[Clinical and epidemiological characteristics of patients hospitalized for SARS-CoV-2 infection in two hospitals in Córdoba].

Introduction: COVID-19 disease shows a marked heterogeneity in its clinical course, with descriptions of some factors associated with a worse prognosis. Knowledge of the disease behavior in the local scenario is relevant to allow a better approach.

Methods: Retrospective study in two hospitals in the city of Córdoba, Argentina, with patients aged 18 years or more, hospitalized for active SARS-CoV-2 infection, from March to October, 2020.

[Leukoerythroblastic reaction associated with COVID-19 infection. Case report].

Introduction: COVID-19 disease is an acute viral pneumonia with multiple extrapulmonary manifestations, including certain hematological alterations. The leukoerythroblastic reaction or leukoerythroblastosis is defined by the presence in peripheral blood of nucleated erythroid cells and immature myeloids. Among its most frequent causes is medullary invasion by solid tumors and hematological neoplasms, so the recognition and consequent study of this reaction is extremely important.
