Figure 1.

Cross reference of variants of concern (VOC) and (VOI) variants of interests (Y-axis) and the occurrence and frequency of point mutations (X axis). Mutations and frequency were measured with >90% prevalence of that specific mutation in at least one lineage. Text in red represent variants/mutations of concern. Yellow: variants/mutations of interest. White text: variants/mutations under surveillance or observation. Graphic modified from outbreak.info website [46] and customized to show only the VOC and VOI currently spreading in South America. By the time of manuscript writing, a few cases of Omicron were present in South America but reached over 10% in South Africa and over 3% in the fourth wave of infections in Europe in the last month.
