Figure 1.

Global distribution of SARS-CoV-2 VOCs as reported in GISAID. (A) Number of Omicron and (B) all VOC genome sequences reported in GISAID. (C) Number of four VOCs and Omicron genome sequences (continent-wise) are presented. (D) Density plot shows the probability density distribution of five VOC genomic sequences based on age of COVID-19 cases. Only 38% (4.55 million) of the VOC sequences described the patient’s age (0–100 years) were considered. (E) Density plot displays the distribution of the consolidated number of all five VOC genomic sequences based on gender. (F) Phylogenetic tree based on a subset of globally circulating VOCs sequences created by Nextstrain (accessed on 22 October 2022).
