Charlie Ericsson was one of the true pioneers of Travel Medicine and played a defining role in establishing and advancing the discipline internationally. Throughout his distinguished career at the University of Texas McGovern Medical School, he combined clinical excellence, scientific rigor and an unwavering commitment to education and mentorship. Generations of physicians, researchers and travel medicine professionals benefited from his wisdom, generosity and guidance.

Charlie’s impact on ISTM was profound and far-reaching. In addition to serving as President of ISTM, he was instrumental in shaping the Society during its formative years and helping build the strong, collaborative international community that exists today. His contributions to infectious diseases, travelers’ diarrhea and international collaborative research — particularly in Mexico — earned him worldwide recognition and respect. Yet those who knew him personally will remember not only his academic accomplishments, but also his warmth, humility, collegiality and genuine kindness.

As noted by Professor Annelies Wilder-Smith, “Charlie’s leadership helped shape Travel Medicine into the vibrant and globally connected field it is today. On a personal level, he was consistently generous, encouraging and supportive, and I will always remain grateful for his kindness and mentorship.”

Charlie’s legacy extends far beyond any one role or accomplishment. His vision, leadership, mentorship and dedication helped define the field of Travel Medicine and inspired countless individuals across the world. The impact of his work — and the community he helped build through ISTM — will continue for generations to come.

On behalf of ISTM, we extend our heartfelt condolences to Charlie’s wife Joyce, his family, friends, colleagues and all those whose lives and careers he touched.
