Hantavirus is the new big bad haunting the news cycle and social media feeds of everyone.
The news of three passengers on a Dutch cruise ship dying of a rare strain of hantavirus, known as the Andes strain, was like wildfire, causing a lot of panic and fear among the general public.
The reason for this can be summarised in one word: COVID-19.
The pandemic that took over the world for a good half-decade has still not left the psyche of people, and clearly, a new virus seeing an outbreak was enough to activate the PTSD of many people who are still recovering from the stress of the coronavirus.
Adding to the panic, came a 2022 post from an account called @iamasoothsayer, that said: “2023: Corona ended. 2026: Hantavirus.”
The account’s bio simply read “reads the future, ” and the post was even fact-checked by Lead Stories, using the Internet Archive’s Wayback Machine, that the post was published in 2022 and has never been edited.
The collective nervous system of a world that spent years under COVID lockdowns did not take the news calmly. Reddit threads erupted. “I can’t do this again,” users wrote, in earnest.
However, with the memes and funny videos being made around this, there has also been a lot of misinformation about the hantavirus that is spreading, leading to even more panic and fear.
Health influencers have been posting infographics on Instagram and TikTok, but while some information they’re relaying might be accurate, a lot of it is not.
By the first week of May 2026, “hantavirus” was one of the most searched terms globally, and the familiar machinery of pandemic anxiety had kicked into gear: the breathless headlines, the conflicting advice, the screenshots sent with the caption, “Is this real??”
So here, we take a look at what this disease is, whether it is dangerous, and whether it could reach us here in India.
What Is Hantavirus? And What Exactly Happened?
The hantavirus, as a word, reached mainstream consciousness when MV Hondius, a Dutch-flagged luxury expedition cruise ship, reported having lost three passengers to this disease.
On 1 April 2026, it departed from Ushuaia, Argentina, one of the southernmost cities in the world, carrying roughly 150 passengers and crew from 23 different nationalities.
However, soon, reports came out about the death of three passengers on board. This included an elderly Dutch man (who died on board on April 11), his 69-year-old wife (who died in a Johannesburg clinic on April 26), and a German woman (who died on board on May 2).
The World Health Organisation (WHO) was notified, and they later on confirmed that the cause of these deaths was the Andes strain of hantavirus.
Now, the WHO has explained that the hantavirus, which is not a single disease but a family of rodent-borne viruses, infects humans primarily through contact with the urine, faeces, or saliva of infected rodents, or by touching contaminated surfaces.
There are myths that the strain is mostly found in rural settings; however, that is not true. It can be present in any place where rodents are plentiful, and the opportunities for exposure are greater.
According to reports, it is the only strain that can be transmitted between humans. This, though, seems to have been translated to mean that it can spread through casual human contact. Which is not true. Since it is a rodent-borne disease, it only spreads when people breathe in contaminated air that is infected due to rodent droppings, urine, or saliva.
Dr Balram Bhargav, former DG, ICMR, speaking with Firspost, explained that the animals don’t get sick from the virus themselves, saying, “They shed it in their urine, droppings, and saliva. The infection spreads if humans come in contact with them during cleaning, farming, or simply entering an infested space.”
Dr K Srinath Reddy, eminent public health expert and chancellor, PHFI University of Public Health Sciences, further explained that, “In most cases, the spread has been seen from animal to man. The droppings generally dry, become aerosolised, and can be inhaled by a nearby human. The virus can also infect humans if they eat contaminated food or touch a contaminated object and then touch their mouth.”
Dr Bhargava, along with various other medical professionals, is currently saying that it is not like COVID and doesn’t spread in the same manner.
He said, “Unlike COVID, hantavirus doesn’t typically spread from person to person very easily. COVID-19 is a highly contagious respiratory virus that spreads easily from person to person. In this case, transmission requires very close contact, and is mostly from droplets.”
Dr Aravinda SN, lead consultant, internal medicine, Aster RV Hospital, Bengaluru, speaking with Hindustan Times, also added, “Humans contract the virus through direct contact with infected rodents, which carry the virus in their urine, saliva, and droppings.”
He also said, “Individuals contract the infection because they breathe in particles which contain the virus that become airborne during the process of cleaning spaces which lack proper ventilation.”
Along with how “Human-to-human transmission is extremely uncommon. Most hantavirus strains reported in North America and several other regions cannot spread between individuals according to existing research.”
The spread of the Andes virus from person-to-person is mostly from prolonged close contact with someone infected, including exposure to the infected person’s saliva, respiratory secretions, or other body fluids, such as kissing, sharing utensils, or handling contaminated bedding.
Sabra Klein, a professor in the molecular microbiology and immunology department at the Johns Hopkins Bloomberg School of Public Health, speaking with NBC News, said, “Andes virus, as a hantavirus, requires a significant degree of contact with bodily fluids. In the original reports that came out in the early 2000s, case studies show spread between married couples, people who live together, and are intimate. That is where you have the spread.”

According to WHO Director-General Dr Tedros Adhanom Ghebreyesus, the couple is speculated to have caught the strain off the ship, since they “travelled through Argentina, Chile and Uruguay on a birdwatching trip which included visits to sites where the species of rat known to carry the virus was present.”
The close quarters of a ship, with 150 people living, sharing air and space on a ship with no way to run a proper diagnostic, made the situation uniquely dangerous.
According to a Harvard Health Publishing report, reviewed by Robert H. Shmerling, MD, Senior Faculty Editor, the symptoms of hantavirus include “fatigue, fever, and muscle aches, especially in the large muscle groups – thighs, hips, back, and sometimes shoulders.”
Some of the infected people also experienced “headaches, dizziness, chills, and abdominal problems such as nausea, vomiting, diarrhoea, and abdominal pain. Four to 10 days later, other symptoms may appear, including coughing and shortness of breath, as the lungs fill with fluid.”
