Lessons Learned from Ebola

~Written by Kelly Ann Hanzlik (Contact: kelly_hanzlik@hotmail.com)

According to the World Health Organization, 28,616 people contracted Ebola and 11,310 lives were lost during the Ebola epidemic. After so many lives lost and the hopeful, but understandably tentative countdown of Ebola free days continues once again in West Africa, it is imperative that we take a moment to consider what we learned from the devastating and tragic epidemic.

I spoke with Dr. Ali S. Khan, former senior administrator for the Centers for Disease Control and Prevention, former Assistant Surgeon General, and current Dean of the University Of Nebraska College Of Public Health. He noted initially, that there is always the risk of importation of cases; that is how it started he reminds us. He elaborated further that the epidemic “changed the response from the WHO and caused a change in political focus by the nations involved that will affect future outbreaks and ensure native capabilities, as well as link them to the global response.” He also noted that new medical counter measures, such as vaccines and related therapeutics, were also the result of the Ebola impact. When asked about what we learned, he did not hesitate. “The first thing was a new vaccine that permits a novel prevention strategy using ring vaccination to prevent spread and new cases. The second is the new monoclonals and antivirals for treatment.” He also noted the better understanding of the viral progression and clinical diseases that will influence options for acute treatment and follow up of convalescents.

Ebola has provided us with a virtual plethora of opportunities to learn about the disease, its treatment and control, as well as the control of other infectious illnesses through our attempts to prevent its spread as well as through our failures, and successes. We gained valuable treatment modalities and tactics that will likely be used in future outbreaks of Ebola, as well as many other infectious diseases.

Ebola taught us other things too. It has been some time since global health has taken center stage. Ebola changed that. During the epidemic, one could not watch the news or go through a day without hearing an update on the latest development in the Ebola crisis. Although other infectious diseases like Plague, Polio, AIDS, SARS, H1N1, Cholera, and now Zika have captured the world’s attention, few diseases have made such an intense impact, nor caused the uproar and fervor that Ebola elicited. Ebola reminded us that global health is public health and affects us all, and as such, deserves to be a priority for national and international focus and funding for everything from vaccine development and research, to capacity for response locally, nationally, and internationally. Global health has teetered on the edge of public awareness, and remained a quiet player in the competition of priorities in national budgets. Today, it is abundantly clear how vital this sector is to each nation’s, as well as the world’s health, safety, success and even its survival.

Another effect from the Ebola crisis was the opportunity to educate people about public health and the transmission of infectious disease. Through education, public health officials were able to promote behaviors that ensured the safety and health of the public. It is stunning that in this day and age, we persist in so many behaviors that put us and those we interact with at risk. The discrepancy in what we say we will do, and what we are actually willing to commit to and take action on, looms large. Persisting low vaccination rates and the prevalence of infectious diseases such as sexually transmitted diseases, measles, pertussis and influenza show this. Ebola offers yet another opportunity to demonstrate the connection between our behaviors and our risks and disease.

Ebola also showed us that many nations continue to lack sufficient financing, infrastructure, facilities, support and medical staff to treat their own populations. Endemic conditions like malaria, and neglected tropical diseases like Guinea worm disease, Yaws, Leishmaniasis, Filariasis, and Helminths, as well as other conditions continue to affect millions globally.  Maternal and childhood morbidity and mortality rates remain deplorable as well. And millions of children around the world continue to suffer and die of malnutrition and disease before they reach the age of five. This is unacceptable, especially because proper treatment and cures for these conditions exist. Ebola also highlighted the need for treatments for chronic non-infectious conditions as well.

Moreover, Ebola clearly demonstrated the enormous need that remains for sufficiently trained medical professionals and healthcare staff to provide adequate care for many populations throughout the world. The loss of so many extraordinary and heroic staff that dedicated their lives to helping others in need under the most daunting and challenging of circumstances was devastating to those whom they served, and must not be in vain.

Additionally, Ebola provided us with yet another chance to relearn lessons about the role of safety in giving aid to others in need. We learned that we cannot just rush in with aid, but must recall the basics that every first responder and medical student must learn:  Ensure scene safety before giving care, and first do no harm. Ebola showed us the necessity to strategize and prepare to give care by utilizing personal protective equipment. It also reminded us very quickly that we could indeed do harm, and worsen the epidemic when we acted without first assessing the situation and ensuring proper protection and preparation.

