The first of three articles on the 4 June 2026 Teach to Reach Launch Event, this is the story of an hour that dissolved every border between the people in the room, and of why a frontline nurse, a markets economist, and a physiology lecturer turned out to belong in the same conversation.
There is no set list.
Thirty minutes before a Teach to Reach launch event goes live, the two hosts do not know who will speak, in what order, or about what.
Guests arrive on the call from a dozen countries and raise their hands on camera.
The hosts watch, sort, and decide in the final minutes.
Reda Sadki and Charlotte Mbuh chat with participants during the countdown to the event.
“These events are not scripted,” Reda Sadki tells newcomers. “Charlotte and I do not know who is actually going to be in the room. And it is in the minutes, in the countdown to the event, that we figure that out.”
A launch event is closer to a jazz set than a webinar.
The musicians are strangers from four continents, the room knows roughly the key, and the music is whatever they make together in the next hour.
What makes this worth writing about is not the format.
It is what the format lets happen.
Teach to Reach is the largest peer learning event in global health, run by The Geneva Learning Foundation (TGLF), and it works by and for the people who do the work rather than the people who manage it.
It began in January 2021 out of an immunization training programme that collided with the COVID-19 pandemic. Led by almost a thousand health workers from 86 countries, the programme morphed into a peer support hub to help recover from shock of the pandemic, then to prepare for the arrival of new vaccines.
The founders learned what they had built almost by accident: at that first conference, participants held more than 14,000 one-to-one networking meetings in three days, and the foundation rebuilt everything around that hunger to connect.
Five years on, more than 24,000 health and humanitarian workers from over 70 countries took part in the last major event, most of them working at facility and district level, half in government and half in civil society, a quarter serving refugees or displaced people, one in five in places with active armed conflict.
TGLF does not call them learners or beneficiaries.
It calls them leaders and partners.
The two largest communities are Nigeria and the Democratic Republic of the Congo, which is the first thing to know about why this particular hour happened the way it did.
Each month, as part of TGLF’s tenth anniversary celebration, a launch event runs for one hour in parallel English and French studios.
On 4 June, in a single unscripted hour, a Nigerian cold-chain consultant with no cases in her country pressed Ugandan responders on how to contain an Ebola outbreak, a humanitarian economist argued for dismantling the way relief agencies work, a physiology lecturer explained how she smuggled climate change into a medical curriculum, and a midwifery teacher used his moment of honour to tell the room what his training cannot fix.
None of them shared a discipline, a country, or a rank.
That is the story.
The borders that organise global health, geography, language, seniority, and the thematic silos that keep malaria people away from climate people away from Ebola people, did not hold in that room.
This article is about why they fell, and what it means that they did.
An agenda the community tore up
The hour was supposed to belong to climate’s nasty effects on health.
TGLF had its twentieth Teach to Reach insights report ready, built on the experiences of more than a thousand health and humanitarian workers, and a new course to launch from it.

Then a strain of Ebola, Bundibugyo virus disease, crossed the border between the Democratic Republic of the Congo and Uganda, and the people the event exists for refused to wait.
“We reorganized what we had planned,” Reda told the audience as the countdown ran, “because TGLF scholars, people who work for health from both Uganda and the Democratic Republic of Congo came to us and said, we want to support each other. We want to learn from each other.”
Sit with the direction of that.
Most convenings decide their subject and then recruit an audience to receive it.
Here the audience reached up and changed the subject.
A foundation that can be redirected by its own community in three days is not running a broadcast.
It is holding open a channel that the people on the front line can seize when something urgent crosses their border, which is exactly what the workers in Uganda and the DRC did.
The whole hour rests on that inversion of who is in charge of the agenda.
The borders start to dissolve in the first ten minutes
The first voice the event chose was, deliberately, the wrong one by conventional logic.
Elizabeth Ezeorah is an immunization and cold-chain consultant in Ebonyi State, Nigeria, a country with no Bundibugyo cases.
She had heard of the outbreak only a week or two earlier, through leaflets.
By the rules of expertise, she had nothing to teach about Ebola.
By the rules of this room, she had the most important thing of all, a real question, and she refused to soften it.
“I want them to tell us, because it has already happened there, how are they combating it? How are they going about containing the spread of that virus? We are not praying, but assuming that it happened, how are they going about the containment?”
The answer crossed a border to reach her.
John Kamulegeya, a Ugandan epidemiologist working in surveillance and contact tracing, did not give her a protocol.
He gave her the words he uses on the ward, where fear empties rooms.
“It is okay to take care of this patient, but you need to take care of yourself, observe the infection prevention and control, and I call the technical people to take care of the situation.”
Then Hillary Okello, who had fought Ebola years earlier in Gulu and was not part of this response at all, addressed people he had never met on the other side of an international line, telling them plainly that the disease had been defeated before and could be defeated again.
A Nigerian asks, a Ugandan answers, and a man who survived a different outbreak reaches across the DRC border to steady strangers.
The geography that fragments the official response into separate national systems simply was not operating.
The second article in this series stays with this conversation, and with what Okello told them, and asks what an epidemiologist should do with it.
Why a markets economist belongs at an Ebola event
The moment that should puzzle a reader is Andrew Gardiner.
What is a humanitarian economist who works on markets doing in the middle of an Ebola dialogue?
The answer is the key to the whole event, because Gardiner has spent a career arguing against exactly the instinct that the global aid system runs on, and that instinct is the same one TGLF is built to refuse.
For decades, he explained, the reflex of relief has been to arrive and build a parallel world.
“The traditional humanitarian response is that the humanitarian community comes in and sets up parallel systems, which run parallel to the existing markets. That itself has an effect on the markets, usually quite negative.”His life’s work is to stop agencies from bulldozing the local capacity that is already there, because “the ability of local markets to respond is usually much quicker and much more adaptive than what humanitarians can do.”
Then he turned the same lens on the outbreak in the room and made the marketplace cut both ways.
“They are a focal point where transmission can occur. But they are also a focal point where information can be disseminated and good practices can be encouraged.”
Hear what he is actually saying, and hear how it rhymes with everything else in the hour.
Do not replace the thing that already works.
Work with it, trust it, build on it.
Gardiner says this about markets.
TGLF says it about knowledge.
The dominant model treats the frontline worker as an empty vessel to be filled by an expert, the way old-style relief treated a local economy as a vacuum to be filled by aid.
The event was one long demonstration of the opposite.
The most authoritative voice on Ebola containment was a facility-level worker, not the platform.
Gardiner was not a digression.
He was the theorist of the very thing the room was doing to the hierarchy of who is allowed to know.
The catalogue is not a menu, it is a mirror
Near the close, the courses scrolled past fast, each a QR code and a line.
Malaria.
Non-communicable diseases in humanitarian settings.
A first-ever course on ageing.
Decolonizing global health.
Two equity courses.
HPV vaccination.
Measles.
Newborn care.
Women inspiring women, drawn from 177 frontline women, some of them, Reda noted, in the room.

