Revisiting the concept of Innovative Developing Countries (IDCs) for its relevance to health innovation and neglected tropical diseases and for the prevention and control of epidemics.

Different techniques can be used to evaluate and measure innovative performance of countries. Country rankings published by traditional indexes, such as the Bloomberg Innovation Index (BII) and the Global Innovation Index (GII), only include high income economies among the top 20 performers. This is in sharp contrast to our approach, which identified 8-9 IDCs among the first 25 with China occupying the top position. Through an analysis of the pros and cons of the different methodologies, the IDC concept challenges more conventional approaches to address and estimate the innovative capacity of countries.
