Haganum Model United Nations 2015| 13th of March –15th of March 2015 Forum: Special Conference Issue: Strengthening the coordination of healthcare in African countries regarding cholera Student Officer: Zuzanna Nowak Position: Deputy President Introduction Cholera is a diarrheal illnes caused by ingestion of the bacterium Vibrio Cholerae. The bacterium is mainly to be found in faeces-contaminated water, which is why the cholera is a problem of an epidemic scale in the countries with the poorest sanitation. Approximately 5-10% of patients face severe stage of disease, which is characterized by profuse diarrhea, leg cramps and vomiting. Such symptomps can relatively quickly lead to fatal dehydration if left untreated. However, in case of cholera treatment plays a significant role and is not at all hard to implement. Measures such as oral or intravenous rehydration can reduce the ratio of fatality to less than 1% (meaning that with proper treatment less than 1 in 100 patients will die of cholera). In developed, well-infracstructured countries cholera is a rarely occuring and not so dangerous illnes. In Africa, however, its range is overwhelmingly big and it kills thousands of people every year. The main reason for such frequent occurance of cholera in this particular region is its limited access to safe water as well as lack of hygiene and poor sanitary conditions. 2 RESEARCH REPORTS
Haganum Model United Nations 2015| 13th of March –15th of March 2015 Definition of Key Terms Diarrhea The main symptom of cholera, likely to cause patient’s dehydration due to rapid fluid loss. Rehydration A process of replenishing fluids lost by a patient in a course of disease by delievering them from the outside, which can be done eighter oraly or intervenously. Rather inexpensive and uncomplicated method of treatment, especially effective in cholera cases. Dukoral® and ShanChol® Two types of WHO*-prequalified, effective oral vaccines for cholera available on the market. Both of them are licensed in over 60 countries. Dukoral provides short-term protection of 85-90% among all age groups while ShanChol provides long-term protection among children under five years of age. *World Health Organization Background Information Why Africa? One of the most important things to realize about cholera is that the death rate among treated patients remains very low, while the disease left untreated can kill an adult person within hours. That is why healthcare plays such a significant role here. Unfortunatelly, poor economic condition of the country does not favour implementing effective and pro-active healthcare, which is partly the reason for African countries to find cholera so bothering. Furthermore, the weaker a patient’s immune system is, the more severe course will his illness take. Malnourished, neglected people, suffering from famine and poverty are the ones most exposed to the fatal outcome of cholera infection. The percentage of people dying from reported cholera cases remains higher in Africa than enywhere else in the world. 3 RESEARCH REPORTS
Haganum Model United Nations 2015| 13th of March –15th of March 2015 Because Vibrio Cholerae bacteria are present in contaminated water, it is understandable why the disease spreads so wildely in underdeveloped African states, such as Sierra Leone, Niger, Guinea or Zimbabwe. Cholera transmission is closely linked to inadequate environmental management. Typical at-risk areas include peri-urban slums, where basic infrastructure is not available, as well as overcrowded camps for internally displaced people or refugees, where minimum requirements of clean water and sanitation are not met. In Africa cholera remains a global threat to public health and a key indicator of lack of social development. Recently, the re-emergence of cholera has been noted in parallel with the ever-increasing size of vulnerable populations living in unsanitary conditions. How does cholera spread so rapidly? Another factor that contributes to the epidemic scale of cholera is the fact that not all infected people will develop recognizable symptoms. Why is that so dangerous? Statistically speaking, in case of one hundred people getting infected, about one person in five will get severe diarrhea (without proper treatment, up to half of them may die). The rest of the infected people will develop mild symptoms or no symptoms at all. In fact, the majority of them might not even realize they carry the bacteria in their system. Given their fine physical condition, they will feel well enough to function - travel, for example - and potentionally infect others. A perfect example of how dangerous this mechanism is would be the cholera outbreak in Haiti, where the infection began in only one of the departments and within just over a month it spread all across the country. That is one of the reasons why awarness raising must be emphasized. People of Africa need to realize that their not-well-being may potentially be much more dangerous to the community than they would assume. What do the numbers show? For the reasons of cholera occuring in underdeveloped areas and its symptoms being similar to a number of other diarrheal diseases, it is drastically under-recognized and underreported. Therefore the statistics regarding cholera are rather inacurate. An estimated number of cholera cases reaches up to 3–5 million every year, with about 100 000–120 000 deaths. Now, an exceedingly important massage is that over 90% of patients could be succesfully treated if provided with proper medical attention. 4 RESEARCH REPORTS