So, it remains to be seen just how much we will learn from Ebola. Will we learn from our mistakes? Will we take the global view in the future, or the narrow one? Will we truly live by the motto of the Three Musketeers and be "one for all and all for one", or persist in "it's all about me"? Only time will tell. 

Lessons, Impact, and the 'Fearonomics' of the Ebola Outbreak in Nigeria

24th of July.

The day Macchu Picchu was discovered in 1911.

The day Apollo XI returned to the Earth after the first successful mission of taking humans to the moon in 1969. 

Yet, in Nigeria, that day in 2014 will always be marked as the day Patrick Sawyer—the index patient of Ebola—died and set an outbreak in motion in one of the most populated cities in Africa. Patrick Sawyer was a Liberian-American citizen and a diplomat who violated his Ebola quarantine to travel to Nigeria for an ECOWAS convention. His collapse at the airport, coupled with an ongoing strike by Nigerian doctors in public hospitals, landed him at a private hospital in Obalende, where he infected eight other people. 

Patrick Sawyer’s death marked the beginning of an Ebola epidemic in Lagos, a city of 21 million. Lagos is a major economic hub in Africa and one of its biggest cities. An uncontrolled Ebola epidemic would have a far-reaching economic impact beyond the borders of the city, its country, and even its continent.

A recent study has shown that Ebola virus remains active in a dead body for more than a week. Add to this that the body is most infectious in the hours before death, and it is a "virus bomb" waiting to happen if handled incorrectly. West Africa, especially Nigeria, has a strong funeral culture. This Ebola-infected Liberian diplomat’s body was transported and incinerated in accordance with the WHO and CDC protocol. This feat was achieved despite immense political and diplomatic pressure to return the body for funeral rites. It represents one of the many cases of collaboration and "clinical system governance" that are at the heart of the successful containment of Ebola in Nigeria. It is one of the many stories that I'm hoping to highlight in my research on the role of the private sector in Nigeria’s successful Ebola containment.

As part of my research, I am looking at 10 different economic sectors to understand how the Ebola outbreak impacted the private sector and how the private sector dealt with the challenges that the Ebola outbreak posed. My hope is that this research will lead to lessons for the private sector on how, in times of an epidemic, they can help the government to mitigate the disease’s economic impact. I also hope that the resulting report will help governments engage with the private sector more effectively in times of emergencies.

With many outbreaks, especially of highly fatal diseases such as Ebola, fear is the biggest demon. This fear has led to the crippling of economies of Ebola-affected countries. This fear has cost Sierra Leone, Guinea, and Liberia 12 % of their GDP in foregone income and unraveled the years of progress made by these countries. However, this fear is not just a phenomenon limited to West Africa. I had a very personal encounter with this fear recently, when I was quarantined for a few hours in the United States (despite Nigeria being declared Ebola free since October 2014). 

It has been a humbling experience so far, as I try to understand how this fear and the hysteria around Ebola can lead to significant behavioral changes—some of them necessary but some extreme. Everyone I speak to has a story to share. Some people tell of how they bought more than two bus tickets to prevent sitting next to other people. Others tell of hospitals resembling "ghost buildings" as people avoided hospitals and doctors like the plague. Many tell of the "Ebola elbow-shake" that replaced the usual handshake or hug. The reality is that although the Ebola outbreak infected 21 people in Nigeria, it actually affected the lives of 21 million people in Lagos alone, in one way or another. I have come to realize that there is a thin line between precaution and hysteria. Maintaining the equilibrium between the two is the key to controlling the disease and mitigating its economic impact.

As I wrap up my interviews, a few questions resonate with me time and time again from these sessions.

“Are we prepared for the next time?” 

“Ebola is back in Liberia. What can we do to prevent Ebola from coming back to Nigeria?” 

 For the doctors who died in Nigeria’s fight against Ebola:

“Can we truly say our country is a safer place after their sacrifice?” 

And for myself:

“How will your report help Nigeria?”

These are the questions that keep me going. Although my report may not be able to answer all of the aforementioned questions, I do hope it will at least get policy makers, students, and advocacy groups talking about how countries can be better prepared for the next big outbreak and how public-private collaboration can lead a country out of an epidemic and on a path of recovery.

To end on a positive note, 24th July, 2015 also marked one year since the last polio case in Nigeria—an achievement that clearly shows what collaboration in global health can achieve.

