Abstract
SARS-CoV-2 variants raise concern regarding the mortality caused by COVID-19 epidemics. We analyse 88,375 cycle amplification (Ct) values from variant-specific RT-PCR tests performed between January 26 and March 13, 2021. We estimate that on March 12, nearly 85% of the infections were caused by the Alpha variant and that its transmission advantage over wild type strains was between 38 and 44%. We also find that tests positive for Alpha and Beta/Gamma variants exhibit significantly lower cycle threshold (Ct) values.

SARS-CoV-2 변종은 COVID-19 전염병으로 인한 사망률에 대한 우려를 불러일으키고 있습니다. 우리는 2021년 1월 26일과 3월 13일 사이에 수행된 변이형 특이적 RT-PCR 검사에서 88,375개의 주기 증폭(Ct) 값을 분석합니다. 야생형 균주에 비해 이점은 38%에서 44% 사이였습니다. 우리는 또한 알파 및 베타/감마 변이체에 대해 양성인 테스트가 상당히 더 낮은 사이클 임계값(Ct) 값을 나타낸다는 것을 발견했습니다.
