After more than a year of the pandemic situation of COVID-19, the United Kingdom (UK), South Africa, and Brazil became the epicenter of new lineages of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Variants of Concern (VOCs) were identified through a continuous genomic surveillance global effort, the B.1.1.7 (Alpha), B.1.351 (Beta), B.1.617.2 (Delta), and P.1 (Gamma) harboring a constellation set of mutations. This research aims to: (i) report the predominance of the Gamma (P.1) lineage presenting the epidemiological situation of the SARS-CoV-2 genomic surveillance at the state of Tocantins, and (ii) describe the emergence of possible new mutations and viral variants with the potential new lineage (P1-related) represented by 8 genomes from the Tocantins harboring the mutation L106F in ORF3a. At the moment, 6,687 SARS-CoV-2 genomes from GISAID carry this mutation. The whole-genome sequencing has an important role in understanding the evolution and genomic diversity of SARS-CoV-2, thus, the continuous monitoring will help in the control measures and restrictions imposed by the secretary of health of the state to prevent the spread of variants.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