Health Issues on the African Horizon for 2015

~ Written by Mike Emmerich - Specialist Emergency Med & ERT Africa consultant (Contact: mike@nexusmedical.co.za)

https://twitter.com/MikeEmmerich 

As 2014 draws to a close and we review what has happened over this past year, we also look forward to 2015 and all of it challenges. Numerous organisations and commentators have written of the challenges that lie over the horizon for 2015, as regards Global Health. From my own experience of working on the continent I have identified the following challenges for 2015 for Africa.

Some of the issues/challenges overlap and/or influence one another. They do not stand alone, the one can exacerbate the other.

Water

Water, on its own, is unlikely to bring down governments, but shortages could threaten food production and energy supply and put additional stress on governments struggling with poverty and social tensions. Water plays a crucial role in accomplishing the continent's development goals, a large number of countries on the continent still face huge challenges in attempting to achieve the United Nations water-related Millennium Development Goals (MDG)

Africa faces endemic poverty, food insecurity and pervasive underdevelopment, with almost all countries lacking the human, economic and institutional capacities to effectively develop and manage their water resources sustainably. North Africa has 92% coverageand is on track to meet its 94% target before 2015. However, Sub-Saharan Africa experiences a contrasting case with 40% of the 783 million people without access to an improved source of drinking water. This is a serious concern because of the associated massive health burden as many people who lack basic sanitation engage in unsanitary activities like open defecation, solid waste disposal and wastewater disposal. The practice of open defecation is the primary cause of faecal oral transmission of disease with children being the most vulnerable. Hence as I have previously written, this poor sanitisation causes numerous water borne disease and causes diarrhoea leading to dehydration, which is still a major cause of death in children in Sub-Saharan Africa.

“Africa is the fastest urbanizing continent on the planet and the demand for water and sanitation is outstripping supply in cities” Joan Clos, Executive Director of UN-HABITAT

Health Care Workers

Africa has faced the emergence of new pandemics and resurgence of old diseases. While Africa has 10% of the world population, it bears 25% of the global disease burden and has only 3% of the global health work force. Of the four million estimated global shortage of health workers one million are immediately required in Africa.

Community Health Workers (CHWs) deliver life-saving health care services where it’s needed most, in poor rural communities. Across the central belt of sub-Saharan Africa, 10 to 20 percent of children die before the age of 5. Maternal death rates are high. Many people suffer unnecessarily from preventable and treatable diseases, from malaria and diarrhoea to TB and HIV/AIDS. Many of the people have little or no access to the most fundamental aspects of primary healthcare. Many countries are struggling to make progress toward the health related MDGs partly because so many people are poor and live in rural areas beyond the reach of primary health care and even CHW's.

These workers are most effective when supported by a clinically skilled health workforce, and deployed within the context of an appropriately financed primary health care system. With this statement we can already see where the problems lie; as there is a huge lack of skilled medical workers and the necessary infrastructure, which is further compounded by lack of government spending. Furthermore in some regions of the continent CHW's numbers have been reduced as a result of war, poor political will and Ebola.

Ebola

The Ebola crisis, which claimed its first victim in Guinea just over a year ago, is likely to last until the end of 2015, according to the WHO and Peter Piot, a scientist who helped to discover the virus in 1976. The virus is still spreading in Sierra Leone, especially in the north and west.

The economies of West Africa have been severely damaged: people have lost their jobs as a result of Ebola, children have been unable to attend school, there are widespread food shortages, which will be further compounded by the inability to plant crops. The outbreak has done untold damage to health systems in Guinea, Liberia and Sierra Leone. Hundreds of doctors and nurses and CHW's have died on the front line, and these were countries that could ill afford to lose medical staff; they were severely under staffed to begin with.

Read Laurie Garrett's latest article: http://foreignpolicy.com/2014/12/24/pushing-ebola-to-the-brink-of-gone-in-liberia-ellen-johnson-sirleaf/

The outcome is bleak, growing political instability could cause a resurgence in Ebola, and the current government could also be weakened by how it is attempting to manage the outbreak.

Political Instability

Countries that are politically unstable, will experience problems with raising investment capital, donor organisations also battle to get a foothold in these countries. This will affect their GDP and economic growth, which will filter down to government spending where it is needed most, e.g.: with respect to CHW's.

