CEU eTD Collection iv CENTRAL EUROPEAN UNIVERSITY ABSTRACT OF THESIS Submitted by: Slobodan Tofiloski For the degree of Master of Science and entitled: Geospatial analysis of water-associated infectious diseases: Case of Myanmar Month and Year of submission: July, 2018. Water can serve as a medium for pathogenic organisms, posing substantial health treats to humans through the variety of pathways. Water-associated infectious diseases are a major cause of morbidity and mortality in Myanmar. The recent environmental and social changes in Myanmar have significant influence over water-associated infectious diseases and it is expected for that trend to continue in future. Alterations in climate factors, human migration caused by several ongoing armed conflicts, low levels of sanitation, difficult access to clean drinking water, increased agricultural practices and industrialization; all of them can change the patterns of distribution, emergence, and re-emergence of the water-associated infectious diseases in Myanmar. This research utilizes the social and environmental determinants mentioned above and water-associated prevalence data in conjunction with a GIS analysis method, to present the distribution and risk of the water-associated diseases in Myanmar and their relation with diverse factors. The results show that Yangon has the highest number of waterborne diseases outbreaks and second highest number of water-related diseases outbreaks. Results also show that there is CEU eTD Collection specific interconnected influence of different factors, with some of them dominating in certain states or regions. KEYWORDS: GIS analysis, Myanmar, water, water-associated diseases, social and environmental factors. v Table of Contents Acknowledgements ....................................................................................................................................... iv Table of figures ............................................................................................................................................. vii Table of tables ............................................................................................................................................. viii List of Abbreviations ...................................................................................................................................... ix 1.

INTRODUCTION As many professionals involved in the management of water resources do not have a medical or public health background, it was thought that an explanatory bibliography of the major water related diseases in South Africa would be of use. Each section of the bibliography has (where appropriate) the following sections: 1. Aetiology 2. Transmission 3. Preventive and curative steps 4. South African data 5. References The MEDLINE data base of the national Library of Medicine, Washington DC, and the WATERLIT data base of the CSIR were searched. These were supplemented by South African journals and reports not appearing in the MEDLINE data base. 3 2. AMOEBIASIS 2.1. Aetiology The protozoan parasite Entamoeba histolytica which causes amoebiasis may exist as a hardy infective cyst or a more fragile and potentially pathogenic trophozoite (the "amoebic" form). Amoebiasis most commonly affects the colon and rectum as primary sitas of infection, with extraintestinal (most commonly liver abscesses), local or systemic, spread possible if not treated early.

In the last 25 years of the 20th century the pandemic intensified, with increased geographic spread of both the viruses and the principal mosquito vec- fever and dengue tor, Aedes aegypti. This led to larger and more frequent epidemics and to the emergence of DHF as tropical countries and regions became hyperendemic with hemorrhagic fever the co-circulation of multiple virus serotypes. With the exception of sporadic epidemics in the Caribbean islands, in the Americas: dengue and yellow fever were effectively controlled in the Americas from 1946 a case of failed until the late 1970s as a result of the Ae. aegypti eradication program conducted by the Pan American Health Organization (PAHO) (1, 2). This was a vertically struc- public health policy tured, paramilitary program that focused on mosquito larval control using source reduction and use of insecticides, primarily dichlorodiphenyltrichloroethane (DDT). This highly successful program, however, was disbanded in the early 1970s because there was no longer a perceived need and there were competing 1 Duane Gubler priorities for resources; control of dengue and yellow fever was thereafter merged with malaria control. Another major policy change at that time was the use of ultra-low-volume space sprays for killing adult mosquitoes (adulticides) as the rec- ommended method to control Ae. aegypti and thus prevent and control DF and DHF. Both of these decisions were major policy failures because they were inef- fective in preventing the re-emergence of epidemic DF and the emergence of DHF in the Region.

They are several groups of water-linked illnesses, according to the part water shows in the transmission method of illness : these contain: water-borne illnesses, water-washed diseases, water-based diseases, water related insect vector diseases and inhalation diseases. The large cause of these diseases are human or animal waste matter, industrial activity or be parts of normal or disturbed systems.

  • Early History of Infectious Disease 
    © Jones and Bartlett Publishers. NOT FOR SALE OR DISTRIBUTION CHAPTER ONE EARLY HISTORY OF INFECTIOUS 1 DISEASE Kenrad E. Nelson, Carolyn F. Williams Epidemics of infectious diseases have been documented throughout history. In ancient Greece and Egypt accounts describe epidemics of smallpox, leprosy, tuberculosis, meningococcal infections, and diphtheria.1 The morbidity and mortality of infectious diseases profoundly shaped politics, commerce, and culture. In epidemics, none were spared. Smallpox likely disfigured and killed Ramses V in 1157 BCE, although his mummy has a significant head wound as well.2 At times political upheavals exasperated the spread of disease. The Spartan wars caused massive dislocation of Greeks into Athens triggering the Athens epidemic of 430–427 BCE that killed up to one half of the population of ancient Athens.3 Thucydides’ vivid descriptions of this epidemic make clear its political and cultural impact, as well as the clinical details of the epidemic.4 Several modern epidemiologists have hypothesized on the causative agent. Langmuir et al.,5 favor a combined influenza and toxin-producing staphylococcus epidemic, while Morrens and Chu suggest Rift Valley Fever.6 A third researcher, Holladay believes the agent no longer exists.7 From the earliest times, man has sought to understand the natural forces and risk factors affecting the patterns of illness and death in society. These theories have evolved as our understanding of the natural world has advanced, sometimes slowly, sometimes, when there are profound break- throughs, with incredible speed. Remarkably, advances in knowledge and changes in theory have not always proceeded in synchrony. Although wrong theories or knowledge have hindered advances in understanding, there are also examples of great creativity when scientists have successfully pursued their theories beyond the knowledge of the time.
