Abstract
At the Kyushu-Okinawa Group of Eight summit in 2000, Japan announced the Okinawa Infectious Diseases Initiative (IDI) and pledged to spend US$3 billion over a five year period to combat infectious and parasitic diseases in developing countries. The IDI has exceeded expectations, spending more than US$4 billion over four years. The IDI is a unique initiative with its own philosophical basis and specifically tailored interventions and measures that helped to initiate worldwide political and financial commitments in the fight against infectious diseases. Notably, it promoted partnerships among stakeholders and emphasized comprehensive and inter-sectoral approaches (i.e. coordination and collaboration between health and other sectors). It helped to create a new vision of what is possible in the global effort against communicable diseases and has been instrumental in shaping the changing environments of development assistance, poverty reduction and other trends to reduce the impact of infectious and parasitic diseases.
