de&nbsp;<strong>mascarillas&nbsp;<\/strong>entre la poblaci\u00f3n puede ayudar a frenar la&nbsp;<strong>pandemia&nbsp;<\/strong>y reducir el n\u00famero total de infecciones y muertes por Covid-19, seg\u00fan un estudio que subraya que incluso las de&nbsp;<strong>tela<\/strong>, cuyo efecto protector es limitado, son eficaces si su despliegue es universal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La investigaci\u00f3n, publicada en la revista cient\u00edfica \u201cNature Communications\u201d, ha sido coordinada por Colin Worby, del Instituto Broad del MIT y la Universidad de Harvard (Cambridge, Massachusetts) y por Hsiao-Han Chang, de la Universidad Nacional Tsing Hua de Taiwan (China).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Los cient\u00edficos recurrieron a&nbsp;<strong>modelos matem\u00e1ticos<\/strong>&nbsp;para examinar el impacto del uso de la mascarilla y su distribuci\u00f3n entre la poblaci\u00f3n general durante un brote de&nbsp;<strong>coronavirus<\/strong>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para ello, simularon brotes en los que el suministro y la eficacia de las mascarillas desechables variaban y observaron el n\u00famero de contagios y muertes resultante.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De esta manera comprobaron que el n\u00famero total de muertes e infecciones disminu\u00eda a medida que aumentaban la disponibilidad y la eficacia de las mascarillas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Durante el estudio, los autores plantearon cuatro escenarios de suministro de mascarillas desechables: distribuci\u00f3n aleatoria, distribuci\u00f3n prioritaria a los ancianos, distribuci\u00f3n a ancianos y casos detectados, y distribuci\u00f3n solo a los casos detectados.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En todos sus modelos, se asumi\u00f3 que los trabajadores de la salud y el personal clave tendr\u00edan una protecci\u00f3n adecuada.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Los autores descubrieron que dar prioridad a los ancianos y conservar un suministro de mascarillas quir\u00fargicas para los casos infecciosos identificados era m\u00e1s eficaz y reduc\u00eda los contagios mucho m\u00e1s que con la distribuci\u00f3n aleatoria.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Adem\u00e1s, al evaluar el uso de mascarillas de tela reutilizables, los autores vieron que la reducci\u00f3n de muertes era comparable a la lograda con la distribuci\u00f3n selectiva de mascarillas desechables de calidad m\u00e9dica, incluso cuando los suministros de mascarillas quir\u00fargicas se limitaban al 10% de la poblaci\u00f3n.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tambi\u00e9n descubrieron que cuando todo el mundo las llevaba puestas, las de tela pod\u00edan dar lugar a una reducci\u00f3n del 3 al 5% de las muertes, y que la distribuci\u00f3n selectiva adicional de mascarillas m\u00e9dicas a los ancianos y los sintom\u00e1ticos podr\u00eda duplicar este efecto.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El estudio concluye que el uso de mascarillas faciales es \u201cun componente importante de las medidas de salud p\u00fablica\u201d para limitar la actual propagaci\u00f3n del SARS-CoV-2, si bien, precisa que son necesarias nuevas investigaciones para obtener mejores estimaciones de la eficacia de las mascarillas entre el p\u00fablico durante la pandemia de COVID-19.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>El uso generalizado
