How is global health defined?

Global health is defined as the health of global populations and related issues because it encompasses the health and well-being of communities and individuals across countries and continents, recognizing that health issues can transcend national borders. This definition highlights the interconnectedness of health determinants and outcomes, including the spread of diseases, health equity, and access to medical resources, emphasizing that global health initiatives often require collaborative efforts among nations and organizations.

This perspective is essential for addressing global challenges such as pandemics, health disparities, and the health impacts of climate change, all of which require a coordinated international response to ensure that health improvements benefit populations worldwide. By focusing on the collective health of global populations, this definition reflects the importance of understanding and acting upon health issues that affect people irrespective of geographic or political boundaries.
