As revolting as it sounds, there are places in the world where the chances of consuming one’s neighbours’ faeces are quite high if one is not vigilant regarding sanitation and hygiene. That being the condition of many areas in low and lower-middle income countries does not mean that high and higher-middle income countries are exempt from any environmental conditions that are harmful to health.

But, what is environment health? The World Health Organization (WHO) defines the term as, “All the physical, chemical, and biological factors external to a person, and all the related factors impacting behaviours”. It, however, excludes genetics and the social and cultural environment.

In low-income settings, concerns for environmental health may arise in the context of sanitation and hygiene, as well as indoor and outdoor pollution. In high-income countries, many chronic diseases like diabetes and cardiovascular disease, are associated with sedentary lifestyles. While these might be attributed to behaviour, one must consider that such behaviours can arise from changes in the environment. Over 80% of communicable and non-communicable diseases can be attributed to environmental hazards.  Overall, conservative estimates indicate that about one quarter of the total global burden of disease is owing to this cause (WHO, 2011). Furthermore, the biggest killers of children under 5 years are all environmental-related diseases, including diarrhoea, respiratory infections, and malaria.

Other diseases of concern are helminthic infections, trachoma (a bacterial eye infection), Chagas disease, leishmaniosis, onchocerciasis, and dengue fever. All of which are associated with impoverished conditions and can be mitigated by improving sanitation, hygiene, and housing. Although conflicts and natural disasters might be catastrophic for any country, struggling economies tend to suffer more because disasters worsen the poor conditions which directly affect sanitation and hygiene practices, creating conducive conditions for various infectious diseases, and ultimately feeding into the vicious cycle of poverty.

Many interventions are underway to address these conditions, including Water, Sanitation and Hygiene (WASH) initiatives, Integrated Vector Management, Programme on Household Air Pollution, International Programme on Chemical Safety, Health and Environment Linkages Initiative, and Intersun Programme for the effects of UV radiation. The acknowledgement of the effects of the environment has grown. One of the Millennium Development Goals (MDGs) was, “To ensure environmental sustainability.” The Sustainable Development Goals (SDGs) are more extensive and thorough in placing focus on the environment. Goal 1 is to end poverty, goal 6 is to make provision of clean water and sanitation possible, and goal 13 is to stop climatic change resulting in floods and drought (United Nations, 2014).

It is encouraging to see steps being taken to control environmental hazards; however, the journey to measuring and eradicating such conditions still remains a challenge, which will hopefully be overcome through future endeavours.

Access to Toilets: Not as Common as You Might Think

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

There are over seven billion people on the planet and 2.4 billion of them do not have access to proper sanitation. Almost one billion people still defecate in the open. The risk of disease and malnutrition increases with poor sanitation, especially for women and children. This year’s World Toilet Day on November 19 highlights the impact of poor sanitation on malnutrition.

Every day, over 1,000 children die from preventable water and sanitation related diarrheal diseases. Half of all cases of under-nutrition associated with diarrheal or intestinal worm infections are directly due to inadequate water, sanitation, and hygiene. Stunting and wasting, which cause irreversible physical and cognitive damage, have been linked to poor (water, sanitation and hygiene (WASH) conditions. In 2014, almost 1 in 4 children under five years of age suffered from stunting globally. 58% of all cases of diarrheal disease are directly related to inadequate water, sanitation, and hygiene.

Access to proper sanitation, hygiene, and potable water is so important that it was included in the 2000 Millennium Development Goals (MDG). Since 1990 an additional 2.1 billion people have started using basic toilets, and today around 68% of people have access to proper sanitation. However, the final MDGs Assessment report shows that the world has fallen short of the MDG goal by 700 million people. This means that there is still work to be done, which is why access to sanitation and clean water is Goal 6 of the Sustainable Development Goals.

There are many innovations occurring in the WASH area. One example is a project by Give Water that promotes child health by developing child-sized latrines and teaching children about proper sanitation and hygiene practices in school. This ensures that proper WASH practices start from a young age. The WASH Impact Network website provides a lot of information about additional innovative WASH projects. 

Access to proper sanitation and clean water is a human right. While progress is being made towards this goal, there is still work to be done. World Toilet Day highlights the continued effort to provide proper sanitation facilities to every person on the planet.

Examining How Women are Influenced by Inaccessibility to Clean Water

~ Written by Joann Varickanickal (Contact: joann.varickanickal@gmail.com)

Since 1990, 2-3 billion people have gained access to improved drinking water sources, however, much is yet to be done, as billions still do not have access to safe drinking water (Dora, et al., 2015). This has led to several negative health consequences among many communities, as one-third of deaths are linked to the intake of contaminated water in low-resourced countries (West & Hirsch, 2013). Women are often responsible for housework such as cooking, cleaning and maintaining good hygiene. They are also mainly responsible for the care of children and the sick. As all of these tasks require the use of water, women in low-resourced countries are disproportionately affected by the inaccessibility to safe water.

