Panic spreads faster than a virus.

El virus hantavirus no es nuevo. Lo nuevo es la velocidad con la que alguien lo convirtió en el apocalipsis

It has been circulating among us for decades. The Andes strain was identified in 1995 in Argentina. The WHO records between 10,000 and 100,000 human infections per year worldwide. There is scientific literature, protocols, and accumulated research.

And yet, when cases appeared on a cruise ship, thousands of people experienced it as if the virus had fallen from the sky last week. That's not a public health problem. It's a communication problem.

What circulated on social media this week was a masterclass in how to destroy the credibility of information in real time:

A video of Macron announcing school closures "due to hantavirus." The clip was real. The context was March 12, 2020, when he was speaking about COVID-19. No one clarified this before it reached half a million people.

Publications claiming that Pfizer already has an mRNA vaccine ready. Pfizer directly denied it. But the denial doesn't travel as fast as the rumor.

Entire threads comparing this to March 2020. No data. No strain differentiation. No mention that human-to-human transmission is extremely limited and sustained outbreaks are exceptional.

The Spanish Ministry of Health said something that authorities rarely say so clearly: the health risk to the general population is extremely low, but there is a real risk of misinformation on social media that can lead to alarmism.

They weren't worried about the virus. They were worried about the panic.

The pattern is always the same.

A real event occurs, with real deaths and people affected that deserve serious coverage. Before any specialist has been able to analyze the situation, someone with 400,000 followers has already posted a 60-second video recorded in their bathroom.

He didn't read the WHO report. He didn't consult an infectious disease specialist. He didn't differentiate between strains. He read the headline, felt a sense of urgency, and hit publish.

That's not informing. That's spreading panic with good lighting.

The doctor who actually knows what he's talking about, meanwhile, is writing a 1,400-word thread that will be read by 3,000 people.

There's something we communicators have to accept, even if it's not easy: the problem isn't just the algorithm or the platform. The problem is also that we've learned to measure success by reach, and reach rewards emotional intensity, not precision.

Communicating health requires the opposite of what the digital ecosystem rewards: slowness, nuance, historical context, and honesty about uncertainty. All of which reduces engagement.

So we have an information market where the irresponsible communicator, unintentionally, has a structural advantage over the rigorous one. That's what needs to be named.

Three people died on that cruise ship. That's a fact and deserves to be taken seriously.

What they don't deserve is for their deaths to become raw material for panic content.

The next time a health event breaks the news cycle, the most useful question any communicator can ask themselves, whether they have 200 followers or two million, is just one:

Do I really understand what I'm about to explain?

The virus isn't transmitted through screens. Panic is.
