain in South America, but a <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC9574657\/\" target=\"_blank\" rel=\"noopener\">systematic review<\/a> of the research didn\u2019t find enough evidence of human-to-human transmission.<\/p>\n\n<p>The incubation period of hantavirus is relatively long, <a href=\"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/62\/6\/article-p714.xml\" target=\"_blank\" rel=\"noopener\">typically two to three weeks<\/a>, but can be as long as <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC3291207\/\" target=\"_blank\" rel=\"noopener\">six weeks<\/a>. This may be why cases are underreported \u2013 patients may forget the potential exposure event. Diagnosis is usually based on symptoms and history, although laboratory tests can <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/9114393\/\" target=\"_blank\" rel=\"noopener\">detect antibodies to hantavirus<\/a> in human serum.<\/p>\n\n<p>The virus causes a change in the <a href=\"https:\/\/www.frontiersin.org\/journals\/microbiology\/articles\/10.3389\/fmicb.2014.00727\/full\" target=\"_blank\" rel=\"noopener\">permeability of the cells that line blood vessels<\/a> so that fluid leaks out in places it shouldn\u2019t, such as the lungs and kidneys. It also <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0049384815301353\" target=\"_blank\" rel=\"noopener\">reduces the number of platelets<\/a> in the blood, reducing blood clotting so that blood leaks from organs and vessels. The hantavirus also appears to <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC8207335\/\" target=\"_blank\" rel=\"noopener\">prevent<\/a> apoptosis \u2013 when the body kills cells in response viral infection \u2013 so the body is unable to get rid of infected cells as efficiently, which prolongs the virus.<\/p>\n\n<p>The severity of the virus depends on a number of factors, including age and genetic predisposition. People over the age of 70 are <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK560660\/\" target=\"_blank\" rel=\"noopener\">most likely to die<\/a> of hantavirus, while some <a href=\"https:\/\/www.clinicalmicrobiologyandinfection.com\/article\/S1198-743X(15)00536-4\/fulltext\" target=\"_blank\" rel=\"noopener\">human leukocyte antigens<\/a>\u2013 the immune system markers that check which cells belong in your body and which do not \u2013 show an increased risk of severe disease. <\/p>\n\n<p>It isn\u2019t known how long immunity following hantavirus infection lasts, but <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC9217627\/\" target=\"_blank\" rel=\"noopener\">immunoglobulin G antibodies<\/a> \u2013 a type of protein that helps the body fight infections from viruses and bacteria \u2013 are likely to protect against subsequent symptomatic infection from the same strain. However, given the large number of hantavirus species, having had one form would be unlikely to protect against catching a different form.<\/p>\n\n<h2 id=\"symptoms\">Symptoms<\/h2>\n\n<p>Infection with either old or new world strains start with similar viral symptoms: fever, headache, fatigue, muscle pains, abdominal issues including nausea, vomiting, diarrhoea and abdominal pains. The old and new strains have different disease progression. Both strains should be treated promptly to reduce risk of death. <\/p>\n\n<figure>\n            <iframe loading=\"lazy\" width=\"440\" height=\"260\" src=\"https:\/\/www.youtube.com\/embed\/9CnkfErAHgw?wmode=transparent&amp;start=0\" frameborder=\"0\" allowfullscreen=\"\"><\/iframe>\n            \n          <\/figure>\n\n<p>In old-world infections leading to HFRS, patients move from the generic symptoms to low blood pressure and then reduced urinary output. Patients may need <a href=\"https:\/\/academic.oup.com\/jid\/article-abstract\/167\/3\/614\/877698?redirectedFrom=fulltext\" target=\"_blank\" rel=\"noopener\">dialysis<\/a> to protect the kidneys. Those infected will then experience <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S1201971216000047\" target=\"_blank\" rel=\"noopener\">increased urinary output<\/a> to clear the excess fluid collected in the previous stage of the disease. Finally, patients enter the <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK560660\/\" target=\"_blank\" rel=\"noopener\">convalescent phase<\/a> with fatigue and muscle pains. <\/p>\n\n<p>In HPS from new-world hantavirus strains, symptoms usually appear within eight weeks of exposure. Three to five days of generic symptoms are followed by rapid deterioration as fluid fills the lungs making breathing difficult. Many patients <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S088394412400354X\" target=\"_blank\" rel=\"noopener\">require mechanical ventilation<\/a> such as <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC5135534\/\" target=\"_blank\" rel=\"noopener\">extracorporeal membrane oxygenation<\/a> \u2013 a kind of life support where blood is pumped outside of the body to a heart-lung machine. In the final stage of the disease, urine output will increase significantly as the body attempts to expel excess fluid. With early treatment, most people with HPS fully recover with no lasting effects \u2013 but mortality rate can be as <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC2810485\/\" target=\"_blank\" rel=\"noopener\">high as 40%<\/a>. <\/p>\n\n<h2 id=\"treatments\">Treatments<\/h2>\n\n<p>Treatment is targeted towards symptom management with oxygen therapy. Antiviral medication ribavirin has shown in trials to be <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/34203936\/\" target=\"_blank\" rel=\"noopener\">more beneficial for HFRS<\/a> <a href=\"https:\/\/www.cdc.gov\/hantavirus\/hcp\/clinical-overview\/hps.html\" target=\"_blank\" rel=\"noopener\">than HPS<\/a>. A <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/33131933\/\" target=\"_blank\" rel=\"noopener\">hantavirus vaccine trailed<\/a> in South Korea generated a good immune response and was well tolerated for prevention of HFRS but wider results are unclear.<\/p>\n\n<p>As always, prevention is better than cure and the most effective way to prevent hantavirus infection in humans is to keep surroundings free from rodents. But, this is <a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.ads6782\" target=\"_blank\" rel=\"noopener\">easier said than done<\/a> \u2013 so cleaning with disinfectant is essential to ensure areas are <a href=\"https:\/\/www.cdc.gov\/healthy-pets\/rodent-control\/clean-up.html\" target=\"_blank\" rel=\"noopener\">free of rodent fluids and faeces<\/a>. Allow disinfectant or bleach to soak the area for at least five minutes before cleaning with absorbent materials. Gloves and a mask, of course, should be worn at all times.<!-- Below is The Conversation's page counter tag.
