More than half of the world’s population still lacks access to essential health services, while billions of people face financial hardship when they need medical treatment, according to the World Health Organization.
The warning comes as the WHO launches its 2026 Universal Health Coverage campaign, putting renewed pressure on governments to expand access to healthcare while protecting households from unaffordable medical costs.
The WHO says more than 2.1 billion people face financial hardship because of healthcare payments made directly from their own pockets.
For millions of families, seeking medical treatment can therefore create a second crisis alongside the health problem itself.
A hospital visit, prescription, diagnostic test or specialist consultation can mean cutting spending on food, education, housing or other basic needs.
The figures highlight a central contradiction in global healthcare. Medical technology and treatment options have expanded dramatically, yet access to those advances remains deeply unequal.
Healthcare Remains Out of Reach for Billions
Universal health coverage is based on the principle that people should be able to receive the healthcare they need without being pushed into financial hardship.
That includes preventive services, diagnosis, treatment, rehabilitation, medicines and other essential forms of care.
The WHO says the world remains significantly behind that objective.
Its latest global monitoring data estimates that 4.6 billion people lacked coverage for essential health services in 2023.
At the same time, 2.1 billion people experienced financial hardship because of out of pocket health spending in 2022.
The figures show that access to healthcare is not simply a question of whether hospitals or doctors exist.
A health system may have hospitals, medicines and trained professionals while still leaving large sections of the population unable to afford treatment.
The Poor Carry the Heaviest Burden
Healthcare costs do not affect all households equally.
For wealthy families, an unexpected medical bill may be financially uncomfortable but manageable. For households already living close to the poverty line, even a relatively modest healthcare payment can consume money needed for food, rent or education.
The WHO says financial hardship caused by healthcare spending remains highly unequal.
Among the poorest populations, roughly three out of four people face financial hardship from healthcare costs, compared with around one in 25 among the wealthiest populations.
That gap illustrates why universal health coverage is increasingly being treated as both a health issue and an economic issue.
When families cannot afford treatment, illnesses can become more serious.
When families borrow money or sell assets to pay for treatment, healthcare can deepen poverty.
When people avoid medical care because they cannot afford it, preventable conditions can become emergencies.
The consequences can therefore extend far beyond the hospital.
The Hidden Cost of Paying for Healthcare
Out of pocket payments are one of the most significant barriers to financial protection.
Under this model, patients pay directly when they receive treatment rather than relying primarily on pooled public financing or insurance systems.
The WHO says financial protection is a core component of universal health coverage because healthcare payments should not prevent households from meeting their basic needs.
The organisation estimates that 1.6 billion people were pushed into poverty or pushed further into poverty by direct healthcare costs in 2022.
That means the impact of healthcare spending cannot be measured only by hospital bills.
It can also be measured by families losing economic security.
A parent may postpone treatment because the household cannot afford it. A worker may continue working while sick because missing income would make medical care unaffordable. A family may borrow money to pay for an emergency and spend years repaying the debt.
These effects are often invisible in conventional health statistics.
Healthcare Inequality Is Also an Economic Problem
The global debate around healthcare often focuses on hospitals, doctors, medicines and technology.
But financing is equally important.
If people cannot afford to use the health system, expanding the number of facilities alone will not solve the problem.
Governments therefore face pressure to increase public financing, strengthen pooled funding systems and reduce dependence on direct payments by patients.
The WHO argues that prepaid and pooled financing mechanisms can provide stronger financial protection because the cost of healthcare is distributed across larger populations rather than concentrated on individuals when they become ill.
This becomes particularly important during economic crises.
Inflation, unemployment and rising living costs can reduce household capacity to absorb unexpected medical expenses.
A health system that depends heavily on patients paying at the point of care can therefore become increasingly difficult to access when families are already under economic pressure.
The Global Health Gap Is Not Just About Poor Countries
Healthcare inequality is often presented as a problem limited to the world’s poorest countries.
The reality is more complicated.
Different countries face different levels of healthcare access and financial protection, but the underlying problem can occur across income groups.
Even in countries with advanced hospitals and sophisticated medical systems, people can delay treatment because of cost, struggle with prescription expenses or face financial pressure from major illnesses.
The global figures therefore reflect a broader challenge.
Healthcare systems can be technologically advanced while still failing to provide adequate financial protection.
The question is not simply whether treatment exists.
The question is whether people can actually reach it and afford it when they need it.
Governments Face Pressure to Act
The WHO’s 2026 campaign is calling on governments to remove barriers to care and accelerate progress toward universal health coverage.
The organisation says governments need to meet people’s health needs while protecting them from unaffordable healthcare costs.
That requires more than emergency programmes.
It involves building sustainable systems capable of providing primary care, medicines, preventive services and treatment without placing excessive financial responsibility on individual households.
Primary healthcare is particularly important because early diagnosis and treatment can prevent conditions from becoming more expensive and complicated.
When people delay care because of cost, the eventual medical intervention can be more difficult and more expensive.
The 2030 Deadline Is Approaching
Universal health coverage is part of the United Nations Sustainable Development Goals, with 2030 established as the target year for achieving major global development objectives.
The WHO’s latest monitoring report warns that progress toward universal health coverage has slowed and that current efforts are not sufficient to reach the global goals without faster action.
The organisation estimates that 4.6 billion people lacked essential health service coverage in 2023.
The remaining gap is therefore enormous.
The challenge is particularly serious because health systems are simultaneously dealing with conflict, displacement, climate pressures, demographic changes, economic instability and shortages of healthcare workers.
Countries facing these pressures must decide how to allocate limited resources while protecting vulnerable populations.
Healthcare or Financial Survival
For billions of people, the issue is ultimately straightforward.
When someone becomes sick, they need to know that seeking treatment will not threaten their ability to pay for food, housing or education.
That principle is at the centre of universal health coverage.
The latest WHO figures show how far the world remains from achieving it.
More than 4.6 billion people lack essential health service coverage, while 2.1 billion people face financial hardship from healthcare spending.
Behind those figures are households making difficult choices between treatment and other basic necessities.
The global healthcare debate is therefore no longer only about building hospitals or developing new medicines.
It is about who gets access to those advances and who is forced to pay the highest price for being sick.
As the WHO launches its 2026 campaign, governments face a widening gap between the promise of healthcare for everyone and the financial reality experienced by billions of people.
Closing that gap will require sustained public investment, stronger health systems and financing structures that treat healthcare as a basic need rather than a financial burden that falls hardest on those least able to carry it.
