SDG 3: Good Health and Wellbeing
Goal 3: good health and wellbeing
Introduction
Ratified in 2015 by all UN Member States, the 2030 Agenda establishes health as a fundamental human right and a necessity for inclusive, sustainable development (United Nations, 2015). Priorities covering maternal and child health, communicable and non-communicable diseases, mental health, substance use, road safety, universal health coverage (UHC), access to necessary medications and vaccines, and emergency preparedness are all integrated into SDG 3—Ensure healthy lives and promote well-being for all at all ages (UN, n.d.; UNICEF, n.d.). Therefore, progress toward SDG 3 is inextricably linked to equity in access to high-quality services throughout life and to larger social determinants of health. Even though there have been significant advancements in a number of areas since 2015, overall progress obscures enduring disparities within and between nations. While the growing burden of non-communicable diseases and persistent underinvestment in primary health care continue to put strain on health systems, the COVID-19 pandemic revealed systemic weaknesses, interrupted vital services, and exacerbated pre-existing imbalances. These challenges highlight the need for concurrent focus on financial protection, population-level prevention, and service provision in order to achieve SDG 3, backed by solid data and ongoing governance.
Theoretical Background
A fundamental position in the architecture of sustainable development is held by health and well-being. “A state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity” is the World Health Organization’s (WHO) well-known definition of health. This definition expanded post-war understandings beyond biomedical outcomes to include social and psychological domains (World Health Organization [WHO], 1946). SDG 3’s focus on resilience, equity, and life-course health is supported by this holistic viewpoint. According to the SDG framework, well-being is both an intrinsic good and a key factor in human development since it incorporates both subjective and objective elements. These elements range from measurable abilities like the capacity to learn, work, and engage in society to perceived life satisfaction and mental health. The SDG project is anchored by the normative status of health as a human right. The International Covenant on Economic, Social, and Cultural Rights affirms “the right of everyone to the enjoyment of the highest attainable standard of physical and mental health” (UN Committee on Economic, Social, and Cultural Rights [CESCR], 2000), and the Universal Declaration of Human Rights acknowledges “the right to a standard of living adequate for…health and well-being” (United Nations, 1948, art. 25). The AAAQ framework—availability, accessibility, acceptability, and quality—is used by General Comment No. 14 to operationalize this right. It also outlines the state’s obligations to respect, protect, and fulfill this right, including core minimum duties and progressive realization subject to resource constraints (CESCR, 2000). The SDG 3 goals of service coverage, financial security, and secure, high-quality healthcare are closely aligned with these legal concepts. Researchers are using social determinants of health (SDH) to establish a causal link between outcomes, equality, and rights. The WHO Commission on Social Determinants of Health argued that health disparities are “systematically produced” by the unequal distribution of power, money, and resources—materialized through living conditions, education, employment, gender norms, and environmental exposures—building on decades of epidemiological evidence and political economy analysis (Commission on Social Determinants of Health [CSDH], 2008). This literature was summarized by Marmot (2005), who showed that socioeconomic status and morbidity/mortality both within and between countries have graded (or “social gradient”) connections.
SDH frameworks align SDG 3 with cross-cutting goals on poverty (SDG 1), education (SDG 4), gender (SDG 5), decent work (SDG 8), and decreased inequality (SDG 10) by reorienting policy from downstream clinical treatment toward upstream structural levers—tax and transfer policies, early childhood investment, housing, decent work, and environmental quality. Universal health coverage (UHC) serves as the main organizing principle for the realization of SDG 3 in health systems research. All individuals who receive necessary preventative, curative, rehabilitative, palliative, and promotional services of adequate quality while being shielded from financial hardship are considered to be receiving universal health coverage (UHC) (WHO, 2010). Service coverage (effective coverage of essential interventions across reproductive, maternal, newborn, child, infectious, and non-communicable domains) and financial risk protection (incidence of catastrophic and impoverishing health spending) are two composite indices commonly used in monitoring architectures (WHO & World Bank, 2023). Solid primary health care (PHC), skilled and dispersed health workforces, necessary medications and vaccines, dependable supply chains, and solid information systems are prerequisites for universal health coverage (UHC), which goes beyond simple insurance. These skills also support emergency preparedness.
