There is a pattern that has been repeating for decades and that continues to define how the world responds to infectious diseases. The outbreak occurs. The emergency response mobilises. The headlines multiply. Containment arrives. And then, silence, until the next one.

In 2025, Africa CDC documented a simultaneous increase in outbreaks of cholera, mpox and Marburg virus across several African countries, warning of overstretched resources and persistent challenges in preparedness. The DRC declared the end of its 16th Ebola outbreak. The Marburg virus appeared for the first time in Ethiopia. These are not isolated events. They are points in a pattern.

The problem is not the disease. The problem is what needs to exist before it emerges.

Over more than two decades working with organisations in complex environments, in Africa, the Middle East, Asia and Europe, I have learned that preparedness for communicable diseases rarely fails at the moment of crisis. It fails much earlier. It fails when no one asked the right question while there was still time to answer it: what are the specific risks of our environment, and do we have a plan to manage them?

Outbreaks are not stopped by emergency response systems. They are contained by organisations that, before any alert, had assessed their risks, trained their teams, established protocols and created reporting channels that work on the ground. The difference between a case and an outbreak is, very often, that invisible architecture that exists, or does not exist, long before the first symptom.

Africa faces today a convergence of pressures that makes this question urgent. Accelerated economic growth, the expansion of operations in remote environments, the mobility of international teams, and the constraints of some public health systems create conditions in which an organisation without adequate preparedness is simultaneously vulnerable and part of the problem.

The question is not whether your organisation will face a communicable disease risk. The question is whether, when that happens, there will be something built to contain it.