Political instability on the continent has also lead to regional conflicts, which will have a negative impact on the incomes of a broad range of households,and led to large declines in expenditures and in consumption of necessary items, notably food. Which in turn leads to malnutrition, poor childhood development and a host of additional health and welfare related issues. Never mind the glaringly obvious problems such as, refugees, death of bread winners etc...

Studies on political instability have found that incomplete democratization, low openness to international trade, and infant mortality are the three strongest predictors of political instability. A question to then consider is how are these three predictors related to each other? And also why, or does the spread of infectious disease lead to political instability?

Poverty

Poverty and poor health worldwide are inextricably linked. The causes of poor health for millions globally is rooted in political, social and economic injustices. Poverty is both a cause and a consequence of poor health. Poverty increases the chances of poor health, which in turn traps communities in poverty. Mechanisms that do not allow poor people to climb out of poverty, notably; the population explosion, malnutrition, disease, and the state of education in developing countries and its inability to reduce poverty or to abet development thereof. These are then further compounded by corruption, the international economy, the influence of wealth in politics, and the causes of political instability and the emergence of dictators.

The new poverty line is defined as living on the equivalent of $1.25 a day. With that measure based on latest data available (2005), 1.4 billion people live on or below that line. Furthermore, almost half the world, over three billion people, live on less than $2.50 a day and at least 80% of humanity lives on less than $10 a day.

Values and Global Health Governance: Lessons from the Ebola 2014 Outbreak

~Written by J. La Juanie Hamilton, PhD Candidate (Contact: lajuaniehamilton@gmail.com)

Twitter: @jasminogen

Values are critical in shaping the global health (GH) dialogue and landscape. Values and the actions that arise from them (virtues) underlie the policies that ensure universal access to necessary health services, adequate responses to health emergencies and resource allocation. Similarly, the values of health governing bodies can create chasms between people and their health necessities. This truth has been unfolding poignantly on an international level during the handling of the Ebola virus disease (EVD) outbreak in West Africa. 
 

What values did the actions or inaction of the international GH community endorse in handling the current EVD outbreak? Although the uniqueness of the outbreak in terms of location and challenges in diagnosis should be considered, many experts agree that the greatest force contributing to the rapid spread of EVD was inaction (1-4). In June 2014, signs that EVD was spiraling out of control throughout Guinea were flashing brightly but the response from the international community remained slow. The exception was Doctors without Borders (MSF), whose staff was already on the ground, helped to diagnose the first case and pleaded for a more robust response from international health governing bodies (3). 
 

Criticisms of health regulatory bodies grew stronger when EVD entered rich countries, which appeared to produce a marked increase in global support efforts. It is hard to say unequivocally, whether this heightened interest and commitment was inevitable or whether the cases in the US and Europe were the impetus. But it is fair to say that many mistakes were made in terms of prioritizing EVD eradication and surveillance. It may also be accurate to say that major economies responded when EVD was perceived as an immediate threat to their economy. This, I believe, is inevitable in a GH system that is built upon a market-driven approach.
 

Can a GH agenda that is framed around economics prioritize the eradication of emerging diseases and neglected diseases of poverty? Although there are compelling arguments for why high-income countries should help to combat EVD and similar diseases, it is unlikely that great achievements will be made without a values shift (5). 
 

A market driven approach inherently prioritizes the need of a few versus the need of many. This model enables the interests of major economies to outweigh the greater good of the whole, if left unchecked. The most important consequence of this approach is that it undermines international health regulatory bodies, whose actions and budgets are heavily influenced by larger economies. This is a problem which, when combined with poor health systems, harmful microbes and permeable borders will inevitably lead to threats in local communities and global security. More importantly, with the movement of people forming a major characteristic of this era, the market driven approach is an unsustainable value upon which to build GH interventions.

There are many points worth considering (schematic above). Major questions moving forward should consider creating a GH model that is more oriented toward equity, security and creativity. Resolutions that create a space in which poor nation states help to set the GH agenda without being threatened by the loss of aid from larger economies must be discussed. Additionally, addressing ways in which the GH dialogue can be re-framed to include stakeholders that currently operate based on virtues stated above should be considered. For example, is there a way to ensure a more official decision-making role for organizations like MSF?

