Las tecnolog\u00edas de rastreo de contactos dise\u00f1adas para tel\u00e9fonos inteligentes han funcionado como una \u00fatil herramienta en la lucha contra la propagaci\u00f3n de COVID-19 en el mundo. Ya que son una forma segura de aislar a las personas que han tenido contacto con un caso confirmado de la enfermedad. Por otra parte, a trav\u00e9s de los tel\u00e9fonos m\u00f3viles tambi\u00e9n es posible medir los datos de movilidad de la poblaci\u00f3n y a trav\u00e9s de su an\u00e1lisis tomar mejores decisiones sobre las restricciones de movilidad. En el art\u00edculo: &#8220;Simular epidemias de SARS-CoV-2 por variables espec\u00edficas de la regi\u00f3n y modelar la contenci\u00f3n de la aplicaci\u00f3n de rastreo de contactos&#8221;, publicado en npj Digital Medicine de la revista Nature, los autores plantean la aplicaci\u00f3n de un modelo SIR \u2014modelo que se basa en el an\u00e1lisis de la transici\u00f3n de los individuos susceptibles a la infecci\u00f3n (S) al estado de individuos infectados que infectan (I) y, finalmente, al de recuperados (curados o fallecidos) (R)\u2014 enfocado en COVID-19. El objetivo del estudio y espec\u00edficamente de la construcci\u00f3n del modelo SIR, fue reproducir fielmente la din\u00e1mica de las epidemias de SARS-CoV-2, incluidas las funciones respectivas de la infecci\u00f3n asintom\u00e1tica y la densidad de poblaci\u00f3n y probar los efectos de distintas intervenciones, y espec\u00edficamente el uso de aplicaciones telef\u00f3nicas para rastrear contactos, seg\u00fan explican los autores en el apartado de Resultados. Para dicha investigaci\u00f3n fueron utilizados datos demogr\u00e1ficos de Espa\u00f1a e Italia, tomando en cuenta la densidad poblacional espec\u00edfica de cada regi\u00f3n, adem\u00e1s tambi\u00e9n probaron el impacto de la aplicaci\u00f3n de rastro de contactos en una serie de escenarios planteados. \u201cNuestros resultados muestran que, en apoyo del aislamiento eficiente de casos sintom\u00e1ticos, el rastreo de contactos mediado por aplicaciones puede mitigar con \u00e9xito la epidemia incluso con una fracci\u00f3n relativamente peque\u00f1a de usuarios, e incluso suprimir por completo con una fracci\u00f3n mayor de usuarios\u201d, explicaron los autores. No obstante, reconocen que la densidad de poblaci\u00f3n es un aspecto cr\u00edtico que puede determinar la dificultad de contener o no los contagios. \u201cNuestro objetivo fue modelar el efecto del rastreo de contactos mediado por aplicaciones teniendo en cuenta la densidad de poblaci\u00f3n y el transporte, al mismo tiempo que permitimos monitorear el n\u00famero de pacientes que est\u00e1n en cuarentena y su estado con respecto a la infecci\u00f3n\u201d, explican sobre el uso del rastreo de contactos como una herramienta para controlar los contagios de COVID-19 al levantar las restricciones en la movilidad. En sus resultados generales, explican que la cuarentena voluntaria, registrada gracias a las apps de rastreo de contactos, as\u00ed como el aislamiento de casos confirmados, contribuyen al control de la epidemia, sin embargo, se deben tomar en cuenta factores como la densidad de poblaci\u00f3n y la movilidad en transporte p\u00fablico, por ejemplo.
