SARS-CoV-2 R.1 lineage variants prevailed in Tokyo in March 2021

2021-05-17

Abstract excerpt

<h4>Background</h4> The spread of SARS-CoV-2 variants, such as B.1.1.7 and B.1.351, has become a crucial issue worldwide. Therefore, we began testing all patients with COVID-19 for the N501Y and E484K mutations by using polymerase chain reaction (PCR)-based methods. <h4>Methods</h4> Nasopharyngeal swab samples from 108 patients who visited our hospital between February and April 2021 were analyzed. The samples wer...