Two historic milestones frame the PHC paradigm: the Alma-Ata Declaration (1978) and the Declaration of Astana (2018). Alma-Ata promoted community-oriented, intersectoral PHC as the means to achieve “Health for All” and affirmed health as a fundamental human right (WHO & UNICEF, 1978). These values were reiterated in Astana forty years later, with a focus on community involvement, integrated services throughout the life course, and people-centered care. PHC was also placed in the context of current issues such emergencies, aging, and non-communicable diseases (NCDs) (WHO & UNICEF, 2018). In line with the Ottawa Charter (1986) on health promotion, which emphasizes positive public policy, supportive environments, community action, personal skills, and reoriented health services (WHO, 1986), these declarations collectively elevate prevention, continuity, and equity as strategic levers for SDG 3.
The epidemiological transition and the double (or triple) burden of disease further shape SDG 3’s theoretical landscape. In addition to chronic infectious diseases, injuries, and rising NCDs (cancer, diabetes, cardiovascular disease, and chronic respiratory disease), many low- and middle-income nations also face mental health issues and substance use disorders that have historically received little attention in international health agendas. Integrated, life-course methods and the significance of effective coverage—rather than just availability—of therapies are validated by this complexity. The economic reason for prevention is also emphasized, as NCDs are linked to intergenerational poverty, fiscal strains, and macro-level productivity losses. These factors support the development case for population health investments. Since COVID-19, health system resilience—the ability to absorb, adapt, and change under shocks—has emerged as a key idea. Resilience necessitates governance structures that promote prompt decision-making, openness, and public trust. It combines robustness (sufficient surge capacity, supplies, and workforce), adaptability (quick reconfiguration of services, such as telemedicine), and transformability (learning and institutional reforms). In order to prevent and manage zoonotic threats and antimicrobial resistance, these characteristics interact with preparedness capacities defined by the International Health Regulations (IHR) and increasingly framed within One Health, which acknowledges the interdependence of human, animal, and environmental health. Lastly, beyond clinical interventions, the health promotion tradition expands the arsenal for well-being. The logic of the Ottawa Charter links macro-level structural conditions with micro-level behavior change by empowering people and communities, creating healthy settings, and coordinating policies across sectors (WHO, 1986). Reflecting SDG-wide requests for integrated governance, this means that policies must be consistent across the following domains in practice: transportation (road safety), education (health literacy), agricultural (nutrition), housing (indoor air quality), labor (occupational safety), and environment (clean air and water). Methodologically, it promotes disaggregation by income, gender, location, disability, and migratory status, as well as mixed-methods, equity-sensitive monitoring, or “leave no one behind.” All things considered, the theoretical underpinnings of SDG 3 are based on four pillars: (1) a normative framework that is rights-based and equity-centered (UDHR; ICESCR/GC14); (2) a causal model that is determinants-oriented and links social and environmental factors to health; (3) a systems paradigm that is operationalized through UHC and PHC and emphasizes quality, financial protection, and resilience; and (4) a promotion and prevention philosophy that incorporates community agency and intersectoral policy. Together, these threads support the scope of SDG 3 and offer standards for assessing advancement and directing changes in the ensuing parts.
Targets and indicators of SDG 3
Sustainable Development Goal 3—Ensure healthy lives and promote well-being for all at all ages—is operationalized through a set of thematically coherent targets (3.1–3.9 and 3.a–3.d) embedded in the UN Global Indicator Framework (A/RES/71/313) and refined by the Inter-Agency and Expert Group on SDG Indicators. With a permanent requirement to separate data by income, sex, age, disability, geography, and other pertinent grounds in order to uphold the Agenda’s equity principle, the framework strikes a balance between outcomes (mortality, morbidity), coverage (access to essential services), risk factors (tobacco, alcohol, pollution), and health-system capacity (workforce, preparedness). (United Nations Statistics Division [UNSD], 2022/2023).
The foundation of SDG 3’s life-course approach is maternal and child survival. In accordance with Target 3.1, nations pledge to keep the global maternal mortality ratio below 70 per 100,000 live births and to make sure that no nation surpasses 140. The percentage of births attended by trained health professionals (3.1.2) and the maternal mortality ratio (Indicator 3.1.1) are used to measure progress, matching an outcome with a proximate service-coverage driver of intrapartum safety (UNSD, 2023a). By promising to eliminate avoidable deaths of children under five, Target 3.2 applies this reasoning to newborns and young children. Specifically, it aims to reduce neonatal mortality to no more than 12 per 1,000 live births and under-five mortality to no more than 25 per 1,000. Monitoring relies on the under-five mortality rate (3.2.1) and neonatal mortality rate (3.2.2), which are among the most mature and widely disaggregated indicators in global health (UNSD, 2023a; UN DESA, n.d.).
