Although zero-low domestic transmission of SARS-CoV-2 has been prolonged, imported cases with different viral variants have yet occurred in Vietnam This article is protected by copyright. All rights reserved.

Vietnam for 14 days as required by the current quarantine protocols for all incoming international arrivals to Vietnam. After 2 days, she was tested positive for SARS-CoV-2 using real-time reverse-transcription polymerase chain reaction (a cycle threshold of 24). She reported that she wore a personal protection equipment (PPE) kit, including a facemask, gloves, goggles, shoe covers, and disposable coveralls bodysuit during her return to Vietnam. She additionally reported that she had not been exposed to any known COVID-19 cases in the United Kingdom before departure. F I G U R E 1 Phylogenetic tree of the complete genomes of SARS-CoV-2 isolated from two patients returning to Vietnam from the United Kingdom in December 2020. Dots indicate the SARS-CoV-2 strains isolated in this study (EPI_ISL_760247 and EPI_ISL_812922). Complete genome sequences were aligned with other related coronavirus sequences archived from GenBank/GISAID using Mafft software and constructed a phylogenetic tree using the maximum likelihood method with 1000 bootstrap replicates in MEGA-X using the general timereversible model. The bootstrap values were indicated on branches
