Hantavirus

▲ Hot Trend score: 80 Published: May 31, 2026

A rare Andes hantavirus outbreak tied to the cruise ship MV Hondius — 13 cases, at least 3 deaths, passengers from 23 countries — has the world suddenly Googling a disease most people thought only lurked in dusty barns.

The context

An outbreak of Andes hantavirus has been linked to the expedition cruise ship MV Hondius, which departed Ushuaia, Argentina on 1 April 2026 with 147 people aboard — 86 passengers and 61 crew from 23 countries. The vessel visited some of the world’s most remote locations: Antarctica, South Georgia, Tristan da Cunha, St Helena, and Ascension Island. The WHO was officially notified on 2 May 2026.

As of 26 May 2026, there are 13 cases (11 confirmed, 2 probable) and at least 3 deaths. The CDC took the unusual step of repatriating 18 passengers to the Nebraska Quarantine Unit on 10 May for 42-day monitoring — a move that signals institutional seriousness without triggering mass panic.

What makes this outbreak scientifically significant is the pathogen itself. Andes virus is the only hantavirus known to transmit person-to-person, though that transmission requires prolonged, close contact and is still considered rare. Every other hantavirus strain infects humans exclusively through contact with infected rodents or their waste — never from another human.

Health authorities are clear: risk to the general public is very low. The outbreak is being managed within a contained, traceable group. But the combination of a luxury cruise ship, remote destinations, a deadly virus, and international passengers from 23 countries is exactly the kind of story that sends search volumes spiking.

The questions flooding search engines right now mix legitimate concern about the outbreak with longer-standing public curiosity about hantavirus — rodent exposure, cleaning risks, and survival odds. Here’s what you actually need to know.

