comorbidity (noun) 

Morbidity (mor-BIH-dih-tee) refers to having a disease or medical condition. Comorbidity (koh-mor-BIH-dih-tee) refers to the presence of two or more diseases or medical conditions in the same patient. As I used it in today’s quiz: “What percent of people whose deaths were attributed to COVID-19 had pre-existing comorbidities?”