To a planner trained in vertical programmes, this looks undisciplined.
Global health is organised into silos, one disease, one budget line, one set of experts each.
A catalogue this wide looks like a foundation that cannot say no.
Look at it instead from where the worker stands, and the logic inverts.
Cordilia Iyare teaches medical physiology in Nigeria, and she put her finger on exactly what the silos cost.
“Usually the medical curriculum is teaching in isolation. You teach these parts in isolation. And so the students do not get to connect both,” she said.
“Now I try to always propose an interdisciplinary and integrated style of teaching where we connect, we start from the environment.”
Her students arrive carrying climate, heat, food insecurity, and infection whether or not the curriculum admits it.
Elizabeth Ezeorah runs cold chains and worries about Ebola in the same week, and credits an equity course with the principle she now works by.
“It taught me that whenever you are doing things with the community, you have to involve them, and if you involve them they will really come in and be part and parcel.”
The midwife who hires her own motorbike to reach a pregnant woman in a flood is doing climate work, maternal work, and transport logistics in a single trip.
No frontline life is siloed.
A worker’s day braids together everything the system files separately.
The breadth of the catalogue is not institutional sprawl.
It is fidelity to the integrated reality of the people the catalogue is for.
The silos are an artefact of how the system funds itself, not of how health is actually lived, and the catalogue refuses them.
Reda named the cost of that breadth without flinching: the courses are open access, funded by TGLF, so that, as Charlotte put it, “you do not have to pay anything out of pocket.”

Trust is the instrument they are all playing
Underneath the improvisation, one thing is being built that makes the rest possible.
When Reda paused mid-hour to mark the foundation’s anniversary, he said the plainest sentence of the day.
“There is no Geneva Learning Foundation without you. That is why we are here. And it makes no sense if we do it without you and if we do not do it together.”
This is not a slogan.
It is the precondition for a Nigerian to be willing to ask a naive question in front of thousands, for a Ugandan to admit that fear nearly emptied a ward, for a teacher to use his honour to confess a failure rather than perform a triumph.
The same word surfaced in the evidence.
The climate and health report’s hardest finding, Reda told the room, is that “trust decides who engages,” and that trust “is built in calm years, not crisis weeks.”
A community in Taraba State refused care, the report found, “because past help never returned.”
Every strand of the hour was an argument that the unit of global health is not the intervention but the relationship, and that relationships do not respect the borders the system draws.
That is why the event can be redirected by its own community in three days, why a markets economist and an epidemiologist and a physiology lecturer can make sense to each other, and why an hour of strangers can feel like one room.
They are not exchanging information.
They are extending trust across distance, and distance, here, means every kind of border at once.
When Charlotte and Reda open the studio, they genuinely do not know what will happen.
What they know is that if they build the trust, set the key, and hand the second microphone to people the system usually talks over, the room will make something none of them could have made alone.
Think back to where the hour began, with hands going up on camera one by one, strangers from four continents signalling that they had something to bring.
Nobody in the studio knew yet what any of them would say.
They raised their hands anyway, and the music started.
That is what these events are, and it is why the next two articles follow the music into its two richest passages, the Bundibugyo dialogue, and the leadership of the Scholars the event set out to honour.
