“The baseline assumptions for the model were that peak infectiousness occurred at the median of symptom onset and that 30% of individuals with infection never develop symptoms and are 75% as infectious as those who do develop symptoms. Combined, these baseline assumptions imply that persons with infection who never develop symptoms may account for approximately 24% of all transmission. In this base case, 59% of all transmission came from asymptomatic transmission, comprising 35% from presymptomatic individuals and 24% from individuals who never develop symptoms. Under a broad range of values for each of these assumptions, at least 50% of new SARS-CoV-2 infections was estimated to have originated from exposure to individuals with infection but without symptoms.”

wow. I wonder what would happen if everyone wore masks in public and indoors - all those asymptomatically ill people would be wearing masks and not transmitting the 50 %+ cases that there are responsible for spreading. Can yoh imagine if we had 50 % fewer cases? |
Masks help control spread full stop: https://www.forbes.com/sites/johndrake/2022/02/04/the-real-world-effectiveness-of-face-masks-against-covid-19/amp/ “Statistical analysis showed that the odds of infection were about half for people who reported wearing a mask in public compared with people who didn’t. (Results of this study are reported in terms of “odds ratios” which are related to relative risk, but not quite the same thing.) For people who wore masks “all of the time” (instead of “some of the time” or “most of the time”) the estimated effect was even more significant.” |
Mask mandates =/= masking. Pay attention to language. People who are motivated to wear good masks properly (for whatever reason) should do so. Mandates = requiring people who don’t want to wear masks or who suck at wearing masks (children) wear masks = ineffective. |
You missed it— I was responding to a poster who wrote “masks don’t work”. Nothing about mandates. Always best to clear up misinformation, don’t you think. |
Yes, like people testing positive for covid, but asymptomatic, and posting here on DCUM that they think it's OK to go out. |
I never had COVID before last week either, but I got infected along with my family and many others that we know who are now getting it for the first time. Be careful. You may think you’re lucky but this variant is no joke. I wish I had gotten an earlier variant because I probably would have been a lot less sick. |
Forbes? GTFO, I am a scientist. I read actual studies. All of the studies on masking are confounded because the places where mask mandates exist, and the people who choose to wear masks, are fundamentally different in terms of other actions they take to mitigate covid. |
Puhleeze. You’re no more a scientist than I’m the Queen of England. Besides, if you read the article, they are quoting from multiple scientific studies. |
We aren't talking about the masks, we are talking about the mandates. PP wants to bring back mandates. Mandates are useless, unless you plan to lock everyone down again Shanghai style. Covid will continue to spread in every situation where masks aren't required; in other words, mandates won't change the curve. You can prevent YOURSELF from getting sick by avoiding crowds, wearing N95, etc. |
Dp. Your article is garbage and even the author knows it. The author states several times that this is their “opinion” of what the study concluded and, to their credit, lays out several of the problems with the study. As the pp stated, people who claim to wear their mask “all the time” are probably being cautious in other ways as well. It is extremely difficult to measure the effectiveness of masks in a real population because people are unpredictable. Wear your mask all you want, but you have zero real world studies showing that mask mandates have improved Covid outcomes. |
My life would be exactly the same. |
Masks are over. No one normal is going back to masking. Luckily you can choose for your self |
Well google your own article then. There are multiple ones out there that say the same thing. What I’m really looking forward to are the retrospective studies that will be published years from now analyzing this pandemic. Will be a fascinating read, I’m sure. |
