Abstract Purpose Purpose of this study was to assess clinical characteristics and risk factors for mortality of patients with COVID-19 from Mexico, given that currently is in active community transmission. Methods Multivariate logistic regression model and Kaplan-Meier survival curves were fitted to study odds of death of characteristics and comorbidities in COVID-19 patients in Mexico. Results Age, sex and the most frequent comorbidities diabetes, obesity and hypertension were significantly associated to risk of death by COVID-19 (P<0.0001). Smoking habits was not identified as risk factor for death. Less frequent comorbidities such as chronic obstructive pulmonary disease, chronic kidney disease and immunosuppressed patients also showed a significant risk for death (P<0.0001). Hospitalized and pneumonia patients had serious risks for mortality (P<0.0001) and more attention to specific conditions might be considered during clinical admission. Conclusions More vulnerable positive patient is depicted by a male patient, older that 41 years, that increase their hazard risk with more prevalent comorbidities diabetes, obesity and hypertension.
