    There is every reason to believe that, within a few weeks of its onset, the infection was universally present in the nose and throat of the people, disseminated by mouth spray given off on talking by innumerable carriers and, in addition, by the coughing and sneezing of the sick. Susceptibility was very general, though it varied greatly in degree. Among those who escaped well marked sickness there are few who could not recall having had an occluded or running nose, or a raw feeling in the throat, or a cough, or aches and pains, at some time during the period of the prevalence of the disease, these probably representing the price such persons paid for their immunization." - Dr. Bernard Fantus In many ways, it is hard for modern people living in First World countries to conceive of a pandemic sweeping around the world and killing millions of people, and it is even harder to believe that something as common as influenza could cause such widespread illness and death. Although the flu still takes hundreds of lives each year, most of those lost are very young or old or ill with something else that had already weakened them. In fact, most people contract influenza at least once, and many suffer from the flu several times in their lives and survive it with a minimum amount of medical attention. In 1918, the world was still in the throes of the Great War, the deadliest conflict in human history at that point, but while World War I would be a catastrophic war surpassed only by World War II, an unprecedented influenza outbreak that same year inflicted casualties that would make both wars pale in comparison. An illness, or more likely a collection of illnesses, Spanish influenza quickly spread across the world and may have killed upwards of 100 million people, decimating populations across developed nations and possibly wiping out as much as 5% of the world’s population. If anything, the ongoing war and the censorship maintained by the countries fighting it may have resulted in the actual toll of the outbreak being underestimated based on the way soldiers’ deaths were categorized. World War I may have distracted people about the unprecedented nature of the outbreak, but the most alarming aspect of the outbreak in 1918 was the indiscriminate nature in which the scourge attacked young and old, healthy and unhealthy, and rich and poor alike. In fact, the popular name for the outbreak was a reference to the fact that Spain’s own king was stricken with the disease. While he and President Woodrow Wilson ended up surviving it, former First Lady Rose Cleveland did not. The staggering number of fatalities, and the way in which seemingly anybody could suffer during the outbreak, taught people in the early 20th century that regardless of the tremendous strides made by technology, and no matter how stalemated the war was, nobody was safe from nature itself. Of course, it also demonstrated how much more work could be done to prevent similar occurrences. The 1918 pandemic was neither the first nor the last outbreak of the flu, but it was by far the worst, and it forever changed the face of medicine and public health care in both North America and Europe. The 1918 Spanish Flu Pandemic: The History and Legacy of the World’s Deadliest Outbreak chronicles the devastating disease and the damage it wrought across the globe.

    Forty-five million called him emperor, and he commanded a nation that was the richest, most cultured, and advanced on earth. No army could stand against his impeccably trained, brilliantly led forces, and his continued sweep across Europe seemed inevitable. Early that year, bolstered by his successes, Napoleon turned his attentions toward Moscow, helming the largest invasion in human history. Surely, Tsar Alexander’s outnumbered troops would crumble against this mighty force. But another powerful and ancient enemy awaited Napoleon’s men in the Russian steppes. Virulent and swift, this microscopic foe would bring the emperor to his knees. Even as the Russians retreated before him in disarray, Napoleon found his army disappearing, his frantic doctors powerless to explain what had struck down a hundred thousand soldiers. The emperor’s vaunted military brilliance suddenly seemed useless, and when the Russians put their own occupied capital to the torch, the campaign became a desperate race through the frozen landscape as troops continued to die by the thousands. Through it all, with tragic heroism, Napoleon’s disease-ravaged, freezing, starving men somehow rallied, again and again, to cries of “Vive l’Empereur!”Yet Talty’s sweeping tale takes us far beyond the doomed heroics and bloody clashes of the battlefield. The Illustrious Dead delves deep into the origins of the pathogen that finally ended the mighty emperor’s dreams of world conquest and exposes this “war plague’s” hidden role throughout history. A tale of two unstoppable forces meeting on the road to Moscow in an epic clash of killer microbe and peerless army, The Illustrious Dead is a historical whodunit in which a million lives hang in the balance.

    At the start of the first series, Percy is introduced as a troubled twelve-year-old diagnosed with both ADHD and dyslexia. After getting attacked at school, he is escorted to Camp Half-Blood, a secret camp built to train and protect Greek demigods. At camp, Percy learns that his father is Poseidon, the god of the sea, and is thus a child mentioned in the Great Prophecy, a prophecy that was given by the Oracle seventy years ago. Throughout the series, Percy embarks on several quests to save his friends and the Olympian gods of Mount Olympus.

