🧵 1/ This morning in my Lyft to the hospital, my driver asked me about the #covid19 vaccines.

He said he was skeptical, both of the pharmaceutical industry, and even more so of politicians.

I often wonder how many conversations like this happen informally every day.
2/ He then asked me about hydroxychloroquine. He referenced the previous administration’s pushes for this. He asked if it worked and actually said he heard about a doctor in Texas that was “curing” patients with it.
3/ I encouraged him that the vaccines were in fact safe- I reassured that I had taken it over a month ago now & I was fine, as were all of my colleagues who have been vaccinated at work thus far. I tried to explain why hydroxychloroquine was not in fact a “cure” for #covid19
4/ It was a pleasant conversation. But it was alarming at the same time. Misinformation is circulating alongside the virus- including myths about drugs that we have shown to be ineffective for months on end. It was a reminder that change is a person to person process.
5/ If you’ve been vaccinated, please make sure to connect with a few people in your circles who may be having fears about the safety of the vaccine. Being able to hear from you makes a difference. I really believe that our conversation this morning did as well. #covid19

🧵🧵1/ When people ask which mask is “good enough”, I often try to reframe it as better protection is better protection; everything we are doing is to reduce risk.

Is an N95 better than a cloth mask? Yea, it is

Is a cloth mask better than no mask? Yea, it is

#covid19
2/ If there was a good reason to not wear an N95 or equivalent mask during indoor crowded activities, then we wouldn’t be pushing for it.

But frankly, most of the reasons presented have been weak.
3/ The CDC Director on CNN once said it was bc they are hard to breathe through.

I don’t think so

I have worn them for hours at a time in the hospital

We are calling for people to wear them when in higher risk indoor settings. This likely won’t be for hours most of the time

🧵 1/ Presumed #covid19 reinfection (first cases mild, second cases more severe) in five elderly Kentucky nursing home residents w/ multiple co-morbidities, > three months apart.

New in @CDCMMWR

cdc.gov/mmwr/volumes/7…
2/ The patients were elderly with multiple chronic health conditions.

They had confirmed infections in a July outbreak at their nursing home- these were described as very mild, w/ only 2 having symptoms at all.

They had at least 4 negative PCR since their first pos tests.
3/ The second outbreak started at the same SNF on October 30th.

5 tested positive again, 3 with known roommate exposures.

7 who were previously infected did not test positive but further details about them (did they have more severe initial cases?) not included.

🧵 1/ So I read this @BostonGlobe story today about what is going to be reopening in Massachusetts on Monday - restaurants will have *no capacity limit* and can host *musical performances*(??)

Hmm interesting.

So I decided to check again what % we have vaccinated #covid19 ...
2/ So we are at 6.2% in terms of people who have received two doses; 16% for those who have received one dose

So...we aren’t even close to where we need to be for vaccinations, we got lucky to see a rapid decline in cases, but now we are rapid reopening

nytimes.com/interactive/20…
3/ I then took a look at the waste water surveillance data, which tends to precede detected cases— possibly a slight uptick here in the last few days?

All this to say: a decrease in cases should still mean—> scale up vaccinations while temporizing spread

🧵1/ So CDC published a couple of outbreak investigations from gyms yesterday— heavy breathing, incomplete mask use, aerosols 🗣 —> superspreading #covid19

But we knew this was risky from a May 2020 outbreak in exercise classes in South Korea already...

washingtonpost.com/nation/2021/02…
2/ This was published in May 2020 in the @CDC_EIDjournal - they found that rigorous exercise was associated w/ transmission whereas low intensity (Pilates, yoga) was not.

I think many of you would remember this.
#covid19
3/ What I’m getting at— why is something that isn’t surprising/that we already somewhat knew being presented as novel?

We already could guess from nearly a year ago that gyms- esp w/ heavy exercise- were risky.

Yet ventilation & aerosol risk only recently being highlighted?

🧵1/ Sometimes when you push for an idea for long enough (#BetterMasks) & when the logic makes sense to you- but you are continuously told by other “experts” (CDC leadership) that it’s not needed; you begin to wonder if you yourself are missing something. #covid19
2/ But- the other factors at play- the political ones- make me think otherwise.

If CDC said “yes better masks are better; yes they protect you more”, they are now on the hook for getting these to people.

But- if they don’t have the bandwidth or political backing to do it...
3/ Then they can’t acknowledge it.

But- because we (many of us) pushed for #BetterMasks incessantly, they probably had to do something.

So they did a study with two masks, which worked better than one mask; two masks is easy bc it’s still on the public to figure it out.

Another @CDCgov report today on #covid19 from unmasked exercise classes

The secondary attack rate of infection from instructors to class participants for classes taught within 1 day of symptom onset was 95% (20 of 21)!

And again here, we have CDC 🗣 about aerosol transmission
2/ Transmission despite 6 feet apart w/ instructors yelling during stationary cycling class #covid19
3/ One of the instructors was teaching kickboxing & personal training - two of the infected participants wore masks and were *still infected*
