The story of viruses and humanity is a story of fear and ignorance, of grief and heartbreak, and of great bravery and sacrifice. Michael Oldstone tells all these stories as he illuminates the history of the devastating diseases that have tormented humanity, focusing mostly on the most famous viruses. For this revised edition, Oldstone includes discussions of new viruses like SARS, bird flu, virally caused cancers, chronic wasting disease, and West Nile. Viruses, Plagues, and History paints a sweeping portrait of humanity's long-standing conflict with our unseen viral enemies.  

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.

Despite advances in health care, infectious microbes continue to be a formidable adversary to scientists and doctors. Vaccines and antibiotics, the mainstays of modern medicine, have not been able to conquer infectious microbes because of their amazing ability to adapt, evolve, and spread to new places. Terrorism aside, one of the greatest dangers from infectious disease we face today is from a massive outbreak of drug-resistant microbes.

The hunt for the origin of the AIDS virus began over 20 years ago. It was a journey that went around the world and involved painstaking research to unravel how, when, and where the virus first infected humans. Dorothy H. Crawford traces the story back to the remote rain forests of Africa - home to the primates that carry the ancestral virus - and reveals how HIV-1 first jumped from chimpanzees to humans in rural southeast Cameroon. Examining how this happened, and how it then travelled back to Colonial west central Africa where it eventually exploded as a pandemic, she asks why and how it was able to spread so widely.

The enormous human and economic toll of the rapidly spreading COVID-19 disease offers a vivid reminder that infectious disease pandemics are one of the greatest existential threats to humanity. This book provides an accessible explanation of how viruses emerge to cause pandemics, how our immune system combats them, and how diagnostic tests, vaccines, and antiviral therapies work - concepts that are a foundation for our public health policies. 

Explore em Vírus que nos assombram a aterradora disseminação dos maiores vírus que marcaram a história recente da saúde global. De epidemias devastadoras a pandemias que pararam o mundo, a obra revela o impacto dos microrganismos mais temidos, detalhando como surgiram, se espalharam e foram combatidos. Com particularidades científicas e históricas, conheça os desafios enfrentados por médicos e pesquisadores na batalha para conter essas ameaças invisíveis.

Malária, sífilis, tuberculose, ebola, gripe, aids, sarampo e outros males que atacam a humanidade revelam muito mais da nossa história do que imaginamos. Os passos do homem ao longo das épocas, pelos continentes, o início da utilização de vestimentas, a convivência com diversos animais, o encontro com outros seres humanos: tudo isso pode ser desvendado agora com o estudo microscópico de vírus, bactérias e parasitas que cruzaram - e cruzam - o nosso caminho.

Vaccines, Viruses, and Villains explores the tangled web of public health, power, and perception. Blending investigative critique with compelling storytelling, the book dives into the origins of medical controversies—from the vaccine-autism debate to the influence of elite figures and institutions. It questions official narratives, highlights suppressed voices, and examines how fear, misinformation, and control intersect in modern medicine.

"Mientras escribo esto, a lo largo del año 2015, los científicos intentan adelantarse a las próximas pandemias. Nadie es capaz de predecir cuándo una cepa en particular llevará a cabo el salto, si acaso lo hará. Sin embargo, no estamos indefensos ante lo que la evolución pueda tenernos reservado. Contamos con recursos para contrarrestar la expansión de la gripe, como lavarnos las manos. Y los científicos están aprendiendo a fabricar vacunas más efectivas. Al menos, ya no tenemos que mirar hacia las estrellas en busca de protección." — Carl Zimmer

In Deutschland werden jedes Jahr hunderttausende homöopathische Mittel "verschrieben", Vitaminspritzen gesetzt und bunte Klebebänder auf verkrampfte Muskeln getaped. Gleichzeitig nimmt die Skepsis gegenüber der Schulmedizin immer weiter zu, sodass Menschen ihre eigenen Kinder bewusst in Lebensgefahr bringen, indem sie Impfungen ablehnen.

From tuberculosis to bird flu and HIV to coronavirus, these infectious diseases share a common origin story: human interaction with animals. Otherwise known as zoonotic diseases for their passage from animals to humans, these pathogens—both pre-existing ones and those newly identified—emerge...

"Chan and Ridley write with an urgency...that inspires gripping depictions of what viruses are, how infectious-disease laboratories work and wonderfully lucid descriptions of bats. . . . They powerfully recount how dangerous pathogens can both leak from a lab and emerge in nature." (New York...
