Transcript

Fletcher EN

There was a flight last week.

Paris to Detroit, Air France, completely routine.

Except it didn't land in Detroit.

It landed in Montreal, because somewhere on that plane was a passenger from the Democratic Republic of Congo.

Octavio ES

Sí.

Yes.

El pasajero no está enfermo.

The passenger is not sick.

Pero es del Congo.

But he is from Congo.

Fletcher EN

Right, and that, I think, is where this story gets complicated fast.

The person wasn't showing symptoms.

They just came from a country with an active Ebola outbreak.

And that was enough to redirect a whole plane.

Octavio ES

El ébola es muy peligroso.

Ebola is very dangerous.

La gente tiene miedo.

People are afraid.

Es normal.

That is normal.

Fletcher EN

Sure, the fear is understandable.

But here's what landed in the same news cycle: the WHO put out a report saying this outbreak probably started two months ago, triggered by a single superspreading event, and it went completely undetected for weeks.

Nobody knew.

Octavio ES

Dos meses sin saber.

Two months without knowing.

Eso es muy malo.

That is very bad.

Fletcher EN

Two months.

And the word the WHO used was 'superspreading event,' which in epidemiology means one infected person passed it to an unusually large number of others, probably at a single gathering.

A funeral, a market, a hospital ward.

We don't know yet.

Octavio ES

En el Congo, los funerales son muy importantes.

In Congo, funerals are very important.

La familia toca al muerto.

The family touches the dead.

Esto es peligroso con el ébola.

This is dangerous with Ebola.

Fletcher EN

That's a really important point.

Ebola spreads through contact with body fluids, and traditional burial practices in parts of Central and West Africa involve washing and touching the body.

Mourning rituals that are deeply meaningful become vectors of transmission, and that tension has been at the center of every major Ebola response since the 1970s.

Octavio ES

El primer caso de ébola fue en 1976.

The first Ebola case was in 1976.

También en el Congo.

Also in Congo.

El río Ébola está allí.

The Ebola River is there.

Fletcher EN

The virus was literally named after a river in what is now the DRC.

And here we are, fifty years later, still dealing with outbreaks in the same region.

That's not a coincidence, that's a structural problem.

Octavio ES

El este del Congo tiene muchos problemas.

Eastern Congo has many problems.

Hay guerra.

There is war.

Hay pobreza.

There is poverty.

Los hospitales son muy pequeños.

The hospitals are very small.

Fletcher EN

Eastern Congo has been in a state of near-continuous armed conflict for thirty years.

You can't build a functioning public health system in a war zone.

Contact tracers can't follow chains of transmission when armed groups are moving through the same territory.

It's epidemiology in an impossible environment.

Octavio ES

Y el mundo solo mira cuando el virus llega a Europa o a América.

And the world only watches when the virus arrives in Europe or America.

Fletcher EN

That is an uncomfortable truth, and I've seen it firsthand.

I was in West Africa during the tail end of the 2014 outbreak, and the international response didn't really scale up until cases showed up in Dallas and Madrid.

Before that, it was, frankly, a second-tier story in most Western newsrooms including some I worked for.

Octavio ES

En 2014, muchas personas mueren.

In 2014, many people die.

Más de once mil personas.

More than eleven thousand people.

Fletcher EN

Eleven thousand dead in that outbreak, the vast majority in Guinea, Liberia, and Sierra Leone.

And the international community's response, when it finally came, actually worked.

Vaccines were developed, deployed.

So now we have tools we didn't have in 1976.

The question is whether those tools can reach the right places in time.

Octavio ES

Hay una vacuna para el ébola ahora.

There is a vaccine for Ebola now.

Pero es difícil llevarla al este del Congo.

But it is difficult to get it to eastern Congo.

Fletcher EN

The vaccine exists, the supply chains are the problem.

And this is where two months of undetected spread really hurts, because ring vaccination, the strategy they use, relies on identifying contacts of confirmed cases and vaccinating them fast.

If two months passed before anyone knew, the rings are enormous.

Octavio ES

¿Y el avión?

And the plane?

Hablamos de ese pasajero del Congo.

We talk about that passenger from Congo.

Fletcher EN

Yes, let's come back to that, because I find it genuinely troubling.

A person, apparently healthy, gets on a flight in Paris.

The U.S.

diverts the plane to Canada because of where that person is from.

Not because of symptoms.

Not because of confirmed exposure.

Just, origin country.

Octavio ES

Entiendo el miedo.

I understand the fear.

Pero esa persona no está enferma.

But that person is not sick.

Eso no es justo.

That is not fair.

Fletcher EN

There's a long and not particularly proud history here.

During the 2014 outbreak, several states in the U.S.

imposed mandatory quarantines on returning healthcare workers, including a nurse named Kaci Hickox who'd just spent weeks treating Ebola patients in Sierra Leone, came home, tested negative, and was put in a tent outside a hospital in New Jersey.

She sued.

She won.

Octavio ES

La gente tiene miedo.

People are afraid.

El miedo no escucha la ciencia.

Fear does not listen to science.

Fletcher EN

And public health experts have been making that exact argument for decades: blanket travel bans don't stop viruses, they just push them underground and make people afraid to report symptoms.

The evidence from 2014, from COVID, from every major outbreak really, consistently shows that restrictions on whole populations, rather than targeted screening, are more about optics than epidemiology.

Octavio ES

Pero los políticos quieren hacer algo.

But politicians want to do something.

