A person who came into contact with hantavirus on the Hondius cruise ship is to be brought to Dusseldorf for medical testing, a hospital in the western German city said on Wednesday. 

The University Hospital in Dusseldorf said the transportation and precautionary medical testing of the person would take place on Wednesday. It added that the person concerned is asymptomatic and presumed not to be infected with the virus. 

"This is a contact person with no confirmed evidence of a hantavirus infection. Admission is purely precautionary for medical evaluation," the hospital emphasized.

Three passengers of the Hondius - which is anchored off Cape Verde after sailing across the Atlantic from Argentina with just under 150 people on board - have died amid an outbreak of hantavirus. 

Another passenger has tested positive for the virus after returning to Switzerland.

According to the World Health Organization (WHO), three people suspected of having hantavirus have been evacuated from the cruise ship. WHO head Tedros Adhanom Ghebreyesus said they are on their way to receive medical treatment in the Netherlands.

It was initially unclear whether the person who is to be transported to Dusseldorf had been in contact with one of these three people. 

The WHO is working with the operators of the Hondius to closely monitor the health of passengers and crew and to arrange evacuations if necessary.  

"At this stage, the overall public health risk remains low," the WHO head wrote on X.

Human Spread Of Hantavirus Not Ruled Out On Cruise Ship


By Dominika Tomaszewska-Mortimer

Hantavirus victims on a ship in the Atlantic Ocean may have been infected prior to joining the cruise and human-to-human transmission on board cannot be ruled out – although it is rare – the World Health Organization (WHO) said on Tuesday.

The deadly disease outbreak has triggered an international public health response. Seven individuals of the 147 passengers and crew have been reported ill and three have died in what remains a fluid situation, WHO’s chief of Epidemic and Pandemic Preparedness and Prevention Dr Maria Van Kerkhove told reporters in Geneva.

“One patient is in intensive care in South Africa, although we understand that this patient is improving,” she said, while two patients still on board the ship, which is currently off the coast of Cabo Verde, are being prepared for medical evacuation to the Netherlands for treatment. 

Dr Van Kerkhove stressed that the situation is being closely monitored. As a precaution, passengers have been asked to remain in their cabins while disinfection and other public health measures are carried out. Medical teams from Cabo Verde are providing support on board the ship.

“The plan is, and our highest priority is, to medically evacuate these two individuals” to make sure that they receive the required care, she insisted. 

There are no other symptomatic patients on board. A third suspected case who reported a mild fever at one point “is currently doing well”, the WHO official said.

Spain cooperation

The ship is set to continue on to the Canary Islands. Ahead of arrival, Dr Van Kerkhove said that WHO is working with the Spanish authorities who “have said that they will welcome the ship to do a full epidemiologic investigation, full disinfection of the ship, and of course to assess the risk of the passengers”. 

Hantaviruses are carried by rodents and can cause severe disease in humans. Thousands of infections are estimated to occur each year. People usually get infected through contact with infected rodents or their urine, their droppings, or their sali

Discussing the suspected origins of the outbreak, Dr Van Kerkhove said that the initial patients, a husband and wife, boarded the boat in Argentina. 

“With the timing of the incubation period of hantavirus, which can be anywhere from one to six weeks, our assumption is that they were infected off the ship,” she said. “This was an expedition boat… many of the people on board were doing bird watching” and “seeing a lot of different wildlife.”

The cruise stopped at several islands off the coast of Africa, Dr Van Kerkhove continued, some of which “have a lot of rodents”. 

“There could be some source of infection on the islands as well for some of the other suspect cases,” she said. “However, we do believe that there may be some human-to-human transmission that’s happening among the really close contacts” such as the husband and wife and others who have shared cabins.

Past outbreak lessons

Transmission of infection between people is uncommon, but limited spread has been reported among close contacts in previous outbreaks of the Andes virus, which is part of the hantavirus group.

There are no specific treatments for hantavirus other than supportive care. 

“Typically, people will develop respiratory symptoms, so respiratory support is really important,” Dr Van Kerkhove said, stressing that some people require mechanical ventilation. Intensive care may be required, especially if the condition of patients deteriorates.

Directing her message at the people on the boat, where more than 20 nationalities are represented, the WHO official said: “We just want you to know we are working with the ship’s operators” and with the travellers’ countries of origin.

“We hear you. We know that you are scared,” she said. “We’re trying to make sure that the ship has as much information as they can…that you’re cared for and of course, that you get home safely.”


