Questions & Answers

Q: What is global health?

Global health is a public health approach focused on improving health for everyone in the world. It also aims to eliminate health-equity gaps resulting from factors such as nationality, income, and gender.

Q: Why is human health a global concern?

People around the world are highly interconnected, and pathogens can cross political and geographic boundaries through trade, travel, and tourism. With over 7 billion people living in about 200 countries, protecting health often requires coordinated international action.

Q: When was the World Health Organization established?

The World Health Organization was established in April 1948 as a United Nations special agency devoted to monitoring and improving global health. Its constitution set the objective of helping all peoples attain the highest possible level of health.

Q: What does the World Health Organization do?

The WHO sets international health standards and collects and analyzes health data from around the world. It also monitors new and existing diseases and helps countries coordinate emergency responses and research.

Q: What are communicable diseases?

Communicable diseases spread from one living thing to another through pathogens such as bacteria and viruses. Those pathogens can travel through respiratory droplets, blood, saliva, and other routes.

Q: Why do communicable diseases require a globally coordinated response?

Pathogens do not stop at national borders and can move internationally with people and resources. Without coordination, a disease suppressed in one part of the world can reappear elsewhere, making elimination resemble a game of whack-a-mole.

Q: How was smallpox eradicated?

In 1959, the WHO adopted the mission of eradicating smallpox, which required ensuring that nobody on Earth still had the disease. After coordinated interventions across dozens of countries and mass education and vaccination campaigns, the last confirmed case of naturally acquired smallpox was identified in Somalia in 1977.

Q: What causes most deaths worldwide today?

Most deaths today are caused by non-communicable, or non-infectious, diseases such as cancer. These conditions are linked to genetic, environmental, and behavioral factors, and their share of deaths increased as communicable-disease rates declined.

Summary & Key Takeaways

• Global Health is a public health approach focused on improving health for all and reducing health equity gaps.

• Communicable diseases, such as malaria and the flu, are not the leading causes of death in most places worldwide.

• Non-communicable diseases, such as cancer and heart disease, are the leading causes of death globally, with their prevalence influenced by a country's income.
