01Cycle

How work moves in this field.

A question becomes evidence, a governed build, an organised community, a controlled test, a reviewed publication and, finally, a decision taken by the competent authority under its own rules.

  1. Question Universe National, regional or institutional priority. Question in Health Nexus
  2. Evidence Foundry STEM foundation of the platform. Evidence in Health Nexus
  3. Build Foundry Foundry. Build in Health Nexus
  4. Organise Universe Nexus ecosystem. Organise in Health Nexus
  5. Test Universe Universe (independent site). Test in Health Nexus
  6. Publish Reports Reports. Publish in Health Nexus
  7. Decide Competent authority Competent authorities and institutions, through NXS-RLS (participants, agreements and handoffs). Decide in Health Nexus
  8. Renew Universe Corrections and the next annual agenda. Renew in Health Nexus

Each step of the cycle in the pillar it runs in; the decision stays with the competent authority, outside the programme.

Assembled from the Nexus Standards area profile Health security and One Health: the hazards it names, the systems and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

05The problem

Health systems fail through their dependencies.

A hospital is a dense knot of dependencies. It needs grid power and backup generation, treated water at pressure, medical gases, a cold chain for vaccines and blood, working information systems, road access for staff and ambulances, and a steady flow of medicines produced in a small number of places. Most of these sit outside the health sector and outside the control of the people who run the hospital.

That is why health crises rarely stay inside health. A heatwave raises admissions while it strains the grid that cools wards. A flood closes the road that night-shift nurses use and contaminates the water a dialysis unit depends on. An outbreak absorbs beds, staff and protective equipment, so that elective surgery, maternal care and chronic disease management are deferred, and the excess harm often appears months later in people who never caught the infection. Shortages in one country’s supply of an active ingredient can surface as missing antibiotics in another.

Epidemiology explains who is exposed and how risk is distributed; systems science explains how load, delay and feedback turn local stress into system-wide failure. Health Nexus brings the two together, so that preparedness is judged by whether essential services continue, not only by whether a plan exists.

07Overview

What Health Nexus does.

Health security is the protection of populations from acute public health events that threaten health across communities and borders, together with the resilience of the systems that deliver care. Health Nexus studies both as properties of whole systems: hospitals and their power, water, staff and supplies, surveillance and laboratories, environments, and the links between human, animal and ecosystem health. Health authorities decide.

Who it serves

Its community

Public health; hospitals; clinicians; One Health scientists; health informatics.

How it works

Its methods

Epidemiological methods; facility continuity; health services access analysis.

What it produces

Its outputs

Health-system resilience briefs; access maps; One Health evidence.

08Methods and evidence

09GCRI’s mandate in health

What Health Nexus does, and what stays with health authorities.

Health Nexus studies how health systems and threats interact with water, energy, food and nature, and helps countries build the evidence and capability for preparedness and continuity. It gives no clinical advice, declares no emergency, notifies no event under the International Health Regulations and approves no medicine or facility; WHO, national public health institutes, ministries of health and regulators hold those mandates.

Epidemic models and figures on these pages are illustrative unless a page says otherwise; they are never a forecast, a risk assessment of a country or health advice. Readiness is not authority. National health agendas, data and decisions stay national, and personal health data is never published.

10Domains, reports and standards

11Contribute

What epidemiologists, clinicians and communities can add.

  • Evaluations: retrospective evaluations of models and preparedness exercises.
  • Continuity records: how services held or failed in past shocks, aggregated.
  • Community accounts: barriers to care, shared through consent-aware routes.
  • Corrections: through corrections.
12What the platform does

Evidence for the people who keep care running.

Health Nexus is designed to produce evidence that health planners, hospital leaders and public health agencies can examine and use under their own authority.

Methods

Epidemiology and continuity

Epidemiological methods, facility continuity analysis and health services access analysis, each with its data and limits stated.

Outputs

Briefs, maps and evidence

Health-system resilience briefs, access maps and One Health evidence, published as they pass review.

Community

Who it is for

Public health professionals, hospital and clinical leaders, One Health scientists and health informatics specialists.

GCRI does not regulate, certify, license or approve. Health Nexus gives no clinical advice and does not direct care; clinical and public health decisions stay with the competent authorities and providers.

