- More than 4.6 billion people still lack access to essential healthcare, highlighting how progress toward Universal Health Coverage has slowed despite earlier global gains.
- The biggest challenges now include rising noncommunicable diseases, limited rehabilitation and palliative care, healthcare worker shortages, and inadequate financial protection, putting the 2030 UHC goal at risk.
Envision a commitment extended to everyone around the globe: when you fall ill, you have access to a physician. When you are expecting a child, you can give birth securely. When you are facing the end of life, you will not endure suffering. That none of this will lead to financial ruin for your family. This commitment is known as Universal Health Coverage, or UHC, and by 2026, the world is lagging in achieving it.
Based on the latest global health data from the World Health Organization, approximately 4.6 billion individuals more than half of the world’s population still do not have complete access to necessary health services. The universal health coverage (UHC) service coverage index, which gauges how effectively countries provide care, increased from 68 to 71 between 2015 and 2023. While that may seem like a step forward, it pales in comparison to previous progress: in the fifteen years prior, the same index rose from 54 to 68. Although advancements continue, they have slowed significantly, coinciding with a time when the world can least afford such a deceleration.
It would be helpful for understanding the stakes involved to look at the idea of universal health coverage in light of the five major pillars that underlie UHC: prevention, treatment, rehabilitation, palliation, and financial protection. All of them are currently facing challenges, but in unique way.
What Universal Health Coverage Actually Means
Universal Health Coverage is not a specific program or policy. It is a goal in which people all over the globe receive all the necessary healthcare services, including prevention, treatment, rehabilitation, and palliative care, without falling into poverty due to paying for these services. According to the World Health Organization, UHC is a process during which an individual receives these healthcare services while at the same time having financial protection from losing his/her house, life savings, or money for his/her kid’s education.
All countries should determine their own way to reach this aim based on their available resources. However, the aim itself is the same, but today most of the world population is far from it.
Preventive Care: Where the Gains Are Real — and Where They’ve Stalled
The victories are real. New HIV infections decreased by 40 percent from 2010 through 2024. Cases of neglected tropical diseases needing intervention have been reduced by 36 percent in the same time frame. Smoking and alcohol consumption have gone down since 2010. Under five mortality rates have halved since 2000.
However, upon digging deeper to discover the reasons for the improvements, a trend becomes clear. Almost 51 percent of the global rise in access to healthcare since 2000 has been due solely to efforts to control infectious diseases. Efforts to vaccinate and treat HIV infections, alongside neglected tropical diseases, have driven much of the progress. At the same time, preventive and care services for reproductive, maternal, newborn, and child health has stagnated in recent years. Immunization rates among children remain below the mark worldwide, and it has opened the door for disease outbreaks. The uncomfortable truth is that the world got good at preventing a specific category of illness — infectious disease — while prevention efforts for everything else, from maternal complications to chronic conditions, quietly stagnated.
Curative Care: The Rise of Diseases the System Isn’t Built For
While prevention may have its Achilles heel, curative medicine certainly has its own – the very same noncommunicable diseases (NCDs): heart disease, diabetes, cancer, chronic respiratory disease.
The share of fatalities attributed to such illnesses has grown to predominate globally but the index measuring the availability and quality of curative care services to those affected remains the lowest among all indices tracked by WHO at 61 points, as of 2023. The efforts to decrease premature deaths due to NCDs have stalled considerably since 2015, despite growing prevalence of such conditions associated with aging and changing diets across the globe.
And this is an institutional mismatch. Many health care systems of various nations were designed and funded with the response to infectious diseases in mind – vaccination, antibiotics, outbreak containment. Treating chronic illnesses is a fundamentally different process – building long-term patient-provider relationships, managing drugs, conducting routine monitoring and accessing specialists that most healthcare infrastructures, particularly of poorer countries, cannot offer. Defeating an infection is a sprint while dealing with a chronic condition is a marathon and most global healthcare systems are geared towards sprinting.
Rehabilitative Care: The Quietest Gap in the System
Among the five pillars, the rehabilitative care pillar receives the least attention and perhaps also presents the most challenging path. This includes all physical rehabilitation post-stroke or injury, all types of prosthetic assistance, and psychological support that enables the person to resume their normal lifestyle post-illness.
While the need for rehabilitation does not garner the same amount of media attention as vaccines and hospitals, it has a multiplier effect as well as no rehabilitation means that a curable injury turns into a lifelong disability and that an illness turns out to be a life without earnings and independence. With noncommunicable diseases and injuries claiming a larger proportion of the world’s burden of diseases, the demand for rehabilitation care services is increasing much faster than the ability of many countries to meet the needs – especially for those residing in rural and poorer populations where such services are not widely available.
Palliative Care: Dying Without Dignity
Palliative care, which is the provision of services to alleviate the pain and suffering of individuals with severe illnesses or near death, is one of the most invisible elements of the UHC agenda, since progress in this sector is not about survival rates but rather whether an individual suffers unnecessarily during his or her last months.
Provision of palliative care, including access to pain-relieving medicines, continues to be very uneven globally. In developing countries, the use of opioids, which is common practice in developed countries, is limited or totally absent because of either legal or logistical barriers or shortage of skilled staff. With the aging of the global population and growing importance of noncommunicable diseases, the number of people who would require palliative care annually is going to grow further. However, this aspect of healthcare is still one of the least funded and prioritized aspects of the UHC agenda in discussions of global health financing.
Why 2026 Is a Particularly Fragile Moment
There are two trends which are converging today making the stall particularly perilous. First, international support for global health programs has been scaled down in many donor countries, reducing budgets precisely when health care systems depend heavily on foreign aid. Secondly, the world is experiencing increasing shortages of health care workers – there are simply not enough doctors, nurses and community health workers to provide the services funded.
Considering already existing long-term factors mentioned above – aging of the population, increase in the share of noncommunicable diseases, the health risks related to climatic changes – 2026 will appear less like an interim dip and more like a turning point. Given that the current trend persists, the level of the global service coverage index is forecasted to be 74 by 2030, while about one-fourth of the world population will continue to face the catastrophic level of health expenditures.
The Bottom Line
Universal Health Coverage could never have been an easy task. The narrative from the past decade has been that it was never an unrealistic goal, but rather a narrative about significant progress that helped build momentum, which later faded away. The infrastructure that helped to achieve early successes, which mainly concerned infectious diseases, did not have the capacity to handle the coming challenges related to chronic diseases, aging, rehabilitation, dignified dying, and most importantly financial protection.
To bridge the gap between the infrastructure used in the past decade and the new challenges, the world will need something similar to that which created the problem – strong political will, converted into funds invested in primary care, and healthcare services provided without taking into account the specific conditions.
In other words, the world has already proven that it can work on the issue. The problem is – does it have the will to continue?