The unfinished agenda of communicable diseases is addressed by a supplementary pillar. In addition to fighting hepatitis and other infectious threats, Target 3.3 seeks to eradicate the epidemics of HIV/AIDS, TB, malaria, and neglected tropical diseases. While the number of individuals in need of interventions against neglected tropical diseases (3.3.5) measures the unmet need for preventive chemotherapy and case management across endemic settings, incidence-based indicators monitor the dynamics of transmission for HIV (3.3.1), TB (3.3.2), malaria (3.3.3), and hepatitis B (3.3.4) (UNSD, 2023a). These measures establish a uniform framework for evaluating the efficacy of programs across diverse epidemiological characteristics.
Target 3.4 shifts to non-communicable diseases (NCDs) and mental health in line with the epidemiological trend. According to a combined probability-of-dying indicator, it asks for a one-third decrease in premature mortality from diabetes, cancer, cardiovascular disease, and chronic respiratory illness between the ages of 30 and 70 (3.4.1). Simultaneously, the suicide mortality rate (3.4.2) acknowledges mental health as a factor that determines human potential, production, and social cohesion in addition to being an intrinsic aspect of well-being (UNSD, 2023a). By monitoring treatment coverage for drug use disorders and alcohol consumption per capita—the latter being a well-established risk factor spanning NCDs, injuries, and social harms—Target 3.5 supplements this with system-level responses to substance use (UNSD, 2023a).
Target 3.6, which aims to reduce road traffic fatalities and injuries worldwide by half, specifically addresses injuries. The World Health Organization’s periodic worldwide status reports on road safety are in line with the equivalent, age-standardized road traffic injury fatality rate (3.6.1) (UNSD, 2023a). The percentage of demand for family planning met by contemporary methods (3.7.1) and the adolescent birth rate among females aged 10–14 and 15–19 (3.7.2) are used to track sexual and reproductive health (Target 3.7), capturing both agency-related service coverage and outcomes with intergenerational implications for poverty reduction and education (UNSD, 2023a).
Target 3.8 uses universal health coverage (UHC) as the organizing framework for system performance. The UHC service-coverage index (3.8.1) and financial risk protection (3.8.2), which is determined by the frequency of catastrophic and depressing out-of-pocket medical expenses, are the two complementing dimensions along which monitoring is conducted. With a growing focus on effective rather than merely nominal coverage, the service-coverage index aggregates tracer interventions spanning infectious diseases, NCDs, reproductive, maternal, infant, and child health, as well as service capacity and access. When read together, 3.8.1 and 3.8.2 discourage trade-offs where increased financial hardship is exchanged for increased utilization (WHO, n.d.-a; UNSD, 2023b; WHO & World Bank, 2023).Target 3.9, which attempts to lower mortality and morbidity from hazardous chemicals as well as from pollution and contamination of the air, water, and soil, clearly integrates environmental determinants of health. This is operationalized through three indicators: mortality from unintentional poisoning (3.9.3), mortality from unsafe water, sanitation, and hygiene (3.9.2), and mortality from household and ambient air pollution (3.9.1). Echoing the Agenda’s integrative logic, these measures establish formal links to SDGs pertaining to water and sanitation (SDG 6), renewable energy (SDG 7), sustainable cities and communities (SDG 11), and responsible production and consumption (SDG 12) (UNSD, 2023a).
The “means-of-implementation” targets (3.a–3.d) focus on risk factors, innovation and access, workforce capacity, and preparedness. In accordance with the WHO Framework Convention on Tobacco Control, Target 3.a tracks tobacco control using the age-standardized prevalence of current tobacco use among individuals aged 15 and older (3.a.1) (UNSD, 2023a). Target 3.b addresses the availability and affordability of pharmaceutical and vaccine research and development; its indicators include official development assistance to medical research and basic health sectors as well as metrics of access to essential pharmaceuticals and vaccines, such as routine immunization coverage (UNSD, 2023a). Target 3.c, which acknowledges human resources as a binding limitation on equitable quality care, deals with the density and distribution of health workers (3.c.1), including physicians, nurses, and midwives. Target 3.d, which connects routine system functions with surge readiness in the wake of COVID-19 and other threats, strengthens capacities for early warning, risk reduction, and crisis management. The principal indicator (3.d.1) evaluates International Health Regulations (IHR) core capacities across surveillance, laboratory diagnostics, and response (UNSD, 2023a).
