pueden tener un mayor riesgo de reinfecci\u00f3n con la variante Omicron que con versiones anteriores del virus, seg\u00fan los hallazgos preliminares publicados en <a href=\"https:\/\/www.medrxiv.org\/content\/10.1101\/2021.11.11.21266068v2\">medRxiv.<\/a><\/p>\n<p>En Sud\u00e1frica, donde se report\u00f3 por primera vez sobre la variante Omicron, los investigadores revisaron datos sobre casi 2,8 millones de infecciones y vieron que, si bien el riesgo de una primera infecci\u00f3n aumentaba cuando las variantes Beta y Delta anteriores se extendieron durante la segunda y tercera oleadas de la pandemia, el riesgo de reinfecci\u00f3n no cambi\u00f3.<\/p>\n<p>Pero el mes pasado, a medida que se propagaba Omicron, el n\u00famero diario de reinfecciones se dispar\u00f3, informaron los investigadores del Instituto Nacional de Enfermedades Transmisibles de Sud\u00e1frica.<\/p>\n<p>De acuerdo con estos primeros datos, el riesgo de reinfecci\u00f3n de los supervivientes puede estar aumentando m\u00e1s r\u00e1pidamente que el riesgo de una primera infecci\u00f3n de una persona promedio.<\/p>\n<p>Los autores concluyen que las evidencia a nivel de poblaci\u00f3n sugieren que la variante Omicron est\u00e1 asociada con una capacidad sustancial para evadir la inmunidad de una infecci\u00f3n previa.<\/p>\n<p>La buena noticia es que, de momento, no hay evidencia epidemiol\u00f3gica en toda la poblaci\u00f3n de escape inmunol\u00f3gico asociado con las variantes Beta o Delta.<\/p>\n<p>Este hallazgo tiene importantes implicaciones para la planificaci\u00f3n de la salud p\u00fablica, particularmente en pa\u00edses como Sud\u00e1frica con altas tasas de inmunidad debido a infecciones previas.<\/p>\n<p>Sin embargo, sigue habiendo preguntas urgentes sobre si Omicron tambi\u00e9n es capaz de evadir la inmunidad inducida por la vacuna y las posibles implicaciones de la una inmunidad reducida a la infecci\u00f3n en la protecci\u00f3n contra enfermedades graves y la muerte.<\/p>\n<p><em>Foto: Shutterstock.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>El riesgo de reinfecci\u00f3n de los
