CDC: Face Masks Don’t Prevent COVID-19, Study Finds

[Ubeja Vontell]

Yea it's working, my N95 with a surgical(double masks before double masks were "cool") and faceshield with gowns works that I still got covid, but yea it works. But again, keep wearing your mask and go by what someone else tells you what to do, keep being the sheep you are, take care.

Pay attention .,,,,

I know nothing at all about auto mechanics, yep.....don't care, not interested. ok? As we all know a lot of guys are into that stuff, so......when I need one of my vehicles fixed, guess what? No not being a sheep here, ok? just going to have knowledgable people work on something I know nothing about. Ya with me amigo?

Now......when some old dude with over 50 years of experience says.......wear a mask it helps vs this virus........am I a guy with ZERO knowledge about any virus going to challenge him, only an idiot would do that.

Dude, if you can;t figure out the need for a mask you're ******, ok? And wearing a mask ain't nothing at all, no big deal of any kind, a total othing actually,

Bottom line of the report:

At 81-100 days after a state wide mask mandate is put in place they show a 1.8% reduction in cases and a 1.9% reduction in deaths.

Specifically for restaurants that allowed on-premise dining, at 81-100 days after opening up they saw an increase in cases of 1.1% and a increase in deaths of 3.0%.

Cloth face masks in the general population might be effective, at least in some circumstances, but there is currently little to no evidence supporting this proposition. If the coronavirus is indeed transmitted via indoor aerosols, cloth masks are unlikely to be protective. Health authorities should therefore not assume or suggest that cloth face masks will reduce the rate or risk of infection.

CDC study finds about 78% of people hospitalized for Covid were overweight or obese



This doesn't have to do with the original topic, but it is an interesting point.

Bro of course masks dont work at indoor restaurants because people take their mask off to eat. CDC has been saying through the pandemic Restuarants are the hotzones for the virus.

And of course fat folk are at highest risk of being hospitalized but its not like these fatasses asked for a foreign virus to invade their bodies/countries. No 1 expected a China man to eat a bat and spread this virus.

Anyways, the biggest issue I see is people not maintaining social distancing. Wearing a mask alone becomes less effective if you have someone "all up in ya grill" at your local Wal Mart.

Imo the South Koreans were/are a good example of how a country should act during a pandemic. They still suffered casualities but they are a very disciplined people.

And lastly I got CoronaVirus and so did everyone in my house. We wear masks but we also did go to restaurants and family gatherings unmasked (we lacked discipline) but we all recovered just fine (Thank God!) and I ran daily but my sense of smell still comes and goes making food less enjoyable and for a Chicano thats a big deal because we love to eat.

again, keep doing you troll

listen to others vs the actual data that's out there

i'm just stating what was in the study, if you say they don't work in restaurants then tell that to the cdc

there were other studies that I posted that was about masks but you didn't mention anything about those but whatever

but where's the evidence about OAN though that you mentioned in your earlier post?

I remember when you got covid, I'm the one who actually said I think you got it after you listed your symptoms. And thank goodness you and your fam recovered just fine, and so did others, yet even with a 98% recovery rate, shit still hit the fan. Also, you mentioned if you got the China virus that you were going to throw a rock at a panda express window, did you ever do that since you actually did have it?

I think it obvious that masks and social distancing work. The number of cases of the common flu which is also spread by airborne aerosls is down dramatically. I trust Fauci when he says wearing a mask and distancing are important.

Cool man, hope you trusted Fauci when he said it was safe to go vote in person with your mask and social distancing.

Now CDC trying to admit it

This is the referenced study:



Do you understand what the numbers are saying here? The percentages given here are not total numbers of cases or deaths but the change in daily growth rates... an exponential value. For instance a 1.6% increase in daily growth rates would equate 17% more cases after 10 days, 37% more cases after 20 days and 61% more cases after a month and so on... OAN is using that seemingly low 1.1% or 1.5% figure to maybe get folk thinking it's an insignificant difference, but over time it ain't trivial at all.

