When you hand someone a microphone to celebrate them, most people tell you a success story. At this event, a teacher used his moment to confess a problem he cannot solve, and a lecturer described smuggling climate change into a medical curriculum. The last of three articles on the 4 June 2026 Teach to Reach launch event, this is about the leaders no one appointed, and why the people doing the most important work in global health rarely hold a title that says so.
The room was too hot to think in.
“Can you just stop, our brains cannot assimilate,” the medical students in Ebonyi State, Nigeria, told their physiology lecturer, asking her to break off in the heat.
Most teachers would open a window.
Cordilia Iyare looked at the sweating room and told them the heat was the lesson.
“I said, that is climate change already.”
In that instant she did something no one had asked her to do and no curriculum required.
She turned a complaint about the weather into an education about the planet, and her students into people who would carry it.
This is what leadership looks like when it has no title attached, and it is what the 4 June 2026 Teach to Reach launch event set out to find and name.
Teach to Reach, run by The Geneva Learning Foundation (TGLF), is the largest peer learning event in global health since its January 2021 launch. The last edition drew more than 24,000 health and humanitarian workers from over 70 countries.
Two of its design choices matter for this story.
TGLF frames the people who take part not as learners or beneficiaries but as leaders and partners, because many of them already lead teams, health facilities, and local organisations.
And it certifies contribution rather than attendance: you are recognised not for showing up but for sharing an experience that helps a colleague.
Every monthly launch event reserves time to honour Scholars, and it would be easy to mistake that for a courtesy, a warm interlude between the serious parts.
It is the opposite.
The Scholars the event honours are not thanked for finishing a course.
They are recognised because they took an idea from a course and changed something in the world that no one ordered them to change, and then pulled other people along with them.
The first article in this series described the whole event.
This one asks a harder question: when TGLF honours a frontline worker, what exactly is it claiming, and why should anyone outside that worker’s clinic care?
The lecturer who taught a subject that was not on the syllabus
Climate change is not in the medical curriculum Cordilia Iyare teaches.
She said so flatly.
“It is not part of our curriculum, it is nowhere near it, it is not even related to it.”
A lesser teacher would have left it there.
Iyare found the crack in the wall instead.
She teaches thermoregulation, body temperature, the body’s response to heat, and she realised she could not honestly teach those things while pretending the air outside the body was not getting hotter.
So she built a bridge her syllabus did not authorise.
She made her students draw the chain themselves.
“A pregnant woman who is exposed to higher temperature comes down mostly with serious prenatal stress. And prenatal stress can program for some adult diseases in the children. So I was able to let them understand that some of the diseases we fight were programmed when the mothers were exposed to heat.”
Her students had resisted at first, filing climate under someone else’s job.
“They all saw climate change as a public health issue, environmental issues, the government should get involved, we are not affected.”
She did not argue them out of it.
She let the hot classroom do the arguing, and reframed their discomfort as evidence.
Here is why a reader should care, and it is bigger than one classroom.
Iyare arrived, on her own, at the insight that the entire climate-and-health field has been struggling to operationalise.
She wrote it down for the event in a single sentence.
“I used to think that if we give people health information, behaviour will change. But people may understand the advice and still be unable to act because of poverty, weak infrastructure, or competing survival needs. Sometimes it begins with changing the questions we ask in class.”
A physiology lecturer in Nigeria independently derived a truth that defeats most public health campaigns, that information does not equal action, and then acted on it by redesigning how she teaches.
She is now proposing a multidisciplinary curriculum reform, which she carried to the United Kingdom, where reviewers told her to prove it first with a pilot study.
It started with The Geneva Learning Foundation’s first climate change and health peer learning course, sent to her by a husband who knew she cared.

It has become a colleague network, a changed cohort of future doctors, and a research programme.
That is the return on honouring the right person.
The teacher who used his moment of honour to indict the system
When TGLF gives a Scholar the floor to share a triumph, most share a triumph.
Acha Achi, who teaches at a midwifery and nursing training school in Cameroon, did something braver.
He used the spotlight to describe a problem he cannot solve, and in doing so he held a mirror up to the very kind of education the event was celebrating.
“I may not have a success story yet, but rather a challenge,” he had written.
His subject is the equity of access to sexual and reproductive health services for adolescent girls, “in a context where culture forbids and health policy excludes.”
He has pregnant students.
He has students who are nursing mothers.
And he can teach equity all day without changing what happens to a girl when she walks toward a clinic.
Live, he sharpened the contradiction until it cut.
“Some of these courses are taught, but it becomes like teaching to future health leaders, but the practical aspect of how it works on the field is really challenging. The culture and the policy has not yet accepted that children of less than 18 can move to a hospital and request family planning. So how do I move from just theoretically teaching students of what they could do when they become professionals, and make it work?”
Read what he just did.
Offered a platform built to celebrate learning, he told the room that learning is not enough, that the gap between a trained midwife and a girl who cannot legally reach her is not a knowledge gap but a wall of policy and culture.
That is leadership of a rare kind, the refusal to perform success when the honest report is an unsolved problem.
And it is exactly what the platform is for, because a problem said out loud in front of thousands of peers is a problem that can find allies.
The event pointed him toward the courses closest to his fight, on gender-based violence, on newborn care, on the privatization of health, and he had already enrolled.

