International Health is a field of study and practice focused on improving population health and achieving health equity worldwide through actions and agreements that go beyond national borders. Unlike public health, which mainly operates within a country, international health deals with cross-border determinants of health, responding to disease outbreaks that don’t respect borders, and navigating the complex diplomatic and economic relationships that influence global well-being. In our hyperconnected world—where a new viral variant can cross continents within hours—understanding international health isn’t just academic; it’s a practical necessity for national security, including the United States and Brazil.
In this comprehensive guide, you will discover:
- The precise definition of international health and how it differs from global health
- The critical role of the World Health Organization (WHO) and other key players
- Historical milestones and regulatory frameworks shaping health today
- How the United States and Brazil are positioned in the international health arena
- Current major challenges, from pandemics to health diplomacy
📍 What Is International Health? A Comprehensive Introduction
The question “what is international health?” is fundamental. Simply put, it’s a field dedicated to health issues best addressed through health cooperation across borders, involving governments, multilateral agencies, and NGOs. Its main goal is to protect populations from health threats originating beyond their borders and to promote well-being through collective actions.
📍 What Is International Health? A Comprehensive Introduction
The question “what is international health?” is a fundamental starting point. Simply put, it’s a field dedicated to health issues best addressed through global health cooperation, involving governments, multilateral organizations, and NGOs. Its main goal is to protect populations from health threats that originate beyond their borders and to promote well-being through collective action.
Definition and Key Concept
International health can be defined as the set of efforts to identify and address health challenges that are inherently transboundary. These include:
- Transnational diseases: Pandemics such as COVID-19, H5N1 bird flu, and Ebola
- Global health risks: Antimicrobial resistance, climate change, and air pollution
- Trade and health: Regulation of food, medicines, and tobacco products
It’s common to see confusion between these terms. Global health is a broader and more inclusive concept, focused on the health of the world’s population and on equity, emphasizing issues that affect all humanity regardless of borders. On the other hand, international public health typically refers to the practical application of public health principles in international settings, such as implementing vaccination programs across multiple countries.
PRO TIP: Think of international health as “health diplomacy” — the negotiation table where countries agree to cooperate. Global health is the broader humanitarian cause that motivates this cooperation. Learn more about Community Health: The Ultimate Guide for 2024 and Health Management: The Ultimate Guide for 2024
Objectives and Scope of Action

Objectives and Scope of Action
The goals of international health are ambitious and critical for worldwide stability. They include:
- Preventing the international spread of diseases: Through surveillance systems and rapid alert mechanisms
- Protecting against health risks in trade and travel: Ensuring products and people move safely
- Empowering national health systems: Strengthening countries to detect and respond locally to threats
- Promoting health equity: Working to reduce stark disparities between wealthy and poor nations
A clear example of this effort is the International Health Regulations (IHR), a legally binding agreement adopted by 196 countries designed to help the global community prevent and respond to serious public health risks that have the potential to spread worldwide.
Why is International Health Important?
The significance of international health was made painfully clear by the COVID-19 pandemic. A virus that originated in a Chinese city brought the global economy to a halt, claimed millions of lives, and brutally exposed our interdependence. WHO data shows that the pandemic caused an estimated excess of 14.9 million deaths worldwide in 2020 and 2021 (Source: WHO, 2022). This event was not an isolated case.

Why Is International Health Important?
The importance of international health was made crystal clear during the COVID-19 pandemic. A virus that originated in a Chinese city shut down the global economy, took millions of lives, and starkly revealed our interconnectedness. WHO data shows that the pandemic resulted in an estimated excess of 14.9 million deaths worldwide in 2020 and 2021 (Source: WHO, 2022). This was not an isolated incident.
- Globalization accelerates threats: An outbreak anywhere is a threat everywhere. Air travel connects remote populations to major cities in less than 24 hours
- Unresolved chronic threats: Antimicrobial resistance could cause up to 10 million deaths annually by 2050 if left unchecked (Source: Review on Antimicrobial Resistance, 2016)
- Investing in international health is investing in national security: A study by the Commission on a Global Health Risk Framework for the Future estimates that annual preparedness costs around $4.5 billion, whereas a severe pandemic like the 1918 flu could cost the global economy over $6 trillion
Therefore, international cooperation in health is the only viable defense against these systemic crises.
🌍 The Pillars of International Health: Structure and Collaboration
The architecture of global health is supported by a complex network of organizations, each with its mandate and area of expertise. Understanding who these actors are is essential to grasp how decisions are made and put into action.
World Health Organization (WHO): The Global Leader
The World Health Organization (WHO), established in 1948, is the United Nations agency responsible for international health. With 194 member countries—including the U.S.—its mission is to promote health, keep the world safe, and serve the vulnerable.

