Since the end of 2019, we have been facing a global epidemic related to the coronavirus causing COVID-19. This epidemic raises many medical and social issues and requires the mobilization of the research community to help health professionals and decision-makers make informed decisions to protect the health of the population.


CARTaGENE has been identified as an important resource for advancing research on this virus and the associated disease, COVID-19. Your commitment to health research becomes even more important as you now have the opportunity to make a difference in the fight against the coronavirus by participating in this study.



Purpose of the study

This study aims to understand, among other things, the development of COVID-19 and the severity of the symptoms that affect people with it, as well as the risk and protective factors for people without it. The data that will be generated will be used to better understand the coronavirus epidemic and the medical and scientific aspects of COVID-19. The data will also help decision-makers to organize the health system and to develop reopening strategies.