Haganum Model United Nations 2015| 13th of March –15th of March 2015 Major Countries and Organizations Involved UNICEF “UNICEF currently provides strategic technical support and guidance including the UNICEF Cholera Toolkit (available in English and French), surge capacity, training, supplies and logistical support for cholera and diarrhoeal disease outbreak prevention, preparedness and response worldwide. UNICEF supports governments, the World Health Organization (WHO) and partners in the following areas: advocacy, coordination, assessments, planning and prioritization, surveillance, early warning systems and alert mechanisms, service delivery and communication. In addition, UNICEF supports the appropriate use of the oral cholera vaccine (OCV) with other priority cholera control interventions and has been a key partner in the development of the Global OCV Stockpile.” (http://www.unicef.org/cholera/) World Health Organization (WHO) The organization of an international range of activity and interest, supporting UNICEF in its attempts to combat cholera outbreaks in Africa, cooperating with local medical facilities and introducing scientific studies aimed at reducing harmfulness of cholera. Also, they are a main source of statistical data regarding infectious diseases, such as cholera itself. Somalia, Sierra Leone, Congo, Mozambique, Nigeria, Zambia, Zimbabwe, Guinea, Uganda, Rwanda The examples of African countries in which cholera outbreaks took the most dangerous form. Hundreds of citizens with no access to safe water got (and still get) infected with V. cholerae. In areas such as peri-urban slums, where people live on the brink of poverty, toilets are frequently replaces with latrines or ground pits. The faeces are likely to contaminate soil or get eluted with rain and further contaminate the environment. Knowing that slums inhabitants use mainly unfiltered water from rivers, streams, makeshift wells or even puddles, the bacteria spreads among them relatively quickly and the outcome is dramatic. Because of the 5 RESEARCH REPORTS
Haganum Model United Nations 2015| 13th of March –15th of March 2015 quantity of patients and inadequate number of healthcare facilities, a vast majority of infected people - including large number of children - do not receive proper treatment, nor basic education about how cholera spreads, how to protect yourself from it or how to aproach your symptoms. At the worst times, hospitals are so overcrowded they cannot take in any more patients. Lack of required equipment and educated staff does not help eihter, which results in thousands of deaths every year.

A number of hygiene promoters took part in collective efforts towards tackling cholera by going door to door and providing citizens with basic health education. UNICEF has also been trying to deliver rehydration kits to as many Africans in at-risk areas as possible, to enable them to 7 RESEARCH REPORTS
Haganum Model United Nations 2015| 13th of March –15th of March 2015 treat new cholera cases urgently. What is more, UNICEF sets up numerous handwashing facilities as a part of their cholera-prevention plan. Infusions, antibiotics and drips are sent to local hospitals, to by any means increase their effectiveness and scope of action. Also, existing feeding centers for malnourished children are provided with safe drinking water. Chlorine supplies - used for treating unsafe water sources, such as wells - are being distributed across African countries. Those fundamental measures are certainly helpful, but rather extemporary. Lack of quality medical facilities, educated staff and basic equipment leaves thousands of Africans defenseless in face of cholera infection. Deplorable sanitation and widespread poverty of the region make it even more difficult to successfully implement prevention measures, let alone treat an overwhelming number of infected patients. Water supplies deliverd by NGOs and their partners are salutary, but not big enough. Same problem applies for rehydration kits, medicines and qualified menpower. Possible Solutions Well, solutions for this problem are not as much complicated, as they are hard to implement. To resolve the question of cholera epidemic we must dive deeply into its causes and try to treat the issue at its very core. I would suggest adressing poverty and famine (especially in peri-urban slums) as the main reasons for cholera to constitute such danger in this particular region of the world. Furthermore, please remember that raising awarness always plays a significant role in cases like this. With so many Africans still not knowing what cholera is, how it spreads or how to properly aproach an actual infection, the problem is only likely to grow and evolve. As for prevention, which is a next exceedingly important element of healthcare, limited access to safe water in African countries is a key factor here. While writing your resolutions, try aiming at implementing solid sewege systems, as well as delivering running water and WHO-certificated reservoires to residential areas. Remember: sanitation and hygiene can never be over-emphasized when it comes to water-born diseases. Keep in mind that the majority of cholera infected Africans are children under the age of five. They therefore represent the age group that ought to be surveilled most closely and taken the greatest care of. Other than that, you might want to think ahead and include in your 8 RESEARCH REPORTS

It could be a chain of specialized clinics, widespread vaccination program or whatever you can think of. Last but not least, I would suggest acknowledging NGOs’ actions. Without governmental resources (both human and financial) the NGOs are not able to solve the problem all by themselves, but their work does create a solid foundation for you to build on and a framework to turn into quality ideas.
