In December 2019, a new virus appeared in Wuhan (China), SARS-CoV-2, the origin of the disease called COVID-19 that has currently caused a pandemic that devastates the planet. Globally, the scientific community is dedicating all its efforts to understand the virus, the disease and to find solutions that will lead the world out of this nightmare. This article reviews the data on the evolution of the disease, describes the biological processes that cause the major part of the deaths, and discusses the treatments used to mitigate the disease. In addition, and taking into account that it is a viral disease, the status of the only possible solutions are described; which are the discovery of a potential drug, the development of a vaccine, and the achievement herd immunity. Likewise, we present a simple mathematical model of the growth and decay of the number of cases. This document is written ...

La tesis tuvo como objetivo general proponer un modelo de gestión administrativa para mejorar la calidad de servicio en la Municipalidad distrital de la Victoria, Lima 2019. La tesis fue de tipo propositiva porque se basa en una solución que existe dentro de una institución, en este caso dentro de la Municipalidad; asimismo se tomó una información detallada para ver los problemas existentes por la cual se elaboró estrategias de gestión administrativas para mejorar la calidad de servicio de la MDLV. Se aplicaron cuestionarios validados a 355 usuarios dentro de la Municipalidad. La tesis concluye que la situación actual de la gestión administrativa en la municipalidad distrital de La Victoria se obtuvo que el 91% de los encuestados opinaron que se encuentra en un nivel medio, por lo tanto, gestión administrativa aún se haya en proceso para lograr el nivel alto que sería una ges...