His unsolved problem did not stay locked in one school in Cameroon.
It became a question the network now carries with him.
A pattern, not a handful of exceptions
The two Scholars who spoke aloud were the visible edge of something wider.
The slide deck carried more than a dozen written contributions from across the network, and read together they prove that this kind of leadership is not rare luck.
It is what happens routinely when frontline workers are given the tools and the standing to act.
Basile Ngontcha, a community health advocate in Yaounde, Cameroon, watched a colleague fail to persuade a Muslim community to accept the polio vaccine, and instead of pushing harder he rebuilt the response around trust.
“I saw that his team had no Muslim members and faced language barriers. We rescheduled the campaign, recruited Muslim community workers, and met the imam and a highly respected traditional birth attendant. With posters and explanations in Fulfulde and Hausa, families came forward. We vaccinated about thirty children in four days.”
He did not deliver a message harder.
He changed who was delivering it.
Matilda Ogechi Nwanokwu works to reach children in Zamfara State, Nigeria, who have never received a single vaccine, in country where the journey itself can be lethal.
She described a morning that would end most programmes.
“Health workers travelling to our training were stopped by bandits, who abducted two women among them. The others still came to the training and told us what happened with unsettling calm. They had made peace with the risk, because if they stopped every time danger struck, the work would never get done.” From that morning she drew a definition that belongs in any honest account of global health. “They taught me that resilience is the infrastructure of public health in fragile settings.”
Hassan Ali Indhoy, a doctor in the Middle Shabelle Region of Somalia, distilled an entire philosophy of care into one newborn.
“A newborn was brought to our hospital on the second day of life with bleeding from the umbilical stump. The baby had been born at home. We admitted the baby, gave vitamin K, and provided close supportive care. The bleeding stopped, feeding resumed, and the baby was discharged in stable condition. This taught me how lifesaving simple preventive care can be.”

Ezeorah Elizabeth Nnenna, an immunization consultant in Ebonyi State who also spoke live in the Bundibugyo dialogue, refused to win a vaccine refusal by force. “One boy at a school refused vaccination, even when threatened with the police. Instead of forcing him, I used an equity lens to look for the root cause. We visited his home and learned the refusal came from his parents’ religious beliefs. After we met the parents and religious leaders, the boy was vaccinated. I learned that almost every problem has a root cause to find.”
The same instinct runs through the rest.
Dr Vikas Dubey, in Madhya Pradesh, India, turned a climate lesson into a bedside tool.
“I designed a simple checklist for patients aged 60 and above, and I trained pre-operative nurses to watch for heat-related confusion.”
Adrienne Vanessa Kouatchouang, after more than twelve years against gender-based violence in Cameroon, learned to turn the lesson on herself. “Caring for others is not enough, you must also learn to care for yourself.”
Anguzu Juma, running a medical camp with the Uganda Red Cross, named the unglamorous truth underneath all of it. “Good intentions are not enough. Planning, communication, and community ownership are what create change.”
Why honouring them is an argument, not a kindness
Lay these voices side by side and the common thread is unmistakable.
Nobody handed any of these people a mandate.
Each took a course, found the one problem in their own setting that the course lit up, and acted without waiting for permission.
Then most did the thing that separates leadership from competence: they changed the people around them.
Iyare changed her colleagues and her students.
Basile changed who staffed a vaccination team.
Nwanokwu’s colleagues taught each other how to keep moving under threat.
A private act of learning became a public change others could see and copy.
This is the leadership that org charts cannot see, because it does not sit on one.
It is the leadership of the first node, the person who notices first and moves first, which is exactly how the climate report describes the community health worker standing at the front of the climate signal.
So when TGLF puts Cordilia Iyare and Acha Achi on screen, it is not being polite.
It is making an argument about where the knowledge and the leadership that global health most needs actually reside, and the argument cuts against the field’s instinct to locate both in capitals and institutions.
The point of the alumni segment, named on the slide that introduces it, is plain enough: these are stories of leadership and change.
The claim underneath it is that leadership and change are happening, right now, in a physiology lecture hall in Ebonyi State and a midwifery school in Cameroon, and that the field will keep missing them until it learns to look.
There is a final turn worth noticing.
The Scholars who moved the room most were not the ones with the cleanest success stories.
They were Acha Achi, naming a wall he cannot climb, and Matilda Nwanokwu, turning an abduction into a lesson.
A network that can hold an unsolved problem and an unbearable morning in public, without flinching and without forcing them into a tidy ending, is a network strong enough to help carry them.
That is what the event honoured, and it is worth asking, of your own work, who around you is leading like this without a title, and whether anyone has yet given them the second microphone.
