A New SARS-CoV-2 Variant Poorly Detected by RT-PCR on Nasopharyngeal Samples, with High Lethality

2021-05-12

Abstract excerpt

Background: In early January 2021, an outbreak of nosocomial cases of COVID-19 emerged in Western France, with RT-PCR tests repeatedly negative on nasopharyngeal samples but positive on lower respiratory tract samples. Whole genome sequencing (WGS) revealed a new variant, currently defining a novel SARS-CoV-2 lineage: B.1.616. In March, WHO classified this variant as ‘under investigation’ (VUI). We analyzed the c...