Risks Associated with Water Collection

In 71 percent of households in sub-Saharan Africa women are responsible for collecting water (West & Hirsch, 2013).  As a result, in places such as the mountainous areas of Eastern Africa, women use up to 27 percent of their caloric intake to get water (West & Hirsch, 2013). Sometimes, they must travel a long distance, often several times in one day. This can lead to physical strain, especially among the elderly. This strain can be exacerbated by extreme heat or with heavy pumps at well sites. Water collection can also be dangerous in remote locations where there is increased risk of rape or other forms of violence.

Impacts on Women as Caretakers, and the Terminally Ill

With a high prevalence of HIV and AIDS in these regions, there has also been an increase in care needed for the terminally ill, and once again, it is the responsibility of the woman to provide the needed care (West & Hirsch, 2013). This involves emotional support, but also other aspects such as bathing and toileting. Providing this type of assistance can become more difficult when there is little accessibility to clean water. Furthermore, caregivers also have an increased chance of developing physical pain and infections because of the risks they are exposed to. Increasing accessibility to clean water will not only improve the outcomes of HIV treatment, but it will also reduce the burden of care on women. As a result, this can improve the quality of life for both groups (Figure 1).

Overall, inaccessibility to clean water increases the emotional distress on women and reduces the level of care they are able to provide to those around them. When mothers have poor health status they are unable to provide the adequate resources needed for the well being of their children, which can lead to growth stunts (Requejo, et al., 2015).

Like any other public health issue, this one is complex. Many factors must be examined to determine how improvements can be made to increase the availability of safe water, while also empowering women. For example, while women have to travel long distances in order to get clean water, this also gives them a chance to socialize with other women and spend some time away from the home. Thus, what can be done to preserve this time for social interaction, while minimizing the health risks?  In order to answer this and similar questions, governments and NGOs must critically analyze social systems, specifically gender norms, health systems and physical infrastructure in low-resourced countries.

Civil Unrest and the Global Polio Eradication Efforts

~Written by  Kate Lee - MPH Epidemiology, Vanderbilt University Medical Center (Contact: kathleen.g.lee@vanderbilt.edu)

Vaccine-preventable illnesses are an ongoing global health issue. Just in the United States alone there have been outbreaks of measles and pertussis (whooping cough) from parents refusing to vaccinate their children. In 2013, California had over 9,000 people infected with pertussis. As of September 2014, the United States had almost 600 measles cases. For every 1,000 children getting infected with measles, 1 to 2 will die. There will be continuous outbreaks of diseases once thought to have been controlled or eradicated if parents do not adhere to the immunization schedule for their children. This is, however, an argument for another day.

Despite all of this, the United States no longer has ongoing transmission of one of the more debilitating illnesses that affected a lot of children in its peak during the 1950s: polio. This is, of course, due to vaccination campaigns. Since the launch of global polio eradication efforts in 1988, polio incidence has dropped to more than 99%. What can be said of these efforts in parts of the world that are not as stable economically, politically, or socially? In early 2014 India celebrated its third year without wild-type polio. In 2013, the African continent had 274 cases of polio but only 22 in 2014. Overall in 2014, there were 350 cases of polio, down from 416 in 2013 in the African continent. Ongoing poliovirus transmission occurs in three endemic countries: Nigeria, Afghanistan, and Pakistan. Although poor sanitation is a risk factor for polio, prevention of vaccination is the biggest risk one that these countries face.

Mistrust, misconceptions, and religious reasons all feed into public notions of vaccination. Political unrest may be one of the most important obstacles in the global campaign to end polio. Boko Haram insurgency has led to civil unrest in areas of northern Nigeria where ongoing polio transmission occurs. There has been a decline in polio cases in Afghanistan since the Taliban has allowed vaccination in recent years, but that has not been the case for Pakistan. The Pakistani Taliban and other Islamist groups have led killings of health care workers in an anti-immunization campaign. These militant groups threaten not only health care workers that administer the vaccines to the communities, but also the parents who offer vaccination for their children. Since the Pakistani Taliban ban on immunizations in 2012, more than 60 polio workers have been killed. The result of this has been Pakistan counting its 260th case of polio as of November 2014.

Sadly, the political unrest feeds into public mistrust, resulting in a cycle that perpetuates civil instability and polio transmission, leaving the $10 million global eradication effort hanging in the balance. Some health authorities are questioning if the polio campaign is worth it. Lives are lost, health resources are wasted, and new strategies must be reached to continue the immunization effort in Pakistan. Many individuals wonder why polio should be a priority when the country is undergoing so many more problems. There are a variety of other infectious diseases that place the population at risk due to poor sanitation and malnutrition. Outside of health, the threat of the Taliban hangs over the heads of the population. But, why would the Taliban target immunization campaigns? Part of the answer lies in negotiating leverage to stop drone strikes from the United States. The other part of the answer is rooted in a CIA campaign in 2012 to hide Osama bin Laden intelligence operations through the guise of immunization campaigns. Polio in Pakistan is not the first disease to be heavily affected by political unrest and exploited by militant groups, and it sadly may not be the last. What is extremely crucial to understand is that health and politics are not mutually exclusive.

