Miracles have happened in global health over the last
fifteen years. Deaths from malaria and tuberculosis have each fallen by a
quarter or more globally. Twelve million people in sub-Saharan Africa with
HIV/AIDS were put on lifesaving treatment.
The great killers of children – pneumonia, diarrhoeal
diseases, measles, whooping cough, and diphtheria—are receding. The once
fearsome scourges of polio and Guinea worm are on the verge
of extinction.
While the war against microbes is hardly over, the
need for continued vigilance should not blind us to the great progress that has
occurred. For the first time in recorded history, plagues, parasites, and other
infectious diseases are no longer the leading causes of years of life lost to
death and disability in any region of the world.
In 1950, one out of five children perished before their
fifth birthday in nearly one hundred countries, including almost every nation
in sub-Saharan Africa, South Asia, and Southeast Asia. Today, the number of
countries where one out of five children die under the age of five is zero. The
average baby born in a developing country is now expected to live to 70.
But the sustainability of this era of miracles in
global health is uncertain. The recent gains in longevity and child
survival in many countries have not been accompanied by the same economic
growth, job opportunities, and infrastructure improvements that occurred with
those changes in today’s wealthy nations.
While extreme poverty has declined everywhere, the middle
class has hardly expanded at all in South Asia and Africa. When higher-income
countries took on the scourge of infectious diseases, advanced medicines played
less of a role than today.
Only half of the declines in death rates in developing
nations between World War II and 1970 were due to vaccines and antibiotics.
Instead, the drivers of public health progress were government measures like
quarantines and housing reform, investments in effective water and sewage
systems, and improvements in girls’ education and child care.
China was poorer than Chad, Benin, or Niger when it began a
dramatic campaign against plagues and parasites after World War II that helped
it later emerge as one of the great global economic powers.
In contrast, medical innovations and global health aid
initiatives are driving more of the recent progress against infectious
diseases.
Beginning in 2002, global health aid to reduce child deaths,
maternal mortality, and the infectious diseases in poor countries rose more
than 10 percent annually over a decade, expanding from £8.25 billion to £21.6
billion.
From shantytown slums in sub-Saharan Africa to the rural
highlands of Peru, aid-funded programs brought medicines, vaccines, and
insecticide bed-nets to world’s poorest people.
The returns on those investments are spectacular and
measured in longer lives and the reduced suffering of children, but broader
economic and social benefits of improved health have remained elusive. While
extreme poverty has declined everywhere, the middle class, individuals living
on $10 to $20 per day, has hardly expanded at all in South Asia and Africa, the
places that have recently seen the greatest health improvements.
With limited access to health care and many people still too
poor to purchase it out of pocket, cases of cancers, diabetes, and heart
diseases are surging in many lower-income countries.
When low-income nations finally achieved an average life
expectancy of 60 in 2011, their median GDP per capita (£815) was a quarter of
the wealth that the residents of high-income countries possessed when they
reached that same average life expectancy in 1947 (£3371).
In too many countries, too little is being done to ensure
that the children and infants surviving to adulthood find adequate health
systems and employment opportunities to accommodate their needs as adults. The
governments of all 48 countries of sub-Saharan Africa spend less on health care
than the government of Australia.
With limited access to health care and many people still too
poor to purchase it out of pocket, cases of cancers, diabetes, and heart
diseases are surging in many lower-income countries. Foreign aid to address
these non-communicable diseases has been lacking. The disparity in adult health
–life expectancy at age 15 – between wealthy and poor nations is growing, even
when one ignores the effects of HIV/AIDS.
More people surviving childhood and adolescence used to mean
more workers for factories and mills. But manufacturing only employs 7 percent
of the workforce in sub-Saharan Africa, and manufacturing represents the same
share of overall economic output in that region as it has since the 1960s.
The World Bank estimates that the working-age population (more
than 15 years old) in developing countries will increase by 2.1 billion by
2050. Unless current national employment rates improve, that will mean nearly
900 million more young adults without work.
The recent declines in infectious diseases present an
historic but time-limited opportunity. With steeply rising rates of child
survival, more sub-Saharan Africans will reach the ages of prime employment
(ages 15 to 64) by 2035 than will be added by the rest of the world combined.
While sub-Saharan Africa has greatly increased school
attendance, up to 40 percent of children in the region still do not meet basic
learning outcomes in numeracy, and half fall short in literacy. Without more
investment in quality education, capable health care systems, and workforce
development, large numbers of underemployed and under-productive young adults
can be a recipe for instability and higher rates of migration.
