The Facts and Fears About the Ebola Virus

            The Ebola virus was first identified in remote villages in Central Africa in Sudan and Zaire nearly forty years ago in 19 The Ebola virus was first identified in remote villages in Central Africa in Sudan and Zaire nearly forty years ago in 1976.  Between 1976 and 2012, the World Health Organization (WHO) documented 2,387 cases (restrained to Africa only) and about half have died. Of course, in the last two years that number has now climbed to over 10,000 cases. On October 23, WHO convened a crisis meeting to figure out how get the two vaccines now in development, through clinical trials, and developed at an “accelerated pace.”

            An epidemic involves a widespread outbreak of an infectious disease in one community all in a particular time period. A pandemic, on the other hand, means (from the Greek) “pertaining to all people.” A pandemic, then, is an outbreak in a wide area or global sphere. Pandemics in history have included notorious outbreaks, including the Black Death and Bubonic Plagues that devastated Europe in the 1300s and 1800s. There have been extensive outbreaks of Cholera and Influenza. The Spanish Flu was responsible for millions of deaths in 1918, 1919 and 1920. (Read local author, and past library trustee, Patti Fanning’s account in “Influenza and Inequality,” published in 2010 in which she discusses how that epidemic affected our Norwood community.) In just three years, the Spanish Flu affected 500 million people worldwide and killed 50-100 million of them.

According to the World Health Organization (WHO) website, Ebola is deadliest in countries “lacking human and infrastructural resources”.  In other words, Ebola's death rate will be highest in countries with inadequate healthcare and systems in place to contain the virus. There have been scientific books written about the Ebola virus since the late 1970s.  However, it was in the 1990s that the Ebola virus became more of a household word.  Laurie Garrett, in the non-fiction book, “The Coming Plague” (1995) based her book on her own research of both scientific material, interviews, and popular literature.  One of her premises is that an overuse of antibiotics has produced drug-resistance and viruses and infections are mutating.  In addition, funding for necessary research is diminishing.  Diseases, then, will fill this void and spread in this era of woes – recessions, global warming, and our world that was recklessly polluted in the 20th century.

            Two years later, in 1995, author Richard Preston wrote an alarming thriller – a book of non-fiction titled “The Hot Zone.”  The Ebola scare hit the literary scene when Preston wrote an article for the New Yorker in 1992: “Crisis in the Hot Zone.” In the "Hot Zone, he included the history of both the Ebola and Marburg viruses and produced an even more frightening work by including stories about the deaths of monkeys in a research facility in Reston, Virginia. Of interest is the news that producer Ridley Scott has just announced a television series based upon the incidents in Preston's book.   A few years after the dramatic “Hot Zone”, Joseph McCormick and Susan Fisher Hoch, both researchers with the CDC, the Center for Disease Control, in Atlanta wrote “Level 4 - Virus Hunters of the CDC."   Trained in epidemiology and virology, the married couple has studied Ebola, AIDS, Lassa fever, Legionnaire’s disease and hepatitis. Their thrilling and disturbing case studies about these microscopic pathogens and how they are studies are included with biographical information in their book.

            The first decade of the 21st Century produced many more books published on epidemics, their unexpected spread, and fear and dread that they have induced. They began in 2001 with “Killer Germs,” followed six years later in “The Little Book of Pandemics."  Both were written by Peter Moore, a British Ph.D.  Moore’s books are filled with facts – some alarming ones– about the rise of the numbers of infectious diseases, and the fight to stop them - not necessarily the deaths from them. Moore covers Rocky Mountain fever, West Nile, SARS among the more well-known – leprosy, meningitis, smallpox and influenza. David Zimmerman, author of “Killer Germs” (2003) included bioterrorism, flesh-eating bacteria, and future super germs in his account of “bacteria, protozoa, fungi, and worms” that threaten our health.  Dorothy Crawford, in “Deadly Companions” (2007) describes how microbes have shaped human history.  Carl Zimmer explains in “A Planet of Viruses” (2013), a readable book of 11 short essays, that our world ‘is crawling’ with viruses and always has been. In “Deadly Outbreaks” (2013), Alexandra Levitt explains that the danger from drug-resistant bacteria and the steps that medical investigators are taking to overcome the mysteries of emerging diseases and unexplained deaths. 

            Interestingly, Philip Alcabes, author of “Dread - How Fear and Fantasy Have Fueled Epidemics from Black Death to Avian Flu” (2009), explains that we have a much higher likelihood of dying in many other ways than dying of a contagious disease.  The drama and fascination of epidemics and pandemics make great subjects for movies and emergency-room trauma series. Yet, the anxiety and fear do not meet the risk. That said, even the most level-headed of us can have difficulties sorting out fact from fiction is our age of round-the-clock sensational media coverage.

                 More alarming are some of the more recent books by Peter Piot, Nathan Wolfe, and David Quammen. Piot, as a young doctor, was one of the first researchers of the Ebola virus in the 1970s.  Only a decade later, he was stalking the AIDS virus throughout Africa and across the globe. His book, “No Time to Lose” (2012) describes his life – one ‘in pursuit of deadly viruses.”  Stanford biologist Wolfe’s book, “The Viral Storm” (2011) attests that it is our life in this modern age that makes us vulnerable.  David Quammen has written two books in just the past two years. His most recent, “Ebola” will be published this month.  That book is a more comprehensive analysis of the Ebola virus, a discussion he included in “Spillover” - a 2012 book that explores the connection of animal-borne diseases that “spillover” from the animal world to humans such as SARS, Ebola and AIDS.

            Reading these books can be unsettling and frightening.  However, it is critically important to educate rather than overreact, to enlighten rather than fear. All of these books are available through the Minuteman Library Network and our library catalog. Several are available in audio, large print and electronic format. Call the library if you need help requesting them.
