Tons of people without symptoms get tested now

The fact is that the purpose of the mask is as much about demonstrating conformity to requirements than anything else.

Another study looked at coronavirus deaths across 198 countries and found that those with cultural norms or government policies favoring mask-wearing had lower death rates.

Two compelling case reports also suggest that masks can prevent transmission in high-risk scenarios, said Chin-Hong and Rutherford. In one case, a man flew from China to Toronto and subsequently tested positive for COVID-19. He had a dry cough and wore a mask on the flight, and all 25 people closest to him on the flight tested negative for COVID-19. In another case, in late May, two hair stylists in Missouri had close contact with 140 clients while sick with COVID-19. Everyone wore a mask and none of the clients tested positive.

In one simulation, researchers predicted that 80 percent of the population wearing masks would do more to reduce COVID-19 spread than a strict lockdown.

The latest forecast from the Institute of Health Metrics and Evaluation suggests that 33,000 deaths could be avoided by October 1 if 95 percent of people wore masks in public.

Even if you live in a community where few people wear masks, you would still reduce your own chances of catching the virus by wearing one, said Chin-Hong and Rutherford.

“The concept is risk reduction rather than absolute prevention,” said Chin-Hong. “You don’t throw up your hands if you think a mask is not 100 percent effective. That’s silly. Nobody’s taking a cholesterol medicine because they’re going to prevent a heart attack 100 percent of the time, but you’re reducing your risk substantially.”

We know that wearing a mask outside health care facilities offers little, if any, protection from infection. Public health authorities define a significant exposure to Covid-19 as face-to-face contact within 6 feet with a patient with symptomatic Covid-19 that is sustained for at least a few minutes (and some say more than 10 minutes or even 30 minutes). The chance of catching Covid-19 from a passing interaction in a public space is therefore minimal. In many cases, the desire for widespread masking is a reflexive reaction to anxiety over the pandemic.

>> Use of Masks and Personal Protective Equipment

Masks and other personal protective equipment (PPE)are essential for controlling transmission of influenza in hospitals. For people who work in hospitals, current CDC guidelines for influenza infection control recommend droplet precautions, including the use of surgical masks.But HHS planning guidelines also rightly acknowledge that the uncertainties regarding the potential of virus transmission at the start of a new pandemic would recommend that airborne precautions be used in hospitals—that is, N95masks (already in short supply)7or powered air purifying respirators (PAPRs).10Patients would be advised to wear surgical masks to diminish the number of infectious respiratory particles being dispersed into the air, thereby diminishing the likelihood of further spread.55

In Asia during the SARS period, many people in the affected communities wore surgical masks when in public. But studies have shown that the ordinary surgical mask does little to prevent inhalation of small droplets bearing influenza virus.56 The pores in the mask become blocked by moisture from breathing, and the air stream simply diverts around the mask. There are few data avail-able to support the efficacy of N95 or surgical masks out-side a healthcare setting. N95 masks need to be fit-tested to be efficacious and are uncomfortable to wear for more than an hour or two.55,57 More important, the supplies of such masks are too limited to even ensure that hospitals will have necessary reserves.58 <<

Interestingly, the authors of that paper, who argue against lockdowns, masks, etc, are now total virusbadmos. Wonder what changed?

The other issue is that cases are down BIGLY in most lib cities where mask compliance is high, but skyrocketing in Florida, AZ, TX, etc., where mask compliance is low because MUH FREEDOMS.

Everyone takes them off when they eat because you obviously can't eat through a mask.

Flame. It doesn't help as much as an N95, but it still works about half as well.

EDIT: some retard below responded with an earlier, shittier paper that has been retracted for being statistically underpowered, something mentioned at the top of the article he linked, LOL.

The difference between viruses could have something to do with where in the respiratory tract these infectious invaders make their homes, said Cowling, who is also co-director of the WHO Collaborating Center for Infectious Disease Epidemiology and Control. For example, a virus that reproduces deep in the lungs might need to travel in smaller particles to make it all the way out into the world, while one that reproduces mostly in the nose and throat may be more easily mobilized in bigger droplets.

The results from influenza and seasonal coronaviruses suggest that surgical masks can help keep people with COVID-19 from spreading the virus, Cowling said. SARS-CoV-2 probably behaves similarly to the viruses he and his team studied, he said, and the fact that people can spread the virus before they experience symptoms is an argument for recommending masks for everyone.

But experts are still mixed on the potential usefulness of non-N95 masks.

"To me, it's not harmful to wear these masks, but it doesn't look from this study like there is a whole lot of benefit," Jones said. The sample size for seasonal coronavirus was small, she said, and there was a large amount of non-mask-related variation in how much virus people emitted, particularly given that the majority of samples without masks didn't have detectable coronavirus.

One thing everyone does agree on is that, whatever containment provided by non-fitted masks do provide, homemade fabric masks are the least effective. The recommendations that everyone wear masks are because "any kind of impediment is better than nothing," Chu said. But fabric masks are not expected to be as protective as surgical masks, she said. That's why public health officials are warning people to remain at least 6 feet apart from one another, even if they are wearing masks. In other words, homemade masks are likely to be just a small piece of the puzzle for controlling the COVID-19 pandemic.

"There's been enough research done to be able to confidently say that masks wouldn't be able to stop the spread of infection, that they would only have a small effect on transmission," Cowling said. "We shouldn't be relying on masks to help us go back to normal."

I doubt masks mitigate more than 10% at best

it's mostly a placebo

I leave an N95 in my car and throw it on when I go into a store. It's no more difficult than a cloth mask.

You are supposed to throw them out mostly because they become contaminated -- ie, if you're a doctor in a hospital, there will be COVID germs all over it. If you're just wearing it into the supermarket for 30 minutes, you don't need to throw it out as often.

(http://www.autoadmit.com/thread.php?thread_id=4580619&forum_id=2#40580951)

is it basically that you have to have prolonged direct physical exposure to someone exhaling virus within 3 feet of you?

Lol kill yourself queer

And nursing homes of course

It's all for show.
