The global health community is in mourning following the passing of Dr. David Nabarro, a transformative figure whose career spanned decades of service in humanitarian crisis response, infectious disease control, and sustainable development. Dr. Nabarro passed away at his home on Friday, 25 July 2025, at the age of 75. A man of immense intellect, compassion, and relentless energy, Dr. Nabarro was widely regarded as a champion of equity and a mentor to generations of public health professionals worldwide.
The news of his death has prompted an outpouring of tributes from the highest levels of international organizations, reflecting a legacy that touched nearly every major global health challenge of the early 21st century.
WHO Director-General Dr. Tedros Adhanom Ghebreyesus expressed his profound grief in an official statement, describing the loss of his friend and colleague as a devastating blow. “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.”
Dr. Nabarro’s career was defined by a unique ability to bridge the gap between complex policy and grassroots action. He possessed an uncanny capacity to navigate diverse sectors—from medicine and nutrition to climate change—with a singular focus on the needs of the most disadvantaged populations.
His relationship with the World Health Organization began in earnest during a pivotal period between 1999 and 2005. During these years, he served in senior leadership roles, beginning as the Executive Director responsible for the Roll Back Malaria Project, an initiative that sought to dramatically reduce the burden of the disease in high-risk regions. He later moved into the Office of the Director-General before being appointed as the Director-General’s Special Representative for Health Action in Crises. In this capacity, he became a central figure in coordinating the international response to medical emergencies, setting a standard for how global institutions should operate under pressure.
In 2005, Dr. Nabarro transitioned to the United Nations, where his portfolio expanded to address some of the most daunting systemic challenges of the modern era. As the UN System Senior Coordinator for Avian and Pandemic Influenza from 2005 to 2014, he played a critical role in preparing the international community for the threat of emerging viruses. During this same period, he also served as the UN Secretary-General’s Special Representative for Food Security and Nutrition (2008–2014) and as the Coordinator of the Movement for Scaling Up Nutrition, where his work as an Assistant Secretary-General helped elevate the importance of proper nourishment in global development agendas.
His reputation for steady leadership during times of intense panic and crisis was cemented during the 2014–2015 West Africa Ebola outbreak, where he served as the UN Secretary-General’s Special Envoy for the response. Later, his strategic acumen was applied to the 2030 Agenda for Sustainable Development and Climate Change, serving as a Special Adviser at the Under-Secretary-General level.
Dr. Nabarro’s influence extended far beyond institutional borders. In 2015, he was tapped by the WHO Director-General to chair an expert group tasked with reforming the organization’s work on outbreaks and emergencies—a foundational effort that aimed to make global health systems more resilient in the face of future pandemics. His contributions were formally recognized in 2018 when he was awarded the prestigious World Food Prize for his leadership on nutrition, a testament to his life’s work in ensuring that food security remained a central pillar of international policy.
In his later years, Dr. Nabarro continued to innovate and mentor. From mid-2019 until 2025, he served as Co-Director and Chair of Global Health at the Institute of Global Health Innovation at Imperial College, London. Driven by a desire to foster new talent, he co-founded the 4SD Foundation (Skills Systems and Synergies for Sustainable Development) in 2018 with Florence Lasbennes. Through 4SD, he focused on training and mentoring the next generation of leaders, teaching them how to drive sustainable development through systemic change.
His commitment to the environment and the health of the planet was equally profound. Between 2018 and 2025, he curated the Food Systems Dialogues, an essential contribution to the transformation of global food systems. He also played a vital role in the preparations for the UN’s September 2019 Climate Action Summit and served as a co-facilitator for the coalition advancing the Nature-Based Solutions workstream. In November 2020, he co-chaired the forum on Climate Change and Health at the World Innovation Summit for Health, further bridging the gap between ecological stability and human well-being.
When the COVID-19 pandemic paralyzed the world in early 2020, Dr. Nabarro was once again called upon to provide steady, evidence-based guidance. In March 2020, he was appointed as the Special Envoy of the WHO Director-General on COVID-19, a position he held with distinction until his death. Under his strategic guidance, the 4SD Foundation led the Summit Dialogues that informed the 2021 UN Food Systems Summit, an event that birthed a network of National Convenors who continue to work on transforming food systems today.
Even as he managed global crises, Dr. Nabarro remained deeply engaged with the unfolding geopolitical realities. When the war in Ukraine began, he joined the UN Secretary-General’s Food, Energy and Finance crisis response group, co-leading the Food Workstream to mitigate the impact of the conflict on global food supply chains. His lifelong service was recognized in 2023 when King Charles III conferred a knighthood upon him for his monumental contributions to global health.
The 4SD Foundation, in a statement titled “A Difficult Announcement,” confirmed his passing and noted that he died at his home. The statement highlighted not just his professional accomplishments, but his character: “David’s generosity and unwavering commitment to improve the lives of others will be sorely missed. He leaves behind his beloved wife, Flo, his children, Tom, Ollie, Polly, Josie, Lucas and seven grandchildren. The family is comforted by the support and compassion extended to them as they navigate this difficult time.”
On 30 July, the family released a follow-up statement expressing their gratitude for the global response to his passing. “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 Dr. Nabarro is scheduled for Monday, 4 August, with close family members in attendance. In the weeks following, the organization and the family plan to hold a series of memorial services, allowing the many colleagues, mentees, and friends whose lives were touched by his work to pay their respects. For those wishing to share memories or offer condolences, a dedicated memorial web page has been established, while further updates regarding formal memorial arrangements are being coordinated through the 4SD Foundation.