The measuring architecture demonstrates a number of design ideas throughout the target set. In order to provide continuity across age groups and epidemiological hazards, it first takes a life-course view, beginning with maternal and neonatal outcomes and continuing to NCDs and injuries. By mandating disaggregation and associating outcomes with coverage or system-capacity measurements (e.g., maternal mortality with skilled birth attendance; premature NCD mortality with UHC and risk-factor measures), it also embeds fairness. Third, in line with “Health in All Policies” and One Health viewpoints, it incorporates environmental exposures and behaviors—such as air pollution, unsafe WASH, tobacco, and alcohol—into the main health agenda. Fourth, in order to prevent undesirable situations where increases in utilization result in medical impoverishment, it links service coverage to financial protection under UHC (WHO, n.d.-a; UNSD, 2023b). Lastly, it reframes preparedness as a continuous, whole-of-system capability rather than a specialized emergency role by connecting health security to routine system performance through IHR capacities (WHO & World Bank, 2023). In order to facilitate cross-national comparability and ongoing methodological improvement, custodian agencies keep comprehensive metadata that include definitions, preferred data sources, estimating techniques, and warnings for every indicator. As the primary custodian for SDG 3, the World Health Organization coordinates global monitoring reports that summarize progress, pinpoint gaps, and suggest course corrections. It frequently collaborates with UNICEF, UNAIDS, the World Bank, and other organizations to oversee the majority of indicators (UNSD, 2023a; WHO & World Bank, 2023). In practice, this architecture gives decision-makers a logical, policy-relevant prism through which to identify bottlenecks, set investment priorities, and order reforms in the direction of the 2030 health agenda.
Progress and Achievements
Measurable progress has been made in a number of SDG 3 areas since the 2030 Agenda was adopted, however unevenly and with noticeable slowdowns after 2019. The under-five mortality rate decreased to 37 per 1,000 live births in 2022, a decrease of approximately 51% since 2000, and the number of under-five deaths worldwide dropped to a historic low of 4.9 million in 2022 (from 9.9 million in 2000 and 6.0 million in 2015) (UN DESA, 2024; UNICEF/UN IGME, 2024). Although the number of under-five deaths decreased to almost 4.8 million in 2023, according to new UNICEF projections, the U5MR reached 37 per 1,000 in 2023 as well. However, a significant portion of these deaths still occur during the newborn period and are concentrated in South Asia and sub-Saharan Africa (WHO, 2025a). Although progress has slowed since 2015 and pandemic interruptions have increased disparities, these improvements are a reflection of long-term advancements in primary health care, immunization, nutrition, and WASH (UN DESA, 2024; WHO, 2024a).
Long-term declines in maternal health are still noticeable, but they have stabilized in the SDG era. According to the latest inter-agency estimates, there were roughly 260,000 maternal fatalities in 2023, or one death every two minutes. This is about 40% fewer than in 2000, although since 2016, several settings have seen stagnation or reversals in maternal mortality rates (UN MMEIG, 2025). Previous projections for 2020 put the number of maternal fatalities worldwide at over 287,000, highlighting the pandemic’s lasting effects and inequalities (UNFPA/WHO/UNICEF/World Bank/UN DESA, 2023). Regional and national disparities are still glaring: the worldwide maternal mortality ratio has not improved much since 2015 in comparison to the 2030 target, and low- and lower-middle-income countries account for approximately 95% of maternal deaths (UN DESA, 2024).
Trajectories vary for infectious illnesses. Global HIV outcomes have improved: AIDS-related mortality decreased to around 630,000 in 2024, down about 54% since 2010, and new infections (~1.3 million) were about 40% fewer than in 2010 due to the spread of antiretroviral medication to about 31.6 million people (UNAIDS, 2025; WHO, 2025b). However, progress has been unequal, with prevention/treatment gaps still existing among important populations and incidence increasing in some places (UNAIDS, 2024). Although the post-pandemic surge seems to be slowing and may stabilize if diagnosis and treatment gains are sustained, tuberculosis (TB) recovered during COVID-19 interruptions. According to the WHO Global TB Report 2024, 8.2 million newly diagnosed cases occurred in 2023, the highest number since global monitoring began (CIDRAP, 2024; WHO, 2024b; Spotlight, 2024). Next-generation nets and the introduction of malaria vaccines are promising but still in their infancy. Malaria control has maintained many historical gains—the WHO estimates that 2.2 billion cases and 12.7 million deaths have been prevented since 2000. However, in 2023, cases increased to about 263 million and deaths to about 597,000 due to climate shocks, conflict, and drug/insecticide resistance (WHO, 2024c; WHO, 2024d). .
