    Re: Sweden

    While they didnt have a general mask mandate they recommended them for public transport.

    And according to this were mandatory in healthcare settings.

    "Starting from last week, 17 of Sweden's 21 administrative regions reintroduced face mask requirements in hospitals and nursing homes."

    You know what, I don't need your opportunity, but thank you for being so considerate.

    I am a rational person, despite what you think, and I don't need your approval to think otherwise. I can see that the covid measures were pointless, and I don't care how well intentioned you seem to think they might have been.

    The main thing for me now is that covid restrictions and masks are gone in Ireland, and they're gone or going all over the world. They're a hateful burden, and I don't care about any science or statistics around them.

    The more people that accepts masks and restrictions now makes it easier for governments to impose such restrictions again in the name of "public health".

    The genie is out of the bottle, very hard to get it back in....

    Take your chances with covid and everything else that comes at you, just like we have done up to now. If you narrowly focus on one topic you miss everything else that is coming at you.

    Your statement here says it all....

    They're a hateful burden, and I don't care about any science or statistics around them.

    It is a combination of hyperbole and ignorance of the facts. Just because you dont care about the facts, thankfully the vast majority do and will follow public health guidance when asked.

    Proof that masks were really a waste of time! 

    Here is part of the conclusion in the report.

    Medical/surgical masks compared to no masks

    We included 12 trials (10 cluster‐RCTs) comparing medical/surgical masks versus no masks to prevent the spread of viral respiratory illness (two trials with healthcare workers and 10 in the community). Wearing masks in the community probably makes little or no difference to the outcome of influenza‐like illness (ILI)/COVID‐19 like illness compared to not wearing masks (risk ratio (RR) 0.95, 95% confidence interval (CI) 0.84 to 1.09; 9 trials, 276,917 participants; moderate‐certainty evidence. Wearing masks in the community probably makes little or no difference to the outcome of laboratory‐confirmed influenza/SARS‐CoV‐2 compared to not wearing masks (RR 1.01, 95% CI 0.72 to 1.42; 6 trials, 13,919 participants; moderate‐certainty evidence). Harms were rarely measured and poorly reported (very low‐certainty evidence).

    Its proof of no such thing... as explained below.

    One of studies cited showed there was no benefit if staff in a hospital wore a reusable cloth mask as PPE versus flu.

    We knew that already. How is that relevant to covid mask mandates?

    One of the other studies showed regular mask wearers in Denmark had fewer cases than non mask wearers but due to low level of covid significant case numbers were not hit in the study.

    The advice from health authorities was always not to rely on such masks as PPE.

    That does mean they dont help to reduce transmission from an infected person.

    This is the nub of it. Masks do have an impact if there is low levels of virus circulating. Once the virus is everywhere masks are not useful as there are too many exposure events. This was proven everywhere that had a mask mandate without a lockdown.

    If you are getting a bus everyday your number will eventually come up.

    Different odds if you have vulnerable people needing to access essential services occassionally during a breakout.

    And measures like masks and distancing improve those odds.

    Almost everyone's number did eventually come up, so point proven.

    Masks did not stop the spread they had very limited affect, they were effectively useless.



  • Registered Users Posts: 27,869 ✭✭✭✭odyssey06


    Effectively useless?

    Or very limited effect?

    In the same post you cant even keep your story straight and resort to strawman argument to have to make your case.

    Rather important everybodys number didnt come up at the same time. And bought time to rollout vaccines etc

    So nope. No point proven.

    A guy that has been widely discredited for constantly misinterpreting data is not a great argument really.

    Masking and vaccines was to get you back out spending money.

       He makes an excellent point here, saying how he used to be pro mask but he has seen the data and evidence and so has changed his mind.


       A lot of the stubborn people that are just doubling down could do the same..

    The study John Campbell refers to is flawed

    Here's some interesting reads on that study that he refers to

    The study John Campbell refers to is flawed

    And you feel qualified to state that like its a fact, yes?



  • Registered Users Posts: 9,925 ✭✭✭normanoffside


    So the study concludes we should have been wearing respirator masks but that the ones we were wearing (cloth and paper masks) had little effect?

    There was no respirator mandate so I don't see what is wrong in saying that Mask Mandates were ineffective.

    No. Mask mandates were never about direct protection of the wearer by non respirator masks. It was always stressed you should not rely on them as PPE. This has been pointed out dozens of time on the threads from the when mandates were first brought in here.

    For much of the pandemic there was a shortage of respirator type masks and priority for them was as PPE for health care workers.

    Mask mandates were about limiting droplets FROM an infected person. Masks as barriers not PPE.

    :D :D :D :D !! John Campbell!!! again not a reliable source for anything but misinformation and misinterpretation.

