Book excerpt: New York Times bestselling author and expert in epidemiology Dr. Michael Savage explains the origins of viruses and their impact on the U.S. With new and resurgent diseases resulting from unregulated immigration and a politicized public health system, Michael Savage sees the need for some changes - starting with the President and the Center for Disease Control telling us the truth. Savage makes his case for the government to enforce travel bans, the use of quarantines and the importance of proper border screenings. However, this is not a cure or treatment for any of these diseases. With Zika virus, tuberculosis, hepatitis, Enterovirus 68 and other new disease threats emerging across the U.S., Savage will explain ways to fortify your immune system and defend against these and other diseases. Drawing from his extensive training, Dr. Savage examines the benefits of using specific nutrients to boost the human immune system which, in turn, increases the odds of surviving a viral infection as well as preventing other diseases. Based on his knowledge of the politics of medicine being played by the Obama mandarins and his Ph.D. in Epidemiology and Nutrition from the University of California, Berkley, Dr. Savage presents solid information to protect your health. Whether you want to defend your body against deadly diseases, boost your immunity, or learn more about the government's impact on reemerging and imported diseases, Diseases Without Borders is your source for informative, helpful, and potentially life-saving advice.