Non-communicable diseases (NCDs) continue to be the leading cause of premature death worldwide; although age-standardized death rates from cardiovascular disease and some types of cancer were lower in many nations prior to 2019, most regions have not made enough progress toward the SDG 3.4 one-third reduction target (WHO, 2024a). Regarding mental health, the age-standardized suicide rate decreased by about 36% worldwide between 2000 and 2019, with different regional trends and only slight further drops until 2021 reported in further WHO updates (Ilić & Živković, 2022; WHO, 2021; IASP, 2025). In many settings, treatment gaps for substance use disorders have also widened in the post-pandemic era. There are two noteworthy system-wide accomplishments. First, according to WHO’s composite index, universal health coverage (UHC) service coverage increased from 45 (2000) to 68 (2021), though gains since 2015 have been modest (+3 points, 2015–2021) and there has been no net improvement since 2019. However, financial protection has not kept pace with coverage progress, and in many countries, catastrophic spending has persisted or gotten worse (WHO, 2025c; WHO & World Bank, 2023). Second, routine immunization is improving after pandemic setbacks: global DTP3 coverage reached about 85% in 2024, and the number of zero-dose children dropped to about 14.3 million, which is still higher than 2019 levels despite regional backsliding in areas of the Americas and areas affected by conflict (WHO, 2025d; PAHO, 2025; Gavi, 2025). These patterns demonstrate the reasoning behind the SDG measurement: equitable access to critical services (e.g., family planning, skilled birth attendance, children immunizations) and financial risk protection (3.8.2) must progress in tandem with coverage increases (3.8.1).
The Sustainable Development Goals Report 2024 presents a sobering overview: as of mid-2024, only 17% of SDG targets were on track, and many health-related indicators showed little progress, with several regressing as a result of pandemic aftershocks, conflict, financial strain, and climate impacts (UNSD, 2024). However, the same dataset highlights tangible levers (primary health care, UHC financing, immunization, and preparedness capacities under the International Health Regulations) that can hasten progress while also documenting historic accomplishments, particularly in child survival and increased access to life-saving technologies. To put it briefly, SDG 3 has unquestionably improved health since 2000 and has maintained significant progress since 2015 despite shocks. To meet the 2030 targets, nations must close persistent equity gaps, regain momentum in maternal health, reverse rising rates of TB and malaria, and combine service expansion with financial protection and resilient, people-centered primary care.
Challenges and Barriers
Since 2019, the world’s progress toward SDG 3 has slowed and, in some cases, reversed. With pandemic-era shocks undermining gains in life expectancy and communicable disease control and exposing severe disparities in access to treatment, the Sustainable Development Goals Report 2024 shows that the world is not on course to meet Goal 3 (United Nations, 2024). Prioritizing universal health coverage (UHC), improved primary healthcare, and targeted investments for vulnerable populations are necessary to change the trajectory (WHO, 2024; WHO, 2025a). Coverage stagnation and financial hardship. Since 2015, service coverage improvements have mainly stagnated, and financial protection has gotten worse—a growing percentage of households face catastrophic out-of-pocket expenses (WHO, 2025a; WHO & World Bank, 2023). Both SDG 3.8 and medical poverty are at risk due to this simultaneous tendency, even in cases where utilization rises (WHO, 2025a).
Maldistribution and shortages in the health workforce. A shortage of approximately 11 million health workers is expected to occur by 2030, with the largest shortages occurring in low- and lower-middle-income nations and inequitably distributed within them; underinvestment in training, retention, and equitable deployment compromises care quality and continuity and impedes the advancement of universal health coverage (WHO, n.d.-a). Communicable-disease setbacks and underfunding. The WHO’s Global Tuberculosis Report 2024 and independent summaries documented record or near-record case notifications as services were halted, indicating that COVID-19 disruptions contributed to a resurgence in tuberculosis (WHO, 2024a; CIDRAP, 2024). Along with climate shocks and resistance, malaria control is facing a growing finance vacuum, with global investments still falling far short of needs (WHO, 2024b). Millions of “zero-dose” children are at danger since routine childhood vaccination rates have not fully recovered to pre-pandemic levels (UNICEF & WHO, 2024). Uneven recovery across regions and brittle program resilience are exposed by these forces (United Nations, 2024).
