Eight hundred people.
In one country.
Dead from measles.
In 2026.
Sí, es una cifra terrible.
Yes, it's a terrible number.
El brote de sarampión en Bangladesh ya tiene más de ochocientas muertes, y muchas de las víctimas son niños pequeños.
The measles outbreak in Bangladesh has now passed eight hundred deaths, and many of the victims are young children.
And what makes it so hard to sit with is that there's a vaccine.
A cheap, effective, well-understood vaccine that has existed for over sixty years.
Exacto.
Exactly.
La vacuna contra el sarampión existe desde los años sesenta y es muy efectiva.
The measles vaccine has existed since the 1960s and it's very effective.
El problema en Bangladesh no es la ciencia, es el sistema.
The problem in Bangladesh isn't the science, it's the system.
Walk me through what happened.
Where did this start, and why did it get this bad this fast?
El brote empezó a principios de este año.
The outbreak began earlier this year.
Las autoridades dicen que muchos niños no recibieron la vacuna en los últimos años, especialmente durante y después de la pandemia de COVID.
Authorities say many children didn't receive the vaccine in recent years, especially during and after the COVID pandemic.
Right, the COVID disruption to routine vaccination.
That thread keeps showing up in every outbreak story I've read in the last two years.
Es un problema muy serio.
It's a very serious problem.
Cuando los sistemas de salud están ocupados con una emergencia grande, los programas normales de vacunación sufren.
When health systems are busy with a major emergency, normal vaccination programs suffer.
Y los efectos se ven después, cuando los niños sin vacuna son ya muchos.
And the effects show up later, when there are many unvaccinated children.
There's a term epidemiologists use for this: immunity debt.
The idea being that when you interrupt vaccination for a few years, you're not just missing one cohort of kids, you're building up a pool of susceptible people that an outbreak can tear through.
Sí, es exactamente eso.
Yes, that's exactly it.
Y el sarampión es especialmente peligroso porque se contagia muy fácilmente.
And measles is especially dangerous because it spreads very easily.
Es uno de los virus más contagiosos que existen.
It's one of the most contagious viruses that exist.
The R-naught on measles, the base reproduction number, is somewhere between twelve and eighteen.
To put that in context, seasonal flu is around one point three.
COVID at its most contagious variants was maybe eight or nine.
Claro.
Right.
Si una persona con sarampión entra en una habitación, casi todos los que no están vacunados se infectan.
If one person with measles enters a room, almost everyone who isn't vaccinated gets infected.
Por eso necesitas vacunar a casi toda la población para detener el virus.
That's why you need to vaccinate almost the entire population to stop the virus.
Ninety-five percent coverage to reach herd immunity.
That's the number.
And Bangladesh has been falling short of that for years now.
Sí, y no es solo Bangladesh.
Yes, and it's not just Bangladesh.
En muchos países la cobertura de vacunación bajó mucho en los años de la pandemia.
In many countries vaccination coverage dropped a lot during the pandemic years.
Pero Bangladesh tiene también otros problemas: zonas rurales muy remotas, mucha pobreza, y un sistema de salud con pocos recursos.
But Bangladesh also has other problems: very remote rural areas, a lot of poverty, and a health system with limited resources.
I spent time in Dhaka back in the early 2000s, covering the aftermath of a cyclone.
The last mile problem in healthcare delivery there is genuinely brutal.
Getting anything, medicines, clean water, vaccines, out to rural char islands during monsoon season is a logistical nightmare.
Y las inundaciones del año pasado en Bangladesh afectaron mucho a las campañas de vacunación.
And last year's floods in Bangladesh badly affected vaccination campaigns.
Cuando las familias tienen que moverse porque el agua sube, perder una cita médica es lo normal.
When families have to move because the water rises, missing a medical appointment is completely normal.
Climate and public health intersecting in the worst possible way.
You displace people, you lose track of who's been vaccinated, you lose cold chain for the vaccines themselves.
Everything breaks at once.
Exacto.
Exactly.
Las vacunas necesitan frío para funcionar.
Vaccines need cold to work.
Si no tienes electricidad en una zona inundada, las vacunas no sirven.
If you don't have electricity in a flooded area, the vaccines are useless.
Es un problema técnico muy importante.
It's a very important technical problem.
Now, I want to push back slightly on one framing I've seen in some of the coverage, which is the vaccine hesitancy angle.
Is that actually a significant factor here, or is this primarily an access and infrastructure story?
Es principalmente un problema de acceso, no de rechazo a las vacunas.
It's primarily an access problem, not vaccine rejection.
La mayoría de las familias en Bangladesh quieren vacunar a sus hijos, pero no siempre pueden llegar a los centros de salud, o los centros no tienen las vacunas.
Most families in Bangladesh want to vaccinate their children, but they can't always get to health centers, or the centers don't have the vaccines.
That distinction matters enormously for how you respond to an outbreak.
The interventions are completely different if the problem is distrust versus if the problem is roads, supply chains, and clinic hours.
Sí.
Yes.
Y en Bangladesh el gobierno sabe que tiene que llegar a las familias, no esperar que las familias vengan al sistema.
And in Bangladesh the government knows it has to reach families, not wait for families to come to the system.
Las campañas de vacunación tienen que ir a las casas, a las escuelas, a los mercados.
Vaccination campaigns have to go to homes, to schools, to markets.
Let's zoom out historically for a second, because I think this story lands differently when you remember what measles used to be.
Before the vaccine, this wasn't a rare tragedy.
This was just childhood.
Antes de la vacuna, el sarampión mataba a más de dos millones de personas al año en todo el mundo.
Before the vaccine, measles killed more than two million people a year worldwide.
