  • GPEI stands with communities in Sudan, Afghanistan and Pakistan, amid devastating landslide, earthquake and floods
    Our thoughts and prayers are with the people of Sudan, Afghanistan and Pakistan, following the devastating landslide affected a village in the Darfur region of Sudan, an earthquake in Afghanistan, and amid the ongoing flood crisis in Pakistan.  Emergency relief efforts are continuing, to help alleviate suffering and maintain urgently-needed health assistance.
  • Tribute to Professor Tony Adams
    The Global Polio Eradication Initiative mourns the passing of Professor Tony Adams, whose leadership and dedication left an enduring mark on public health in Australia and globally.  He was a distinguished public servant, academic, and physician whose tireless work helped shape public health policy and led to major victories against infectious diseases worldwide.  As Chief Medical Officer for Australia and later Chair of the WHO Global Commission for the Certification of Poliomyelitis Eradication, Tony was instrumental in guiding efforts that have brought the world closer to a polio-free future. He chaired the Western Pacific Regional Commission for the Certification of Poliomyelitis Eradication as the Region became only the second one to be certified as polio-free; and was a member of the South-east Asia Regional Commission at the time that Region was certified polio-free.  His vision, integrity, and commitment to evidence-based action inspired countless colleagues and set a standard of excellence for generations of public health professionals, nationally, regionally and globally.  Beyond his professional achievements, Tony will be remembered for his warmth, kindness, and the joy he brought to those around him. Many recall his ready smile and the way he lifted the spirits of colleagues and friends alike.  For his work and service, Professor Adams was awarded numerous awards, including being named a Member of the Order of Australia, in 1998.  His passing is a profound loss to the global health community, but his legacy lives on in the progress made against polio and in the lives of those he influenced. We extend our deepest sympathies to his family, and we will remember him with gratitude and admiration.  More.
