A great friend of mine from college died last week from Covid. She had diabetes. She was 50 yr old, married had 3 boys, brought 12 foster children through their home.
She was a saint of the highest degree.
Waiting to hear more details. Possible transmission Church setting.

We need much more genome tracing!!!

The first 3 are NDIR, the 4th is eCO2. I’ll post a bit later today comparison of ARANET4 with Sensirion SCD30 (not shown) but, both comparable to each other showing much higher CO2 ppm than the other 3 cheaper sensors.

I just started teaching again for the first time since the pandemic started. I had a boat load of anxiety that my room/lab would be off the charts with CO₂. 20 students yesterday in our lab, door closed, CO₂ did not get above 600 ppm for the most part.
But this poor student👇
Testing a new mini keychain NDIR carbon dioxide sensor. $60 & change on Amazon.
Major drawback, auto calibration without option for manual.
It wouldn’t be half bad if it could read lower than 400 ppm, you could easily take the delta between outside vs inside. Not possible 🤬
I just called, it took about 3 min, they attempt to get you go a live agent, but after a couple of minutes of waiting it goes to voice mail.
I left a message expressing how important it is to approve Novavax as soon as possible. There is no logical excuse for this delay.
Another week has passed with no Novavax approval (or any vaccine for that matter).
Please call (again) and keep demanding urgent approval. Novavax and Moderna are ready to go. There is no reason to delay vaccine rollout and yet here we are.
