So you see, surgical masks will only stop large particles or droplets, but that becomes irrelevant because as my previous article stated, those large droplets then evaporate and become free floating viral particles which are airborne and can remain suspended in the air for many hours.Surgical masks as source control
We were able to identify only two household studies in which surgical masks were worn by the index patient only, as source control.24,25 Neither of these found a significant impact on secondary disease transmission, although both studies had important limitations.
Clinical trials in the surgery theater have found no difference in wound infection rates with and without surgical masks.26-29 Despite these findings, it has been difficult for surgeons to give up a long-standing practice.30
There is evidence from laboratory studies with coughing infectious subjects that surgical masks are effective at preventing emission of large particles31-34 and minimizing lateral dispersion of cough particles, but with simultaneous displacement of aerosol emission upward and downward from the mask.35
There is some evidence that surgical masks can be effective at reducing overall particle emission from patients who have multidrug-resistant tuberculosis,36 cystic fibrosis,34 and influenza.33 The latter found surgical masks decreased emission of large particles (larger than 5 µm) by 25-fold and small particles by threefold from flu-infected patients.33 Sung37 found a 43% reduction in respiratory viral infections in stem-cell patients when everyone, including patients, visitors, and healthcare workers, wore surgical masks.
In sum, wearing surgical masks in households appears to have very little impact on transmission of respiratory disease. One possible reason may be that masks are not likely worn continuously in households. These data suggest that surgical masks worn by the public will have no or very low impact on disease transmission during a pandemic.
There is no evidence that surgical masks worn by healthcare workers are effective at limiting the emission of small particles or in preventing contamination of wounds during surgery.
There is moderate evidence that surgical masks worn by patients in healthcare settings can lower the emission of large particles generated during coughing and limited evidence that small particle emission may also be reduced
My post was in response to your original question.I dont know if you've followed any of my other threads, but my position has always been that regular medical masks which most people are currently wearing arent making any difference. Wearing of N95 masks is whats needed.
And now we have a Toronto Star article posted yesterday that appears to corroborate what I've been saying all along.
Have a look: https://outline.com/MBK2Bg
I quote the relevant parts:
So in other words, if you work in a hospital and you are not in close contact with infected patients a surgical mask is fine.
However, if you ARE in close contact with infected patients N95 masks are a must
Its not irrelevant at all because most people are not wearing N95 masksMy post was in response to your original question.
"Today Texas had a low of just 1,400 cases. Ontario had over 4,400 cases.
Texas population is 29 million people. Ontario has about 15 million peeps.
So we had 3 times as many cases despite having only half of Texas population.
Explain that, you left-wing geniuses"
I posted an article that explained the answer to your question.
You reply with a post about N95 masks, Irrelevant to the current thread.
Signed by 17 Canadian and international researchers, physicians and academics, the complaint letter says the “weight of historic and contemporary evidence” points to surgical masks as providing “little to no protection from inhalation of small infectious particles
While transmission theories initially focused on respiratory “droplets” that spread to people and surfaces through things like coughing or sneezing, growing research has found strong evidence for tiny aerosols that can travel on air currents for hours. That increasingly accepted airborne transmission theory has been linked to a call for N95 respirators for health-care workers
There you have it. The debate is over, you've all lostNurses in Ontario commonly wear N95 masks during routine patient care since the province gave them an option last October
I believe that I did post this before in your N95 thread that I agree that 95 masks work better than surgical or non medical mask because they are designed to be, different levels of protection for different levels of hazards. But for the general public they would not be as effective because they would not be properly worn thereby reducing their effectiveness. We can't get people to handle and wear non medical masks properly, do you reasonably believe the general public will train themselves in the proper use of N95 masks? Non medical masks have been proven to be about 70% effective in reducing respiratory droplets, combined with physical distancing, this stops the spread. An ill fitted N95 mask provides about the same level of protection as a non medical mask properly worn. How many times when you have been out and seen people with N95 masks on and they haven't even pinched the nose piece?I dont know if you've followed any of my other threads, but my position has always been that regular medical masks which most people are currently wearing arent making any difference. Wearing of N95 masks is whats needed.

