Results: Data on COVID-19 diagnosed cases and mortality, from January 1st, 2020, onwards is collected automatically from the European Centre for Disease Prevention and Control (ECDC). We have developed a Shiny application for data visualization and analysis of several indicators to follow the SARS-CoV-2 epidemic using ECDC data. A country-specific tool for basic epidemiological surveillance, in an interactive and user-friendly manner. The available analyses cover time trends and projections, attack rate, population fatality rate, case fatality rate, and basic reproduction number. Conclusions: The COVID19-World online web application systematically produces daily updated country-specific data visualization and analysis of the SARS-CoV-2 epidemic worldwide. The application may help for a better understanding of the SARS-CoV-2 epidemic worldwide.7 p.application/pdfengcc by (c) Tebé et al., 2020http://creativecommons.org/licenses/by/3.0/es/COVID-19Infeccions per coronavirusMortalitatSARS-CoV-2COVID-19Coronavirus infectionsMortalitySARS-CoV-2info:eu-repo/semantics/article2021-01-25info:eu-repo/semantics/openAccess32958001
