We updated @my_helix viral surveillance dashboards.

- SGTF dashboard still here => important to see in real time if a variant is outcompeting B.1.1.7 in some states

- Selected variants dashboard. You can see P.1, B.1.617.2 & others. public.tableau.com/profile/helix6…

Using the SGTF dashboard:
public.tableau.com/profile/helix6…

In some states like FL, SGTF 5-day avg is 📉 66% on May 9 compared to 71% 10 days before. & SGTF likely still >95% B.1.1.7

So what is the 34% and maybe growing?

You can look at the variants dashboard. It shows sequencing results.
public.tableau.com/profile/helix6…
See overall trend. And counts by state (click on specific variant).

Here, we observed 237 counts of P.1. in FL.

4/
Trend in Florida for all vars. And we know B.1.1.7 decreasing ~5% as of May 9. Likely P.1. will be growing to 10-15%, but maybe it is B.1.617.2 appearing or other?

5/
Forgot to mention, that you can see actual counts per day if you scroll over the bar.

ex in screenshot below. P1 represents 10.42% of 144 sequences in FL from samples collected on April 19.

Thanks @simonjwhite71 for the magic behind

6/ Also be careful when looking at the most recent day. Data is usually incomplete for the most recent day reported.

7/
Some interesting points.
In PA, B.1.526 is holding pretty well compared to B.1.1.7.

8/
In Michigan, B.1.526.1 seems to be the variant that is the last to keep up with B.1.1.7.

9/
For B.1.617.2, we observed 30 (see distribution 👇). Not enough to make any hypothesis.

Some great threads today by @theosanderson & @TWenseleers on this variant.