The NCD and mental-health burden. Despite the fact that many nations decreased age-standardized mortality from major non-communicable illnesses prior to 2019, the rate of reduction is not fast enough to achieve Target 3.4; disparities in prevention and early diagnosis still exist, and gaps in mental health treatment still exist (WHO, 2024). Suicide rates decreased significantly worldwide between 2000 and 2019, with only slight drops continuing into 2021 and varying regional trends (Ilić & Živković, 2022; WHO, 2021).
Climate change and environmental risks. Heat stress, food insecurity, vector-borne disease range shifts, and air pollution morbidity are all made worse by the climate catastrophe, which puts further burden on systems that are already underprepared. Without more aggressive action, WHO projects that malnutrition, malaria, diarrhea, and heat stress will cause an additional 250,000 fatalities per year between 2030 and 2050 (WHO, 2023; WHO, n.d.-b).
Preparedness gaps and health security. Countries have varying IHR capabilities for rapid response, laboratories, and surveillance, notwithstanding the lessons learned from COVID-19. Although many systems lack dependable surge capacity and risk communication, WHO’s Joint External Evaluation, 3rd ed. emphasizes preparedness as a continuous, whole-of-system capability embedded in routine care; the most severe constraints are found in fragile and conflict-affected settings (WHO, 2025b; WHO EMRO, n.d.). Antimicrobial resistance (AMR). The efficacy of regular care across SDG 3 targets is threatened by AMR. With GLASS showing widespread resistance and insufficient monitoring in many countries, WHO attributes 1.27 million deaths in 2019 directly to bacterial AMR (4.95 million associated). AMR will increase mortality and costs, undermining UHC and emergency readiness, unless accelerated stewardship, access to affordable, effective antibiotics, and infection-prevention measures are implemented (WHO, 2023b; WHO, n.d.-c; Naghavi et al., 2024).
Equity and data limitations. Large within-country disparities by location, income, gender, handicap, and displacement are obscured by national averages. The “leave no one behind” pledge has been hampered in low-income and crisis-affected areas, where service coverage recovery has been delayed, and data systems also have difficulty providing timely, disaggregated indications for focused action (United Nations, 2024).
A mutually reinforcing barrier system is created by these limitations taken together: stagnant coverage with increasing financial risk, personnel shortages, budget gaps and communicable disease rebounds, NCD headwinds, climate-amplified risks, readiness shortfalls, AMR, and enduring imbalances. AMR stewardship and access initiatives, climate-smart health systems, sustained investment in primary health care and workforces, financing and governance to expand effective coverage with financial protection, strengthened IHR-aligned preparedness, and equity-focused measurement to target interventions where needs are greatest are all necessary to meet SDG 3 by 2030 (WHO, 2024; WHO, 2025a; WHO, 2025b).
Policy Frameworks and Global Governance
SDG 3’s governance architecture is multi-level and polycentric, incorporating platforms for funding and coordination, political declarations and compacts, and legally binding instruments. With its constitutional mandate and programmatic guidelines, the World Health Organization (WHO) is at the center. Member States establish standards through the International Health Regulations (IHR 2005), a legally binding framework that outlines rights and obligations for surveillance, notification, and public health response to events of global concern (WHO, 2016). WHO’s Joint External Evaluation (JEE) tool, which was most recently updated to improve evaluation of legal instruments, financing, and health-emergency management, supports operationalization and peer learning by highlighting preparedness as a whole-of-system capability rather than a specific emergency function (WHO, 2022). WHO’s medium-term strategy—the Fourteenth General Programme of Work (GPW 14), 2025–2028—aligns organizational priorities with the SDGs, emphasizing primary health care (PHC), universal health coverage (UHC), health security, and cross-sectoral action on determinants (WHO, 2024a).
Beyond core regulations, global tobacco control illustrates how treaties advance SDG 3 risk-reduction. The WHO Framework Convention on Tobacco Control (FCTC)—the first global public-health treaty—has near-universal participation and codifies evidence-based measures on taxation, smoke-free environments, advertising bans, packaging, and illicit trade, with governance through the Conference of the Parties and the Protocol to Eliminate Illicit Trade in Tobacco Products (WHO FCTC Secretariat, 2021; WHO FCTC Secretariat, 2025). On access to medicines, the Doha Declaration on the TRIPS Agreement and Public Health clarifies WTO flexibilities (compulsory licensing, parallel importation) to protect public health and promote access for all—an enduring legal pillar for SDG 3.b that interacts with national procurement and industrial policies (WTO, 2001).
