The international public health community is in mourning following the announcement that Dr. David Nabarro, a transformative figure whose career spanned decades of humanitarian crisis response, infectious disease management, and sustainable development, has passed away. Dr. Nabarro died at his home on Friday, 25 July 2025, at the age of 75. His death marks the loss of one of the world’s most versatile and dedicated champions for health equity and the rights of the most vulnerable populations across the globe.
Dr. Nabarro’s influence reached into the highest echelons of international governance, including the World Health Organization (WHO) and the United Nations, where he was instrumental in shaping global strategies for pandemic preparedness, food security, and climate change resilience. Known by colleagues not only for his intellectual rigor and strategic vision but also for his deep compassion and commitment to mentorship, Dr. Nabarro leaves behind a legacy defined by his ability to bridge the gap between complex policy and on-the-ground action.
In a poignant statement released shortly after the news broke, WHO Director-General Dr. Tedros Adhanom Ghebreyesus expressed his profound grief. "I am deeply shocked and saddened by the passing of our dear friend, colleague and WHO Envoy David Nabarro," Dr. Tedros said. "David was a great champion of global health and health equity, and a wise, generous mentor to countless individuals. His work touched and impacted so many lives across the world. On behalf of WHO, I am extending our heartfelt condolences to David’s family, friends and colleagues. Rest in peace, my dear friend. We will dearly miss your expertise, wisdom and kindness."
The breadth of Dr. Nabarro’s career was characterized by a unique ability to adapt to shifting global challenges. Whether addressing the resurgence of malaria, the specter of avian influenza, the humanitarian devastation caused by the Ebola virus in West Africa, or the unprecedented logistical challenges posed by the COVID-19 pandemic, Dr. Nabarro was consistently at the forefront of the response. His career was a testament to his belief that health is not merely a medical issue, but an intersectional challenge tied inextricably to nutrition, climate change, and the strength of social systems.
His tenure at the World Health Organization began in earnest during the late 1990s. Between 1999 and 2005, he held pivotal senior leadership positions, serving as the Executive Director for the Roll Back Malaria Project and acting as a central figure within the Office of the Director-General. During this period, he was also appointed as the Director-General’s Special Representative for Health Action in Crises, a role that underscored his reputation as a cool-headed strategist during periods of acute geopolitical and health instability.
In 2005, Dr. Nabarro transitioned to the United Nations, where his portfolio expanded to encompass some of the most critical challenges facing the global population. As the UN System Senior Coordinator for Avian and Pandemic Influenza from 2005 to 2014, he played a vital role in coordinating international responses to emerging viral threats. This work seamlessly transitioned into his focus on food security and nutrition, where he served as the UN Secretary-General’s Special Representative for the field between 2008 and 2014. During this time, he also served as the Coordinator of the Movement for Scaling Up Nutrition at the Assistant Secretary-General level, a role in which he advocated for the nutritional well-being of millions of children and families worldwide.
His leadership was perhaps most visible during the West Africa Ebola outbreak of 2014 and 2015, where he served as the UN Secretary-General’s Special Envoy, coordinating the international effort to stem the tide of the epidemic. Following this, he pivoted toward the long-term challenges of the 21st century, serving as the Special Adviser for the 2030 Agenda for Sustainable Development and Climate Change from 2016 to 2017. His expertise was further recognized when he was appointed by the WHO Director-General to chair the expert group tasked with reforming the organization’s work on outbreaks and emergencies—a reform effort that would prove essential for the years to follow.
Dr. Nabarro’s commitment to academic rigor and the training of future generations was as significant as his policy work. In 2018, he co-founded the Swiss-based 4SD Foundation (Skills Systems and Synergies for Sustainable Development) alongside Florence Lasbennes. Through this organization, he dedicated his time to mentoring leaders, fostering the skills necessary to manage complex, sustainable development systems. Simultaneously, he served as the Co-Director and Chair of Global Health at the Institute of Global Health Innovation at Imperial College, London, from 2019 until his passing.
His impact on global food systems was recognized in 2018 when he received the prestigious World Food Prize. This recognition highlighted his career-long dedication to ensuring that food systems are both nutritious and sustainable. In the years that followed, he curated the Food Systems Dialogues, which contributed significantly to the transformation of global food policies. His influence extended to the climate arena as well, where he helped prepare for the 2019 UN Climate Action Summit and facilitated the workstream on Nature-Based Solutions. Furthermore, he co-chaired the forum on Climate Change and Health at the World Innovation Summit for Health in 2020.
When the COVID-19 pandemic paralyzed the world in early 2020, Dr. Nabarro was once again called upon to provide his seasoned leadership. Appointed as the Special Envoy of the WHO Director-General on COVID-19, he served in this capacity until his final days. Under his guidance, the 4SD Foundation facilitated the Summit Dialogues that informed the 2021 UN Food Systems Summit, leading to the creation of a global network of National Convenors who continue to work on food systems transformation to this day. His resolve remained unshaken even as he took on the additional responsibility of co-leading the Food Workstream for the UN Secretary-General’s Food, Energy and Finance crisis response group following the onset of the war in Ukraine.
In recognition of his extraordinary contributions to global health, Dr. Nabarro was knighted by King Charles III in 2023. This honor reflected the immense respect in which he was held by peers, governments, and international organizations alike.
The 4SD Foundation, in their announcement titled "A Difficult Announcement," shared that Dr. Nabarro passed away at home. He is survived by his wife, Flo, his children—Tom, Ollie, Polly, Josie, and Lucas—and seven grandchildren. The foundation noted that his "generosity and unwavering commitment to improve the lives of others will be sorely missed."
Following the announcement of his death, the family expressed their gratitude for the outpouring of global support. On 30 July, they stated, "We are deeply grateful for the outpouring of tributes to David, and for the kindness to all who mourn his passing. Across the fields of international development, especially public health, food systems transformation, nutrition and crisis response, we are proud to see how his legacy will continue through so many compassionate leaders working to shift systems from within."
A small, private funeral for close family is scheduled for Monday, 4 August. In the weeks to follow, the global community is expected to organize several memorial services, providing an opportunity for the many colleagues, students, and partners whose lives were touched by his mentorship and vision to pay their final respects. For those wishing to share memories or offer condolences, a memorial web page has been established, serving as a repository for the stories and mementos of a life dedicated to the service of humanity.
