Overview
Durante el último mes, las cepas del SARS-CoV-2 Omicron han dominado los noticiarios del mundo. Esta variante de rápida transmisión ha llevado a limitar viajes, a cancelar planes de vacaciones, al agotamiento de los kits de pruebas, a la vuelta de los confinamientos, y además a un asombroso número de nuevos casos de COVID-19. Los científicos rápidamente se han puesto a estudiar Omicron, intentando entender qué tan rápido se transmite, qué tanto nos enferma, y si es resistente a los tratamientos, a las vacunas, y a los anticuerpos de infecciones de COVID previas. Necesitamos revisar todas estas cuestiones porque Omicron es muy diferente de otras cepas de coronavirus. Omicron ha acumulado más de 50 nuevas mutaciones en comparación con la cepa que empezó la pandemia. Además Omicron no es un descendiente de la cepa Delta, responsable de la anterior ola de infecciones. De hecho, Omicron es tan diferente de otras variantes que parece que ha estado evolucionando por su cuenta durante muchos meses. Y esto nos conduce a otro misterio que los científicos están tratando de resolver: ¿dónde estaba Omicron escondido mientras toda esta evolución tenía lugar?
