vimesey:Where have I seen this equation before? When evaluating the effectiveness of masks, we want to understand and quantify their effect on the infection probability, Pinf. Assuming that every inhaled single virus (virion) has the same chance to infect a person, Pinf can be calculated by a single-hit model of infection
It is good to see that editors of SCIENCE have finally figured out that there is an "at least one" rule. They should have learned how to apply the rule in this paper Darwinian Evolution Can Follow Only Very Few Mutational Paths to Fitter Proteins. If they had, they could have explained the Weinreich paper and there would be plenty of experimental and empirical evidence to verify the use of the equation this way.Pinf=1−(1−Psingle)^Nv (1) where Psingle represents the infection probability for a single virus and Nv represents the total number of viruses to which the person is exposed (10). Does this equation show that masks are effective? The last paragraph tells when they will be.
Our results have important implications for understanding and communicating preventive measures against the transmission of airborne viruses, including SARS-CoV-2. When people see images or videos of millions of respiratory particles exhaled by talking or coughing, they may be afraid that simple masks with limited filtration efficiency (e.g., 30 to 70%) cannot really protect them from inhaling these particles. However, as only few respiratory particles contain viruses and most environments are in a virus-limited regime, wearing masks can keep the number of inhaled viruses in a low-Pinf regime and can explain the observed efficacy of face masks in preventing the spread of COVID-19. However, unfavorable conditions and the large variability of viral loads may lead to a virus-rich regime in certain indoor environments, such as medical centers treating COVID-19 patients. In such environments, high-efficiency masks and additional protective measures like efficient ventilation should be used to keep the infection risk low. The nonlinear dependence of mask efficacy on airborne virus concentration—i.e., the higher mask efficacy at lower virus abundance—also highlights the importance of combining masks with other preventive measures. Effective ventilation and social distancing will reduce ambient virus concentrations and increase the effectiveness of face masks in containing the virus transmission. Moreover, high compliance and correct use of masks is important to ensure the effectiveness of universal masking in reducing the reproduction number for COVID-19
Since you can't produce the data that masks have been effective, you want me to produce data that masks haven't been effective. Why haven't the institutions that track this kind of data, published their results? It couldn't be that the data shows that there is no significant benefit to the general usage of masks?

vimesey:I have presented as much data as you have presented. By the way, how is that little girl with cancer doing?

vimesey:And you have presented no data. I have something much more than a river in Egypt, I have redemption, something which you don't think you need. I am glad that she is doing well. If you think that I would rather a young girl dies, you would be very wrong.

vimesey:Is that why you don't post the data? There are many things that you don't understand. One of those things is that God determines the number of days of our lives. Your hope is that she lives a long life just to prove me wrong. My hope is that she live long enough to know that Jesus Christ is her redeemer, whether she lives only a short time or a long time. No matter what you say, she will die and so will you.

vimesey:If the data was there, you would post it, but you don't. Yes, we all die no matter what science does. And you better wear your mask to bed so that you won't die.

vimesey:You still haven't posted any data that masks work. When are you going to order people to wear tin foil hats.

vimesey as reported by xongsmith:So you notice that as well in vimesey's post, no data that masks work? xongsmith doesn't need data or experimentation for his scientific research.

Kleinman:Where has descent with modification and adaptation been explained? Kleinman:It's all about descent with modification and adaptation. Vaccines are selection pressures and when you have diversity in the population, vaccines won't be universally effective if resistant variants are in the population. Kleinman:Perhaps so, but I do know how descent with modification and adaptation works. And it is the reason that influenza vaccines have to be changed every year and why Covid vaccines are not 100% effective. Kleinman:Try not to be so mockable. Kleinman:Was the urgency due to fear and overreaction to a perceived threat? I know people that have died after catching influenza. Should all the policies instituted for Covid be instituted for influenza? Vaccines are pretty safe because they undergo extensive testing based on years of experience using these drugs. Fear is not a good reason to discard this experience and push out a vaccine that hasn't been fully tested. Kleinman:Why don't the agencies responsible post the data? Kleinman:Do the math with your own numbers. 0.5%*100,000,000=500,000 people with adverse reactions for every 100,000,000 vaccinated. How many people got COVID and died from the disease (these numbers are questionable because the death rate from cancer, heart disease, and other causes dropped since COVID is being reported). Then you might understand why some people refused the vaccine, the risk-benefit ratio was not good enough for them to take the vaccine. But people like you want these people to lose their jobs and have them locked up because they will spread a contagious disease. Why not fire and lock up those that got the vaccine but still spread the disease?

xongsmith continues to have difficulty posting the data that general usage of masks was effective in preventing the spread of Covid (or any other infectious disease).

vimesey:Where in your quote do you post the data that shows that the general usage of masks was effective in preventing the spread of Covid (or any other infectious disease).

xongsmith still can't post the data that the general usage of masks prevents the spread of Covid or any other infectious disease.

vimesey:From your link: Interpretation The findings of this systematic review and meta-analysis support physical distancing of 1 m or more and provide quantitative estimates for models and contact tracing to inform policy. Optimum use of face masks, respirators, and eye protection in public and health-care settings should be informed by these findings and contextual factors. Robust randomised trials are needed to better inform the evidence for these interventions, but this systematic appraisal of currently best available evidence might inform interim guidance.
And why can't you post the data that shows that the general usage of masks prevented the spread of Covid or any other infectious disease? If you have the data, post it, but you don't have the data. Perhaps you think everyone should wear hazmat suits?

Tanypteryx:I'll do that right after you explain how descent with modification and adaptation works. Show us how well-trained a biologist is in science and mathematics. And Tany can't post the data that shows that the general usage of masks prevents the spread of Covid or any other infectious disease either.

Tanypteryx:I don't say that Tany, I say that you are the typical biologist that doesn't understand how biological evolution works. Of course, you could prove me wrong by explaining how descent with modification and adaptation works. But to do that, you would need some scientific and mathematical training which you haven't gotten. And you still don't post the data that shows that the general usage of masks prevented the spread of Covid or any other infectious diseases.

Tanypteryx:Tany can't post any data that shows that the general usage of masks prevented the spread of Covid or any other infectious diseases, nor can he post any quotes of me where I've said anything that he claims I've said. Too bad Tany can't explain how descent with modification and adaptation works, but that should be expected, he was trained as a biologist.
