Ronnie Henry (1970–2020)
With this edition of the CDC Yellow Book, we say goodbye to several friends. Martin "Marty" Cetron, who directed the Division of Global Migration Health (DGMH) in the National Center for Emerging and Zoonotic Infectious Diseases at CDC since 1996, will retire from the Agency in spring 2023. Over the course of his distinguished career, Marty advanced the practice of global health, mentoring numerous leaders in the field of travel medicine along the way. A list of his accomplishments could easily fill their own volume and his ongoing support of the CDC Yellow Book over the years has helped ensure that this reference remains the respected resource it is. Thank you, Marty, for all you have done. With deep appreciation, we wish you fair winds and Godspeed.
We also are saying goodbye to three physician colleagues and longtime CDC Yellow Book contributors who passed away since we last published: Jay Keystone (September 2019), William Bunn (January 2021), and Karl Neumann (February 2021). We will miss them and their teaching. Their legacy endures, however, and the clinicians and public health professionals who contributed to this edition in their stead, stand on their shoulders.
And last, we remember Ronnie Henry, a dearly loved son, brother, and friend. Ronnie, who began working in medical writing, editing, and publishing in 1996, had experience in a wide range of subjects, including infectious and chronic disease, epidemiology, microbiology, pharmacology, and clinical research. He came to CDC in 2003 as an editor for Emerging Infectious Diseases, spent a year in Beijing teaching medical writing and publishing to Chinese researchers, and then worked as an editor for Preventing Chronic Disease. Ronnie joined the Travelers' Health Branch in June 2010, as a health communication specialist. He quickly became an encyclopedia of travel health information and served as technical editor for five editions of CDC Yellow Book.
Ronnie helped shape CDC's messaging around healthy international travel for over 10 years, and supported multiple emergency response efforts including Ebola, Zika, and COVID-19. An extraordinary teacher, he influenced authors throughout the agency. He continued writing "Etymologia" features for Emerging Infections Diseases long after he left the journal's staff, expanding readers' knowledge with his explanations of the origins of medical and scientific terms. Ronnie had the rare ability to write equally well for scientific and lay audiences. He was also the driving force behind the development of the "Can I Eat This?" app, which delivered accurate and actionable food and water recommendations for international travelers with a dose of Ronnie's trademark humor. The app appeared as an answer to a question on Jeopardy, which he claimed as a crowning achievement in his career.
Ronnie traveled the world with his closest friends, exploring the continents of North and South America, Europe, and Asia. He regaled colleagues with tales of his adventures abroad, including the time he ate the entire head of a large fish thinking it was customary to do so in Japan. The shocked expression of the chef and other diners told him otherwise, just a moment too late. Outwardly, Ronnie was a colorful character with many striking qualities that all who met him knew and loved: his ever-changing hair color; his passion for trivia games; his amazing cooking, fermenting, baking, and ice cream-making skills; improv comedy; his fondness for cats and cat memes; his wry wit, astonishing intellect, and eloquence; and the pleasure he took in sharing a well-made meal with good friends. Ronnie was a mainstay in DGMH and a light to everyone who knew him. At the time of his death (May 2020), Ronnie left behind many friends across CDC, and it is to his memory that this edition of the CDC Yellow Book is dedicated.
