What went wrong in SoCal? "Part of the reason for the new surge appears to be the Thanksgiving effect. Many Californians, particularly those in & near LA, held small gatherings for Thanksgiving with family & friends, despite warnings from officials." 1/ nytimes.com/2021/01/09/us/…
"...the state’s early success in the pandemic may have given Californians a false sense of security...The very successes that we had built in a potential complacency from the part of people thinking it’s maybe not that severe.” 2/
"Young people who had isolated themselves gathered in large groups & stretched the limits of what constituted outdoor dining to include rooms with large windows. The taboos of the first months of the pandemic, like meeting friends inside their homes, fell away." 3/
"Another reason...has been...dense housing...Many poor & middle-class families...pack into homes & apts, w/ generations of...family or members of different families living under the same roof...often low-wage essential workers who do not have the luxury of working from home." End

In 2010, I noted lessons from the 2009 H1N1 influenza pandemic, incl. epi/surveillance, healthcare system response, communication, mitigation strategies, & the vaccination program. Regrettably, most are just as relevant today, many opportunities missed. 1/ nap.edu/read/12799/cha…
In 2010, I described racial & ethnic disparities, inadequate public health resources/funding; value of enhanced surveillance methods; hospital overload & PPE shortages; drug distribution problems & perhaps most noteworthy at the moment, challenges w/ the vaccination program. 2/
A few key points on vaccination follow. "The need to rapidly plan and implement a large-scale vaccine distribution & administration system severely taxed local public health capacity..." 3/

Straight Talk About the New Variant COVID-19 Strain. As much as I regret saying it just when so many need & deserve a break, the new variant COVID-19 strain is a serious problem. It’s likely a matter of time before it arrives here & we need to beware & prepare. Here’s why. 1/
All viruses mutate resulting in new strains that vary from their ancestors. These are called variant strains. Most coronavirus mutations don’t fundamentally change how the virus behaves or affects us. 2/
However, at least one newly recognized strain, often called B.1.1.7., “SARS-CoV-2 VOC 202012/01” or an "N501Y" strain, has been shown to have multiple mutations that are changing the way the virus behaves in important ways. 3/
From a celestial perspective, the darkest days of the year are behind us & we can look forward to more sunlight each day. Let's do everything we can to put the darkest days of COVID-19 behind us as well. 1/n
What we do for the last few days of 2020 (good riddance!) will determine what 2021 holds in store. It’s especially important to double-down on CoV-19 prevention now, when the virus has the advantage as we spend more time indoors & environmental conditions favor transmission. 2/n
Our hospitals are strained. New variants of the virus have been identified in other countries that seem to spread more easily and may appear here as well. But the basic COVID-19 prevention steps are just effective against all COVID-19 viruses. 3/n
FDA will review data for authorizing the 1st vaccine to prevent COVID-19 tomorrow. The vaccine is made with an exciting new technology, mRNA. I'm sharing some information from @CDCgov about mRNA vaccines & how we got here so quickly without compromising effectiveness & safety. 1/
What is mRNA? It's a "molecular blueprint" for a cell to make proteins. In this case, mRNA instructs our own cells where the vaccine is injected to make a protein found on the surface of the SARS-CoV-2 virus. Our immune system then develops a protective response against it. 2/
In contrast, most vaccines use weakened or inactivated versions or components of a virus or bacteria to stimulate the body’s immune response. Weakened live virus vaccines like MMR & varicella work by replicating in our cells using the vaccine virus' mRNA. 3/
Significant update from CDC states mask use protects not only others but the wearer: "Masks also help reduce inhalation of these droplets by the wearer (“filtration for personal protection”)." 1/n
"The community benefit of masking for SARS-CoV-2 control is due to the combination of these effects; individual prevention benefit increases with increasing numbers of people using masks consistently and correctly." 2/2
Masks should be well made & fit well (snug w/out gaps) "Multiple layers of cloth with higher thread counts have demonstrated superior performance compared to single layers of cloth with lower thread counts, in some cases filtering nearly 50% of fine particles less than 1 micron."
