This article presents the complete coding sequences of two severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2) strains that were recovered from a naso-pharyngeal swab from a female patient and the second viral passage in cell culture. After
testing, both strains were identified as BA.5.2.20, a subvariant of Omicron.
