In December 2020, the B.1.1.7 genetic variant of SARS-CoV-2, the virus that causes COVID-19, was first reported after emergence and rapid circulation in the United Kingdom (1). Evidence suggests that the B.1.1.7 variant is more efficiently transmitted than are other SARS-CoV-2 variants, and widespread circulation could thereby increase SARS-CoV-2 infection and hospitalization rates (1,2). The first reported SARS-CoV-2 B.1.1.7 variant case in the United States was confirmed by sequencing in Colorado on December 29, 2020.* This report describes a person who traveled from the United Kingdom to the United States after experiencing COVID-19-compatible symptoms† and was eventually confirmed to be infected with the B.1.1.7 variant.

受感染SARS-CoV-2 B.1.1.7变种的有症状患者从英国到美国的旅行-2021年1月，德克萨斯州。

到2020年12月，SARS-CoV-2的B.1.1.7基因变异（引起COVID-19的病毒）在英国出现并迅速流通后首次被报道（1）。有证据表明，B.1.1.7变种比其他SARS-CoV-2变种更有效地传播，广泛的传播可能因此增加SARS-CoV-2的感染和住院率（1,2）。2020年12月29日在科罗拉多州通过测序确认了美国首例报告的SARS-CoV-2 B.1.1.7变异病例。*该报告描述了一个在经历了COVID之后从英国旅行到美国的人-19兼容的症状†，并最终被确认感染了B.1.1.7变体。
