Los virus son noticia. Desde el surgimiento de pandemias como el VIH, la gripe porcina o el SARS, constantemente estamos siendo bombardeados con información sobre nuevas infecciones letales. La última y más dramática es el SARS-CoV-2. En esta breve introducción, Dorothy Crawford muestra hasta qué punto los virus resultan inteligentes y son, con mucho, las formas de vida más abundantes del planeta.En esta segunda edición actualizada, Crawford relata la historia de virus asesinos por todos conocidos, como el ébola y Zika, así como el virus del MERS, el SARS-Cov-1 y el Sars-Cov-2, causante de la pandemia de la covid-19, y analiza cómo en el siglo XXI los viajes aéreos facilitan la propagación internacional de los virus. También evalúa los efectos del calentamiento global, que ha hecho aumentar la dispersión de virus transmitidos por vectores como el dengue, la fiebre amarilla y el virus del Nilo Occidental, y adelanta los efectos que esto tendrá en las poblaciones de climas subtropicales y templados de América, Australasia y Europa. Asimismo, explora el papel que desempeñan los virus en el control del medio marino, pues hay casi dos mil millones de ellos en cada litro de agua de mar y resultan esenciales para el delicado ecosistema del océano. Finalmente, tras examinar nuestro actual estilo de vida, Crawford mira hacia el futuro para preguntarse si alguna vez podremos vivir en armonía con los virus y cómo deberíamos actuar para prevenir las consecuencias devastadoras asociadas a algunos virus emergentes.

Ever since we started huddling together in communities, the story of human history has been inextricably entwined with the story of microbes. They have evolved and spread amongst us, shaping our culture through infection, disease, and pandemic. At the same time, our changing human culture has itself influenced the evolutionary path of microbes. Dorothy H. Crawford here shows that one cannot be truly understood without the other. Beginning with a dramatic account of the SARS pandemic at the start of the 21st century, she takes us back in time to follow the interlinked history of microbes and man, taking an up-to-date look at ancient plagues and epidemics, and identifying key changes in the way humans have lived - such as our move from hunter-gatherer to farmer to city-dweller -- which made us vulnerable to microbe attack. Showing how we live our lives today -- with increasing crowding and air travel -- puts us once again at risk, Crawford asks whether we might ever conquer microbes completely, or whether we need to take a more microbe-centric view of the world. Among the possible answers, one thing becomes clear: that for generations to come, our deadly companions will continue to shape human history. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.

bVery Short Introductionsb: Brilliant, Sharp, Inspiring /b Viruses are everywhere, and as the COVID-19 pandemic has shown, cannot be ignored. From their discovery to the unravelling of their intricate structures, this Very Short Introduction provides a rounded and concise account of the nature of viruses, how they attack their hosts, and the efforts to control them. In this new edition, Dorothy H. Crawford examines the recent rise in emerging virus infections, especially coronaviruses, including the viruses behind SARS and MERS, and SARS CoV-2 responsible for COVID-19. Crawford explores why the SARS-CoV-2 was able to spread rapidly to form a pandemic while others have produced more localized epidemics, as well as looking at the revolution in vaccine production that this has caused. Looking to the future, this Very Short Introduction considers the preventative measures and management of future dangerous viruses that are expected to emerge. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

For all our hubris, humans can be felled rapidly by an invisible enemy - viruses. All around us are minute entities that can damage and kill: the millions of viruses that pervade the natural world. Our bodies harbour many that we have long tolerated, but a new one, that jumps into humans from another species, can be lethal - as we have seen most recently with the virus responsible for COVID-19. But what are viruses, how do they cause disease, and how can we fight them? In Viruses: The Invisible Enemy, a brand new edition of her classic work, virologist Dorothy Crawford explores these questions. She takes the reader on a journey through the past to show how, as the human race evolved from hunter gatherer to farmer to our present urban, industrialised society, viruses have taken advantage of each lifestyle change to promote their own survival. We have acquired many new viruses along the way, some spreading globally and causing killer diseases. But now, in the 21st century, as humans increasingly encroach into and exploit the natural world, the rate of emergence of novel viruses is accelerating. Already we've had a flu pandemic, large epidemics from SARS, Ebola and Zika viruses, and most devastating of all, SARS-CoV-2, which swept around the world in 2020-21, causing the COVID-19 pandemic. The response of scientists has been rapid, producing vaccines in record time. But we can expect more such challenges in the future. This book discusses why and how SARS-CoV-2 and other killer viruses emerged, and how we can win the battle against such an enemy.

The Epstein-Barr virus (EBV) was discovered in 1964. At the time, the very idea of a virus underlying a cancer was revolutionary. Cancer is, after all, not catching. Even now, the idea of a virus causing cancer surprises many people. But Epstein-Barr, named after its discoverers, Sir Anthony Epstein and Dr Yvonne Barr, is fascinating for other reasons too. Almost everyone carries it, yet it is only under certain circumstances that it produces disease. It has been associated with different, apparently unrelated, diseases in different populations: Burkitt's Lymphoma, producing tumours in the jaw, in African children; a nasal tumour in China; glandular fever in Europe and the USA; and the majority of cases of Hodgkin's Disease everywhere. This book tells the story of the discovery of the virus, and the recognition of its connection with these various diseases - an account that spans the world and involves some remarkable characters and individual stories.
