The SARS-CoV-2 vaccination plan development in Colombia, set to begin in February 2021, included a comprehensive assessment of the spread to set population priorities in rank-ordered phases. In Phase 3 of the plan, populations between 16 and 59 years with a set of specific comorbidities will be vaccinated. Our study's objective is to evaluate the comorbidities incidence in the probability of survival of a patient in the country to assess patients at most risk if infected and assist in the assignation of this phase. In this study, multivariate Cox regression and Kaplan-Meier curves were performed to determine risk predictors of mortality for 610 reports of up to 15-day decay non-survivor patients in Colombia. After implementation, higher hazard ratios were associated with diabetes. Kaplan-Meier curves indicate that patients with diabetes that have an older age and hypertension are at a higher risk of earlier death.
