With overall number of cases 📉 quickly => important to look at % of positives that are B1.1.7
AND also the evolution of the absolute number of B1.1.7
Can do this based on Helix numbers,
or by multiplying % from Helix by overall number of cases reported by states and CDC
3/ CA: % of positives that are B117 now ~15-17%
Increase in absolute numbers of B117 is slower (compared to FL).
Still N of B117 is not decreasing, unlike the non-SGTF SARS-CoV-2 variants including B.1.429 & B.1.427 who are decreasing fast.
- New dashboard: you can check all lineages now
Random ex: B.1.1.64 in 4 states (note: I don't know anything about this variant). public.tableau.com/profile/helix6…
- SGTF info up to Feb 15
- Seq info up to Jan 30
🧵 with more results
2/
Of the variants of concern, so far we only identified B.1.1.7 (666 times up to Jan 30). No B.1.351 and no P.1
We identified many B.1.429, a variant of interest. It represents about 20% of the sequences we do every day. But sampling is still biased for SGTF

To assess fraction compared to non-SGTF sequenced, you can also get that info from the 2 files on Github with ALL of the data.