The UN General Assembly High-Level Meetings (HLMs) have frequently boosted UHC at the political level. Primary health care is reaffirmed as the foundation of resilient systems in the 2019 and 2023 Political Declarations on UHC. Member States are also committed to strengthening workforces, investing in readiness, and expanding critical services and financial protection (UNGA, 2019; UNGA, 2023). Through UHC2030, whose Global Compact for Progress towards UHC unites governments, international organizations, civil society, and the business sector around values including accountability, transparency, and equity, partners work together to put commitments into action (UHC2030, 2017; UHC2030, n.d.). The Global Action Plan for Healthy Lives and Well-being for All (SDG3 GAP), which was started by 13 agencies and is now complete, aims to better align donors with national plans. Its 2024 progress report emphasizes the need for lower transaction costs and more robust country-led coordination (WHO, 2024b; WHO, 2025b).
The Pandemic Fund, a World Bank Financial Intermediary Fund that offers grants to strengthen core capacities (surveillance, laboratories, workforce, and community engagement) with an emphasis on low- and middle-income countries, has increased financing and collective action on pandemic prevention, preparedness, and response (PPR). Recent replenishments have scaled available resources, but needs are still far greater than current commitments (World Bank, n.d.; The Pandemic Fund, n.d.; Reuters, 2024). These tools support the mobilization of domestic resources and are consistent with the funding principles of the Addis Ababa Action Agenda that are often cited in UHC compacts (UHC2030, 2017). Together, these frameworks form a normative-institutional stack for SDG 3: the Pandemic Fund and country-aligned partner platforms (e.g., SDG3 GAP lessons) address coordination and resourcing; GPW 14 establishes WHO’s strategic backbone; UHC Political Declarations and the UHC2030 Compact articulate political commitments and partnership norms; and IHR and FCTC provide binding global rules. Using JEE and IHR capabilities to drive continuous improvement, integrating treaty obligations into domestic law and budgets, tying UHC service-coverage expansion to financial protection, implementing TRIPS flexibilities where necessary to protect access, and making sure external finance and partner support are in line with national PHC-led strategies are all essential components of effective governance at the national level. Therefore, improving implementation, accountability, and coherence within this current governance ecosystem is more important to the SDG 3 agenda than creating new tools.
Future Outlook, Conclusion and Recommendations
SDG 3’s overall trajectory is off course with less than ten years to go, but if nations step up their efforts in primary health care, universal health coverage (UHC), and preparation, there is a clear window to regain momentum (United Nations, 2024; WHO, 2024a; WHO & World Bank, 2023). Results will be shaped by a number of factors until 2030. First, in many low- and middle-income countries, demographic and epidemiological changes continue to increase the “double/triple burden”: growing non-communicable diseases (NCDs) and injuries coexist with incomplete communicable-disease agendas. Gains will require rebalancing investment toward prevention and early detection, provided by robust PHC, while maintaining financial protection, given the scope and speed of change (WHO, 2024a; WHO & World Bank, 2023). Second, vulnerable communities will be disproportionately affected by health shocks brought on by climate change and environmental hazards, which will increase everything from heat stress and malnutrition to changes in the range of vector-borne diseases and air pollution. WHO estimates that between 2030 and 2050, an additional ~250,000 fatalities per year will result from climate-sensitive causes if stronger action is not taken. This emphasizes the necessity of low-carbon, climate-resilient health systems and cross-sector policy coherence (WHO, 2023a). Third, it is necessary to view health security as a system-wide capacity. The International Health Regulations (IHR) monitoring and the updated Joint External Evaluation (JEE, 3rd ed.) place a strong emphasis on the ongoing enhancement of basic capabilities—risk communication, laboratories, and surveillance—integrated with regular service delivery (WHO, 2025a). In low-resource settings, new finance tools like the Pandemic Fund can fill gaps, but consistent domestic investment and adherence to national plans are still crucial (Reuters, 2024; World Bank, n.d.). Fourth, by compromising emergency response and routine treatment, antimicrobial resistance (AMR) poses a threat to erode progress made toward SDG 3. According to recent estimates, bacterial AMR was directly responsible for 1.27 million fatalities in 2019 (with an additional 4.95 million deaths linked to it). This highlights the importance of infection prevention, surveillance, stewardship, and availability to reasonably priced, effective antibiotics (Naghavi et al., 2024; WHO, 2023b).
Lastly, digital change is an encouraging but inequitable facilitator. While highlighting prospects such as telemedicine, decision assistance, and supply-chain visibility, WHO’s global strategy on digital health warns that gains won’t be realized until digital investments are rooted in PHC, equity, governance, and data protection (WHO, 2021; WHO & UNICEF, 2020).
