Coronavirus COVID-19

[kalm]

Danish study on mask effectiveness.

Abstract

Background:
Observational evidence suggests that mask wearing mitigates transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is uncertain if this observed association arises through protection of uninfected wearers (protective effect), via reduced transmission from infected mask wearers (source control), or both.

Objective:
To assess whether recommending surgical mask use outside the home reduces wearers' risk for SARS-CoV-2 infection in a setting where masks were uncommon and not among recommended public health measures.

Design:
Randomized controlled trial (DANMASK-19 [Danish Study to Assess Face Masks for the Protection Against COVID-19 Infection]). (ClinicalTrials.gov: NCT04337541)

Setting:
Denmark, April and May 2020.

Participants:
Adults spending more than 3 hours per day outside the home without occupational mask use.

Intervention:
Encouragement to follow social distancing measures for coronavirus disease 2019, plus either no mask recommendation or a recommendation to wear a mask when outside the home among other persons together with a supply of 50 surgical masks and instructions for proper use.
Measurements:

The primary outcome was SARS-CoV-2 infection in the mask wearer at 1 month by antibody testing, polymerase chain reaction (PCR), or hospital diagnosis. The secondary outcome was PCR positivity for other respiratory viruses.

Results:
A total of 3030 participants were randomly assigned to the recommendation to wear masks, and 2994 were assigned to control; 4862 completed the study. Infection with SARS-CoV-2 occurred in 42 participants recommended masks (1.8%) and 53 control participants (2.1%). The between-group difference was −0.3 percentage point (95% CI, −1.2 to 0.4 percentage point; P = 0.38) (odds ratio, 0.82 [CI, 0.54 to 1.23]; P = 0.33). Multiple imputation accounting for loss to follow-up yielded similar results. Although the difference observed was not statistically significant, the 95% CIs are compatible with a 46% reduction to a 23% increase in infection.

Limitation:
Inconclusive results, missing data, variable adherence, patient-reported findings on home tests, no blinding, and no assessment of whether masks could decrease disease transmission from mask wearers to others.

Conclusion:
The recommendation to wear surgical masks to supplement other public health measures did not reduce the SARS-CoV-2 infection rate among wearers by more than 50% in a community with modest infection rates, some degree of social distancing, and uncommon general mask use. The data were compatible with lesser degrees of self-protection.

In case I missed the point of this, it appears to support something we already know, masks are not worn as protection from Covid. Masks are primarily worn to reduce the spread by someone that is infected.

Yep. And other measures further reduce the risk.

We'll fuck. Waiting on results from LIlCCU's test. DHEC should respond within 72 hrs.

Backstory - We avoided a party a few weeks ago b/c we didn't know most of the people and knew a few of the attendees weren't careful at all regarding COVID. Found out this week that almost every single person who attended has now tested Positive and some of their children have as well. Children weren't invited to the party. Lil CCU plays with 2 of the kids that tested positive and has started to complain about not feeling well.

Thanks, Obama!

A 50% reduction in my chances of being infected is pretty good.

I'm surprised if it's 50% (the conclusion says "did not reduce...by more than 50%" so without having read your full link I'm not certain what effectiveness they claim). That's better than I'd have expected.

My feelings on masks has been that they are relatively ineffective but if it is only 10% effective (or whatever number you want to pick), and distancing is 5% effective, and so on it can add up to slow down the transmission while a vaccine and/or better treatments are developed. I've never understood why both extremes act as though it's all or nothing with masks.

We teach our kids to cover their mouth when they sneeze/cough. Why wouldn't having some form of mask cause turbulence, slow velocity, etc. of the stream that has some minor beneficial effect? Should we quit bothering to cover our mouths when we cough?

It's such a minor inconvenience to put one on to run into the store. Why not?

A wedding in the country around nearby Ritzville, Wa with 300 attendees now has 40 infected so far, has spread to neighboring counties, and caused at least two other outbreaks.

It exceeded the social gathering size restriction by 10.

Look at all the freedom they’re spreading.

Agreed. It'll likely bear out that anything less than an N95 rated mask is useless. My favorite analogy when people harp on masks is that they are like using a chain link fence to catch a mosquito.

Agreed with “to a point” or are they useless? What science are you basing this off of?

I like the analogy of two guys pissing while wearing pants and not wearing pants.

(No homo)

I like the analogy of trying to catch mosquitos with a fishing net..

Agreed, masks aren't terribly effective, but they are still better than nothing, and it's really not that hard to wear one, so why not.

40 cases means nothing. How many deaths? How many serious cases? Hospitalizations?

What a useless article. Pandering fear porn that proves nothing.

Another record for number of Covid deaths in Minnesota again today.

I don’t know. It just happened 10 days ago. Just like we argued months ago, cases drive the other two by 3-5 weeks.

You find it useless because it doesn’t fit your narrative.

Btw...in case you think I’m not sympathetic to the economics, my oldest friend’s coffee shop which he and his wife poured everything into the last 13 years is closing due to the latest lockdown.

No, they don’t necessarily. If it’s 40 “cases” but they’re mostly asymptomatic, then it’s literally a non-event. If all 40 had mild symptoms, then it’s a non-event. If all 40 are in the hospital on ventilators, well then we might have something.

[SeattleGriz]

Our farm partner just passed away from COVID. Heavy drinker and had diabetes.

You get rid of the comorbidities and your chances improve dramatically.

40 cases even if all asymptomatic means 40 more cases that can be spread. At some point you end up with hospitals compromised and increased deaths.

Like it or not, this is what causes more lockdowns. Clearly not enough people have learned that yet.



Wait...didn’t we have this debate in the spring?

Let us all hope she tested negative and all is well .

Yes, “can be”. The question is, IS IT? Because otherwise, it’s just fear porn.

I know....wait two weeks.

I have some charts and graphs to show you that would make Skelly jealous.

Do you ever get tired of being wrong all the time?

Are they exponential graphs?

Hope everything will be fine, and fortunately for you the odds are extremely in your favor that Lil CCU will be just fine.

A class at my kids' daycare had an assistant come down with symptoms and they closed that class and notified everyone via email while they await test results. When I picked up my kid yesterday, they asked if I saw the email and I said yes and that I have no concerns as all of 2 kids in the state of CA have died with/of the China Virus. I then told my kid to go jump in some muddy puddles before getting in the car and going home. Life goes on.

Thanks. I'd be more worried about the lasting effects from COVID. Rose is pretty strong so I'm not worried. DHEC does free testing and it took all of 30- 40 minutes to drive to the site get the test and then drive home.

Personally, I'm sick and tired of the masks, the worry, the panic, everything. On top of election fatigue, i've got pandemic fatigue. I'm worn out. I have no bandwidth left to give to anything of importance.

That's what they want. Shut up and obey.

We all are.

Just listened to Rogan interview with Yale University professor and physician, Nicholas Christakis. Interesting skill set of medicine, sociology, and networking systems. It’s a brief recap of how we got here and what to expect going forward. Not all bad and conditions can improve for the better depending on governmental and citizen’s actions. But as he said, right now we are only at the end of the beginning with this (meaning all of the effects). He thinks as late as 2024 before things are “normal” from an economic standpoint. He’s predicting 20% of those infected will have a permanent disability from the virus.

<12 million known cases
60-120 million probable cases (known cases x 5 to 10)

Probably going to be 150-200 million cases in the US by the time this is over. I don‘t buy 20% of that (30-40 million) will have disabilities, when probably 80%-90% of cases we never even know about..

That’s of course based on preliminary numbers and understanding of the disease which could change. But I know they have seen organ damage asymptomatic patients, months after infection. Just another in a long line of possibilities.
