Tracking SARS-CoV-2 VOC 202012/01 (lineage B.1.1.7) dissemination in Portugal: insights from nationwide RT-PCR Spike gene drop out data

Thank you. It is important to know that you see the same effect. In our data, the difference in Ct’s seems highly consistent around 6-7. We have just sequenced more “late amplification” cases, again confirming B.1.1.7. Other assays are under way. We tentatively designated “late amplification” (to denote the delay) but it may worth thinking in another designation better reflecting the technical reason. Thanks.
