Really just so proud of all the people at @ucdavis and at @HealthyDavis and #DavisCA involved in this. And happy to play a supporting role.
A California College Tries to Shield an Entire City From Coronavirus
1. Helping w/ environmental testing for #SarsCoV2 (projects being led by others such as @davidacoil @colorsofwater)
2. Running a @ucdavis course where students work at testing kiosks
#HealthyDavis
For more on course see https://t.co/RUevWn6F4B and https://t.co/tzeude6k08 #HealthyDavis
One shout out I want to make now is to @UCDavisSHCS and their director Dr. Cindy Schorzman. They have been the group coordinating all the testing on campus and been remarkable.
More soon.

I've seen many news articles cite that "the UK variant could be the dominant strain by March". This is emphasized by @CDCDirector.
While this will likely to be the case, this should not be an automatic cause for concern. Cases could still remain contained.
Here's how: 🧵
One of @CDCgov's own models has tracked the true decline in cases quite accurately thus far.
Their projection shows that the B.1.1.7 variant will become the dominant variant in March. But interestingly... there's no fourth wave. Cases simply level out:

Just because a variant becomes the dominant strain does not automatically mean we will see a repeat of Fall 2020.
Let's look at UK and South Africa, where cases have been falling for the past month, in unison with the US (albeit with tougher restrictions):
Furthermore, the claim that the "variant is doubling every 10 days" is false. It's the *proportion of the variant* that is doubling every 10 days.
If overall prevalence drops during the studied time period, the true doubling time of the variant is actually much longer 10 days.
Simple example:
Day 0: 10 variant / 100 cases -> 10% variant
Day 10: 15 variant / 75 cases -> 20% variant
Day 20: 20 variant / 50 cases -> 40% variant
1) Proportion of variant doubles every 10 days
2) Doubling time of variant is actually 20 days
3) Total cases still drop by 50%