Hantavirus cruise highlights the environmental risks of ‘last chance tourism’, scientists warn

Trips to Antarctica “need to be regulated appropriately, as you would with any of the world’s sensitive and precious ecological sites,” says one expert.

Some of the most remote destinations on Earth are irreversibly melting away, giving rise to 'last chance tourism' - an industry built around the desire to see places like Antarctica before they disappear.

But a deadly outbreak of the rare hantavirus aboard a Dutch cruise ship has experts warning that tourists can inadvertently contaminate very fragile ecosystems.

Hantavirus is confirmed to have killed two people and suspected to have killed another onboard the MV Hondius, a cruise ship which left Argentina on 1 April and visited Antarctica and several isolated islands.

The ship has been at the centre of an international health scare since Saturday, after it was revealed that the rare disease, generally spread from infected rodents, was at the centre of an outbreak onboard the "ice-strengthened cruise ship".

The 107-metre polar explorer vessel is currently off the coast of Cape Verde, awaiting the evacuation of passengers who require medical attention. From there, the ship is hoping to sail to the Canary Islands but local authorities have not yet granted permission for the boat to dock there.

The Antarctic Peninsula is one of the fastest-warming places in the world

Tourism to the bottom of the world is soaring. Experts warn that with more visitors comes an increased risk of contamination, illness and other damage to the continent.

While visitor numbers are still small – in part due to the high costs and time it can take – they are growing so fast that scientists and environmentalists are sounding alarms.

Most expeditions head to the Antarctic Peninsula, one of the fastest-warming places in the world. From 2002 to 2020, roughly 149 billion metric tons (164 billion tons) of Antarctic ice melted per year, according to the National Aeronautics and Space Administration.

A common route is to voyage south from Argentina toward Antarctica before heading north up the coast of Africa – the same route taken by the cruise ship MV Hondius.

Bird flu has spread to Antarctica


Officials have not indicated any evidence of contamination from the MV Hondius.

However, flocks of migratory birds brought avian flu from South America to Antarctica in recent years, according to the US Centers for Disease Control and Prevention.

That outbreak prompted the International Association of Antarctica Tour Operators and others to harden rules for tourists’ conduct and hygiene to protect visitors from being contaminated.

To protect the fragile ecosystem from invasive species large and microscopic, visitors are told to stay away from animals and to avoid touching the ground with anything but their feet.

“There are rules that people are bound by when they’re heading south,” Nielsen said, describing her five voyages as a former guide. Crews and passengers use vacuums, disinfectants and brushes to scrub shoes and equipment clear of bugs, feathers, seeds and microbe-carrying dirt.

“Between the tongues and the laces of the boots you can find a lot of things,” she said.

Cruise ships have been struck by outbreaks of diseases like norovirus, which can spread quickly in a ship's close quarters. In 2020, a COVID-19 outbreak on the Diamond Princess turned the cruise ship into an incubator for the then-mysterious virus.

Hantavirus usually spreads by inhaling contaminated rodent droppings.
Explosive growth of trips to the southern continent

In 2024, more than 80,000 tourists touched down on the vast ice-cloaked continent and 36,000 viewed from the safety of ships, according to data collected by the International Association of Antarctica Tour Operators.

The International Union of Concerned Scientists estimates that tourism to Antarctica has grown tenfold in the past 30 years.

That number could rise further in the next decade as costs fall with more ice-capable hulls hitting the water and technological advances, says Hanne Nielsen, a senior lecturer of Antarctic law at the University of Tasmania. Her colleagues at the university estimate the annual figure could triple or quadruple to over 400,000 visits in that time.

The Hondius' island hopping cruise

WHO is investigating possible human-to-human transmission on the cruise ship, said Dr. Maria Van Kerkhove, WHO’s director of epidemic and pandemic preparedness. Officials suspect the first infected person likely contracted the virus before boarding, she said, and officials have been told there are no rats on board.

Antarctica is governed by the Antarctic Treaty, which in 1959 enshrined the territory as a scientific preserve used only for peaceful purposes. A series of rules that followed “aim to ensure that all visits, regardless of location, do not adversely impact the Antarctic environment or its scientific and aesthetic values,” according to the treaty’s secretariat.

Companies and scientific ventures voluntarily comply with biosecurity guidelines and submit environmental impact assessments for Antarctic operations.

The treaty was written when tourism numbers were much lower, Christian said.

