The purpose of this chapter is to offer reflections on conventional theories concerning causes and determinants of diseases. It also intends to examine both theoretical and empirical bases for adopting an Integrated Social-Ecological Systems (ISES) lens as a tool for understanding complexities related to drivers, determinants and causes of diseases.

We assessed the theoretical underpinnings of a range of historical and contemporary lenses for viewing infectious disease drivers and the implications of their use when used to explain both personal (i.e. individual) and population health. We examined these issues within the empirical context of the City of Dhaka (Bangladesh) by adopting an ISES lens. Within this study an emphasis has been placed on illustrating how feedback loops and non-linearity functions in systems have a direct bearing upon various aspects of infectious disease occurrences.

A brief triumph over microbes during the last century stemmed in part from our improved understanding of disease causation which was built using disciplinary-specific, monocausal approaches to the study of disease emergence. Subsequently, empirical inquiries into the multi-factorial aetiology and the ‘web of causation’ of disease emergence have extended frameworks beyond simplistic, individualistic descriptions of disease causation. Nonetheless, much work is yet to be done to understand the roles of complex, intertwined, multi-level, social-ecological factors in affecting disease occurrence. We argue, a transdisciplinary-oriented, ISES lens is needed to explain the complexities of disease occurrence at various and interacting levels. More theoretical and empirical formulations, with evidence derived from various parts of the world, is also required to further the debate.

Our study advances the theoretical as well as empirical basis for considering an integrated human-nature systems approach to explaining disease occurrence at all levels so that factors at the individual, household/neighbourhood, local, regional and global levels are not treated in isolation.

Much of the discussion surrounding the antivaccine movement focuses on the decision of parents to not vaccinate their children and the resulting danger posed to others. However, the primary risk is borne by the child left unvaccinated. Although living in a developed country with high vaccination rates provides a certain amount of protection through population immunity, the unvaccinated child is still exposed to a considerably greater risk of preventable diseases than one who is vaccinated. I explore the tension between parental choice and the child’s right to be free of preventable diseases. The chapter’s goal is twofold: to advocate for moving from a dyadic framework – considering the interests of the parents against those of the state – to a triadic one, in which the interests of the child are given as much weight as those of the parent and the state; and to discuss which protections are available, and how they can be improved. Specific legal tools available to protect that child are examined, including tort liability of the parents to the child, whether and to what degree criminal law has a role, under what circumstances parental choice should be overridden, and the role of school immunization requirements in protecting the individual child.

There is no doubt that global climate change poses a threat to human health in a number of ways. Globally, 23% of all deaths in 2012 were attributed to the environment and an additional 250,000 potential deaths per year from 2030 to 2050 due to the effects of climate change. Heat waves, storms, droughts and floods pose an immediate risk of infectious diseases in humans. Temperature affects the survival rates of pathogens. Some populations and some areas are more vulnerable to infectious diseases due to their lack of ability to respond effectively to the stresses of high temperatures. Excessive rainfall could cause sewage to overflow and promote the onset and spread of infectious diseases ranging in severity from mild gastroenteritis to life-threatening illnesses such as cholera, dysentery and other diseases. Infectious diseases are a category of health problems that are particularly affected by climate change. Infections that occur are air-borne, water-borne and zoonotic. They are affected by the increase of the temperature, but also by the increase of the viral load in the water due to changes in the rainfall. Transmission can also take place through the migration of environmental refugees. Such an important topic could be the subject for students learning English. The purpose of this study will be to highlight the association of climate change with infectious-communicable diseases in order to take action and to create the structure by which students could learn English by studying these definitions.

The Epidemiologic Transition can help us understand a fundamental puzzle about aging. The puzzle stems from two seemingly contradictory facts. The first fact is that death rates from noninfectious degenerative maladies – the so-called diseases of aging – increase as people age. It seems to be at odds with the historical fact that for nearly a century in which people were aging more than ever before, the aggregate rates of such diseases have been decreasing. In what sense can both be true? Crucial to resolving the puzzle are the age-profiles of such diseases in cohorts that grew up in the different regimes of the Transition. For each cohort, noninfectious diseases had increased with age, resulting in an upward-sloping age profile, which affirms the first fact. As the regimes were transitioning from the Malthusian to the modern one, however, the profiles of successive cohorts had been shifting downward: death rates from noninfectious diseases were shrinking at each age, signifying the newer cohorts’ greater aging potentials. The shifting profiles had been renewing the cohort mix of the population, shaping the century-long descent of such diseases in aggregate, giving rise to the historical fact. The profiles had shifted early in the cohorts’ adult years, associating closely with the newer epidemiologic conditions in childhood. Those conditions appear to be a circumstance under which aging potentials of cohorts could be misgauged, including in one troubling episode in the first half of the nineteenth century when the potentials had reversed.

Objective – To present the challenges arising from the double burden of disease in developing countries, focusing on the case of Mexico, and to propose a strategy for addressing these challenges.

