• Omicron genetic and epidemiological characteristics in Southern, Brazil. • Completely Omicron mutational data. • Gamma variant was completely displaced by Omicron in a short period of time. • First time identification of a new Omicron variant of concern: Omicron-L452R. Recently, SARS-CoV-2 Omicron variant (B.1.1.529) was first identified in Botswana in November 2021. In a short period of time, this highly mutated variant replaced the previous dominant Delta variant, causing an exponential increase in the number of COVID-19 cases, resulting in a new wave of pandemic. This current research article aims to analyze and summarize information about the genetic characteristics, amino acid mutations and epidemiological data providing scientific findings to enrich the SARS-CoV-2 knowledge. More importantly, we describe here, for the first time, the identification of a new Omicron variant of concern: Omicron-L452R in Brazil. [ABSTRACT FROM AUTHOR]