“Activity needs to be regulated appropriately, as you would with any of the world’s sensitive and precious ecological sites,” Christian said from Hiroshima, Japan, where she was preparing for an Antarctic Treaty Consultative Meeting. There she'll join calls to strengthen protections for Antarctica's penguins, whales, seabirds, seals and krill — tiny creatures at the base of the food chain.

For now, the lure of the frozen frontier continues to draw visitors.

“You can put a footprint in Antarctica and it’s still there 50 years later,” Christian said.


Dairy Farms In California May Transmit H5N1 Virus Through Multiple Sources



By 

The H5N1 strain of highly pathogenic avian influenza H5N1 has been detected in over 700 herds of dairy cows in California, the largest dairy-producing state in the U.S. A study published in the open-access journal PLOS Biology led by Seema S. Lakdawala at Emory University School of Medicine, U.S. and Jason Lombard at Colorado State University, U.S. suggests that avian influenza (H5N1) is transmitted through multiple, previously unknown sources and that some H5N1 positive cows do not show clinical signs of infection.

H5N1 may spread on dairy farms through direct contact with unpasteurized milk, such as via contaminated milking equipment. However, the full picture of how the virus can be spread on farms with infected cows is unclear. In order to better understand transmission routes of avian flu on dairy farms, researchers took air, farm wastewater, and milk samples on fourteen dairy farms testing positive for H5N1 across two different California regions between October 2024 and January 2025. They tested all samples for the presence of virus and performed genome sequencing on detected virus to identify any genetic variants and mutations.

The researchers detected airborne virus from the exhaled breath of infected cows and in the dairy parlor, identified the presence of virus in the wastewater, and found a high prevalence of cows who tested positive for H5N1 despite being asymptomatic.

The extensive environmental contamination of infected dairy farms suggests a higher risk of viral spread from cows to humans and other animals. However, future studies are needed to validate these results as longitudinal sampling of individual cows was limited to only fourteen animals. Sampling across a larger sample of farms over a longer time period is also needed to support the findings.

Dr. Lakdawala notes, “Our data confirm the presence of infectious H5N1 virus in the air and reclaimed farm wastewater sites. In addition, we observed high viral loads and H5 antibodies in the milk of cows, including those without clinical signs, suggesting that multiple modes of H5N1 transmission likely exist on farms. These results identify additional sources of viral exposure for cows, peridomestic wildlife, and humans, highlighting the need for multiple mitigation strategies to reduce the spread of H5N1 within a herd and to humans.”

The authors add, “Detection of infectious virus in the air and waste streams on farms was surprising but highlights that there is a considerable amount of infectious virus on farms and multiple sources of infection exist.”

“Targeted interventions in the dairy parlors to reduce the amount of aerosols in the air and inactivation of sick milk prior to disposal will provide additional barriers to infection of farm workers and likely other farm animals.”

Drowned chicks and food scarcity: Emperor penguin and Antarctic fur seal now endangered

The primary drivers are shrinking sea ice and warming oceans driven by climate change.

By Rebecca Ann Hughes
Published on 

The primary drivers are shrinking sea ice and warming oceans driven by climate change.

The emperor penguin and Antarctic fur seal have been reclassified as ‘Endangered’ on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species.

Climate change in Antarctica is leading to changes in sea ice that are projected to halve the emperor penguin population by the 2080s, while reduced food availability has already driven a 50 per cent reduction in the Antarctic fur seal population since 2000.

“As countries prepare to gather at the Antarctic Treaty Consultative Meeting in May, these assessments provide essential data to inform decisions regarding this majestic continent and its awe-inspiring wildlife,” says Dr Grethel Aguilar, IUCN Director General.

“Antarctica’s role as our planet’s 'frozen guardian' is irreplaceable – offering untold benefits to humans, stabilising the climate and providing refuge to unique wildlife.”

Climate change brings bigger risk of penguin chicks drowning

The emperor penguin has moved from Near Threatened to Endangered on the IUCN Red List, based on projections that its population will halve by the 2080s.

Satellite images indicate a loss of around 10 per cent of the population between 2009 and 2018 alone, equating to more than 20,000 adult penguins.

The primary driver is the early breakup and loss of sea ice, the IUCN says, which has reached record lows since 2016.

Emperor penguins require fast ice – sea ice that is “fastened” to the coastline, ocean floor or grounded icebergs – as habitat for their chicks and during their moulting season, when they are not waterproof.

If the ice breaks up too early, the result can be deadly.