    In Missing Microbes, Dr. Martin Blaser invites us into the wilds of the human microbiome where for hundreds of thousands of years bacterial and human cells have existed in a peaceful symbiosis that is responsible for the health and equilibrium of our body. Now, this invisible eden is being irrevocably damaged by some of our most revered medical advances—antibiotics—threatening the extinction of our irreplaceable microbes with terrible health consequences. Taking us into both the lab and deep into the fields where these troubling effects can be witnessed firsthand, Blaser not only provides cutting edge evidence for the adverse effects of antibiotics, he tells us what we can do to avoid even more catastrophic health problems in the future. http://us.macmillan.com/missingmicrob...

    The first small cities formed not only the cradle of civilization, but the spawning ground for the earliest viral epidemics, the first opportunity for viruses to find a home in the human herd. This is a story of fear and ignorance, as everything from demons and the wrath of the gods to minority groups have been blamed for epidemics from smallpox to yellow fever to AIDS. It is a story of grief and heartbreak, as hundreds of thousands, sometimes millions, are wiped out in a single year. And it is a story of great bravery and sacrifice, as doctors and nurses put themselves in harm's way to combat yellow fever in Memphis and Ebola in Zaire, and as researchers risk their own lives to test theories of vaccines and the transmission of disease. Now, in Viruses, Plagues, and History, Michael B. A. Oldstone tells all these stories as he illuminates the history of the devastating diseases that have tormented humanity.Oldstone focuses his tale on a few of the most famous viruses humanity has battled, beginning with some we have effectively defeated, such as smallpox, polio, and measles. Nearly 300 million people were killed by smallpox in this century alone -- more than were killed in all the wars of the twentieth century combined. The author presents a vivid account of the long campaign against the virus, the insightful work of Edward Jenner, who created the smallpox vaccine from cowpox virus in 1796, and the monumental efforts of D. A. Henderson and an army of W.H.O. health care workers to finally eradicate smallpox. The smallpox virus remains the only organism that we have deliberately pushed to complete extinction in the wild.Oldstone then describes the fascinating viruses that have captured headlines in more recent years: Ebola and other hemorrhagic fevers, which literally turn their victims' organs to a bloody pulp; the Hantavirus outbreaks in the southwestern United States and elsewhere; mad cow disease, a frightening illness made worse by government mishandling and secrecy; and, of course, AIDS, often called the plague of our time. And he tells us of the many scientists watching and waiting even now for the next great plague, monitoring influenza strains to see whether the deadly variant from 1918 -- a viral strain that killed over 20 million people in 1918-1919, more than twice the military and civilian casualties of the First World War -- will make a comeback.Viruses have enormous power. They have wiped out cities, brought down dynasties, and helped destroy civilizations. But, as Michael Oldstone reveals, scientific research has given us the power to tame many of these viruses as well. Viruses, Plagues, and History shows us the panorama of humanity's long-standing conflict with our unseen viral enemies, from our successes to our continuing struggles. Oldstone's book is a vivid history of a fascinating field, and a highly reliable dispatch from a worker on the frontiers of this ongoing campaign.

    In The Beautiful Cure, leading immunologist Professor Daniel Davis describes the scientific quest to understand how it works – and how it is affected by stress, sleep, age and our state of mind – and explains how this knowledge is now unlocking a revolutionary new approach to medicine and well-being.The body's ability to fight disease and heal itself is one of the great mysteries and marvels of nature. But within the last few years painstaking research has resulted in major advances in our understanding of this breathtakingly beautiful inner world: a vast and intricate network of specialist cells, regulatory proteins and dedicated genes that are continually protecting our bodies. Far more powerful than any medicine ever invented, it also plays a crucial role in our daily lives. Already we have found ways to harness these natural defences to create breakthrough drugs and so-called immunotherapies that help us fight cancer, diabetes, arthritis and many age-related diseases, and we are starting to understand whether or not activities such as mindfulness might play a role in enhancing our physical resilience.Written by an expert at the forefront of this adventure, The Beautiful Cure tells a dramatic story of detective work and discovery, of puzzles solved and of the mysteries that remain, of lives sacrificed and saved, introducing the reader to this revelatory new understanding of the human body and what it takes to be healthy.
