Countries have traditionally been split into two major groups: developed or industrialized (“the North”) and developing or underdeveloped (“the South”). Several authors and organizations have challenged this classification to recognize countries that have reached an intermediate stage of social and economic development. As proposed by Morel and collaborators in 2005, the concept of Innovative Developing Countries (IDCs) defines a group of nations with impactful scientific programs. Here, IDCs are reexamined by a variety of metrics to highlight their role in health innovation through research and development (R&D) programs on neglected tropical diseases (NTDs) that also positively impact epidemic preparedness.
