Update. @my_helix launched a dashboard with our results re virus surveillance
So far, you can check trends in by states for:
- % of SGTF by positives
- Ns & % of B117
Update 🧵 on @my_helix study on the B.1.1.7 variant in the US.
Summary:
- we sequenced 31 samples with S-gene drop out in US
- 4 were B.1.1.7
- 3 from CA, 1 from FL
- Pursuing seq effort with @illumina , & work with @CDCgov
3/
Reminder:
- H69del/V70del variant present in B.1.1.7 likely leads to S gene drop out in RT-PCR assay.
- H69del/V70del is NOT unique to B.1.1.7. Frequent in other clusters (see pic. all of the green is NOT B1.1.7)
Need to sequence to know if S gene drop outs are B.1.1.7.
