INTRODUCTION As a result of COVID-19, many hospitals underwent a conversion for the care for this disease. OBJECTIVE To analyze COVID-19 hospital epidemiological behavior from March to August 2020. METHODS Through a series of cases, COVID-19 epidemiological behavior at the hospital was analyzed, for which simple case rates, percentages and incidence of COVID-19 per 100 hospital discharges were estimated. RESULTS Out of 491 subjects who tested positive for SARS-CoV-2, 156 (31.7 %) were hospitalized for clinical data of moderate to severe disease. Average age was 59.1 years; 121 cases (75 %) were discharged due to improvement, and 32 (20.5 %), due to death. Average age of those who died was 69.7 years, and the most affected age group was 60 to 80 years (45.4 %). Calculated lethality was 20.5 per 100 hospital discharges, while that calculated taking into account positive patients (outpatients and hospitalized patients) was 6.5. CONCLUSIONS COVID-19 epidemiological behavior was similar to that described in other studies; however, lethality and mortality are above national average. The analysis of this and of the factors that favored it in our population is pending.