This theme of political cooperation is constant throughout every public health issue. The global effort to erase polio is not an exception. Militant groups, however, now present an added obstacle in achieving social and political stability so that health care workers can conduct their tasks peacefully. Families and vaccinators should not have to fear that their lives are at risk for undertaking public health activities. Rethinking the immunization strategy in Pakistan is necessary. Improvement of basic health services and sanitation are starting points not just for polio, but a multitude of other infectious diseases. These campaigns are important, but take time and money to come to fruition, two resources that are becoming scarcer in a very unstable country.

Malnourishment: A Growing Concern - Food as a Weapon

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

https://twitter.com/MikeEmmerich

The number of hungry people has fallen by over 200-million since 1992, so says the 2014 Hunger Map and a report titled “The State of Food Insecurity in the World: Strengthening the Enabling Environment for Food Security and Nutrition” jointly prepared by World Food Programme (WFP), the Food and Agriculture Organisation (FAO) and the International Fund for Agricultural Development (IFAD).

They go on to say that 805 million people, or one in nine of the world’s population, go to bed hungry each night. But in Sub-Saharan Africa, this is even worse, with one in four people suffering from undernourishment. The report says that sub-Saharan Africa faces the most severe challenges in securing its food; mainly due to sluggish income growth, high poverty rates and poor infrastructure, which hampers physical and distributional access.

It states: “In general, in Africa, there has been insufficient progress towards international hunger targets, especially in the sub-Saharan region,”

The report also says limited progress had been made in improving access to safe drinking-water and providing adequate sanitation facilities, while the region continues to face challenges in improving dietary quality and diversity, particularly for the poor. I did some work in the Southern DRC (based out of Lubumbashi in 2006) and we noted then that dehydration, was the leading cause of death in children under the age of 5. Dehydration as the result of diarrhoea, caused by unsanitary drinking water. For those who survive they are then in turn faced with stunted growth, which is made worse by poor food nourishment.

This report just published confirms that the situation has not changed in the past 8 years, limited progress had been made in improving access to safe drinking-water and providing adequate sanitation facilities. In fact the report notes, that progress has been so poor, that the WFP target of halving the number of undernourished people by 2015, will not be realised.

The report highlights the following to move forward:

1. Sustained political commitment at the highest level

2. Placing food security and nutrition at the top of the political agenda

3. Creating an enabling environment for improving food security and nutrition through adequate investments

4. Better policies, legal frameworks and stakeholder participation

5. Institutional reforms are also needed to promote and sustain progress.

Plus an integrated plan focussing on:

1. Public and private investments to raise agricultural productivity

2. Better access to inputs, land, services, technologies and markets

3. Measures to promote rural development

4. Social protection for the most vulnerable (persons and countries)

5. Including strengthening their resilience to conflicts and natural disasters

6. Specific nutrition programmes, especially to address micro-nutrient deficiencies in mothers and children under five.

As reports go it is a very good piece of work tackling many complex issues and outlining clear broad action plans. As with most reports though, I take issue with their expected outcomes, to broad, not specific and in my opinion, to broad. Its like position papers from government departments or even aid agencies. It does not tackle the problem head stating what is at fault and what needs to be done in clear action plans; to do that will require stepping on toes or worse – maybe even naming names!

Regional conflicts, greedy power hungry warlords all demanding access to food, how it is priced and distributed. This can affect when and if crops are planted, and who gets the produce, and they who sells it. Food can be and is used as a weapon, to control people or even to get votes, Zimbabwe and South Africa are cases in point.

The cost of food is then another key factor, Lester Brown wrote in 2011's “Food Issue” of the Foreign Policy magazine:/ Americans generally spend less than 10% of their income on food, but there are 2 billion people who live in poverty around the globe who spend 50 to 70 percent of their income on food/. A slight increase in the cost of food for these persons could be life or death, and the costs when they do escalate, are beyond the control of the consumer, at times manipulated by external forces, for their own (political or economic) gain.

On a sad and macabre note, Saudi Arabia, South Korea and China ventured beyond their borders in 2008 to grow grain in cheaper regions, such as Ethiopia and Sudan, where, of course, people where starving and did not get any of the planted grain.

So where to from here; I think if we cast our eyes to Burkina Faso, we might see a way out, People Power. The people need to speak and speak loudly in the only way the politicians and regional leaders will listen.
