Global awareness begins with understanding that our world is interconnected—and that health threats, environmental hazards, information, people and ideas can move across borders.
Learn how the world recognizes health events, how trusted public-health systems communicate, how to evaluate information, and what you can do when a public-health threat is announced.
A political border can organize countries and governments, but many forces that influence health do not stop at borders.
People, goods, information, infectious agents, pollution, smoke, dust, water and environmental hazards can move through interconnected systems.
Understanding our connections helps us recognize inequality, respect different perspectives, use evidence responsibly and contribute to healthier communities.
Start by understanding our interconnected world. Then learn how health events are recognized and communicated. Finally, move from awareness to responsible action.
Explore culture, diversity, migration, inequality, climate, environment and the ways people and natural systems are connected.
Discover why viruses, dust, wildfire smoke, PM₂.₅, ozone, UV radiation, oil spills and some radiological hazards can cross political borders.
Explore Layer 1 →Learn how public-health systems use surveillance, assessment, communication and coordination to recognize and respond to health threats.
Explore outbreak, surge, epidemic, pandemic, PHEIC, Pandemic Emergency, IHR, the WHO Pandemic Agreement, vaccines, Points of Entry and RCCE.
Explore Layer 2 →Ask the practical adolescent question: What should I know and what can I do?
Move from awareness to understanding, participation and responsible action—for yourself, your family, school, community, country and the wider world.
Explore Layer 3 →When health information is circulating, ask:
SOURCE
— Who produced it?
DATE
— Is it current?
EVIDENCE
— What supports the claim?
CONTEXT
— What might be missing?
CORROBORATION
— Do reliable independent sources agree?
PURPOSE
— Inform, persuade, entertain, sell or provoke?
SHARE?
— Could sharing it cause harm?
For current public-health decisions, always verify with WHO and the appropriate government/public-health authority.
GHE teaches learners how to think critically about information—but GHE is not the authority that announces public-health emergencies or gives official public-health instructions.
For current health threats, alerts, recommendations and official measures, go directly to the World Health Organization and the relevant government or public-health authority.
WHO Headquarters, Regional Offices and Country Offices may provide global and regional information, while governments and their public-health authorities make and implement decisions within their jurisdictions.
Educational resources can help learners understand epidemiology, global health and public-health concepts.
GHE may connect learners with educational resources such as NextGenU, but educational resources are not substitutes for current official public-health decisions.
And once a trusted public-health authority announces a public-health threat, what should I know and do?
Surveillance, assessment, communication, coordination and response help societies understand changing health risks.
Your role changes with the situation—but responsible participation always begins with reliable information, respect, appropriate action and care for others.