What Are the Biggest Challenges in International Health Today?
These challenges are interconnected and complex, pushing the limits of international health cooperation.
- Health Equity: The gap between wealthy and low-income countries is stark. While developed nations have access to cutting-edge medicines, nearly half of the world’s population still lacks essential health services (Source: WHO/World Bank, 2021). The unequal distribution of COVID-19 vaccines was a recent and painful example.
- Climate Change: Global warming is shifting the distribution of vector-borne diseases like malaria and dengue, increasing the frequency of natural disasters that strain healthcare systems, and threatening food and water security.
- Antimicrobial Resistance (AMR): The ability of bacteria, viruses, and parasites to resist medications can make common infections untreatable. AMR is responsible for over 1.2 million deaths annually—and that number could jump significantly (Source: The Lancet, 2022).
- Pandemic Threats: COVID-19 demonstrated that the world remains vulnerable. The next pandemic, often referred to as “Disease X” by the WHO, is a matter of “when,” not “if.”
- Misinformation (Infodemic): The rapid spread of false information during health crises erodes public trust, discourages adherence to preventive measures, and complicates efforts by health authorities.
Migration and Health: An Emerging Priority
The challenges are interconnected and complex, pushing the limits of international health cooperation.
- Health Equity: The gap between wealthy and developing countries is stark. While developed nations have access to cutting-edge medicines, nearly half the world’s population still lacks essential healthcare services (Source: WHO/World Bank, 2021). The unequal distribution of vaccines during COVID-19 was a recent and painful example.
- Climate Change: Global warming alters the spread of vector-borne diseases such as malaria and dengue, increases the frequency of natural disasters that overwhelm healthcare systems, and threatens food and water security.
- Antimicrobial Resistance (AMR): The ability of bacteria, viruses, and parasites to withstand medications can make common infections untreatable. AMR causes over 1.2 million deaths annually directly, and this number could rise sharply (Source: The Lancet, 2022).
- Pandemic Threats: COVID-19 showed us that the world remains vulnerable. The next pandemic, often called “Disease X” by the WHO, is a matter of “when,” not “if.”
- Misinformation (Infodemic): The rapid spread of false information during health crises undermines public trust, discourages adherence to preventive measures, and complicates efforts by health authorities.
Migration and Health: An Emerging Issue
Mass migration, whether driven by conflict, disasters, or economic reasons, puts significant pressure on healthcare systems in host countries and poses specific health risks for migrants. International health must develop policies to ensure access to care for this vulnerable population without overloading local services, integrating health into broader discussions on migration and health.
Pandemic Preparedness and Lessons for the Future
Lessons from COVID-19 are being incorporated. There’s a growing consensus that the world needs a stronger, better-funded system for pandemic prevention and preparedness.

How Does Brazil Participate in Global Health?
Brazil plays an active role in international health, participating as a Member State of WHO and PAHO, where it contributes financially and advocates for strategic positions such as universal access to medicines. The country is also known for South-South cooperation, sharing technical expertise with other developing nations, especially in Africa, through institutions like Fiocruz. Additionally, the Unified Health System (SUS) serves as an international reference model, and its local vaccine manufacturing capacity reinforces Brazil’s role in health diplomacy.

What Is a Public Health Emergency of International Concern (PHEIC)?
A Public Health Emergency of International Concern (PHEIC) is a formal declaration issued by WHO. It is triggered when an event is deemed serious, sudden, unusual, or unexpected; has implications for public health beyond the affected country’s borders; and requires immediate international action. The declaration of a PHEIC, like with COVID-19, acts as a global warning, mobilizing resources and coordinating international efforts to contain the threat. It’s not a common measure and follows the criteria established in the International Health Regulations (IHR).

What Is a Public Health Emergency of International Concern (PHEIC)?
A Public Health Emergency of International Concern (PHEIC) is a formal declaration issued by the World Health Organization (WHO). It is activated when an event is considered serious, sudden, unusual, or unexpected; has implications for public health beyond the affected country’s borders; and demands immediate international action. When a PHEIC is declared — as with COVID-19 — it serves as a global alert, mobilizing resources and coordinating worldwide efforts to contain the threat. This is not a routine measure and follows the criteria set out in the International Health Regulations (IHR).
Why Is the International Health Regulations (IHR) Important?
The International Health Regulations (IHR) is a legally binding agreement for 196 countries, including the U.S., aimed at preventing the international spread of diseases, protecting against health risks, and avoiding unnecessary interference with international travel and trade. Its significance lies in establishing a standardized framework for countries to detect, notify, and respond to public health events, strengthening global disease surveillance. The revised 2005 IHR forms the backbone of global pandemic preparedness and response efforts in public health worldwide.
What Are the Biggest Challenges in Global Health Today?
Today’s global health challenges are complex and interconnected. Health equity remains critical, with stark disparities between wealthy and low-income nations. Climate change is shifting disease patterns and increasing the frequency of natural disasters. Antimicrobial resistance (AMR) threatens to make common infections untreatable. The constant risk of new pandemics calls for resilient preparedness systems. Lastly, infodemic — the spread of misinformation — undermines public trust and hampers crisis response, posing a major obstacle to international health cooperation.
