Dear all, I thank you for your efforts. I proposed a new Wikidata property for co-morbidities. The proposal is available at https://www.wikidata.org/wiki/Wikidata:Property_proposal/Comorbidity. I ask if you can provide your opinions about it. I also ask if this property can be merged with risk factor property. Yours Sincerely, Houcemeddine Turki