Era una de las enfermedades más mortales para los niños.
It was one of the deadliest diseases for children.
La vacuna cambió todo eso.
The vaccine changed all of that.
And by 2000, the WHO was genuinely talking about elimination as a realistic goal for many regions.
Not just control, elimination.
Measles was supposed to join the short list of diseases we've beaten.
Y en muchos países lo consiguieron.
And in many countries they achieved it.
En América, por ejemplo, el sarampión fue eliminado en 2016.
In the Americas, for example, measles was eliminated in 2016.
Pero después los casos volvieron porque la cobertura de vacunación bajó en algunos lugares.
But then cases returned because vaccination coverage dropped in some places.
The Americas elimination was a genuine public health triumph.
And it held for years.
Then came the anti-vaccination movements, then came COVID, and the numbers started climbing back.
The Americas actually lost that elimination status.
Es muy frustrante.
It's very frustrating.
Trabajas durante décadas para eliminar una enfermedad y después de unos pocos años sin buena cobertura, el virus vuelve.
You work for decades to eliminate a disease and then after a few years of poor coverage, the virus comes back.
El sarampión no desaparece solo, necesita que los humanos lo eliminen activamente.
Measles doesn't disappear on its own, it needs humans to actively eliminate it.
What's the response been from international bodies?
UNICEF, WHO, that whole architecture of global health.
La OMS y UNICEF están trabajando con el gobierno de Bangladesh, pero los expertos dicen que la respuesta fue lenta al principio.
The WHO and UNICEF are working with the Bangladesh government, but experts say the response was slow at first.
Cuando el número de muertos ya es muy alto, es difícil controlar el brote rápidamente.
When the death toll is already very high, it's difficult to control the outbreak quickly.
There's a predictable pattern to these things, isn't there.
The early cases get attributed to other causes.
The surveillance system misses the signal.
By the time it's confirmed and response is mobilized, you've already lost weeks.
Sí, y Bangladesh también tuvo problemas políticos este año, con cambios en el gobierno.
Yes, and Bangladesh also had political problems this year, with changes in government.
Cuando hay inestabilidad política, los programas de salud pública sufren porque no hay una dirección clara.
When there's political instability, public health programs suffer because there's no clear leadership.
The broader implication here, beyond Bangladesh, is what this says about where we are globally with vaccine-preventable diseases.
Because the trend line is not going in the right direction.
Es verdad.
It's true.
Los casos de sarampión en el mundo subieron mucho en 2023 y 2024, y en 2025 continuaron subiendo.
Measles cases worldwide rose a lot in 2023 and 2024, and in 2025 they continued rising.
Bangladesh es el caso más grave ahora, pero no es el único país con problemas.
Bangladesh is the most severe case right now, but it's not the only country with problems.
And the thing I keep coming back to, the thing that feels almost unbearable about this story, is the cost of the solution.
Two doses of the MMR vaccine.
A few dollars per child.
We're not talking about some cutting-edge pharmaceutical that only rich countries can afford.
La vacuna cuesta menos de un euro por dosis.
The vaccine costs less than a euro per dose.
El problema no es el precio.
The problem isn't the price.
El problema es llegar a cada niño, tener el personal, tener los vehículos, tener la cadena de frío.
The problem is reaching every child, having the staff, having the vehicles, having the cold chain.
Todo eso cuesta dinero y necesita organización.
All of that costs money and needs organization.
The infrastructure problem.
Which is ultimately a political problem, a funding problem, a governance problem.
The science solved measles sixty years ago.
Everything since then has been a political and logistical failure.
Sí, y eso es lo más difícil de explicar a la gente.
Yes, and that's the hardest thing to explain to people.
No necesitamos una nueva vacuna.
We don't need a new vaccine.
No necesitamos una nueva tecnología.
We don't need a new technology.
Solo necesitamos voluntad política y recursos para hacer bien lo que ya sabemos hacer.
We just need political will and resources to do well what we already know how to do.
You used a phrase earlier that I want to ask you about, because it stuck with me.
You said the response was not clear, and I keep thinking about the way Spanish uses "debería" in contexts like this.
"Esto no debería pasar." There's something in that construction.
Sí, "debería" es muy útil para hablar de situaciones que son incorrectas o injustas.
Yes, 'debería' is very useful for talking about situations that are wrong or unjust.
"Esto no debería pasar" significa "this should not happen." Es el condicional del verbo deber.
'Esto no debería pasar' means 'this should not happen.' It's the conditional form of the verb deber.
So it's not just a wish, it carries a sense of moral weight.
Like something that ought to be true but isn't.
"Los niños no deberían morir de sarampión." Kids shouldn't be dying of measles.
That lands differently than just saying it doesn't happen.
Exacto.
Exactly.
"Debería" expresa obligación moral o una expectativa que no se cumple.
'Debería' expresses moral obligation or an expectation that isn't met.
Puedes decir "debería llover mañana" para una predicción, pero también "esto no debería ser tan difícil" cuando algo es injusto.
You can say 'debería llover mañana' for a prediction, but also 'esto no debería ser tan difícil' when something is unjust.
Es una palabra muy expresiva.
It's a very expressive word.
I'll hold on to that one.
"Esto no debería pasar." Feels like the sentence this whole episode has been building toward, honestly.
Sí, y es una frase que, desgraciadamente, necesitamos usar mucho cuando hablamos de salud global.
Yes, and it's a phrase that, unfortunately, we need to use a lot when we talk about global health.
Ochocientas muertes de sarampión en 2026.
Eight hundred measles deaths in 2026.
Esto no debería pasar.
This should not be happening.
