The phylogenetic analysis shows four independent introductions of N.9 in the state of Rio de Janeiro in October and December 2020, January and March 2021. SARS-CoV-2 N.9 dissemination in the Rio de Janeiro could have been limited by the emergence and dominance of other variants, mainly by the lineage P.2 VOI Zeta that emerged in the same period and co-circulated with N.9, as observed in the neighboring State of São Paulo.
