the cloth masks *did* actually help during the Spanish Flu, we have records supporting it, and that's one of the reasons we started wearing masks in the operating theater
@feld There are tons of airborn diseases that are not over yet, but nobody wore masks before COVID. Well, actually people tried using them during Spanish flu, but to no avail which was absolutely logical.
This masks BS was just an attempt to establish some sort of dresscode for the so called “new normality”.
> In 1905, ALICE HAMILTON (1869–1970), a Chicago physician, proposed that scarlet fever was transmitted through droplet infection and recommended doctors wear masks at the time of surgery because of heavy droplet transmission from the mouth and nose while talking and teaching. This may have been the first recommendation that surgeons wear masks.
original suggestion predated Spanish Flu by only a decade
The high risk of bias in the trials, variation in outcome measurement, and relatively low adherence with the interventions during the studies hampers drawing firm conclusions
alright, now that the point has been made let's stop shitting on the dude and find a way to encourage him to be more careful about interpreting these studies incorrectly which just drags you down into a conspiracy theory hole
@freemo@post@feld yes that's a very non-conclusive systematic review. The authors conclude that the variability in the studies and the low adherence with the masking interventions means they can't say with any confidence whether the effect size estimate is at all accurate. That's a great paper to cite to show we don't actually know if masks work!
The review you posted clearly did not state that masks were ineffective. It said we dont have strong confidence (proof) they are effective and that more studies need to be done to answer that question…
You really do just read what you want to read dont ya?
You are clearly not used to this kind of papers, it is normal to use cautious sentences to this extent and you should focus on the results instead:
“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).
We pooled trials comparing N95/P2 respirators with medical/surgical masks (four in healthcare settings and one in a household setting). We are very uncertain on the effects of N95/P2 respirators compared with medical/surgical masks on the outcome of clinical respiratory illness (RR 0.70, 95% CI 0.45 to 1.10; 3 trials, 7779 participants; very low‐certainty evidence). N95/P2 respirators compared with medical/surgical masks may be effective for ILI (RR 0.82, 95% CI 0.66 to 1.03; 5 trials, 8407 participants; low‐certainty evidence). Evidence is limited by imprecision and heterogeneity for these subjective outcomes. The use of a N95/P2 respirators compared to medical/surgical masks probably makes little or no difference for the objective and more precise outcome of laboratory‐confirmed influenza infection (RR 1.10, 95% CI 0.90 to 1.34; 5 trials, 8407 participants; moderate‐certainty evidence). Restricting pooling to healthcare workers made no difference to the overall findings. Harms were poorly measured and reported, but discomfort wearing medical/surgical masks or N95/P2 respirators was mentioned in several studies (very low‐certainty evidence).
One previously reported ongoing RCT has now been published and observed that medical/surgical masks were non‐inferior to N95 respirators in a large study of 1009 healthcare workers in four countries providing direct care to COVID‐19 patients.”
Poverty rate for whites in USA is ~9% and it's ~20% for blacks.
You don't think a higher concentration of impoverished people is going to cause some shooty-shooty violence especially when these people get clustered together in a city?
Because you're comparing by the whole not by per capita? Why would you even begin comparing that way without populations being 100% equal?
And then you have to consider completely different living conditions of where poor white people live vs poor black people
There are so many factors here that lead to different living experiences and different outcomes you can't point to a single root cause.
"Why then don't poor black people choose to live like poor white people"
Well I don't know, maybe because they used to live like poor whites during Reconstruction but then in the early 1900s we blamed the economic hardships on the black people who spread throughout the country and decided to burn down their homes and lynch them if they didn't get out of their counties so they all ran to inner-city communities which created the typical American ghettos? Just like we did 20 years earlier to the Chinese which created Chinatowns?
it's actually not, the strain just changed over time to be less and less harmful. The same influenza that goes around every year is directly linked to its ancestor, the Spanish Flu
> "All human-adapted influenza A viruses of today — both seasonal variations and those that caused more dramatic pandemics — are descendents, direct or indirect, of that founding virus," notes Dr. Taubenberger, Senior Investigator in NIAID’s Laboratory of Infectious Diseases. "Thus we can be said to be living in a pandemic era that began in 1918."
First, let’s be clear. The premise that surgeon’s wearing masks serve as evidence that “masks must work to prevent viral transmission” is a logical fallacy that I would classify as an argument of false equivalence, or comparing “apples to oranges.”Although surgeons do wear masks to prevent their respiratory droplets from contaminating the surgical field and the exposed internal tissues of our surgical patients, that is about as far as the analogy extends.
@feld this just reminded me that a zombie game called h1z1 came out like right after the h1n1 incident lmao, can you imagine someone making a "coZid-19" game? XD
