About the Author

Paul Ewald is a renowned evolutionary biologist and professor emeritus at the University of Louisville, where he has spent decades exploring the intricate dynamics between pathogens and their hosts. With a PhD from the University of Washington, Ewald's groundbreaking research challenges traditional views on infectious diseases, proposing that many chronic conditions stem from persistent microbial infections. His seminal work, Plague Time: The New Germ Theory of Disease, revolutionized public health perspectives by advocating for evolutionary approaches to disease prevention and treatment. Ewald's insights have influenced global epidemiology, emphasizing how human behaviors and medical practices can drive pathogen evolution. A prolific writer and speaker, he continues to advocate for evidence-based strategies to combat emerging threats like antibiotic resistance and viral pandemics.