Los ciudadanos quieren ver que el gobierno actúa.

Citizens want to see that the government acts.

Fletcher EN

That's the political logic, yes, and it's real.

Doing something visible matters when people are scared, even if the visible thing isn't the most effective thing.

I don't dismiss it entirely.

But there's a cost, and the cost is usually paid by people from the affected country who had nothing to do with the outbreak and find themselves suddenly suspect.

Octavio ES

El Congo tiene muchos millones de personas.

Congo has many millions of people.

Solo algunas están enfermas.

Only some are sick.

Fletcher EN

About 110 million people.

And the outbreak is geographically concentrated in the east, in provinces like South Kivu and Ituri that are as far from Kinshasa as London is from Istanbul.

Treating everyone with a Congolese passport as a potential carrier is, at minimum, a failure of proportion.

Octavio ES

Y también hay un problema para el fútbol.

And there is also a problem for football.

El equipo del Congo cancela su preparación para el Mundial.

The Congo team cancels its preparation for the World Cup.

Fletcher EN

Which I think is actually a telling detail.

The DR Congo national team qualified for the World Cup, which is a huge deal for a country that hasn't been to a World Cup since 1974.

And now they've had to cancel a three-day training camp and a fan farewell event in Kinshasa because of Ebola fears.

The outbreak is costing them that moment.

Octavio ES

Para muchos congoleños, el Mundial es muy importante.

For many Congolese people, the World Cup is very important.

Es un momento de alegría en un país con muchos problemas.

It is a moment of joy in a country with many problems.

Fletcher EN

That's exactly it.

Sport as relief.

And the cruel irony is that the thing preventing them from celebrating is a disease that the international community has known about for fifty years and still hasn't adequately resourced the capacity to contain at source.

Octavio ES

Hay una palabra en español para esto: 'injusticia'.

There is a word in Spanish for this: 'injusticia'.

Fletcher EN

Injustice.

Yeah, that covers it.

And I'd add that the WHO report framing this as a superspreading event that went undetected for two months is, in a way, both a failure and a kind of honesty.

They're admitting the surveillance gap.

The question is what gets done about it before the next outbreak.

Octavio ES

Después de la pandemia de COVID, el mundo dice: vamos a mejorar.

After the COVID pandemic, the world says: we are going to improve.

Pero no es fácil.

But it is not easy.

Fletcher EN

COVID was supposed to be the lesson that stuck.

Every pandemic simulation, every global health framework going back to SARS in 2003 had essentially predicted COVID.

And then COVID happened and it was still catastrophic.

Now we're watching an Ebola outbreak that was invisible for two months, and I genuinely wonder what it takes.

Octavio ES

Cuesta dinero.

It costs money.

Y los países ricos no quieren gastar dinero en el Congo.

And rich countries do not want to spend money on Congo.

Fletcher EN

Until it arrives at their airports.

Then suddenly it costs nothing to redirect a whole plane.

Octavio ES

Exacto.

Exactly.

Es más barato ayudar antes que tener miedo después.

It is cheaper to help before than to be afraid afterwards.

Fletcher EN

Every public health economist will tell you the same thing: a dollar spent on surveillance and local response capacity is worth fifty dollars spent on crisis management after a virus is already moving.

But that math has never quite convinced the people holding the budget.

Octavio ES

Y mientras tanto, el pasajero del avión está en Montreal.

And meanwhile, the passenger on the plane is in Montreal.

Probablemente está bien.

Probably he is fine.

Pero tiene miedo.

But he is afraid.

Fletcher EN

That detail stays with me.

Whoever that person is, they boarded in Paris, probably had a connection, maybe had family or work in Detroit.

And they ended up in a completely different country because of their passport.

That's the human scale of this story, next to all the epidemiology.

Octavio ES

Oye, Fletcher, tú dices 'quienquiera'.

Hey, Fletcher, you say 'quienquiera'.

Esa palabra es interesante.

That word is interesting.

Fletcher EN

I was waiting for you to catch something I said and turn it into a grammar lesson.

Octavio ES

No es una lección.

It is not a lesson.

Es una palabra bonita.

It is a beautiful word.

'Quienquiera' significa 'whoever'.

'Quienquiera' means 'whoever'.

Es como 'cualquiera', pero para personas.

It is like 'cualquiera', but for people.

Fletcher EN

So 'cualquiera' is 'whatever' or 'anyone,' and 'quienquiera' is specifically 'whoever,' as in a specific unknown person.

And they both have that '-quiera' ending, which I'm guessing carries the sense of indefiniteness?

Octavio ES

Exacto.

Exactly.

'Quiera' viene del verbo 'querer'.

'Quiera' comes from the verb 'querer'.

Literalmente es 'who may want to be'.

Literally it is 'who may want to be'.

Es poético, ¿no?

It is poetic, right?

Fletcher EN

Whoever wants to be.

I like that.

The language built in a kind of philosophical openness about unknown people.

Though I imagine if I tried to use 'quienquiera' in a sentence right now I'd end up telling someone I was very pregnant again.

Octavio ES

Sí, esa historia no tiene fin.

Yes, that story has no end.

Pero intenta: 'quienquiera que sea ese pasajero, espero que esté bien'.

But try: 'whoever that passenger may be, I hope he is well'.

Fletcher EN

Quienquiera que sea ese pasajero, espero que esté bien.

How was that?

Octavio ES

Perfecto.

Perfect.

Y una frase muy humana para terminar este tema.

And a very human phrase to end this topic.
