As doctors and biologists have learned, to their dismay, infectious disease is a moving target: new diseases emerge every year, old diseases evolve into new forms, and ecological and socioeconomic upheavals change the transmission pathways by which disease spread. By taking an approach focused on the general evolutionary and ecological dynamics of disease, this Very Short Introduction provides a general conceptual framework for thinking about disease. Ecology and evolution provide the keys to answering the "where", "why", "how", and "what" questions about any particular infectious disease: where did it come from? How is it transmitted from one person to another, and why are some individuals more susceptible than others? What biochemical, ecological, and evolutionary strategies can be used to combat the disease? Is it more effective to block transmission at the population level, or to block infection at the individual level? Through a series of case studies, Benjamin Bolker and Marta L. Wayne introduce the major ideas of infectious disease in a clear and thoughtful way, emphasizing the general principles of infection, the management of outbreaks, and the evolutionary and ecological approaches that are now central to much research about infectious disease.

Public health is a term much used in the media, by health professionals, and by activists. At the national or the local level there are ministries or departments of public health, whilst international agencies such as the World Health Organisation promote public health policies, and regional organisations such as the European Union have public health funding and policies. But what do we mean when we speak about 'public health'? In this Very Short Introduction Virginia Berridge explores the areas which fall under the remit of public health, and explains how the individual histories of different countries have come to cause great differences in the perception of the role and responsibilities of public health organisations. Thus, in the United States litigation on public health issues is common, but state involvement is less, while some Scandinavian countries have a tradition of state involvement or even state ownership of industries such as alcohol in connection with public health. In its narrowest sense, public health can refer to the health of a population, the longevity of individual members, and their freedom from disease, but it can also be anticipatory, geared to the prevention of illness, rather than simply the provision of care and treatment. In the way public health deals with healthy as well as sick people it is therefore a separate concept from health services, which deal with the sick population. Drawing on a wide range of international examples, Berridge demonstrates the central role of history to understanding the amorphous nature of public health today.

The immune system is central to human health and the focus of much medical research. Growing understanding of the immune system, and especially the creation of immune memory (long lasting protection), which can be harnessed in the design of vaccines, have been major breakthroughs in medicine. In this Very Short Introduction, Paul Klenerman describes the immune system, and how it works in health and disease. In particular he focuses on the human immune system, considering how it evolved, the basic rules that govern its behavior, and the major health threats where it is important. The immune system comprises a series of organs, cells and chemical messengers which work together as a team to provide defence against infection. Klenerman discusses these components, the critical signals that trigger them and how they exert their protective effects, including so-called "innate" immune responses, which react very fast to infection, and "adaptive" immune responses, which have huge diversity and a capacity to recognize and defend against a massive array of micro-organisms. Klenerman also considers what happens when our immune systems fail to be activated effectively, leading to serious infections, problems with inherited diseases, and also HIV/AIDS. At the opposite extreme, as Klenerman shows, an over-exaggerated immune response leads to inflammatory diseases such as Multiple Sclerosis and Rheumatoid Arthritis, as well as allergy and asthma. Finally he looks at the "Immune system v2.o" - how immune therapies and vaccines can be advanced to protect us against the major diseases of the 21st century.

HIV/AIDS is without doubt the worst epidemic to hit humankind since the Black Death. Despite rapid scientific advances, there is still no cure and the drugs are expensive and toxic. In some of the worst affected countries, life expectancy has plummeted to below 35 years, which has led to a serious decline in economic growth, a sharp rise in orphaning, and the imminent collapse of health care systems. This Very Short Introduction tackles the science, the international and local politics, the fascinating demographics, and the devastating consequences of the disease, and explores how we have - and must - respond.

The twentieth century saw a remarkable upsurge of research on drugs, with major advances in the treatment of bacterial and viral infections, heart disease, stomach ulcers, cancer, and metal illnesses. These, along with the introduction of the oral contraceptive, have altered all of our lives. There has also been an increase in the recreational use and abuse of drugs in the Western world. This Very Short Introduction, in its second edition, gives a non-technical account of how drugs work in the body. Reviewing both legal (alcohol, nicotine, and caffeine) and illegal drugs, Les Iversen disscusses why some are addictive, and whether drug laws need reform.

In 2008 it was believed that HIV/AIDS was without doubt the worst epidemic to hit humankind since the Black Death. The first case was identified in 1981; by 2004 it was estimated that about 40 million people were living with the disease, and about 20 million had died. Yet the outlook today is a little brighter. Although HIV/ AIDS continues to be a pressing public health issue the epidemic has stabilised globally, and it has become evident it is not, nor will it be, a global issue. The worst affected regions are southern and eastern Africa. Elsewhere, HIV is found in specific, usually, marginalised populations, for example intravenous drug users in Russia. Although there still remains no cure for HIV, there have been unprecedented breakthroughs in understanding the disease and developing drugs. Access to treatment over the last ten years has turned AIDS into a chronic disease, although it is still a challenge to make antiviral treatment available to all that require it. We also have new evidence that treatment greatly reduces infectivity, and this has led to the movement of 'Treatment as Prevention'. In this Very Short Introduction Alan Whiteside provides an introduction to AIDS, tackling the science, the international and local politics, the fascinating demographics, and the devastating consequences of the disease. He looks at the problems a developing international 'AIDS fatigue' poses to funding for sufferers, but also shows how domestic resources are increasingly being mobilised, despite the stabilisation of international funding. Finally Whiteside considers how the need to understand and change our behaviour has caused us to reassess what it means to be human and how we should operate in the globalizing world.
