Nociones de epidemiología en tiempos de COVID-19

Abstract

Basic notions of epidemiology are necessary to ana- lyze and define adequate prevention and containment

measures at individual, regional and global levels during the COVID-19 pandemic. This article reviews

the steps for a systematic approach to epidemic situa- tions with detail of the minimum epidemiological pa- rameters for this. It also offers an overview of the mul- tiple edges presented by a health crisis situation, the

tools available and the questions that remain open.
