The Nexus cycle in Health Nexus is the eight-step path by which a question in the health and biosecurity field becomes evidence, a Foundry build, an organized community, a controlled test, a publication and a decision taken by the competent authority. Here the evidence step rests on epidemiology and public health science as well as molecular and life sciences, and findings feed Global Sector Risk and Resilience.

Layers and dates
A Health Nexus cycle often starts with a ministry's preparedness question, draws on surveillance, facility and supply data, builds capacity and supply models, tests them in a hospital continuity exercise and returns options to the health authority.
| Step | Owner |
|---|---|
| Question | National, regional or institutional priority |
| Evidence | STEM foundation of the platform |
| Build | Nexus Foundry |
| Organize | Nexus Ecosystem: community, chapters, councils, national cells |
| Test | Nexus Universe (independent site) |
| Publish | Nexus Reports |
| Decide | Competent authorities and institutions, through Nexus Rails |
| Renew | Corrections and the next annual agenda |
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Nexus cycle | The eight-step loop by which work moves in every Nexus field: question, evidence, build, organize, test, publish, decide and renew, each step with a named owner. |
| Competent authority | The body that a law or regulation designates to exercise a given power or duty, such as a supervisor, a civil protection agency or a ministry; only it can take the decisions the law assigns to it. |
| Peer review | Evaluation of a work by independent experts in the field before publication. |
| International Health Regulations | The legally binding WHO instrument that sets countries' duties to detect, assess, report and respond to public health events of international concern. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