13Foundation and counterparts

Grounded in method, connected across the Consortium.

Health Nexus stewards the canonical description of epidemiology and public health science in the STEM Commons. It also applies probability and statistics, complex systems and agent-based modelling, causal inference and impact evaluation, data engineering and stewardship, molecular and life sciences and biotechnology platforms. The STEM foundation page shows how each is used here.

The same field is seen three ways across the Consortium. At The Global Risks Forum (GRF), Health and Biosecurity Governance convenes the institutions that govern health security across borders. At The Global Risks Alliance (GRA), Insurance Nexus builds shared industry understanding of health and catastrophe exposures. Within GCRI, Biotechnology and Biosecurity covers the life-science research side. See counterparts across the Consortium and the health and biosecurity field gateway.

14Coverage

The areas of health and biosecurity this platform takes on.

Health Nexus studies health security and human wellbeing as properties of whole systems: hospitals and the power, water, staff and supplies they depend on, surveillance and laboratories, the environments people live in, and the links between human, animal and ecosystem health. Its pages set out the science, the data, the methods and the decisions for each part of that system, with every value labelled by its evidence and every limit stated. It prepares evidence; health authorities decide.

Area

Health system continuity

Keeping essential services running through outbreaks, disasters, outages and staff loss, and restoring them afterwards.

Area

One Health

The shared health of people, animals and ecosystems: zoonoses, spillover and antimicrobial resistance across sectors.

Area

Infectious threats

Detection, assessment and readiness for outbreaks, with reporting delays and uncertainty kept visible.

Area

Health equity

Unequal exposure, vulnerability and access to care, measured by population group and by place.

Area

Environmental health

Air pollution, heat, unsafe water and chemical exposure as causes of disease and as demand on services.

Area

Health supply chains

Medicines, vaccines, diagnostics, oxygen and the cold chain, from manufacturer to facility shelf.

Area

Digital health risk

Clinical systems, health data, cyber threats and the algorithms that support clinical and public health decisions.

Area

Healthcare infrastructure

Facility siting, structural and non-structural safety, functional dependencies and recovery after damage.

15Grounding

16Six pillars

How this works across the six pillars.

Health Nexus works through six pillars of one annual programme, led by the Nexus Consortium, with GCRI, GRF and GRA each contributing in its role: explore, experiment and prototype in Labs, build, simulate and prepare in Foundry, convene and test in Universe, codify, correct and apply in Nexus Standards, publish in every format in Reports, teach in the open in Risk Academy.

What the work is read against.

The platform does not set standards. It reads its evidence against the frameworks that competent bodies have adopted, so a finding can be placed where a decision-maker already works.

21Questions

Questions and answers.

Who publishes Health Nexus?
The Global Centre for Risk and Innovation (GCRI) publishes Health Nexus and is responsible for what it publishes. GCRI is a research, development and policy institution. It is not a regulator, and it does not certify, license or approve; its findings carry their methods and uncertainty.
Is Health Nexus active?
Health Nexus is an established platform of The Global Centre for Risk and Innovation. Information and enquiries are open today. 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.
How can I contribute?
Start with the participation paths or write to the contact form. An enquiry receives a reference; it does not create membership, a role or an assignment.
Where are findings published?
Reviewed outputs appear on the publications page, and contributions to the Reports series are listed on Publish in Reports.
Which values on this platform are real?
Indicator names, units, sources, methods and frameworks are real. Levels in figures and canvases are examples in a design. A programme replaces them with labelled evidence it owns.
How do I report an error?
Use corrections and concerns, or write to the integrity concern form. A correction is recorded as a new version, never a silent edit.
Does Health Nexus give medical or clinical advice?
No. It publishes research and evidence about health systems and population health. It does not diagnose, treat, advise individuals or direct clinical practice. Anyone with a health concern should contact a qualified health professional or their local health service.
How is Health Nexus different from Health and Biosecurity Governance at GRF?
Health Nexus does the science: epidemiology, continuity analysis and access mapping. Health and Biosecurity Governance at The Global Risks Forum (GRF) convenes institutions on how health security is governed. Each links to the other so evidence and governance stay connected without either taking the other’s role.