So you are saying that N95 mask use is responsible for the current case rate inAnd I want to repeat what study in TorStar article said: https://outline.com/MBK2Bg
There you have it. The debate is over, you've all lost
Now reading this I have no idea what you are trying to say, is it that it is relevant because the case rate has not surged in Texas because people are not wearing N95 masks?Its not irrelevant at all because most people are not wearing N95 masks
No, I'm saying most people wear surgical masks and not N95 masks.So you are saying that N95 mask use is responsible for the current case rate in
Texas? I'm not sure what your point is. Could you please clarify
I now accept your defeat (since you have nothing constructive to add to the debate).Phil, relax, calm down! You're ranting and seemingly coming off unhinged. Take a chill pill and post a new sig pic please! I feel like I've repeated enough and need a change. Thanks!
Defeat my ass!! I just can't be bothered with you because I think you're trolling!!!! Nobody can be this dense and honestly keep arguing when they are proven wrong over and over and over.I now accept your defeat (since you have nothing constructive to add to the debate).
Also I am perfectly calm. I just enjoy kicking Lefties ass
-----------> N95 mask

Surgical masks have made zero impact in new case rates, whether thats here in Ontario, or in Texas, or in any other part of the world.
What I'm saying if you really wanna make a dent into the pandemic people need to wear tight-fitting N95 masks.
And even thats not 100% because the virus can enter through the eyes, but its at least better than those flimsy surgical masks most people wear
Anti-maskers throwing stats they find on mask efficacy, but who has ever said wear masks only? It's always been just one part of recommended steps to stay safe.if you are wearing a mask, physical distancing and people are washing their hands, it can not enter through another persons eyes, no transmission no infection.
LOL....clearly you dont own any N95 masks.I believe that I did post this in post #206 that I agree that 95 masks work better than surgical or non medical mask because they are designed to be, different levels of protection for different levels of hazards.

I'll put it wherever I wantThis should stay in your N95 thread and not deflect from the original question
You (and all your other mindless drones) lost the debate. Admit it!!Defeat my ass!! I just can't be bothered with you because I think you're trolling!!!! Nobody can be this dense and honestly keep arguing when they are proven wrong over and over and over.
First- I am well trained and am fitted for masks at least every two years for my job. Just did refresher training yesterday on fitment, requirements for different levels of use and go for a refit on my 7700 on May 1st.LOL....clearly you dont own any N95 masks.
The instructions on how to fit them properly are on the back of the box, and I have posted them many times
False!
I repeat what the study in TorStar article said: https://outline.com/MBK2Bg
I'll put it wherever I want
Thats horseshit. I wear N95 masks every day, and the instructions on the back of the box are as simple as day.First- I am well trained and am fitted for masks at least every two years for my job. Just did refresher training yesterday on fitment, requirements for different levels of use and go for a refit on my 7700 on May 1st.
The respirators I use are the 3m designed TR-300n respirator and the 7700 series by Honeywell.
I use more P95 masks than I do N95 or the respirators but I wear them depending on what the situation calls for, usually averaging around 30 hours a week. The instructions on the box are basic and as I said it is obvious when you see the general public that they are being used improperly, as evidenced here, some people just can't comprehend what they are reading
And I will counter that with latest study which says surgical masks dont do shit.Second- You are wrong my statement on efficiency of non medical masks is true.
"Although the surgical mask as a control sample possesses the highest efficacy, the vacuum cleaner bag, tea towel, and cotton mix also showed filtration efficiency of higher than 70%." ie. non medical mask.

Whats good for the goose should be good for the ganderThird- From your article " That increasingly accepted airborne transmission theory has been linked to a call for N95 respirators for health-care workers"
Read the sentence, it doesn't say "That increasingly accepted airborne transmission theory has been linked to a call for N95 respirators for everyone"
You cant distance on a crowded streetcar, bus or subway either.And again reread the thousands of posts on this subject, masks are to protect the people around the wearer, not to provide protection for the wearer.
This is done by distancing which cannot be done in a healthcare setting which is what the article is stating
I guess when you cherry pick. Ignore all alternative evidence. Take statements that completely misapply the conclusion to areas they don't apply. Also completely ignore any corrections that everyone else is giving you it could seem like you are winning.You (and all your other mindless drones) lost the debate. Admit it!!