What is next for GH governance and what will the values shift towards? EVD 2014 is a strong indicator of the limits of theoretical values, political indifference and passivity in achieving health and well-being for all. But the stories emerging from West Africa provide an opportunity for EVD 2014 to serve as a “meaning making” event in GH. It provides an impetus for changing priorities from passive verbiage of values of human dignity to a model of creativity, equity and accountability which proactively contextualizes GH policies, innovation and interventions.

Infectious Diseases Come from Animals? - Zoonotic Transmission

~Written by Theresa Majeski (Contact: theresa.majeski@gmail.com)

For those people who have been following the Ebola outbreak relatively closely or who have been doing their own research into Ebola, you may have heard that scientists think Ebola is introduced into the human population through fruit bats and/or the butchering of bush meat. 

This concept of infectious diseases passing between animals and humans is not new and is called zoonotic transmission. Now Ebola is a virus, but other disease causing agents such as bacteria, parasites and fungi can also be spread between animals and humans. While you may not have heard of zoonotic transmission before, I bet you’ve heard of some zoonotic diseases. Examples include anthrax, Lyme disease, Avian influenza, plague, malaria, dengue, West Nile virus infection, and rabies. The WHO says there are over 200 zoonotic diseases known to us thus far. I also bet you didn’t know that about 75% of recently emerging infectious diseases affecting humans are of animal origin and approximately 60% of all human pathogens are zoonotic. (I just learned these facts as well and am sufficiently surprised the numbers are that high). 

So how in the world does someone get a zoonotic disease? Well, for instance, anything transmitted by mosquitos or ticks are zoonotic diseases, so take proper precautions to prevent being bitten by all ticks and mosquitos. You can also come into contact with zoonotic diseases through petting zoos, pet stores, nature parks, farms, etc. Our beloved pets can also transmit diseases like salmonella, hookworm, and roundworm. The moral of the story is to make sure you’re washing your hands after handling animals and to be careful about petting every fluffy creature you come across. 

Now I would be missing a big part of the picture if I didn’t investigate some of the human-induced reasons why more and more of the population is in danger of being directly impacted by these “remote” zoonotic diseases. Zoonotic diseases transmitted by mosquitos for example, generally only impact people living in areas where those mosquito species are found. Climate change is allowing for some of these mosquitos to expand their territory, thereby bringing zoonotic diseases to new areas of the world. For example, two mosquito species known to carry malaria are now found at the US-Mexican border. Additionally, our expanding population and changes in how humans are migrating are causing interactions with species we’ve never encountered before through practices such as forest clear-cutting and wetland draining. 

I have no easy solutions to these problems as they stem from much larger human population growth issues. But the good news is that we, as humans, have noticed that zoonotic diseases are a growing issue and have stepped up efforts to stay on top of things. The European Union has passed legislation requiring member states to increase their monitoring of zoonotic diseases and has specific guidelines on how to do that. Self-proclaimed “Virus Hunter” Nathan Wolfe did a TED Talk on how his team and he are working on the frontlines of novel virus detection by using innovative ways to collect specimens, detect, and track previously unknown viruses in humans. (I highly recommend watching the talk even if you’re not really interested in emerging infectious diseases as it provides a practical look into the challenges of doing fieldwork in remote areas where these diseases are coming from.)

The important thing to take away from all this information is that zoonotic diseases are almost unavoidable as we humans are interacting with our world, and that world includes all sorts of known and unknown pathogens. By prioritizing innovative ways for early detection we can hopefully learn about potential diseases and create possible remedies before they become global pandemics

Challenges on the Frontlines of Ebola

~Written by Marilyn Perez Alemu (Contact: marilyn.perez@gmail.com) 

Healthcare workers on the frontlines of the Ebola crisis in West Africa are daily putting their lives at risk to save the lives of others. The current epidemic is the largest of its kind in history, exacerbated by a reported 70% case fatality rate. Yet Ebola is a disease that knows no mercy. Since the initial outbreak reported in March, more than 450 healthcare workers have been infected in Liberia, Sierra Leone, Guinea and Nigeria. More than 200 have died.

Despite being faced daily with this reality, as well as the looming stigmatization from their communities and families, healthcare workers continue to provide medical support to Ebola victims for the sake of those who will survive the disease. The initial international response was markedly slow and, as the outbreak intensifies, emerging challenges have severely impacted the ability of healthcare workers to respond to the growing need.

