CDC guidelines say wearing a mask during prolonged exposure to coronavirus won't prevent possible infection
Guidelines from the Centers for Disease Control and Prevention state that those who come in close contact with someone with the coronavirus for more than 15 minutes could spread the virus regardless of whether either party wears a mask.
“Wondering what @cdcgov really thinks about masks? Their guidance on quarantining after exposure to someone with #covid explicitly states whether the infected OR exposed person wore masks doesn’t matter,” former New York Times reporter Alex Berenson tweeted Sunday...
...The CDC states on its Public Health Guidance for Community-Related Exposure page that those who come in close contact with people showing COVID-19 symptoms or someone who has tested positive for the virus can spread the infection whether or not they are wearing masks.
CDC states that "data to inform the definition of close contact are limited." Factors "to consider" when defining close contact are duration of exposure, proximity to an infected person, and whether or not that person is presenting symptoms. Data for what a prolonged exposure is are iffy; however, longer than 15 minutes can be considered an operational definition, according to the CDC.
“This is irrespective of whether the person with COVID-19 or the contact was wearing a mask or whether the contact was wearing respiratory personal protective equipment (PPE),” the CDC states....
CDC Study Finds Overwhelming Majority Of People Getting Coronavirus Wore Masks
A Centers for Disease Control report released in September shows that masks and face coverings are not effective in preventing the spread of COVID-19, even for those people who consistently wear them.
A study conducted in the United States in July found that when they compared 154 “case-patients,” who tested positive for COVID-19, to a control group of 160 participants from health care facilities who were symptomatic but tested negative, over 70 percent of the case-patients were contaminated with the virus and fell ill despite “always” wearing a mask.
“In the 14 days before illness onset, 71% of case-patients and 74% of control participants reported always using cloth face coverings or other mask types when in public,” the report stated.
In addition, over 14 percent of the case-patients said they “often” wore a face covering and were still infected with the virus. The study also demonstrates that under 4 percent of the case-patients became sick with the virus even though they “never” wore a mask or face covering.
Despite over 70 percent of the case-patient participants’ efforts to follow CDC recommendations by committing to always wearing face coverings at “gatherings with ≤10 or >10 persons in a home; shopping; dining at a restaurant; going to an office setting, salon, gym, bar/coffee shop, or church/religious gathering; or using public transportation,” they still contracted the virus...

I haven't had time to study this, but the conclusions from your main stream media sources look like garbage to me. The researchers took about 300 people who showed up at an outpatient facility reporting symptoms of Covid. About half of them tested positive for Covid and the other half tested negative.
What they concluded, those who tested positive were twice as likely to have dined out at a restaurant as those who tested negative. Obviously those people who tested positive and ate out were not wearing masks when they were eating. The researchers made no conclusions with respect to masks. What they did say --
What are the implications for public health practice?
Eating and drinking on-site at locations that offer such options might be important risk factors associated with SARS-CoV-2 infection. Efforts to reduce possible exposures where mask use and social distancing are difficult to maintain, such as when eating and drinking, should be considered to protect customers, employees, and communities.
Yes, the people who tested positive were only slightly less likely to report using masks all the time than those who tested negative.
All the people in the study knew their test results before they told the researchers whether they wore masks.
What you fail to appreciate is that the people who tested positive were more prone to lie to the researchers or delude themselves about how often they wore masks. I see this in a buddy who contracted Covid who claims he was very careful about wearing masks and avoiding exposure, and it's bull shit because he was walking around without one all the time.
And the people who exhibited symptoms but tested negative are hypochondriacs like me. We actually do wear masks and go to the doctor to get tested for Covid every time we have a sniffle. We're more likely to wear something like an N95 or KN95 mask than a one layer cloth mask.
Maybe this is easier to understand.
Two people go into the doctor and both think they've got the clap. One tests positive and one tests negative. Both of them tell the public health official afterwards they always wear condoms. Which one are you more likely to believe?
You don't have a huge sample here, about 300 people.
Furthermore, as you know, if you're wearing a one layer cloth mask, you're providing more protection to the people around you than you are to yourself. This study shows nothing about the propensity of people to spread the disease, only about their likelihood of getting it. If you want to protect yourself, get masks that will do that -- see some of the posts higher in this thread.
Thank you but I'll stick with the preponderance of the data from many other studies and the advice of most experts in the field and continue to wear a mask, even if I am running the risk of asphyxiation.
Yes, masks are only part of what we should be doing to protect ourselves.
