Background:
Cundinamarca is the fifth most affected region of the country by COVID-19 in the elderly population. The objective was to determine the characteristics of the disease in this population group to establish actions that reduce the impact.

Methods:
A descriptive study of the epidemiological behavior of COVID-19 in Cundinamarca in a population aged 60 and over was carried out. Data was obtained from routine surveillance of the severe acute respiratory infection event from March until August, 2020. Descriptive statistics of sociodemographic and clinical characteristics were performed.

Results:
A total of 2,241 cases were reported, with an incidence rate of 515.8 cases per 100,000 inhabitants; 332 people died with a mortality rate of 76.4 cases per 100,000 inhabitants and a fatality rate of 14.8%. The proportion of hospitalization and deaths increased starting at the eighth decade of life. 51.9% presented cough, 33.5%, fever and 24.3%, respiratory distress; 20.9% were asymptomatic. 39.4% had arterial hypertension, 17.8%, kidney disease, and 17.1%, diabetes mellitus. According to the clinical outcome, 32.2% were in general hospitalization, and 3.9% in the intensive care unit. Symptoms and comorbidities increased in percentages in hospitalized and deceased cases as compared to outpatients.

Conclusions:
The fatality for the 60 to 70 years of age is six times higher in the department as compared to the national behavior, the mortality rate is six times higher than that of the department. Increases in hospitalization and fatalities suggests than age, gender, and comorbidities may be factors related to clinical complications or death, findings which are consistent with data reported in other countries that validate the establishment of actions of prevention and control focused on vulnerable populations. Based on this descriptive research, analytical studies are recommended to establish the risk factors associated with fatal outcomes.
