Abstract

The appearance of new variants of SARS-CoV-2 has recently challenged public health authorities with respect to tracking transmission and mitigating the impact in the evolving pandemic across countries. B.1.525 is considered a variant under investigation since it carries specific genetic signatures present in P.1, B.1.1.7, and B.1.351. Here we report genomic evidence of the first likely imported case of the SARS-CoV-2 B.1.525 variant, isolated in a traveler returning from Nigeria.

摘要

最近，SARS-CoV-2 的新变体的出现给各国的公共卫生部门带来了挑战，需要追踪其传播并减轻其在不断演变的大流行中的影响。B.1.525 被认为是一种正在调查的变体，因为它携带 P.1、B.1.1.7 和 B.1.351 中存在的特定遗传特征。在这里，我们报告了首例可能从尼日利亚返回的旅行者中分离出的 SARS-CoV-2 B.1.525 变体的基因组证据。
