Why investing in global health protects families, strengthens the NHS, and keeps the UK safe
When we think about national security, we often picture borders, defence systems, or emergency responses. But one of the strongest protections Britain has begins far beyond our shores — in global health.
Diseases do not recognise borders. In an interconnected world, health threats travel faster than ever before. Investing in global health is not charity; it is a practical, proven way to protect lives here in the UK.
The world is connected — our health must be too
Infectious diseases spread through travel, trade, and climate-driven environmental change. What starts as a local outbreak can quickly become a global crisis, as we saw during COVID-19.
By strengthening disease surveillance, vaccination programmes, and health systems worldwide, the UK helps stop outbreaks before they reach our communities.
Preventing disease abroad reduces pressure at home.
Early action saves lives, reduces disruption, and protects the NHS from being overwhelmed by preventable crises.
Protecting the NHS starts beyond the UK
The NHS is one of Britain’s greatest assets — but it is under increasing strain. Global health threats directly affect NHS demand, staffing pressures, and resources.
When diseases spread unchecked internationally, the consequences are felt in UK hospitals:
More emergency admissions
Delayed routine care
Increased costs to the health system
Investing in global prevention is one of the most effective ways to reduce future NHS burden while keeping care accessible for everyone.
Science, innovation, and British leadership
The UK is a global leader in medical research, public health expertise, and life sciences. From vaccine development to disease surveillance technologies, British science saves lives worldwide.
Supporting global health:
Drives innovation and research
Strengthens the UK’s science and tech sector
Builds international partnerships and trust
This leadership doesn’t just benefit others — it fuels economic growth and resilience here at home.
Health security is national security
Antimicrobial resistance, emerging infections, and climate-driven disease spread are among the biggest threats facing the UK today. These challenges cannot be solved by any one country alone.
A healthier world means:
Fewer global outbreaks
Stronger international early-warning systems
Greater stability in an uncertain world
Put simply, global health investment makes Britain safer.
