Officials say that there are now five confirmed cases of the B117 coronavirus variant -- often called the UK strain -- in LA County.
LA County public health director Barbar Ferrer: "I would just note: there's no way that we don't have a fair amount of variant circulating, a fair amount of mutated virus circulating. It's just a question of how much and does it become dominant."
Barbara, not Barbar 🤦‍♀️
LA County public health director Barbara Ferrer: "We haven't yet seen the South Africa variant in any of the sequencing we've done, but that doesn't mean it's not here. Which is why we're just saying to everyone, 'Assume it's here.'"
Ferrer says it's unlikely that LA County's surge that began in November was caused by the UK variant. "What is possible is that there were mutations that were circulating that could in fact have been slightly more infectious," she says, mentioning the so-called California variant
A thing I've noticed: LA Mayor Eric Garcetti often blames the big fall surge here on more infectious coronavirus variants, while our health officials do not. This is what LA County public health director Barbara Ferrer said today:
Ferrer: "I don't want to sort of just go ahead and imply in any way that there was a more infectious variant and that was really the main driver. We could end up finding out that that contributed ..."
Ferrer: "...but the main drivers to our increases were in fact people were just not playing by the rules at the time. A lot of gatherings where people were not safe, they did not wear their face coverings and it's a virus that's easily transmitted, variant or not variant."

How many people are wearing cloth masks on top of KN95s?

The CDC's new masking guidance recommends wearing a cloth mask over a disposable mask, but it asks that people NOT layer KN95s. KN95s are meant to be worn on their own, it says.
I'm trying to find out more soon on why they're recommending this, but I'm wondering if it's because KN95s have a structure to them and if you put something on top it might flatten the mask, and reduce the tightness of the seal? Hopefully will know more soon.
This is from the CDC's new masking guidance: cdc.gov/coronavirus/20… Image

The CDC is updating its mask guidance today to recommend new ways to make masks fit more tightly, including double-masking, knotting the ear loops or using a moldable nose wire. This is based on new science released today.
CDC researchers conducted an experiment in which they simulated aerosolized COVID-19 transmission between two people, and found that exposure was reduced by more than 95% when both people were wearing a cloth mask over a medical procedure mask.
"Masks work, and work best when they have a good fit and are worn correctly," says CDC director Dr. Rochelle Walensky.

I just heard someone say that North Dakota and Arizona have way lower death rates from COVID than California, and that they've managed it without all our rules.

That's just not true! Everyone loves to bash California, but our death rate from COVID ranks 33 out of 50 states 🙃
Nearly 41,000 Californians have died from COVID -- about 1 of every 1,000 residents

If we had the same death rate as Arizona or North Dakota, we'd have around 75,000 dead. Even the rate of Florida, which everyone love to compare us to, would bring our toll to 50,000
Idk why people think California is doing so much worse than it is. It might be news coverage highlighting how big our surge has been -- it was undoubtedly huge, I don't dispute that -- or just that people like to make fun of California