People also ask

How did Hackmans wife get hantavirus?#
This question conflates two separate stories. Gene Hackman's wife, Betsy Arakawa, died in early 2025 — the cause of death reported in widely covered news was hantavirus pulmonary syndrome, almost certainly contracted through exposure to infected rodent droppings or urine at their New Mexico property. The current MV Hondius cruise ship outbreak is a completely unrelated event involving Andes hantavirus. The two cases have nothing to do with each other.
How did Gene Hackman's wife catch hantavirus?#
Based on widely reported accounts, Betsy Arakawa is believed to have been exposed to hantavirus through contact with infected rodent material — droppings, urine, or nesting debris — at their New Mexico home, a region where Sin Nombre hantavirus is endemic in deer mouse populations. No person-to-person transmission was involved; the Sin Nombre strain, unlike Andes virus, spreads only from rodents to humans. The precise circumstances were not publicly confirmed in full detail.
Why hantavirus so deadly?#
Hantavirus kills because it triggers a catastrophic immune overreaction. In Hantavirus Pulmonary Syndrome (HPS), the virus causes the lungs to fill with fluid — patients essentially drown from the inside. There is no approved antiviral treatment, so medicine can only support the body while it fights. The case fatality rate for HPS runs around 38% according to the CDC, making it one of the deadliest infections a person can catch in the Americas.
Can you survive hantavirus?#
Yes — but your odds depend heavily on how fast you get to intensive care. Roughly 62% of HPS patients in the U.S. survive, per CDC data, with early hospitalization and aggressive respiratory support making the biggest difference. There is no specific cure; survival hinges on managing lung failure until the immune response subsides. The earlier the diagnosis, the better the outcome.
How common is the hantavirus?#
Extremely rare. The CDC has recorded fewer than 850 confirmed HPS cases in the United States since surveillance began in 1993 — that's roughly 25–30 cases per year across the entire country. Globally, case counts remain in the hundreds annually. It is not a disease you are statistically likely to encounter, even in rural areas where carrier rodents live.
What mice carry hantavirus?#
In North America, the primary culprit is the **deer mouse** (*Peromyscus maniculatus*), the main carrier of Sin Nombre virus — the strain responsible for most U.S. HPS cases. The white-footed mouse, cotton rat, and rice rat also carry other hantavirus strains in specific regions. Each hantavirus strain is tightly linked to one or two rodent reservoir species.
How do I catch hantavirus?#
Almost all human infections happen through inhaling aerosolized particles from infected rodent droppings, urine, or saliva — most often when disturbing old nests or droppings in enclosed spaces like cabins, sheds, or crawl spaces. You can also be infected through a direct bite or, more rarely, by touching contaminated material and then touching your mouth or nose. The sole exception is Andes virus (linked to the current cruise ship outbreak), which can also spread person-to-person through very close, prolonged contact.
Does hantavirus live in old droppings?#
Yes. Hantavirus can remain viable in dried rodent droppings, urine, and nesting material for days to weeks, depending on temperature and humidity — the CDC notes the virus survives longer in cool, shaded environments. This is exactly why sweeping or vacuuming old droppings is so dangerous: it launches infectious particles into the air you breathe. Always treat old rodent material as potentially live.
What is the very first symptom of hantavirus?#
The earliest symptoms are deceptively generic: fever, severe fatigue, and muscle aches — especially in the thighs, hips, and back — typically appearing 1–8 weeks after exposure. Some people also get headaches, dizziness, chills, and stomach upset. There is nothing at this stage to distinguish it from flu, which is part of why it gets missed early. The dangerous respiratory phase — shortness of breath, cough — hits 4–10 days later and is a medical emergency.
What state has the highest rate of hantavirus?#
New Mexico consistently leads the U.S. in hantavirus cases, followed closely by Colorado, Arizona, and Utah — the Four Corners region is considered the epicenter of Sin Nombre hantavirus activity in America. The combination of dense deer mouse populations, rural living, and adobe-style structures that rodents easily infiltrate drives the elevated case count. The CDC's HPS case map makes this geographic cluster unmistakable.
What US states have hantavirus?#
Hantavirus has been reported in **34 U.S. states**, but cases are heavily concentrated in the rural West and Southwest — New Mexico, Colorado, Arizona, Utah, California, Montana, and Washington account for the bulk. Cases have also been documented in Texas, the Dakotas, and scattered eastern states. The short answer: if deer mice live there, the virus can be there.
How long can mouse droppings carry hantavirus?#
The CDC states that hantavirus in droppings, urine, or nesting material can remain infectious for days to weeks under typical indoor conditions — potentially longer in cool, damp, and shaded spaces. Direct sunlight and heat degrade the virus faster. The honest bottom line: don't try to calculate whether the droppings are "old enough" to be safe. Treat every rodent mess as live and clean it accordingly.
How many people died on the cruise ship with hantavirus?#
As of 26 May 2026, at least **3 people have died** in the MV Hondius Andes hantavirus outbreak, according to verified WHO and public health reporting. There are 13 total cases (11 confirmed, 2 probable) among the 147 people who were aboard. The situation is being actively monitored and the death toll could change; check WHO and CDC updates for the latest figures.
Do all rats carry hantavirus?#
No. Only specific rodent species carry specific hantavirus strains, and common urban rats (*Rattus norvegicus* and *Rattus rattus*) are not significant carriers of the hantaviruses that cause HPS in the Americas. The main North American threat comes from deer mice and related species. That said, some Old World rat species carry other hantaviruses (like Seoul virus), so "all rats are clean" is not the right conclusion either — just that the risk profile is species-specific.
What U.S. states have hantavirus?#
Cases have been documented in **34 states**, with the overwhelming majority in the rural West and Southwest: New Mexico, Colorado, Arizona, Utah, California, Montana, Washington, and the Dakotas top the list. The Four Corners region — where New Mexico, Colorado, Arizona, and Utah meet — is the national hotspot. For the full state-by-state breakdown, the CDC's HPS surveillance page is the authoritative source.
Do most rats carry hantavirus?#
No. The framing of "most rats" carrying hantavirus is wrong. Hantavirus carriage is species-specific and even within a carrier species, not every individual animal is infected. In North America, deer mice are the primary vector — not rats. Urban rat populations are not considered a meaningful hantavirus risk by the CDC. The concern is concentrated in wild rodent species in rural and semi-rural environments.
What are the first symptoms of hantavirus?#
Early-stage HPS looks almost identical to influenza: **fever, deep fatigue, and intense muscle aches** (particularly in large muscle groups like thighs and back), often with headache, chills, and sometimes nausea or abdominal pain. This phase lasts 3–5 days before — in severe cases — transitioning rapidly to respiratory distress. Anyone with these symptoms who has recently been around rodents or rodent habitats should tell their doctor immediately. Do not wait for breathing problems to seek care.
How to avoid hantavirus when cleaning?#
The CDC's protocol is specific and non-negotiable: **never sweep or vacuum rodent droppings** — it aerosolizes the virus. Instead, wear rubber gloves and an N95 respirator (minimum), thoroughly soak the affected area with a bleach solution (1 part bleach to 9 parts water) or a disinfectant, let it sit for 5 minutes, then wipe it up with paper towels and bag everything. Air out the space for at least 30 minutes before entering. This is not a job for a dust mask and a broom.
How many people are on the cruise ship with hantavirus?#
The MV Hondius had **147 people aboard** when it departed Ushuaia on 1 April 2026 — 86 passengers and 61 crew members from 23 countries. Of those, 13 have been identified as cases (11 confirmed, 2 probable) as of 26 May 2026, and 18 passengers were repatriated by the CDC to the Nebraska Quarantine Unit for 42-day monitoring. Health authorities stress the risk to the broader public remains very low.
In what states has hantavirus been found?#
Hantavirus has been identified in **34 U.S. states**, though it is far from evenly distributed. The clear concentration is in the rural West and Southwest — New Mexico, Colorado, Arizona, Utah, California, Montana, Washington, and the Dakotas are the states where cases cluster. Cases in eastern states are documented but rare. The CDC maintains an up-to-date case map on its HPS surveillance page.