It is challenging to convert observed tragedies – such as the collapse of a breeding colony into the sea before the chicks can swim – into population changes.

But population modelling considering a wide range of future climate scenarios shows that without abrupt and dramatic reductions in greenhouse gas emissions, emperor penguin populations will rapidly decline during this century.

Penguins are already among the most threatened birds on Earth,” says Martin Harper, CEO of BirdLife International, which coordinated the emperor penguin assessment as the authority for birds on the IUCN Red List.

“The emperor penguin’s move to Endangered is a stark warning: climate change is accelerating the extinction crisis before our eyes. Governments must act now to urgently decarbonise our economies.”

Rising ocean temperatures reduce food for Antarctic fur seals

The Antarctic fur seal has moved from Least Concern to Endangered on the IUCN Red List.

Its population has decreased by more than 50 per cent from an estimated 2,187,000 mature seals in 1999 to 944,000 in 2025.

IUCN says the ongoing decline is due to climate change, as rising ocean temperatures and shrinking sea ice are pushing krill to greater ocean depths in search of colder water, reducing the availability of food for seals.

Krill shortages at South Georgia have reduced the survival of pups in their first year dramatically, leading to an ageing breeding population.

Other threats, such as predation by killer whales and leopard seals and competition with recovering baleen whale populations targeting the same krill, are potentially also impacting this declining population.

Avian flu threatens elephant seals

The southern elephant seal has also been reclassified, moving from Least Concern to Vulnerable on the IUCN Red List following declines caused by Highly Pathogenic Avian Influenza (HPAI).

There has been a significant increase in the prevalence of avian flu around the world since 2020, and it has spread to mammals. The disease has affected four of the five major subpopulations, killing more than 90 per cent of newborn pups in some colonies and seriously impacting adult females, which spend more time on the beaches than males.

There is growing concern that disease-related mortalities of marine mammals will increase with global warming – particularly in polar regions, where animals have not had much previous exposure to pathogens.

Animals that live close together in colonies, such as southern elephant seals, are particularly hard-hit by diseases.

Bird flu spread could be impacted by where waterfowl like to live



Reduced movement in human-heavy landscapes may change how the virus travels


University of Georgia





The movement patterns of waterfowl, including ducks, swans and geese, may affect the spread of highly pathogenic avian influenza in bird populations, according to a new study from the University of Georgia.

Researchers found that birds travel much shorter distances in areas with human activity, likely because those landscapes have plenty of food, water and shelter.

When birds stay in one place, disease doesn’t spread as much. But it could also mean more intense hotspots of disease outbreaks in concentrated areas.

By understanding the movement patterns of waterfowl outside of typical migration periods, scientists could better predict where bird flu, or H5N1, might spread next.

“Birds are like us. They’re always responding to what’s around them, whether that’s food availability or disturbance from people or other animals,” said Claire Teitelbaum, assistant unit leader with the U.S. Geological Survey’s Georgia Cooperative Fish and Wildlife Research Unit, lead author of the study and an adjunct assistant professor in the Warnell School of Forestry and Natural Resources. “We can take the environment, predict how much we think birds are moving and then use that to predict where avian flu is going to go.”

Waterfowl stay put in areas with diverse habitats, human influence

The researchers analyzed 20 years of data containing movement information from more than 4,600 total waterfowl spanning 26 species in the Northern Hemisphere. The scientists tracked how far the waterfowl moved over time during breeding and winter seasons, when birds “commute” regularly between areas used for resting and eating.

The distance of these so-called commutes, which took place outside of their regular seasonal migrations, appeared to depend on the birds’ environment. Birds in uniform areas, such as vast expanses of grasslands or farmlands, traveled six times farther to acquire food or a safe location to rest compared to birds in more diverse landscapes.

The waterfowl in those more varied landscapes, which ranged from wetlands to urban green spaces, often didn’t need to travel more than a mile around their “home” to meet all or most of their daily needs.

“If we provide enough diverse attractive habitats, these animals may want to stick around,”  Teitelbaum said. “Like humans, if you live in a suburban neighborhood where it’s just single-family homes for miles and miles, you’re going to have to drive miles and miles out of that area to get to work or shop. If you live in an urban center, you have everything you need right there.”

Locations with a significant human population also played a role, as they were more likely to have protected green spaces with water sources or cover. Human activity could also mean literal blocks that prevent bird movement, such as roads or fences.

Birds in these regions traveled about one-third of the distance of birds residing in sparser areas.