The data presented in the previous sections is alarming: coverage has stagnated since 2015, financial hardship is increasing, and readiness gaps still exist despite unprecedented gains in child survival and increases in critical services (United Nations, 2024; WHO & World Bank, 2023). Additionally, progress is unequal; there are still significant differences within countries based on factors including income, gender, geography, disability, and displacement. However, the policy playbook is well-known and reasonably priced. Investing in PHC-led UHC, shielding households from out-of-pocket shocks, and developing IHR-aligned emergency capacities helped these nations weather recent crises better and recover more quickly (WHO, 2024a; WHO, 2025a). Therefore, the road to 2030 is less about creating new tools and more about putting them into practice at scale: assessing successful coverage and equity; bringing data and decisions closer together; and coordinating legislation, budgets, and partner assistance with national goals. Recommendations:
- Re-center primary health care (PHC) as the delivery backbone. Implement the WHO/UNICEF PHC Operational Framework to integrate promotive, preventive, curative, rehabilitative, and palliative services across the life course; prioritize team-based care, referral continuity, community engagement, and essential public-health functions (WHO & UNICEF, 2020; WHO, 2018).
- Finance UHC for both service coverage and financial protection. Track and manage the UHC pair—service coverage (SDG 3.8.1) and catastrophic/impoverishing spending (3.8.2)—to avoid expansions that increase medical poverty. Use benefit-package revision, strategic purchasing, and exemption policies to protect the poor (WHO & World Bank, 2023).
- Close the health-workforce gap. Fund pre-service education, equitable deployment, and retention (including rural pipelines and task-sharing); strengthen regulation, decent work conditions, and continuous professional development to improve quality and resilience (WHO, n.d.-a).
- Accelerate high-value prevention for NCDs and mental health. Scale WHO “best buys” (tobacco and alcohol taxation and marketing restrictions; salt reduction; hypertension and secondary prevention for CVD; HPV/cervical cancer control) alongside mental-health integration in PHC and suicide-prevention packages (WHO, 2017; WHO, 2024a).
- Recover and expand immunization. Reach “zero-dose” and under-immunized children through PHC micro-planning, outreach, and data-use; sustain new vaccine introductions (e.g., malaria vaccines where indicated) with attention to deliver quality and community trust (United Nations, 2024; WHO, 2024a).
- Strengthen communicable-disease control and end-epidemic pathways. Restore TB and HIV testing/treatment to pre-pandemic trajectories; deploy vector control and next-generation tools for malaria; expand hepatitis B birth-dose and treatment cascades, guided by national epidemiology (WHO, 2024a).
- Build climate-resilient, low-carbon health systems. Climate-proof health facilities (cooling/ventilation, flood/heat plans), secure water/energy supply, protect supply chains, and integrate early-warning information; prioritize clean energy and sustainable procurement to reduce the sector’s footprint (WHO, 2023a).
- Institutionalize preparedness under IHR. Use JEE findings to create financed, time-bound capacity-building plans; conduct after-action reviews and simulation exercises; expand genomic and wastewater surveillance; and link preparedness to PHC surge plans (WHO, 2025a).
- Confront AMR with a “one-two” strategy: stewardship + access. Enforce prescription and dispensing regulations; expand infection prevention and control; ensure reliable access to quality-assured antibiotics and diagnostics; and strengthen GLASS participation and data use (WHO, 2023b; Naghavi et al., 2024).
- Make digital health work for equity. Invest in connectivity for frontline facilities, interoperable registries, and decision-support tools tied to PHC workflows; adopt governance for privacy, cybersecurity, and algorithmic accountability; and evaluate impact on effective coverage, not just adoption (WHO, 2021).
- Measure what matters—disaggregate and use data. Embed routine disaggregation (income, sex, age, disability, geography, migration) across SDG 3 indicators; link monitoring to accountability (budget/program review), with community participation (United Nations, 2024).
- Align external finance with country plans. Use UHC2030 principles and the Pandemic Fund to coordinate partners around nationally prioritized capacity gaps; reduce transaction costs and ensure domestic co-financing and sustainability (UHC2030, 2017; Reuters, 2024; World Bank, n.d.).
These suggestions are not new; rather, they represent a logical, fact-based strategy to help SDG 3 achieve its 2030 goal. The key element is the financial and political will to put them into practice—continuously, fairly, and widely—so that health may serve as a human right and the catalyst for sustainable development.
