    Back to the dark side - this journalism professor who developed Politifact describes his wife's experience going to the ER as an immune-compromised covid patient: https://twitter.com/mattwaite/status...097693186?s=20

    She seems to be recovering now, but it sounds like a terrifying experience where she did not get the care she needed for lack of hospital resources.

    But various sports/entertainment approved them. And we already have many barriers in businesses (stores, PO, cubicles, etc), which is the same concept.

    The idea is to limit the travel, so something is better than nothing.
    I guess in kinda the same way as cupping your hand and putting it directly over your mouth and nose when you sneeze or cough vs. holding your hand about two inches in front of your face and sneezing or coughing. You may stop some direct ejection, but there's still tons of stuff that's gonna fly around.

    Yeah, it's similar...but most hands are smaller, there are openings, might not catch some of the projection in time, etc.

    The shield is large (or should be) and curves and hopefully catches most of anything.

    If droplets bounce off the shield and/or float off to the side and out of the area and then travel in the air, it's a different story - but that would be very difficult to pinpoint under the circumstances.

    At the end of the day, people will do whatever they want and no one truly wants to confront someone not wearing a mask (meaning it's difficult to enforce this).

    I would have never guessed shields are as effective or even more effective as masks. Never trust your intuition. From a paper that studied the effectiveness of a face shield as compared to a mask. https://www.medrxiv.org/content/10.1...090v2.full.pdf. I didn't read the paper; just glanced over the abstract and conclusions.

    "In the case of frontal exposure, for droplet diameter larger than 3 μm, the shield efficiency in blocking cough droplets was found to be comparable to that of regular surgical masks, with enhanced protection for portions of the face that the mask does not cover. Additionally, for finer particles, down to 0.3 micron diameter, a shield was found to perform even better, blocking about 10 times more fine particles than the surgical mask. When exposure from the side was considered, the performance of the shield was found to depend dramatically on its geometry. While a narrow shield allowed more droplets and aerosol to penetrate in comparison to a mask under the same configuration, a slightly wider shield significantly improved the performance. The ability of a shield worn by an infected person in order to protect others in his vicinity was also investigated. A shield, and alternatively, a surgical mask, were placed on the cough simulator, while the breathing simulator remained totally exposed. In both cases, no droplets or particles were found in the vicinity of the breathing simulator. "

    What do you think will happen if this continues for like an year more. Academics has surely taken a big hit. Online classes are nothing but a pain in the a**. Learning is very little and the universities aren't decreasing the fee structure either.

    One the major hospital chains in my area just sent out letters to all its personal informing all employees that if their spouse is Employed and is offered health care they ( the spouse of hospital employee ) will Be dropped Jan 1 2021. 17k. They said they have taken such a hit financially they can’t do it anymore. That was always one of the great perks for folks doing the difficult job.

    If that's in Texas, here come the lawsuits - From the Texas government - "The main thrust of all employment discrimination laws is to make it illegal for employers to treat employees or applicants adversely on the basis of something about themselves that they cannot change, or should not be expected to change." . Denying a benefit because you are married sounds like it fits under that definition.

    Parkview health in Indiana. Unfortunately I don’t spend as much time in Texas as I wish these days.

    Agreed. For deaf people, especially kids who depend on lip reading I can understand the need to drop the mask for those situations. Have you ever stood a couple of meters from someone wearing strong Cologne? That smell arrives at your nose courtesy of micro droplets wafted on air movement. The same when you can smell someone is cooking in the kitchen and those lovely aromas chase you. If those micro droplets can carry Cologne and cooking smells they can carry Covid virus in micro droplets. All explained by Brownian Motion. People who cannot believe that masks can help obviously have no knowledge of the physics of diffusion.
