  This paper presents a project, named VIDAR-19, able to extract automatically
diseases from the CORD-19 dataset, and also diseases which might be considered
as risk factors. The project relies on the ICD-11 classification of diseases
maintained by the WHO. This nomenclature is used as a data source of the
extraction mechanism, and also as the repository for the results. Developed for
the COVID-19, the project has the ability to extract diseases at risk and to
calculate relevant indicators. The outcome of the project is presented in a
dashboard which enables the user to explore graphically diseases at risk which
are put back in the classification hierarchy. Beyond the COVID-19, VIDAR has
much broader applications and might be directly used for any corpus dealing
with other pathologies.