When executed properly, contact tracing is a key method for containing the outbreak spread. Ideally each contact, or person linked to a confirmed or probable case, would be identified by a healthcare worker and monitored for 21 days following exposure, allowing public health officials to track the movement of the outbreak. In theory, contact tracing is an effective method to ensure early detection of infections and immediate treatment, and stem the spread of the virus. Essentially, contact tracing has been called the key to “stop Ebola in its tracks”. And while the process seems simple enough, critical information gaps, limited databases, and an exponential increase in the number of Ebola cases have led to a breakdown in contact tracing in West Africa. With limited infrastructure and many living in remote villages, even finding patients is a challenge. Add that to the fact that people are often uncooperative with tracers, as the fear of going to a health center is something akin to a death sentence. Without the ability to do complete and proper contact tracing, rapid diagnosis and patient isolation is hindered and the outbreak will continue to spiral out of control.

While past outbreaks of Ebola were sporadic and contained within small rural areas, the current outbreak poses a serious challenge in that it has spread quickly to more crowded urban areas in West Africa. In rural areas, population density is lower, community ties are stronger, and transmission prevention measures are presumably easier to implement. Now, in vastly overpopulated urban areas, Ebola transmission has accelerated exponentially and the outbreak has gone beyond the ability to contain it. Control and prevention measures have thus intensified in both innovation and urgency, evidenced by accelerated efforts in vaccine development and experimental therapeutics.

While an Ebola outbreak is caused biologically, an Ebola epidemic is a crisis of poverty and fragile health systems. West Africa is faced with the repercussions of a weak health infrastructure, including scarcity of healthcare workers, limited resources, and poor management systems. It should be noted that these shortcomings preceded the Ebola outbreak, with just 51 doctors to serve Liberia’s 4.2 million people and 136 for Sierra Leone’s population of 6 million. To put this in context, this is fewer than many clinical units in a single hospital in the United States. Having worked its way through the cracks of a fragile health infrastructure, Ebola has effectively brought healthcare to a halt in Liberia, Sierra Leone and Guinea. An added complication is the shortage of resources, including personal protective equipment (PPE) and other control materials, and the lack of straightforward protocols and guidelines. Efforts must increase not only to ensure an ample supply of optimal PPE but also to effectively disseminate information on proper use of the equipment.

At the frontlines of the Ebola outbreak, healthcare workers face a daunting challenge. In Liberia, Emmanuel Boyah, a primary health manager with the International Rescue Committee, recounts the stress and fear of this work. Yet he and many others continue to dedicate themselves to the cause and risk their lives to care for those affected: “I feel that providing services to people during this time, when they’re in need of you, is my call.”

Vaccines and Gavi to the Rescue for Millions of Children

~Written by Theresa Majeski (Contact: theresa.majeski@gmail.com)

As talk continues to increase about an Ebola vaccine possibly becoming a reality in a couple months, I thought I’d offer a larger look at vaccines in general and how Gavi, the Vaccine Alliance, is helping ensure children in the poorest parts of the world can take advantage of lifesaving immunizations.

Many people have probably heard of Edward Jenner and his smallpox variolation which served to immunize people against smallpox. But this sort of variolation, taking fresh matter from a sore of someone suffering from an infectious disease and inserting that under the skin of a healthy person to cause an immune response resulting in the variolated person being immune to the disease, had been taking place in Africa, India and China long before Edward Jenner was even born.

The work done by Jenner and his predecessors were humanity’s first attempts at controlling an infectious disease through vaccination.

In the current era we have vaccinations for many of the infectious diseases that previously plagued many of the world’s richer nations, and still plague many of the poorer nations. Some may argue that we have too many vaccinations here in the West and that we are causing more harm than good through our childhood vaccinations. I’m not here to argue that particular topic with readers but if you’re interested in reading some science-based information about vaccines you can find that here, here, and here.

What I want to focus on is how vaccines have taken us from a world where millions upon millions of children died every year from infectious diseases and how the only hope for stopping an outbreak was quarantine, to a world where many of these infectious diseases are rarely seen in richer countries and are on the difficult path to being controlled in many lower income countries around the world. Now this is not to say that outbreaks of these vaccine preventable diseases such as polio, measles, and whooping cough, to name a few, are not occurring in the US, Europe, or Asia. They are, as evidenced by this interactive map from the Council on Foreign Relations.  We still have work to do that is for sure. But organizations like Gavi are focusing on eradicating these infectious diseases in middle and low income countries around the world, where these diseases exact a high toll.

