Abstract excerpt

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.33-derived lineage named N.9 was described recently in Brazil and it's considered a potential variant of interest (VOI) due to the presence of E484K substitution at the receptor-binding domain (RBD) of the Spike (S) protein. OBJECTIVE: To describe the first detection of variant N.9 in Rio de Janeiro State. METHODS: SARS-CoV-2 N.9...