Providing greater health access and more efficient health
care delivery, especially for vulnerable populations, are priorities for anyone
involved in public health. Poor health systems in developing countries mean a
shortage of trained health care workers, inconsistent inventory of medical
supplies, and inadequate surveillance systems. This list is not exhaustive, but
we can start here. Building a better health infrastructure, like
many public health priorities, requires multi-level coordination.
Empowerment has to spread out from the government to the community and to the
individual.
We can address the problem first by tackling the shortage of health care workers. Doctors in developing countries are in critically short supply. In 2006, the World Health Organization compiled data on the impact of HIV/AIDS on the health workforce in developing countries. Results showed that while European and North American countries have doctors at a ratio of 160 to 560 per 100,000 people, African countries only have two to sixty doctors for every 100,000. In Malawi, for example, there is one doctor for every 50,000 people.

In Malawi, for example, there is one doctor for every 50,000 people.
The global shortage of trained hospital and health care
staff currently exceeds four million. Training more staff and volunteers is one
solution for improving health systems in developing countries. Training other
previously unqualified individuals could ameliorate these shortages. Providing
incentives for already trained workers to stay in a vulnerable state or country
could help build a struggling health system. Having a foundation of trained
workers and preventing them from migrating to wealthier countries is an
important first step. Empowerment and opportunities to grow and help are at the
heart of this strategy.
The second hurdle is maintaining a constant inventory of
equipment, medicines, and other health supplies. War, along with political and
social unrest, in certain regions further dampens the efforts to provide a
steady supply chain. There has to be cooperation between donors and the
government to work with the private sector to ensure receipt of necessary
health supplies. Partnering with emerging pharmacy chains increases the
availability of medicines and drives down the cost for the patients. In the
Philippines, Generics Pharmacy has thousands of small storefronts that are
widely used by both the rich and poor.
Convenience and ease of access are often of paramount
interest to every person, regardless of income. The issue of payment is another
facet of the supply and demand problem. Corruption that trickles to the local
governments, and even the health care workers themselves, leads to some patients
having to pay for medicine or services that should have been free. Reforming
payment systems to ensure that patients have the medicines delivered before
payment is processed directly to the provider will empower the patients and
promote compliance.
Compounding the shortage problems, both of trained workers
and supplies, are the inadequate surveillance systems in place. This is the
third issue that needs to be addressed, and it is arguably the most crucial.
Surveillance is necessary to monitor not only the needs within health
facilities, but also within the community and surrounding areas.
Without real-time tracking of disease and medical supplies,
logisticians, doctors and community health workers are unable to properly
estimate need and completely evaluate the effectiveness of their clinic’s
efforts. This is where data comes into play. The Novartis Malaria Initiative,
under the Roll Back Malaria Partnership, has led SMS for Life, which harnesses
mobile phones, internet, and electronic mapping technology to track stock
levels for health facilities. Sending SMS messages between health facilities
and the district medical officers ensures treatment availability.
Stock-outs have been reduced in Tanzania during a six-month
pilot program from 79% to 26% in three districts. Not only are these stock-outs
reduced, but when they occur, they are also resolved much quicker due to the
ease of communication. In areas where internet is unavailable or running
inconsistently, Relief Watch has offered a similar solution. It also uses
mobile technology, but the application allows workers to not only track
supplies but also disease.
The easy and free setup is invaluable to developing
countries that have previously relied on paper spreadsheets and forms. Giving
workers data at their fingertips gives them more control over their health
facility and their patients. These technological innovations are not only
crucial for immediate supply tracking and disease surveillance, but they
provide research institutions and governing bodies more accurate data. After
all, it is data that public health professionals and policy-makers rely on to
make decisions and plan strategies.
The aforementioned plan to improve health systems is by no means novel. Public health practitioners have stressed the importance of training more workers, creating a steady supply chain of treatments, and addressing surveillance shortcomings for decades.
Solving Africa’s health and development problems takes more
than statements of good intention, empty promises of aid — or movie stars’
adoption of African children. But definitely there are ways to solve them. In
fact, many diseases affecting children and adults can be addressed with minimal
resources — if they are used strategically.
Aid can strengthen civil society and community-based
organizations — which are the basis of a democratic society. To bring hope to a
continent ravaged by poverty and disease, effective action is required. It can
be done.
Nevertheless, more support is needed, particularly from governments,
donors and NGOs to encourage future entrepreneurs to seek to invent new
solutions with the potential to create a lasting impact on the health of hard
to reach communities.
