Objetivo: Analizar el comportamiento epidemiológico hospitalario de COVID-19 entre marzo y agosto de 2020.  Métodos: En una serie de casos se analizó el comportamiento epidemiológico de COVID-19 en un hospital de tercer nivel, para lo cual se estimaron frecuencias simples de casos, porcentajes e incidencia por cada 100 egresos hospitalarios.  Resultados: De 491 sujetos con prueba positiva para SARS-CoV-2, 156 (31.7 %) fueron hospitalizados por datos clínicos de enfermedad moderada a grave. La edad promedio fue de 59.1 años; 121 casos (75 %) egresaron por mejoría y 32 (20.5 %), por defunción. El promedio de edad de quienes fallecieron fue de 69.7 años y el grupo etario más afectado fue el de 60 a 80 años (45.4 %). La letalidad calculada fue de 20.5 por 100 egresos hospitalarios, mientras que la calculada tomando en cuenta los pacientes positivos (ambulatorios y hospitalizados) fue de 6.5.  Conclusiones: El comportamiento epidemiológico de COVID-19 fue similar al descrito en otros estudios; sin embargo, la letalidad y la mortalidad están por encima de la media nacional. Está pendiente el análisis de estas y de los factores que las favorecieron en nuestra población.]]></p></abstract>

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.]]></p></abstract>