    Why not take a look at the flaws in the Cochran report while you are at it

  • Registered Users Posts: 1,555 ✭✭✭Sconsey


    Experts in the field of epidemiology have pointed out the flaws, you don't need a qualification to understand that.



  • Registered Users Posts: 5,405 ✭✭✭CalamariFritti


    And other experts in the field have produced the study.



  • Registered Users Posts: 1,555 ✭✭✭Sconsey


    No they produced a review by pooling multiple existing studies, Cochrane is not a new study. You really should read more into it, here are just some of the reasons why it is not what you think it is (copied from https://yourlocalepidemiologist.substack.com/p/do-masks-work#%C2%A7then-the-cochrane-review-was-published-and-took-social-media-by-storm)......


    If done correctly, Cochrane reviews are incredibly powerful and typically respected in the scientific field.  

    This specific review included studies on non-pharmaceutical interventions, including masks. If we just look at the mask studies, the Cochrane review included 12 studies. But the details matter, as these studies: 

    • Only included randomized control trials (RCTs). This is typical for meta-analyses as RCTs are the “gold standard” for scientific questions. But these RCTs had a number of problems and, given the limited number of RCTs on COVID-19, do not represent the totality of evidence (i.e., see all studies above). 
    • Combined different viruses. When a virus is less contagious, an effect is harder to detect. Many of the RCTs evaluated influenza, which is far less contagious than COVID-19. This means that if we combine them, the impact of masks may be underestimated. (Another scientist, separate from this review, removed the flu studies and reran the meta-analysis. He found masks protected against SARS-CoV-2.)

    Source: @gidmk

    • Combined settings. Studies ranged from suburban schools to hospital wards in high‐income countries, crowded inner city settings in low‐income countries, and an immigrant neighborhood in a high‐income country.
    • Only asked one question. Does wearing a mask protect me? This ignores other important questions.




  • Registered Users Posts: 5,405 ✭✭✭CalamariFritti


    Thanks and yes I do know that it is a meta study or a compilation if you like.

    But IMO we're really back to the same old argument. If an iron clad mask benefit could be derived from studies then this would have happened. But we're still in the same ballpark, may have, may not have. The case for masks just was never strong enough IMO for the pro-mask fraction to claim 'masks work, case closed'. We've seen it from the start when it went 'masks won't work' then 'masks work'. It was never like 'seatbelts work' or 'not smoking helps' or anything like such a case closed thing, not even remotely.

    One way or the other thats still the same thing I'm getting from this. And considering such weak evidence it never justified the boohaa that was made about them. Never mind mandates.



  • Registered Users Posts: 27,869 ✭✭✭✭odyssey06


    Mask mandates were introduced for indirect protection, not direct protection.

    It is very difficult in practice to establish 'iron clad benefit' of such indirect effects. When eg passive smoking bans were brought in here in pubs in Ireland it was not on the basis of the type of iron clad benefit you seem to seek for masks here. That is why public health experts also look at lab studies, example case studies and assess what data from other studies is of value.

    Many of the studies cited in this meta study do not even really relate to mask mandates.

    It's not a pro-mask 'faction', it was the considered opinion of the experts at every major health authority in the world. And those experts have seen all these studies. That's why it is valid to say, the case has been looked at and masks work - that is the expert scientific consensus and they are not picking it out of thin air.

    I disagree tbh. There was a very strong political element to the mandate and then to the debate about them too. And like it is every time when politics gets involved things get murky and dogmatic. Before we knew it people who questioned were branded selfish and deniers and Trumpists and off we went. Which was a hallmark of all things covid. You either followed unquestionably or you were one of them arseholes, very polarised in no time.

    A few observations at this point of thread comments.

    More than one poster has used the word “proof,” along with its variations. There is no proof in the scientific method, only suggestions from the analysis of data, often informed by theories. These suggestions and theories may be useful towards informing COVID-19 remedy policies (e.g., mask wearing, social distancing, vaccinations, personal hygiene, etc) so long as they continue to receive a preponderance of statistical support that suggests their efficacy and practicality.

    A major problem with drawing conclusions at this point, as so many have in this thread, regarding COVID-19 (including mask wearing for Covid in particular) is that there has only been time for short, and now midterm scientific studies. In five and more years from late 2019 there will have been enough time for longitudinal studies to have occurred, hopefully several for comparison purposes to estimate their reliability and validity.

    Such longitudinal studies may also be able to suggest potential remedies for evolving virus variations, whereas short and midterm studies may be problematic due to time limitations.

    For these reasons, and other methodological considerations (some cited above by other posters), I would be very cautious about using the above meta analysis to suggest that masks may be useful, or not, towards the mitigation of COVID-19. There has not been enough time to longitudinal study COVID-19 in particular.
