Infectious diseases constitute a major health problem both in developed and developing countries. Old and emerging infectious diseases contribute substantially to morbidity and mortality worldwide. For this reason, the society invests considerably on infectious diseases research, in order to achieve scientific progress and develop new therapeutic interventions.
The research productivity by various world regions has been studied for several biomedical fields. In general, the USA and Western Europe are the leaders of global biomedical research, although their relative contribution varies for different fields of research . Several studies have focused on the scientific production of European Union's countries, in various biomedical fields, including Infectious Diseases . However, the literature lacks studies estimating the quantity and quality of worldwide research production in Infectious Diseases. The purpose of our study was to evaluate the contribution of different world regions in scientific research in the field of Infectious Diseases.