So to put the effect of vaccines into perspective:

• 3 million lives are saved worldwide every year due to vaccines
• 1 child dies every 20 seconds from vaccine preventable diseases worldwide
• The United States has seen a 99-100% decrease in cases of diphtheria, measles, H. influenza, mumps, rubella, congenital rubella, polio and smallpox due to vaccinations
• Vaccines save the US $42 billion a year in medical costs and lost productivity

The incidence of many of these vaccine preventable diseases is still high in many of the poorer countries of the world; enter Gavi, the Vaccine Alliance. Gavi helps save children’s lives and protect people’s health by increasing access to immunizations in poor countries. Gavi is a public-private partnership with The Bill & Melinda Gates Foundation, WHO, UNICEF, and the World Bank. Gavi works with health ministries in 77 countries to use existing frameworks to deliver vaccines to those in need. Since 2000, Gavi has contributed to the immunization of 440 million children with another 243 million immunized between 2011 and 2015. These efforts amount to averting an estimated 3.9 million deaths from 2011 to 2015 due to vaccine preventable diseases.

Vaccines save lives; it’s as simple as that. Those vaccines we take for granted here in the US are the difference between life and death for many children in lower income countries. Gavi, the Vaccine Alliance is working to make those vaccines accessible to those who need them most. 

Politics and Medicine

~Written by Mike Emmerich, Specialist Emergency Med & ERT Africa Consultant (Contact: mike@nexusmedical.co.za)

"Medicine is a social science, and politics is nothing else but medicine on a large scale"—Rudolf Virchow

Politics is defined as "organised human behaviour", thus we can postulate that Medicine is micro managed organised human behaviour, at times right down to the molecular level. If we examine the Ebola outbreak/s (globally) and how it is being managed on a macro (politics) and micro scale (medicine) we can begin to see the cracks in the system, and hopefully then move to addressing these cracks, before they begin yawning chasms that are not repairable.

The region (Liberia, Sierra Leone and Guinea) has had success (we could add Nigeria and Senegal to the successes) and failures in both areas. Neither is Spain and the USA exempt from this analysis as can be noted from the various press releases (government and medical) over the past few months.

Since the first outbreaks in 1976 (Sudan and The DRC) till the current one in West Africa; care has generally been palliative and symptomatic, questions have often been asked during this period; What of a vaccine and/or other means of treating the infected patients? There was a report in the British Sunday Times (12/10/14), cited a Cambridge University zoologist as saying that “it is quite possible to design a vaccine against this disease” but reported that applications to conduct further research on Ebola were rebuffed because “nobody has been willing to spend the twenty million pounds or so needed to get vaccines through trial and production”. Globally this has been one of the failures of the pharmaceutical companies, and most probably even the WHO, for not pushing harder over the years to get this in motion.

In her 1994 book /The Coming Plague: Newly Emerging Diseases in a World Out of Balance http://lauriegarrett.com/#item=the-coming-plague, //Laurie Garrett warned that there are more than 21 million people on earth “living under conditions ideal for microbial emergence.” http://www.independent.co.uk/arts-entertainment/science-mutating-microbes-1601604.html Garrett when on to win the Pulitzer Prize in 1996 for reporting on Ebola. In 1995 Joshua Lederberg, the American molecular biologist said: "The world is just one village. Our tolerance of disease in any place is at our own peril. Are we better off today than we were a century ago? In most respects, we're worse off. We have been neglectful of the microbes, and that is a recurring theme that is coming back to haunt us."

Jump forward to the 23^rd of September 2014, US President Obama issued an unprecedented ‘Presidential Memorandum on civil society http://www.whitehouse.gov/the-press-office/2014/09/23/presidential-memorandum-civil-society’ recognising that: Through civil society, citizens come together to hold their leaders accountable and address challenges that governments cannot tackle alone. Civil society organisations…often drive innovations and develop new ideas and approaches to solve social, economic, and political problems that governments can apply on a larger scale./

If we look at the current crises in West Africa civic leaders are what is missing, hence the inability to track and trace potential infected persons, motivate communities to change risky behaviours (handing of the deceased), agitate with government to create better health care systems, this all adds fuel to the fire of the current epidemic.

