Chapter 2: global Health priorities and achievements

Identify and discuss the major global health achievements over the past century, emphasizing innovations in health technology and their impacts. Address the disparities in access to these innovations and explore how they have contributed to health disparities globally. Describe strategies used for prioritizing global health issues, including the concept of disease burden, cost-effective interventions ("best buys"), and the importance of expertise in funding and implementing health programs. Explain framing tools such as health metrics, vital statistics, life expectancy, and measures of morbidity like YLLs, YLDs, and DALYs that guide health policy decisions. Examine the role of international initiatives such as the Millennium Development Goals (MDGs) and the Sustainable Development Goals (SDGs), highlighting their objectives, successes, and challenges in promoting health equity and sustainable development. Provide insights into how global health security, globalization, and health transitions influence current and future health priorities.

Over the past century, global health has experienced remarkable achievements driven by technological innovations and targeted interventions that have substantially reduced morbidity and mortality worldwide. The advent of vaccines, antibiotics, and advanced diagnostics has transformed disease management, leading to declines in infectious diseases and improved life expectancy. For example, immunization campaigns have eradicated smallpox and dramatically reduced polio cases, showcasing how technological progress can triumph over once-devastating diseases (Swansburg et al., 2017). These health innovations have contributed to life expectancy increases globally, highlighting durable progress in public health outcomes.

Nevertheless, access to these advancements is uneven across regions, amplifying existing health disparities. High-income countries often benefit from early and widespread access to health technologies, while low- and middle-income countries face infrastructural, financial, and political barriers, resulting in persistent inequalities (Marmot, 2015). These disparities underscore the critical need for global health strategies that bridge access gaps, ensuring equitable distribution of innovations and healthcare resources to all populations.

Efficient prioritization of global health issues is essential for maximizing impact, especially given limited resources. Strategies such as assessing disease burden—measured through health metrics like mortality rates, DALYs, and the economic impact—help identify health challenges that most significantly affect populations. For example, the burden of communicable diseases like HIV/AIDS, malaria, and tuberculosis has historically guided global health initiatives (WHO, 2019). Interventions are prioritized based on their cost-effectiveness, with "best buys"—such as primary prevention measures like vaccination and vector control—being highly prioritized due to their efficacy and affordability (Pathways to Global Health, 2008).

Expertise in particular health domains also enhances impact, as agencies leverage their specialized knowledge for program implementation. Initiatives like the Grand Challenges in Global Health exemplify how scientific and technological expertise can guide innovative solutions (Varmus et al., 2003). Additionally, equity-focused groups prioritize interventions that mitigate health disparities, while security-focused strategies address threats to global stability posed by pandemics and emerging infectious diseases (Koplan & Fleming, 2000). Such multifaceted approaches ensure that global health priorities encompass a range of socio-political and economic factors.

Health metrics provide crucial evidence to inform policy decisions. Vital statistics, such as birth and death rates, offer baseline data on population health. Life expectancy at birth and healthy life expectancy (HALE) serve as key indicators of overall well-being and the success of health systems (WHO, 2016). Morbidity measures—including incidence, prevalence, YLLs, YLDs, and DALYs—quantify the burden of diseases, accounting for both fatal and non-fatal health outcomes. For instance, DALYs combine years lost due to premature death with years lived with disability, offering a comprehensive view of health losses (Murray & Lopez, 2016). These metrics guide resource allocation by highlighting priority areas, such as chronic diseases or infectious outbreaks.

Global initiatives like the Millennium Development Goals (MDGs) and the Sustainable Development Goals (SDGs) have been instrumental in setting measurable targets for health improvement. The MDGs (2000–2015) focused on reducing child mortality, improving maternal health, combating HIV/AIDS, and eradicating extreme poverty, leading to significant progress in many of these areas (UN, 2015). The SDGs, launched in 2015, broaden the focus to include health as integrated into a broader framework of sustainable development. SDG 3 aims to "ensure healthy lives and promote well-being for all," covering a wide spectrum of targets—from combating emerging diseases to universal health coverage—reflecting an evolved approach that addresses social determinants of health and health equity (WHO, 2019).

In addition, global health security—defined as protecting populations from health threats—has become increasingly prominent amid emerging infectious diseases, bioterrorism, and pandemics. Coordinated efforts involving governments, international organizations, and military agencies aim to build resilient health systems capable of rapid response (Katz et al., 2017). Globalization further amplifies health challenges and opportunities, facilitating rapid disease spread but also enabling swift collaborative responses. As the world continues to evolve, health transitions—shifts from infectious to chronic diseases as dominant health burdens—necessitate adaptive strategies that address changing epidemiological patterns (Omran, 1971). Together, these complex factors shape the future of global health priorities, emphasizing the importance of collaboration, innovation, and equitable access.
