Abstract
We have detected novel SARS-CoV-2 variants at the airport quarantine facility in Japan. This study revealed novel Omicron recombinant in a traveller visiting from Nepal, suggesting a possibility of its further dissemination in surrounding countries with limited sequencing capacity. Quarantine monitoring could aid timely response to avoid global dissemination.
摘要
我们在日本机场检疫设施中检测到了新型的 SARS-CoV-2 变种。本研究在一名来自尼泊尔的旅行者中发现了新型奥密克戎重组株，提示其在测序能力有限的周边国家进一步传播的可能性。检疫监测有助于及时响应，避免全球传播。
