Lessons in Public Health
Nine essays on what nine years inside WHO Nigeria and Nigeria’s health systems actually teach you — on data, coordination, community trust, surveillance design, and what persists when the funding ends.
Lessons in Public Health: Why Passion Alone Is Not Enough
Lesson 1 of 9: Over nine years into a public health career, the lesson I return to most often is the one that took the longest to truly understand: passion is not a strategy.
Lessons in Public Health: Data Without Context Misleads
Lesson 2 of 9: In over nine years of working with health data across Nigerian states, the most dangerous errors I have seen were not caused by bad data. They were caused by good data interpreted without adequate context.
Lessons in Public Health: The Last Mile Is Where Health Systems Are Won or Lost
Lesson 3 of 9: Health policies designed at the national level are only as effective as their implementation at the community level. The "last mile" is not a delivery problem. It is a design problem.
Lessons in Public Health: Policy Is Not the Enemy of Progress
Lesson 4 of 9: Field practitioners often see policy as bureaucratic obstruction. After working at the intersection of policy and implementation for over nine years, I have come to see it differently.
Lessons in Public Health: Communities Are Not Passive Recipients
Lesson 5 of 9: One of the most damaging assumptions in global health is that communities are blank slates waiting to receive interventions. They are not. They have knowledge, priorities, and agency that any effective programme must engage with.
Lessons in Public Health: Surveillance is a Social Contract
Lesson 6 of 9: Disease surveillance works only when communities participate willingly. That participation is not automatic. It is earned, and it can be lost.
Lessons in Public Health: What Polio Eradication Taught Me About Systems Thinking
Lesson 7 of 9: The global polio eradication programme is one of the most complex public health endeavours ever attempted. Working inside it taught me that you cannot solve a systems problem by optimising one part of the system.
Lessons in Public Health: Coordination is the Hardest Part
Lesson 8 of 9: In public health, the technical solutions are rarely the bottleneck. What slows us down is the human and institutional challenge of getting multiple organisations to move in the same direction at the same time.
Lessons in Public Health: Nine Years In, Here Is What I Know
After over nine years spanning polio eradication, disease surveillance, immunisation, and health systems strengthening across Nigeria, here is an honest account of what the work has taught me.
