It is mainly spread through contact with infected rodents (like mice, rats etc), usually when a person breathes in tiny airborne particles contaminated with rodent urine, saliva, or droppings. Although hantavirus infections are relatively uncommon worldwide, they can be extremely dangerous. The fatality rate of hantavirus varies by region, ranging from less than 1% to 15% in Asia and Europe and reaching up to 50% in the Americas. Globally, experts estimate that between 10,000 and 100,000 hantavirus infections occur each year, with the highest burden reported in Asia and Europe1<\/a>,2<\/a><\/sup>.<\/p>\n\n\n\nRecently, hantavirus has gained global attention following a deadly outbreak reported on a cruise ship in the Atlantic Ocean on May 2, 2026. According to the World Health Organization (WHO), the outbreak was linked to the Andes virus, known to cause hantavirus pulmonary syndrome (HPS), a severe respiratory illness that can rapidly progress and become life-threatening3<\/a><\/sup>. The incident has raised concerns about awareness, early diagnosis, and preventive measures against this dangerous infection.<\/p>\n\n\n\nIn this blog, we will discuss what hantavirus is, its symptoms, causes, modes of transmission, risk factors, and the most effective ways to prevent infection.<\/p>\n\n\n\n<\/span>What is Hantavirus?<\/strong><\/span><\/h2>\n\n\n\nHantaviruses are a family of viruses that are commonly associated with rodents belonging to the Cricetidae family, which includes voles, lemmings, and New World mice and rats, as well as Muridae rodents such as Old World mice and rats1<\/a><\/sup>.<\/p>\n\n\n\n\nDid You Know?<\/strong><\/p>\n\n\n\n\nHantavirus was first discovered in 1978 near the Hantan River in South Korea after scientists isolated the virus from a field rodent (Apodemus agrarius).

Although rare, hantavirus infection can worsen quickly and cause serious complications if not identified and managed early. Since there is currently no specific antiviral treatment or approved vaccine for hantavirus, prevention remains the most effective way to reduce the risk of infection.<\/p>\n\n\n\nAvoiding contact with rodents, maintaining proper hygiene, practicing safe cleaning methods, and seeking timely medical attention for flu-like symptoms after possible rodent exposure are essential steps in protecting against hantavirus disease. In addition to this, increased awareness and early diagnosis can play a crucial role in improving outcomes and preventing severe complications.<\/p>\n\n\n\nAlso Read:<\/em><\/strong> Smog: What Is It, Causes and Ways To Protect Yourself From It<\/a><\/em><\/strong><\/p>\n\n\n\n

Recently, hantavirus has gained global attention following a deadly outbreak reported on a cruise ship in the Atlantic Ocean on May 2, 2026. According to the World Health Organization (WHO), the outbreak was linked to the Andes virus, known to cause hantavirus pulmonary syndrome (HPS), a severe respiratory illness that can rapidly progress and become life-threatening3<\/a><\/sup>. The incident has raised concerns about awareness, early diagnosis, and preventive measures against this dangerous infection.<\/p>\n\n\n\nIn this blog, we will discuss what hantavirus is, its symptoms, causes, modes of transmission, risk factors, and the most effective ways to prevent infection.<\/p>\n\n\n\n<\/span>What is Hantavirus?<\/strong><\/span><\/h2>\n\n\n\nHantaviruses are a family of viruses that are commonly associated with rodents belonging to the Cricetidae family, which includes voles, lemmings, and New World mice and rats, as well as Muridae rodents such as Old World mice and rats1<\/a><\/sup>.<\/p>\n\n\n\n\nDid You Know?<\/strong><\/p>\n\n\n\n\nHantavirus was first discovered in 1978 near the Hantan River in South Korea after scientists isolated the virus from a field rodent (Apodemus agrarius).

The two major hantavirus infections mentioned below mainly impact the lungs or the kidneys:<\/p>\n\n\n\n\nHPS: <\/strong>This is a severe respiratory illness mainly found in North and South America. It is commonly caused by the Sin Nombre type of hantavirus, which is usually spread by deer mice in North America, although different rodents may spread the virus in other regions. The infection can cause capillary leakage (leakage of fluid from small blood vessels), leading to fluid buildup in the lungs, severe breathing difficulties, and respiratory failure. The Andes virus is one of the viruses causing HPS2<\/a>,5<\/a><\/sup>.<\/li>\n\n\n\nHemorrhagic Fever With Renal Syndrome (HFRS):<\/strong> This disease is more commonly seen in Europe and Asia and mainly affects the kidneys and blood vessels.
