Since March 2020, 11 lineages of severe acute respiratory syndrome coronavirus 2 have been identified in Sergipe state, Northeast Brazil. During the first 6 months of coronavirus disease 2019 (COVID-19) outbreak, there was a higher frequency of B.1 (58.5%) and B.1.1.33 (17.1%) lineages. During the second wave of COVID-19, there was an increased frequency of P.1 (55.6%), the new Brazilian variant of concern.

On January 29, 2021, we identified a new circulating lineage of SARS-CoV-2 in Brazil, located in Sergipe state, Northeast region. The B.1.1.251 lineage was identified in a 32-old-man with headache, sore throat, and coryza. Further studies are needed to evaluate the transmissibility and virulence of this emergent coronavirus lineage in Brazil.
