The El Niño Modoki/La Niña Modoki (ENSO Modoki) is a newly acknowledged face of ocean-atmosphere coupled variability in the tropical Pacific Ocean. The oceanic and atmospheric conditions associated with the El Niño Modoki are different from that of canonical El Niño, which is extensively studied for its dynamics and worldwide impacts. A typical El Niño event is marked by a warm anomaly of sea surface temperature (SST) in the equatorial eastern Pacific. Because of the associated changes in the surface winds and the weakening of coastal upwelling, the coasts of South America suffer from widespre

Chapter 2 (‘Patterns of health inequalities’) sets the scene for the rest of the book, by explaining the measurement of health inequalities and by providing a profusely illustrated overview of inequalities in morbidity and mortality by education and occupational class in 30 European countries. It shows that health inequalities are a generalized phenomenon affecting young and old, men and women, and all aspects of health, but with important differences by age, gender, and type of health problem. It shows that health inequalities are present in all European countries, but with striking variations between countries, suggesting that there is great scope for reducing health inequalities. It also shows that although health inequalities are persistent, they are also highly dynamic, with relative inequalities often increasing and absolute inequalities sometimes declining over time. This chapter includes a comparison with other high-income countries (United States, Canada, Australia, New Zealand, Japan, and South Korea).

Demographic transition refers to a shift in reproductive behavior from a state of high birth and death rates to a state of low birth and death rates. This transition takes place because of advances in agricultural technology and medical science or improvement in hygiene environment, all of which result in corresponding declines in the mortality rate. In this first phase of the demographic transition, population growth rises because the decline in mortality rate has not been coupled with any significant change in parents’ fertility decisions. Then, in the second phase of the transition, parents begin to reduce their fertility as they realize that their ideal number of children can be more easily achieved with fewer births. The widespread use of contraceptive techniques facilitates parents’ attempts to reduce fertility, which in turn causes a decline in the population growth rate. Eventually, the population growth rate converges to a new level, which may be higher or lower than in the pretransitional stage. To facilitate comparison, we can use figure 11.1 to characterize the time and process of the transition. In figure 11.1, Tα marks the apparent starting point of a continuous decline in mortality. Tβ, which normally occurs later than Tα, refers to the time at which the fertility rate begins to decline. Tγ, is the point of lasting return, with an average rate of natural increase equal to or less than that of the period preceding the date of Tα. The convention is to define D = Tγ - Tα as the duration of the transition period. Chesnais (1992) separated the observations of world demographic transition into several types. The first type includes developed countries in Europe and Japan; the second type consists of countries with immigrant European populations, such as the United States, Australia, and Argentina; late-developing countries, such as India. South Korea, and Jamaica, belong to the third type. For countries of the first type, the mortality decline process is closely related to the development of medical technology, which was gradual and spread out over time; hence, the demographic transition is also long. Late-developing countries and those with large immigrant populations were able to adopt the already-developed medical technology from the advanced countries at one time.

In Chapters 4–8, we have examined a series of processes that, often working in combination, have served to precipitate the emergence and re-emergence of infectious and parasitic disease agents in the human population. In this chapter, we conclude our survey with an analysis of temporal trends in disease emergence and re-emergence since 1850. The discussion is informed by long-term shifts in the underlying causes of mortality encapsulated in Omran’s model of epidemiological transition (Section 1.4.1), paying particular attention to the manner in which sample infectious and parasitic diseases have waxed and waned at a variety of geographical scales from the global to the local over the last ∼150 years. Our choice of examples strikes a balance between coverage of geographical regions and epidemiological environments, and coverage of important diseases that we have not so far examined in detail. Our consideration is structured by geographical scale: (1) At the global level, we discuss three major human diseases that have undergone phases of rapid global expansion since 1850—plague, cholera, and HIV/AIDS (Section 9.2). (2) At the regional level, we examine twentieth-century trends in general infectious disease mortality in the advanced economies of Europe, North America, and the South Pacific, 1901–75, before looking at time sequences for sample emerging (Ebola–Marburg) and cyclically re-emerging (meningococcal) diseases in sub-Saharan Africa (Section 9.3). (3) At the national level, we use Hall’s (1993) data to establish the main trends in morbidity due to infectious diseases in Australia, 1917–91 (Section 9.4). (4) At the local level, we extend our examination of long-term disease trends in London, described for the pre-1850 period in Section 2.4, into the late twentieth century (Section 9.5). The chapter is concluded in Section 9.6. In this section, we examine long-term trends in three major human infectious diseases that have undergone phases of global expansion in the last 150 years: plague (Section 9.2.1); cholera (Section 9.2.2); and HIV/AIDS (Section 9.2.3).
