Inequalities in covid-19 inequalities research: Who had the capacity to respond?
-
1Between January 2020 and 23 April 2021, 9,355 scientific articles were published on covid-19-associated inequalities worldwide, and 140 countries contributed to at least one article.
-
2The emerging research field of covid-19 inequalities has been highly collaborative, although inequitable research practices exist within these collaborations, between countries, between country income groups and between world regions.
-
3North America and the European and Central Asian region have contributed most to this research in terms of world regions. The Middle Eastern and North African region is the third largest regional producer of covid-19 inequalities research, and has significantly increased its scientific productivity in comparison to the research field of (pre-covid-19) global health inequalities.
-
4Three main clusters of collaboration were identified within this research field: one that contained Anglo-Saxon, Asian and African countries, a second one mainly comprising European countries and Chile, and a third one mainly made up of four Latin American countries: Colombia, Brazil, Mexico and Argentina.
-
5Prior to the pandemic, evidence demonstrated that inequalities existed in the global capacity to produce research on health inequalities, which has likely reduced many countries’ scientific capacity and preparedness to respond to the covid-19 pandemic.
-
6To ensure proactive preparedness for future crises and effective strategies to tackle growing health inequalities, investment in related research capacities must be a priority in all countries.

Map of the world showing the different degrees of collaborations from different countries in covid-19 inequalities research. The colour of each country reflects the number of articles produced in collaboration with other countries (increasing from red to blue).
The colour of the connections encodes the number of articles in which the two linked countries appear (increasing from yellow to red, with the green connection indicating the ´highest producing´ research cluster).
