Materials and methods:  A retrospective cohort study in the Colombian population between March 6 to July 8, 2020, with the data reported to the National Institute of Health. Survival analysis was performed considering the real-time PCR results, died or recovered, the onset of symptoms until the date of death, or the final time of the cohort. The actuarial variation and Long-Rank test were applied for survival. Risk factors were determined by Cox regression.  Results:  The overall survival rate was 100%, 98%, 97%, and 95% for day 1, 10, 20 and 30, respectively. Differences were found in survival in age, sex, region, and hospitaliza tion time spending (p &lt;0.01), the 30-day survival rate was 96% and 95% for females and males, respectively. The region with the highest survival was Antioquia with 99% and the lower Barranquilla with 93%. The age group with the lowest survival was &#8805;80 years of age with 60%, and being hospitalized represented a survival rate of 68%.  Conclusions: This study is one of the first to estimate survival in the Colombian population diagnosed with COVID-19.]]></p></abstract>

Materiales y métodos: Estudio de cohorte retrospectivo en población colombiana entre el 6 de marzo al 8 de julio de 2020, con los datos reportados al Instituto Nacional de Salud. El análisis de supervivencia se realizó considerando los resultados de la PCR en tiempo real, fallecido o recuperado, el inicio de los síntomas hasta la fecha del fallecimiento o el momento final de la cohorte. Para la supervivencia se aplicó la variación actuarial y la prueba de rango largo. Los factores de riesgo se determinaron mediante regresión de Cox.  Resultados: La tasa de supervivencia general fue del 100%, 98%, 97% y 95% para los días 1, 10, 20 y 30, respectivamente. Se encontraron diferencias en la su pervivencia en cuanto a edad, sexo, región y tiempo de hospitalización (p &lt;0,01), la tasa de supervivencia a 30 días fue del 96% y 95% para mujeres y hombres, respectivamente. La región con mayor supervivencia fue Antioquia con 99% y la Baja Barranquilla con 93%. El grupo de edad con menor supervivencia fue el &#8805;80 años con 60%, y la hospitalización representó una tasa de supervivencia del 68%.