Methodology/approach – Mortality and morbidity data are presented for selected countries and groups of diseases. Specific examples of the pressures faced by the public health services in Mexico to provide and finance treatment for communicable and non-communicable diseases are used to illustrate the extent of the challenges in the context of a country with limited resources.

Findings – Public health systems in developing countries face strong pressure to provide and finance treatment for both communicable and non-communicable diseases, inevitably producing competition among diseases and conditions and requiring trade-offs between equity and efficiency goals.

Implications for policy – In developing countries, addressing the challenges presented by the double burden of disease requires a multidisciplinary approach to develop and strengthen the policymaking process. This involves the use of analytical tools applied to each stage of the planning cycle, in particular the use of an explicit priority setting process together with monitoring and assessment to strengthen decision making under limited resources.

Misinterpretation of a negative test results in health screening may initiate less preventive effort and more future lifestyle-related disease. We predict that misinterpretation occurs more frequently among individuals with a low level of education compared with individuals with a high level of education.

The empirical analyses are based on unique data from a randomized controlled screening experiment in Norway, NORCCAP (NORwegian Colorectal Cancer Prevention). The dataset consists of approximately 50,000 individuals, of whom 21,000 were invited to participate in a once only screening with sigmoidoscopy. For all individuals, we also have information on outpatient consultations and inpatient stays and education. The result of health behaviour is mainly measured by lifestyle-related diseases, such as COPD, hypertension and diabetes type 2, identified by ICD-10 codes.

The results according to intention-to-treat indicate that screening does not increase the occurrence of lifestyle related diseases among individuals with a high level of education, while there is an increase for individuals with low levels of education. These results are supported by the further analyses among individuals with a negative screening test.

Minamata disease was first officially recognized in May 1956. Its earliest victims were small children. Environmental contamination most rapidly and seriously affected the physiologically weak among the residents. However, the outbreak of the disease in humans was preceded by abnormalities in the natural environment such as massive death of fish and shellfish, and the abnormal behavior and death of cats. It used to be considered that poisoning was caused by direct exposure to a toxic substance, and that toxic substances did not pass the placenta. Minamata disease is an indirect poisoning by methyl mercury through the food chain as a result of environmental contamination, and is the first known disease to cause abnomalities in the fetus due to a toxic agent passing through the placenta. Minamata disease, therefore, had implications in various fields. Namely it also stirred up legal, ethical, and eugenic arguments concerning fetal protection. This report reviews the course of Minamata disease, and evaluates its impacts. “Minamata Studies” has three intellectual and scientific missions to change the social systems that caused the disease; to pursue environmental justice; and to explore the possibility of an environment that permits coexistence not only of all humans, but of all living things.

Purpose – Purpose of the research is to make a comprehensive study to elucidate the existing landscape of scientific production of disease outbreaks, pandemics and tourism research. In doing so, authors analyzed scientific production of pandemics and tourism-related studies such as year-wise publications, productive authors, institutes, funding sponsors, thematic areas of research and citation analysis.

Design/methodology/approach – Authors analyzed the research papers indexed in the online Scopus database over 50 years of time starting from 1971 to 2020 by using bibliometrics, and the data are visualized by using data visualization tools like VOSviewer and the Tableau.

Findings – The understanding of disease outbreaks and pandemics in tourism has increased over the years in terms of number of papers, citation, networks and collaborative themes of research.

Research limitations/implications – Data for the study were generated from Scopus online database and limited to English-written journal articles that were produced with search strategy of specific keywords associated with tourism, virus, pandemics and disease outbreak.

Practical implications – Findings of the research provide insights into academia and practitioners on the understanding of disease outbreaks, pandemics and tourism research, coherent development of the concept and understanding the research gap and focussed area of research.

Originality/value – As per authors' understanding, this paper would be one of the first attempts to provide greater understanding of disease outbreaks, pandemics and tourism as a research topic by examining the growth and evolution in an academic context through bibliometric analysis.

Paper type – Review paper.

The internationally well known Minamata disease caused by methyl mercury poisoning, which has been described as a great tragedy of the modern Japanese state in the 20th century, in terms of a particular history of the “soul” narratives and practices is discussed. These narratives and practices are sometimes excluded from the authentic narratives in the state. I am exploring a historical vision connecting to the future of the Minamata disease victims as the “souls” of the Minamata disease after the “Final Settlement” in 1996. The paper's goal to suggest the “souls” of the Minamata disease is becoming out of place and it was articulated to some local people who experienced tragedies in the colonial or post-colonial situations.

Over the last decades, there has been an increasing interest among scientists on the linkage between population health and climate and environmental factors, as well as health impacts of climate change and climate variability. Numerous studies have been done and substantial results achieved, but mostly in the developed countries, and not much quantitative evidence or assessment of the impacts at national and local levels has been provided for developing countries.
