Rapid screening for variants of concern in routine SARS-CoV-2 PCR diagnostics

Abstract

The emerging spread of variants of concern (VOC) of SARS-CoV-2 has been noted in several countries worldwide during last months. VOCs associated with increased transmissibility and morality. Sequencing is the gold standard for investigation of variants, however it is expensive and time-consuming. S-dropout routine monitoring in combination with VOC screening by RT-PCR is a useful tool for VOC surveillance.