The incubation period, meaning the amount of time it takes from a person getting infected to showing symptoms, is said to be anywhere between two to three weeks and eight weeks.
Is It Dangerous? And How Long Have Experts Known?
If you want the answer to the first question in one word, then yes, simply put, hantavirus is genuinely dangerous. However, it is also important to understand that while the case fatality rate is less than 1–15% in Asia and Europe and up to 50% in the Americas, early supportive care and immediate referral to a facility with a complete ICU can improve survival.
The upper end of these estimates is also said to be from data that is almost 30 years old, as per the UK Health Security Agency, and the rate might have declined by now.
So even though there is no vaccine or antiviral treatment as of now, early detection and preventative measures being taken to maintain a clean and hygienic environment, removal of rodents, cleaning with proper equipment, including gloves and a mask, can help a lot.
The virus family takes its name from the Hantan River in South Korea. During the Korean War between 1951 and 1954, around 3,200 United Nations soldiers stationed near the river developed a mysterious haemorrhagic fever.
At the height of the epidemic, more than 10 percent of those infected died. Army doctors named the illness ‘Korean haemorrhagic fever.’ They could describe its symptoms in detail, but could not identify the cause.
It remained unknown for a long time, however, as per the National Archives of Korea, in 1976, South Korean virologist Ho Wang Lee successfully isolated the virus from the lungs of a field mouse. Lee even developed the world’s first preventive vaccine against the disease, Hantavax, in 1988.
Western science, though, took almost till 1993 to really pay attention to the virus, when the American Southwest was struck by a new version of the virus.
Dr Michelle Harkins, Division Chief of Pulmonary, Critical Care and Sleep Medicine at UNM Hospital, described what happened: “It was in the spring of 1993, there were several very young, healthy individuals from the Navajo Nation along the border of Arizona and New Mexico in Huerta Canyon that contracted a very mysterious, rapidly fatal disease.”
Since then, hantavirus has continued to make sporadic appearances across the world at different times.
The reason it has not been discussed that much in mainstream avenues is that it was localised, it was rare, it killed people, but did not spread easily between people.
Amesh Adalja, a senior scholar at the Johns Hopkins Center for Health Security, told Newsweek, “Pandemic potential is mostly about transmission architecture, not lethality. The biology that drives pandemics is how a pathogen moves between people — not how sick it makes them.”
Maria Van Kerkhove, director of epidemic and pandemic management at the World Health Organisation (WHO), during a briefing also said, “This is not Covid, this is not influenza. It spreads very, very differently,” adding, “This is not the same situation we were in six years ago … It’s very different.”
Can Hantavirus Reach India?
This is the question that matters most for us Indians, and the answer, from most credible sources, seems to be the same: the immediate risk is very low, but it warrants awareness rather than indifference.
Two Indian crew members were confirmed to be aboard the MV Hondius at the time of the outbreak. Both were confirmed asymptomatic and under observation as per international health protocols, according to India’s Union Health Ministry.
But their presence on the ship, and the virus’s incubation window of up to eight weeks, prompted a national conversation about preparedness.
Dr Naveen Kumar, Director of the ICMR-National Institute of Virology (NIV) in Pune, stated clearly: “At present, the reported infections among Indian nationals aboard a cruise ship appear to be isolated imported cases and do not indicate community spread in India. Since hantavirus transmission is primarily rodent-borne and not easily spread between humans, the immediate public health risk remains low.”
Dr Kumar was also quoted by PTI saying that, “India has diagnostic capacity for hantavirus infection through the ICMR-National Institute of Virology and the nationwide Viral Research and Diagnostic Laboratory Network of 165 labs, where RT-PCR facilities are available for confirmation of suspected cases.”
An NDTV report quoted Dr. Pradeep Narayan Sahu, Consultant – Internal Medicine, Manipal Hospital Bhubaneshwar, saying, “For India, the overall risk remains low because there have been no major hantavirus outbreaks reported in the country so far. However, experts warn that poor sanitation, rodent infestations, flooding, and overcrowded living conditions can increase the chances of exposure, especially during monsoon months and in rural or poorly ventilated spaces.”
Dr. Neha Rastogi, Senior Consultant, Infectious Disease, Fortis Memorial Research Institute, Gurugram, also added, “At present, the risk for the general public in India remains very low. Awareness and hygiene are the best protection.”
This means that even if the risk of the virus reaching India, or COVID levels, is low, that doesn’t mean we should be ignorant of it.
Dr Aravinda advises that “People should avoid contact with rodents and maintain proper hygiene to protect themselves from potential infections.” He also warns that “One should avoid using dry sweeping or vacuuming methods to clean rodent waste because these methods will spread infectious materials into the surrounding air.”
Instead, “People should use gloves, masks, and disinfectants when they perform cleaning work in contaminated areas,” he said.
Dr. Reddy also explains that, “One lesson that keeps coming back is that crowded, enclosed spaces can become super-spreader settings. We have to ensure cleanliness and sanitation in cities, rodent infestation needs to be checked, and precaution and surveillance are the key.”
Doctors have also advised people to:
- Keep homes and surroundings rodent-free
- Store food in sealed containers
- Avoid sweeping dry rodent droppings directly
- Use disinfectant and gloves while cleaning
- Ventilate closed rooms before entering
- Maintain hygiene in homes and workplaces
Right now, the hardest and most difficult thing to do is not to panic.
Listen to actual medical professionals, keep your surroundings clean, and take preventive measures like masking and using gloves at most.
Keep a lookout for official notices by the government or medical bodies, and then actually follow any rules they might have laid down.
It might be easier said than done, but do not buy into sensationalised posts and videos, or ones that seem to validate your fears.
