The international public health community is in mourning following the death of Dr David Nabarro, a towering figure in global medicine, humanitarian crisis response, and sustainable development. Dr Nabarro passed away peacefully at his home on Friday, July 25, 2025, at the age of 75. Over a distinguished career spanning decades, he served at the highest echelons of the World Health Organization (WHO) and the United Nations, leaving an indelible mark on how the world prepares for pandemics, addresses malnutrition, combats malaria, and responds to humanitarian emergencies.

News of his passing has prompted an overwhelming global response. Colleagues, international leaders, and organizations he helped shape have shared tributes highlighting his lifelong dedication to the world’s most disadvantaged populations. His contributions earned him widespread respect, culminating in his knighthood by King Charles III in 2023 for services to global health.

A Life Dedicated to Public Health and Global Equity

Dr Nabarro’s career was defined by an extraordinary versatility and a tireless commitment to multilateral cooperation. He "wore many hats," seamlessly transitioning between roles in infectious disease control, food security, climate change adaptation, and high-level diplomatic crisis management.

At the WHO, he was frequently deployed to the front lines of the world’s most severe health emergencies. Whether coordinating the global response to avian influenza, managing the terrifying resurgence of Ebola in West Africa, or advising international bodies on the existential threats posed by climate change, Dr Nabarro brought a unique blend of strategic clarity, operational skill, and deep human compassion.

Beyond his administrative and diplomatic achievements, he was renowned as a mentor. Countless public health professionals working across the globe today trace their career development back to his patient guidance, visionary thinking, and unwavering support.

The leadership of the World Health Organization led the global expressions of grief. WHO Director-General Dr Tedros Adhanom Ghebreyesus issued a deeply personal and professional statement reflecting on the loss of a trusted colleague and friend.

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 4SD Foundation (Skills Systems and Synergies for Sustainable Development)—an organization Dr Nabarro co-founded in Switzerland in 2018 alongside Florence Lasbennes to train and mentor leaders in sustainable development—released a formal announcement titled "A Difficult Announcement."

The foundation’s statement underscored his enduring personal warmth alongside his professional legacy: "David’s generosity and unwavering commitment to improve the lives of others will be sorely missed.

On July 30, the Nabarro family released an additional statement expressing their gratitude: "We are deeply grateful for the outpouring of tributes to David, and for the kindness to all who mourn his passing.
