Although the world has witnessed tremendous economic growth and technological advancements in the past few decades, today there are still over 600 million people living in extreme poverty. Most of these people live in the least developed countries (LDCs), and while regular visits to our family doctors have become a routine in our daily lives, people who live in LDCs have very limited or even no access to healthcare. When we examine the details of healthcare expenditure data, the numbers are staggering: Developed countries (e.g., the Organization for Economic Co-operation and Development, or OECD countries) such as the U.S. spend roughly 10% of their GDP on healthcare, yet many LDCs don't even have 5% of their GDP to spare on healthcare. Realizing the seriousness of this problem, the United Nations Sustainable Development Goal 3 (SDG 3) has declared a universal health goal to ensure healthy lives and promote well-being for all by 2030.
