Over the past few decades, the world has seen major advancements in health and largely as a result, people are generally living longer, healthier lives. However, serious challenges to global health remain, ranging from dealing with pandemics to the rise of noncommunicable diseases (NCDs) to the prohibitive costs of care, particularly in developing countries. The number of people on the planet is set to rise to 9.7 billion in 2050 with 2 billion aged over 60. To cope with this huge demographic shift and build a global healthcare system that is fit for the future, the world needs to address these challenges now.
The global health system will need to adjust to massive population growth, which will be concentrated in the poorest countries, and increasing numbers of elderly. This will mean shifting the current focus on treating sick people towards preventing illness and preserving the health of populations.
