2. That's 20-40% of people who get infected and never show symptoms. More likely in young. Who don't understand they are propagating the pandemic
"Usually a virus that is good enough to kill you would make almost everybody at least a little bit sick."
3. The chronic "long covid" post-viral symptoms of #COVID19 are common, understudied to date.
"And it's extraordinary how many people have a postviral syndrome that's very strikingly similar to myalgic encephalomyelitis/chronic fatigue syndrome."
4. We don't have a #COVID19 czar with decision-making authority, like @RonaldKlain for Ebola (who Fauci loves) but @VP has taken on a lead role, is receptive, and "deeply involved." Fauci is very respectful to the Administration despite all the efforts of @POTUS to undermine him
5. What about the @HHSgov hijacking the @CDCgov covid data?
Fauci only learned about it by watching television
6. What about the hyperimmune response to #COVID19 and that being implicated as the basis for most fatalities?
7. It took 5 days from the sequence of #SARSCoV2 to Fauci's team to get the start on a vaccine, 62 days to get Phase 1 clinical trial started (That is simply incredible)
8. What about short-lived antibodies to the virus and the role of T cells? #SARSCoV2 is like SARS with a significant and enduring T cell response. We shouldn't be worried about the IgG antibody waning report that got a lot of buzz this week.
9. What about reinfection, does it occur?
There are anecdotes, but no proof of replication competent virus. So if it really exists it's rare (considering millions of infections). Hard to prove since you need a BSL-3 lab to correlate PCR results of RNA nucleotides w/ live virus
10. On the mask pushback, Fauci attributes this to the "disturbing anti-science trend" My worry is that will extend to implementing the vaccine, but we didn't get to that issue
11. Monoclonal (neutralizing) antibodies were developed for Ebola and highly successful They are now in clinical trials for SARSCoV2, very potent, and will likely be used in early and late stages of treatment. Mabs don't get the attention of vaccines but very important & imminent
12. Rapid diagnostic kits for home or point of care are in the works, NIH has invested $500 million, results in < 30 mins. These will be transformative when they are available this fall
13. Favorite part: his comments to the frontline heroes and how science will prevail.

We've learned a lot more about the principal drivers of age-related diseases in the past few weeks. And that leads to a unified model to pull it all together. (open-access)
I review 4 new reports, summarized here: 1. The proteins from senescent cells predict age-related clinical outcomes 2. A new epigenetic age clock connects the dots between aging, the immune system, inflammation and lifestyle factors 3. People with a fast pace of aging had an increased risk of cognitive impairment, age-related diseases, disability, and mortality 4. The Importance of “Immune Resilience” for Healthspan
And present a unified I/I model for what we now know
Most people haven’t heard of this test, which is available in the US. It accurately predicts Alzheimer’s (not just if there’s a risk, but when). It is favorably affected by exercise and likely many other lifestyle factors.
Here’s (almost) everything we know about it. In Ground Truths (link in my profile d/t X-suppression)
A major @Nature paper this week found a significant decline in dementia after an outdated Shingles vaccine.
I've reviewed the study and many other relevant ones in a new Ground Truths (link in profile)
A Table from the post
The effect in the 2 natural experiments differed substantially by sex with the benefit predominant in women
The vaccine against Shingles helps protect against dementia, results of a natural experiment, adding to prior evidence
"implications are profound"
New @Nature nature.com/articles/s4158… nature.com/articles/d4158…
Of >105,000 participants with 30-year follow-up, only 9.3% achieved healthy aging (age 70, w/o any chronic diseases). Their diet was significantly associated with this outcome🧵 @NatureMedicine
These are the specific foods that were linked with healthy aging and other outcomes. Green-favorable; Red-unfavorable
Adherence to these diets (most to least in quintiles) linked to healthy aging
A paper on microplastics accumulating in the brain was just published @NatureMedicine, open-access
I review the background and major implications in a new Ground Truths edition (link in my profile)nature.com/articles/s4159…
The human brain:
—had 7-30 times more accumulation of microparticles (MPs) than the liver or kidney (organs with previously documented high propensity)
—from people with dementia had 5X accumulation of MPs compared with non-dementia
—there was a marked increase of accumulation over recent years
