How Health Systems Can Spot Risk Before a Crisis

Cancer claims 10 million lives each year, the global shortage of health workers runs into the millions, and in some parts of the world, a single mosquito bite can be fatal. These challenges may seem very different. Yet they share a common element in how many health systems operate: risk is often recognised only after it has become illness, outbreak or crisis.

By then, a disease may have advanced, transmission of disease may be under way, or an already stretched workforce may be managing consequences that earlier action could have reduced. The opportunity is to move that point of intervention earlier. This is what anticipatory health means in practice: using signals that already exist, at the bedside, in communities, and in routine health data, to help people and health systems act sooner.

It is not prediction for its own sake. The value lies in connecting early and everyday signals to a timely, practical response.
