Science needs time. Television needs answers now.
During a hantavirus outbreak traced to a cruise ship, a Seville immunologist gave 82 interviews across 12 days—drawing infographics in his kitchen, skipping meals, sleeping three hours a night—almost entirely without pay. His marathon of public service illuminates an old tension made newly urgent: science moves on evidence and caution, while crisis demands instant clarity. The episode raises a question that outlasts any single outbreak—not merely how scientists should communicate, but whether society has quietly decided that the labor of public trust belongs to whoever is willing to sacrifice themselves for it.
- A hantavirus outbreak aboard a cruise ship turned an obscure pathogen into a national conversation overnight, placing one immunologist at the center of an unrelenting media storm.
- Eighty-two interviews in twelve days meant stolen sleep, skipped meals, and a phone answered mid-lecture—while only a single outlet offered any payment.
- Simple words kept failing: the word 'intimate' confused presenters, so the scientist drew transmission diagrams in his kitchen that reached millions and became the visual shorthand for public understanding of the risk.
- Misinformation—some of it voiced from positions of authority—spread faster than the virus, forcing the scientist to debunk claims about insects and swimming rodents on national television while racing back to teach his students.
- The crisis is landing not just as a public health story but as an institutional one: the system that delivers expert knowledge to the public runs almost entirely on unpaid vocation, and that arrangement is beginning to show its cost.
An immunologist in Seville spent twelve days at the center of a national hantavirus scare, giving 82 interviews, drawing more than twenty infographics, sleeping as little as three hours some nights, and skipping meals—all while continuing to teach. Only one outlet paid him. He didn't ask the others for money, and they didn't offer it. He understood he was doing something larger than himself. But the experience left him with a question that wouldn't leave: what does society now expect from scientists, and at what cost?
The outbreak, linked to the cruise ship MV Hondius, transformed hantavirus from a medical footnote into front-page noise. He fielded calls from Spain's major television and radio networks, asked his students' permission to answer the phone during lectures, and appeared on The Wild Project—a podcast some academics might dismiss—where a single episode accumulated over 800,000 views in eleven days, a reach that conventional television could no longer guarantee.
By the second or third day, he understood that words alone weren't enough. Every interview hit the same wall: he would explain that hantavirus required intimate contact to spread, and he would watch the presenter's face cloud with confusion. So he drew it—a diagram created one evening in his kitchen, listing six specific transmission scenarios aboard a ship, closing with the line: 'It is not passing someone in a hallway.' By the next morning, the image was on three television screens. Within a week, it had become the visual reference most Spaniards used to understand the actual risk.
The deeper tension was structural. Science demands data, peer review, and time. Television demands immediate clarity. Radio needs comprehensible phrases. Social media demands synthesis. And citizens need answers that biology, public health law, international logistics, and hospital capacity rarely make simple. When some journalists tried to steer him toward the answer they wanted, he found himself on terrain that was not his own.
Fear and misinformation, he observed, transmit faster than any virus. Some of the most damaging claims—that hantavirus spread through insects, that a moored ship threatened the general population—came not from anonymous citizens but from spaces of public responsibility. He warned on national television that rumors could spill into politics and amplify alarm unnecessarily. He had to leave the studio early to make it back to class. The host turned his departure into a small tribute to teaching. From media panic to the daily obligation of continuing to educate.
He does not regret the 82 interviews. What troubles him is that society has quietly normalized this extreme availability—this willingness of scientists to be everywhere at once—as something that rests entirely on voluntarism and personal sacrifice. The public needs experts who are present. But it also needs to care for the people who sustain that conversation.
An immunologist in Seville spent twelve days answering the same questions about a hantavirus outbreak aboard the cruise ship MV Hondius. Eighty-two times. He drew more than twenty infographics. He skipped meals. He slept three hours on some nights. Only one interview paid him. He didn't ask for money from the others, and they didn't offer it. He understood, in the moment, that he was doing something larger than himself—a public service, he thought. But the experience left him with a question that won't leave: What has changed in what society expects from scientists, and at what cost?
The hantavirus had been an obscure word, something you might encounter in a medical textbook or in discussions of remote regions. Then it became everywhere—in headlines, in family conversations, in the chatter of social media. The immunologist found himself at the center of that noise, fielding calls from RTVE, Telecinco, Antena 3, the major Spanish radio networks. He asked his students for permission to answer the phone during lectures. They didn't mind. But when he appeared on The Wild Project, a podcast hosted by Jordi Wild that many academics might dismiss as secondary, his students erupted in genuine excitement. He realized then that he, too, was aging out of the cultural moment. That single podcast episode accumulated more than 800,000 views in eleven days—a reach that conventional television could no longer guarantee.