Puts a slightly different slant on it doesn't it? Not gonna assume that OAN are relying on folk's ignorance of maths / stats here but their headline certainly seems to downplay or even contradict the substance of the report which in fact says quite clearly that mask mandates are effective at reducing spread and that that indoor dining restrictions whilst less significant also play a role.

When you're dealing with exponentials like the the spread of infectious disease the battle takes place at the margins, bringing that R number down by even a few % is the difference between a disease which is growing and one that is stabilised or slowing.

I never said this study was for total numbers of cases or deaths.

OAN reported a story and I shared it. Folks here called OAN fake, I supplied them with other studies that discussed effectiveness of masks, and they came with similar results.

Both your headline and the OAN report suggest that the wearing of masks has a negliable impact on the spread of COVID. This is patently false as is clearly stated by the study referenced in the OAN article.

In fact the OAN article makes several claims which are either outright lies or gross misrepresentations of the findings of the study:

OAN:

In a , the CDC found face masks had a negligible impact on coronavirus numbers that didn’t exceed statistical margins of error.

Study:

Mask mandates were associated with statistically significant decreases in county-level daily COVID-19 case and death growth rates within 20 days of implementation. Allowing on-premises restaurant dining was associated with increases in county-level case and death growth rates within 41–80 days after reopening. State mask mandates and prohibiting on-premises dining at restaurants help limit potential exposure to SARS-CoV-2, reducing community transmission of COVID-19.

P-values <0.05 were considered statistically significant. All analyses were weighted by county population with standard errors robust to heteroscedasticity and clustered by state. Analyses were performed using Stata software (version 14.2; StataCorp). This activity was reviewed by CDC and was conducted consistent with applicable federal law and CDC policy.^��

During March 1–December 31, 2020, state-issued mask mandates applied in 2,313 (73.6%) of the 3,142 U.S. counties. Mask mandates were associated with a 0.5 percentage point decrease (p = 0.02) in daily COVID-19 case growth rates 1–20 days after implementation and decreases of 1.1, 1.5, 1.7, and 1.8 percentage points 21–40, 41–60, 61–80, and 81–100 days, respectively, after implementation (p<0.01 for all) () (). Mask mandates were associated with a 0.7 percentage point decrease (p = 0.03) in daily COVID-19 death growth rates 1–20 days after implementation and decreases of 1.0, 1.4, 1.6, and 1.9 percentage points 21–40, 41–60, 61–80, and 81–100 days, respectively, after implementation (p<0.01 for all)

What is added by this report?

Mandating masks was associated with a decrease in daily COVID-19 case and death growth rates within 20 days of implementation. Allowing on-premises restaurant dining was associated with an increase in daily COVID-19 case growth rates 41–100 days after implementation and an increase in daily death growth rates 61–100 days after implementation.

OAN

The found that between March and December 2020, face mask orders reduced infection rates by 1.5 percent over the rolling periods of two months each. The masks were 0.5 percent effective in the first 20 days of the mandates and less than 2 percent effective after 100 days.

Implying quite clearly that the 1.5% difference was over the entire 2 month span when in fact the study above quite clearly states that this is the change in daily growth rates... an utterly different figure and completely at odds with OANs claims. OAN are grotesquely wrong here whether deliberately or through ignorance and yeah despite the fact that infection and death rates are now slowing people's lives are still on the line.

Your headline is significantly misleading (although of course, no, face masks can't entirely prevent COVID 19) and the OAN report is wildly innacurate. You think maybe it'd be a good idea to fact check this kinda thing before you go spreading potentially lethal misinformation, man?

What I don't like about this study... and maybe this alludes me? I cannot find where there is a separation, a control, for the masks, as opposed to the dining restrictions. How do we know what to attribute to each policy? Is it the social distancing, of which socializing in restaurants is a big part of, or the masks? Since you read the study carefully did you see anything that tells us how to look at each policy on its own merits citizen K?

My own position is that social distancing definitely has an affect on transmission. I wonder about the masks...