Have we listened and learnt as governments, NGO's and Multinational Pharmacare companies since then?

Despite Medical Advances, Millions Are Dying, this is a banner from 1996, not 2014! from the WHO, which was "declaring a global crisis and warning that no country is safe from infectious diseases, the World Health Organization says in a new report that diseases such as AIDS, Ebola, Hanta, Mad Cow, tuberculosis, etc., killed more than 17 MILLION people worldwide last year”.

As Laurie Garrett wrote in her the closing section of her book, The Coming Plague, /“In the end, it seems that American journalist I.F. Stone was right when he said, ‘Either we learn to live together or we die together.’ While the human race battles itself, fighting over ever more crowded turf and scarcer resources, the advantage moves to the microbes’ court. They are our predators, and they will be victorious if we, Homo sapiens, do not learn how to live in a rational global village that affords the microbes few opportunities. It’s either that or we brace ourselves for the coming plague.” Time is short.

The Ebola outbreak in West Africa is “unquestionably the most severe acute public health emergency in modern times,” Dr. Margaret Chan, the director general of the World Health Organization, said Monday 20/10/2014). We do seem to be going in circles... circa 1995.. have we learnt nothing from history.

Global Ebola Involvement

As a passionate and committed African, having spent the past 20 years working in various countries on my continent, and having seen the effects of colonisation, globalization, war as a result of minerals and commerce (funded by big western businesses) and how Africa is marginalised via trade and commerce. Never mind the fact that all the ex-French colonies still pay tax to France, even years after independence!!

It is also true that Africa’s problems are also created by many corrupt Africa politicians and greedy emerging markets in Africa.

What should our response be, in the event of disasters, war, famine or in the case of Ebola (disease outbreaks). As a human race we all live in a global village and we cannot and should not stand by when we see our fellow man/woman suffering; be it in Syria, Ukraine or in this case West Africa (Guinea, Sierra Leone and Liberia). Every effort should be made to help when and how we can, be it with manpower, resources or financial aid. This is not a regional or Africa problem, but a global one.

The entire Southern West Africa region is still emerging from a decades long conflict (partly made infamous by Blood Diamonds) and their are trails ongoing in the Hague re this conflict. One could even argue that western powers (corporate and country) were complicit in this conflict, hence they should now have at least an ethical (if not moral) motivation to get involved. Far to often we stand on the sides and wring our hands at the mess Africa is in and that it never seems to get out of this mess (that in itself is another long missive for another day/blogpost).

Now the region needs beds (hospitals) and staff to man them, there is a huge shortage of beds. The one thing that this epidemic (as most of them do) has taught us that it is gloves not vaccines that will make the difference. Good basic hygiene, clean water, bleach/chlorine and excellent palliative care in a sterile environment will make a difference. Those who have survived, have survived for these reasons.

All of the above needs to sustainable in the medium to long term and the affected countries must be encouraged through means of trade and commerce to make these changes real and lasting. I know this last paragraph sounds pie in the sky, but the rich western countries and corporates (Large Pharma) in this case must commit to push for it to happen; not for their end gains and an increase in share price (my cynical comment re what is motivating large Pharma in this case), but for the good of the region.

People in West Africa will have to alter behaviours, we won’t stop this outbreak solely by building hospitals. There will have to be a change in the way the community deals with the disease. Changing behaviour which is so closely linked to culture, tribe and religion will not happen in the short term. Meaning that the worst case scenario could come to fruition, which is over 100,000 cases by the 1st of December. (as outlined in some disease modelling programmes!)

Government ministers in the region must focus within their communities and regions on the key ways to manage this outbreak. They need to be out in the field as the voice of government, pushing for the necessary societal changes hat need to take place. The region needs beds, hospitals and basic supplies. Beds and hospitals is not being dealt with as urgently as it should be by local governments, they are waiting for outside funders to step in, they must drive the initiative on the ground and mobilise local leaders to work with their villages to manage this outbreak, otherwise the worst case scenarios that are being punted look scary. Both MSF and WHO are pushing for this, but they need local governmental support.

My closing comment is that gloves not drugs (vaccines) will save the day. Basic good clean sanitary medicine and palliative care, aligned with sound symptomatic treatment will save lives, for that we need beds, hospitals, staff and supplies, from across the globe, Cuba has stepped into the breach while others (Australia) are still wringing their hands.