Different seasons could play role in bird flu spread outside of seasonal migrations

While yearly migrations are a major factor in the spread of H5N1, the present study aimed to understand how flight during breeding and winter seasons may add to transmission.

The researchers found that during winter months, movements were over twice as far when compared to travel during the breeding season. Waterfowl often had to fly farther in their daily routines to secure food or places to sleep, potentially carrying the virus with them.

In addition to studying these daily movements, the researchers found the same patterns when studying birds’ weekly movement distances. That’s key, Teitelbaum explained, as one week is also the incubation period for the virus.

Breeding season could present its own challenges. During this time, birds were less likely to travel far distances, instead remaining close to their nests. Although that can limit wider spread, it also could increase the risk for localized hotspots of the virus.

“If we want to keep the flu from spreading, we might want to see what we can do to keep the birds in one place, but there’s that flipside. Outbreaks happen when birds are in high density, so we might have increased transmission locally,” she said. “That’s the underpinning: How can we link the distances that birds are moving to the distances that flu is moving?”

This study was published in Ecology Letters.

Bird flu risk to Danish cattle – new tool can warn farmers before infection spreads



Bird flu can infect both cows and humans. Researchers from the University of Copenhagen have developed a tool that can predict where and when the risk of infection is highest.




University of Copenhagen





Sudden drop in milk production, thickened milk, and cows under movment restrictions. Since 2024, American farmers have had bitter experiences with the feared bird flu (H5N1), which in several cases has been introduced to cattle – and then spread rapidly among cattle herds. In some instances, humans have been infected as well. The contagious virus is increasingly being transmitted from wild birds to mammals –such as cattle.

The outbreaks in the U.S. raise the question of whether Denmark is sufficiently prepared should the infection spread to Danish cattle.

But now there is good news for both authorities and concerned dairy producers. Researchers from the University of Copenhagen have developed a tool that can predict where and when the risk of infection is highest. The tool is based on infection data from the U.S. outbreaks and adapted to Danish context.

“We have combined detailed data on wild bird abundance with cattle density in the U.S. to calculate how easily the infection can be transmitted from wild birds to cattle,” says You Chang, a postdoc at the Department of Veterinary and Animal Sciences at the University of Copenhagen.

So far, bird flu has not been detected in Danish cattle. But the experiences from the U.S., where more than 1,000 herds across 19 states have been infected, show that there is good reason to be prepared. The recent detection of H5N1 antibodies in several Dutch dairy cows and earlier cases in British sheep, suggests that bird flu may already be spilling over to non-poultry livestock in Europe. The researchers behind the study believe it is likely only a matter of time before Danish cattle test positive for bird flu – and knowledge and preparedness are therefore needed.

“This is the first European study that uses outbreak data from the U.S. to assess the risk of transmission of bird flu from wild birds to cattle, and applies that data to a European context,” says Beate Conrady, professor at the Department of Veterinary and Animal Sciences.

Denmark Is Especially Vulnerable

Several of the outbreaks on American cattle farms are directly linked to wild birds. And because Denmark is located along key migratory bird routes, our small country is particularly exposed. With the new tool, researchers have combined wild bird abundance, movement, outbreak in the other EU countries with information on cattle density. This knowledge makes it possible to pinpoint where – and when during the year – the risk of infection is highest.

“This gives Danish cattle farmers the opportunity to be alert if they know they are in a high-risk area and it’s a time of year when the risk is elevated. Then they can keep a closer eye on whether their animals show symptoms. At the same time, the knowledge can help authorities consider targeted surveillance, such as testing milk for early detection” says You Chang.

Data from the study shows that in Denmark the risk of infection is highest from December to March, and farmers located along the country´s western coasts and on Lolland should be especially vigilant.

Preparedness Should Be Standard

The first confirmed case of infection in cattle was registered in 2024 in the U.S. state of Texas. And the virus doesn’t just spread among animals. In the U.S., 71 people have been infected with the disease, which has primarily manifested as eye infections. It is mainly employees in the poultry and dairy sectors who have been infected.

Although the infection has not yet been detected in Denmark, there is good reason to be prepared. The researchers emphasize that the study focuses on the risk of the virus being introduced from wild birds into cattle herds. Whether the virus would spread further between farms in Denmark remains uncertain and is still under investigation.

“Being ready for a potential launch in Denmark is essential. Preparedness should not be a luxury – it should be standard,” says Beate Conrady.
