Abstract: We studied SARS-CoV-2 genomes from travelers arriving in Hong Kong from November-2021 to February-2022. Apart from detecting Omicron (BA.1, BA1.1. and BA.2) and Delta variants, we detected a BA.1/BA.2 recombinant in two epidemiologically linked cases. This recombinant has a breakpoint near the 5’ end of Spike gene (nucleotide position 20055-21618).
