Health and biosecurity
Health systemic risk is the chance that an outbreak, a supply shock or a slow-burning threat such as antimicrobial resistance overwhelms detection, care and the social systems that keep people able to isolate, work and eat.

The short answer.
Health and biosecurity as a field of risk covers the threats to human health and the capacity of health systems, public health institutions and One Health arrangements to prevent, detect and respond to them. In the Nexus Consortium it is studied as science at GCRI by Health Nexus as well as Biotechnology and Biosecurity, governed at GRF by Health and Biosecurity Governance, and understood financially at GRA by Insurance Nexus; this gateway links those platforms and the methods they share.
Access to care in the Philippines.
How far each division sits from a large city, with the roads and airports that carry patients and supplies, shown for the Philippines as an example geography for this subject.
The field, seen three ways.
Surge capacity, supply chains and the time to detect.
The consequence of an outbreak depends less on the pathogen alone than on how quickly it is detected, how much surge capacity exists in care and laboratories, and whether supply chains for diagnostics, medicines and protective equipment hold when every country needs them at once. Most of these are capacities that can be assessed in advance.
- Detection: event-based and indicator-based surveillance, genomic sequencing access, reporting timeliness.
- Response: health-workforce surge, intensive-care capacity, laboratory throughput.
- Supply: concentration of active pharmaceutical ingredient production and of medical countermeasure manufacturing.
- Society: sick pay, social protection and trust, which set whether public health measures are followed.
International law and assessment frameworks.
| Framework or body | What it governs or supplies |
|---|---|
| International Health Regulations (2005), with the amendments adopted in 2024 | Core capacities, notification duties and the pandemic emergency category |
| WHO Pandemic Agreement | Adopted in 2025; it opens for signature only after its pathogen access and benefit-sharing annex is adopted |
| IHR Monitoring and Evaluation Framework (SPAR, Joint External Evaluation) | Self-assessment and voluntary external evaluation of capacities |
| One Health Joint Plan of Action | Coordination across human, animal, plant and environmental health |
Where health risk meets other fields.
- Nature: land-use change and wildlife trade shape spillover risk.
- Food: animal disease and nutrition status set exposure and vulnerability.
- Climate: heat and vector range shifts.
- Work and society: the capacity of households to follow public health measures.
The science sits on Health Nexus; methods start from epidemiology.

Terms used on this page.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Health security | The activities that minimise the danger and impact of acute public health events endangering the collective health of populations across regions and borders, in WHO usage. |
| International Health Regulations | A binding WHO instrument that sets obligations on states to detect, assess, notify and respond to public health risks that may spread internationally. |
| Health system resilience | The capacity of health actors, institutions and populations to prepare for, absorb and recover from shocks while keeping essential services running. |
| One Health | An integrated approach that aims to balance and optimise the health of people, animals and ecosystems, as the Quadripartite organizations define it. |
