Irving A. Cohen, MD, MPH has dedicated his medical career to the prevention of disease, focusing on early interventions to prevent more serious disease outcomes later. Recognizing that medicine focused on treating illness that was often preventable, he trained in Preventive Medicine and Public Health at Johns Hopkins University, and served as Chief Resident of Preventive Medicine. He has been Board-Certified in that field for 35 years and is a Fellow of the American College of Preventive Medicine. Dr. Cohen served in many settings and has held faculty appointments at prestigious institutions. He developed programs and has written books concerning recovery from addiction, overweight, and diabetes. He has presented at scientific forums in the U.S. and Canada. He recognized that the unequal risk of serious illness and death from Covid-19 was modifiable. He wrote this book to tell the public that they are not helpless, even when increased risk is attributed to race or age.