By the second or third day, he understood that words alone would not work. Every interview followed the same pattern: the journalist would ask if hantavirus was contagious, he would say yes but with important caveats, he would mention that it required intimate contact, and he would watch the presenter's face cloud with confusion about what "intimate" actually meant in a public health context. So he drew it. One evening in his Seville kitchen, using design software and a pair of generative AI tools, he created a simple diagram showing six specific situations where the Andes virus could spread on a cruise ship: sharing a cabin, sharing a bed, intimate or very close contact, caring for a sick person without protection, handling contaminated clothing or bodily fluids, or providing medical care without proper equipment. The closing line wrote itself: "It is not passing someone in a hallway or briefly sharing a space." By the next morning, that image was on three television sets. Within a week, it had become the visual reference point that most Spaniards associated with their understanding of the actual risk.
The real tension, though, lay deeper. Science requires data, contrast, peer review, caution, and time. Television requires immediate clarity. Radio needs comprehensible phrases. Social media demands synthesis. Digital outlets need headlines. And citizens need answers. But in a health crisis, the answers are rarely simple or complete. Why does one country demand a confirmatory PCR test while another accepts an initial result? Why are some quarantines mandatory and others merely recommended? What is day zero of an exposure? What do you do with people who had contact with a case before anyone knew it was a case? These questions combine biology, public health law, international logistics, hospital capacity, laboratory standards, diplomacy, and public perception of risk. When some journalists—fortunately a minority—tried to manipulate him into giving the answer they wanted, the scientist found himself on terrain that was not his own.
There is a biological chain of transmission in any zoonotic disease, but there is also an emotional one. Fear transmits. Suspicion transmits. Misinformation transmits. Political anger transmits. And often faster than the virus itself. During those twelve days, he had to debunk absurd claims—that hantavirus could spread through insects, that a moored ship posed a risk to the general population because of swimming rodents. Some of these claims did not originate from anonymous citizens but from spaces of public responsibility. When misinformation wears the mask of authority, the damage multiplies. He made a point of this on Spanish television, warning that rumors could spill into politics and unnecessarily amplify public alarm. The moment had an unintended grace: he had to leave the studio early because he was late for class. The host, Silvia Intxaurrondo, turned it into a small tribute to teaching and scientific communication. From the television studio to the classroom, from media panic to the daily obligation of continuing to educate.
He spoke to outlets across the ideological spectrum deliberately. In a health crisis, a scientist cannot communicate only in friendly spaces; you must speak where citizens actually are. He felt generally welcomed, sought after, respected. There were uncomfortable moments too. Some interviewers treated him with inappropriate manners. Some producers kept guests on video standby far too long before their segment, not understanding that those stolen minutes meant less sleep, less time to study, less time to eat or use a bathroom. What struck him most was the discovery that a good image could explain in seconds what an interview takes several minutes to convey. The visual communication he created was not decoration. It was a precision tool. Done well, it does not simplify science—it makes it accessible. And in a crisis, accessibility is not a luxury. It is a public health intervention.
He does not regret the eighty-two interviews. He made them because he believed they needed to be made. What troubles him is that society has normalized this extreme availability of scientists, this willingness to be everywhere at once, as something that rests entirely on voluntarism, vocation, and personal sacrifice. The public needs experts who are available. But it also needs to care for the people who sustain that conversation.

The Hearth Conversation Another angle on the story
You gave eighty-two interviews in twelve days. That's nearly seven a day. How did you physically manage that?
I didn't, really. I skipped meals. I slept three hours some nights. But the strange part is that you don't feel the exhaustion in the moment because the demand is constant—the phone keeps ringing, and you answer it.
Why did you answer it? You could have said no.
Because in that moment, I genuinely believed it was necessary. A virus was spreading, people were frightened, and I had information that could help them understand the actual risk. That felt like an obligation.
But only one interview paid you.
Yes. And I didn't ask for payment, and they didn't offer it. That wasn't about the money—it was about the principle. We've accepted that scientists should be available on demand, for free, whenever there's a crisis. We've normalized that.
The infographics seem to have been the real breakthrough. Why did those work when the interviews didn't?
Because they removed ambiguity. When I said "intimate contact," people imagined different things. When I drew exactly which situations posed risk and which didn't, there was nowhere for confusion to hide. In a crisis, that clarity is everything.
Do you think you'll do this again if another outbreak happens?
I hope I won't have to. Not because I wouldn't want to help, but because I think we need to ask ourselves whether we can keep asking scientists to do this work on this basis. The public needs experts available. But we also need to protect the people who make that possible.
