Abstract
At the global level, a constant change is observed in the proportion of predominant clades since the start of the pandemic to date. As of 5 July 2020, 49% of the samples available through GISAID were associated with the GR clade and by 22 August 2020 it had increased to 53%, whereas by 7 November 2020 the proportion had decreased to 37% and by 22 March 2021 it decreased further to 18% of the proportion of samples. In contrast, there has been a relatively stable trend in proportion of the GH clade, contributing 35% to the total of samples available in GISAID sequenced as of 6 December 2020 and 30% as of 22 March 2021. Regarding the GRY clade, there has been an increase in proportion from 5% as of 6 December 2020 to 39% as of 22 March 2021. A nivel global, se observa un cambio constante en la proporción de clados predominantes desde el inicio de la pandemia a la fecha. Es así como al 5 de julio de 2020, 49% de las muestras disponibles en GISAID se asociaban al clado GR; el 22 de agosto de 2020, la proporción había aumentado a 53%, disminuyendo a 37% al 7 de noviembre de 2020 y a 18% al 22 de marzo de 2021. Por otro lado, se observa que el clado GH ha mantenido una tendencia relativamente estable, aportando 35% al total de muestras secuenciadas al 6 de diciembre de 2020 y 30% al 22 de marzo de 2021. Sin embargo, el clado GRY ha ido en aumento, variando de 5% al 6 de diciembre de 2020 a 39% al 22 de marzo 2021.
