Dec. 14th, 2020, UK reported a new variant strain of SARS-CoV-2 (known as 20B/501Y.V1, VOC 202012/01, or B.1.1.7 lineage) to WHO which emerged with an unusually large number of mutations. This variant has since been detected in numerous countries around the world, including the United States (US) and Canada. According to the new research from the Department of Health of UK, based on the data of whole genome sequencing, epidemiology and modeling, the infectiousness of variant strain of SARS-CoV-2 is almost 40-70% higher than other discoverable modification scientist recognized.
This variant of B.1.1.7 has been detected in China after UK reported, so rapid response and detection is one of the vital prevention and control measure. Till this report, there are 14 Chinese IVD enterprise successfully developed the B.1.1.7 testing kits as follows:
