AO_SCPLOWBSTRACTC_SCPLOWUnderstanding COVID-19 and its risk factors in the Portuguese population is critical to the struggle against this infectious disease. To study the impact of multimorbidity in the population with COVID-19 infection, we performed a descriptive analysis of a dataset extracted from all reported confirmed cases of COVID-19 in Portugal until June 30, 2020. We observed a prevalence of multimorbidity in 6.77% of the 36,244 infected patients. These patients showed an increased risk of hospitalization, ICU admission, and mortality with OR 2.22 (CI 95%: 2.13-2.32) for every additional morbidity. Further studies should confirm these findings and special attention should be made on data collection, to ensure proper recording of patient comorbidities.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
