    Better question is "Is this guy really a doctor?"

    Also given the economy will only recover if consumer confidence allows it, does it even matter if he's right. The universal wearing of masks will improve both!

    I think masks are supposed to be a fail safe for sneezing/coughing into your arm. He's right that masks don't stop the little droplets, but those are different from the larger respiratory droplets that projectile out when you cough/sneeze. CDC says those larger droplets are the primary way the virus is transmitted.

    Doesn't seem like much, but if masks make millions of people effectively cough into their arms rather than onto other people I definitely see how it could curb transmission.

    Latest Fl deaths by date through May 14th.

    I started tracking the deaths by date starting with the May 14th report. The total shown May 1-13th in that report was 402. This doesn't include 41 reported deaths for the 14th (understandable given they went to 1 day delay) but the number for May 1-13 now stands at 524, 122 higher! This could be that they are under-reporting or that they are reporting the correct number daily but don't have the DOD detail. Either way the graph is worthless as recent numbers will always show a downward trend due to being incomplete data!

    Doctors and nurses are trained and fitted to use N95 masks which do provide protection from viruses. During flu season when you go to a doctor's office they usually give you a surgical mask to wear which keeps you from spewing your virus filled spit all over the place. Masks were originally advised against to prevent people from hoarding N95s away from healthcare professionals who actually know how to use them and opted instead for physical distancing which ideally should be enough to keep droplets from going from one person to another. In practice it didn't work. Health agencies then said everyone should wear a cloth covering in addition to physical distancing to prevent carriers from infecting healthy people. This approach only works if everyone does it.

    Fleming, that "doctor" shows he should stick to surgery, not epidemiology. This also shows the danger of any individual trying to increase the weight of his or her statements by using pedigree. Nobody, whether they have lots of PhDs or never graduated high school should be given a voice that does not reflect reality. Bias affects us all and just because we want to believe something, doesn't make it true. Anyone who thinks with bias first and analytics second will be wrong more often. Reducing bias isn't about being PC, it is about not letting your analytics be compromised.

    It is not the virus a mask is stopping, it is the water vapor droplets that the virus rides on that are 10-15 microns in size, far bigger than the spacing in a bandana or an N95 mask, that is blocked by the mask. If Covid19 was a pure airborn (corrected the spelling thanks to I think Gray on an earlier post) virus, it would be able to survive on hard surfaces for a lot longer period of time than studies show it can.

    So, wearing a mask stops water droplets from leaving your mouth and from coming to you from another mouth. The N95 means it stops 95% of them, with a bandana being less. It is only when two people are wearing a mask/banadana that the spread is stopped more effectively because outbound and inbound water droplets are reduced by 95%. The other 5% is escaping around the imperfect connection with one's face as droplets can escape out the sides, especially when we lower it to talk.

    I"m going to beat my drum again, which is wearing masks, washing hands and social distancing is important just as opening the economy is too. In the end, it is about protecting America and not taking an either/or one-sided approach to things.

    If both are wearing N95 the chance of transmission is 5% out times 5% in which equates to 0.25% or prevents transmission 399 of 400 times than the same event without masks.

    This is a good article that brings up some of the questions raised here:

  • GrayDawgGrayDawg Posts: 1,907 ✭✭✭✭✭ Graduate

    That may be the most condescending article I've ever read. New science didn't change the recommendation not to wear a mask. People calling bullsh*t about their ineffectiveness when they saw actual doctors wearing them while the CDC said they don't really work is what got the policy changed.

    People aren't confused about it now. They are cynical. They don't like being treated like half-wits.

    I thought the purpose of a lockdown was to flatten the curve and avoid overwhelming our hospitals. You're telling me we need a lockdown until there is a cure? Good luck with that plan.

    I understand very clearly that certain parallels can be drawn between cities to fit an opinion. You could find parallels to fit just about any opinion. I fully grasp your line of thinking. I just don't fully agree with it. I may never fully agree with it.

    Doctors and nurses wear different types of masks than the general public because they wear masks for a different reason. They are constantly interacting with infected people so they need N95 masks to reduce their chance of getting infected. They are trained in how to wear them and have to get fitted to make sure the mask forms a proper seal around the face. The public was advised to wear cloth masks to prevent water droplets from spreading which would prevent asymptomatic and mild cases from infecting others. A healthy individual wearing a mask does not have much protection from contracting COVID-19 if they were to be exposed to an infected individual not wearing a mask. Masks only provide protection if everyone wears them.

    Flattening the curve and slowing the spread are the same thing!

    I am not saying the lockdown should remain in effect until a cure is developed, A prompt lockdown enables each country/state to get the process and people in place to test, trace and isolate and can be released when that is achieved as long as people follow social distancing rule including a mask. A lockdown is imposed to enable the government to get a handle on the problem (scope and size). They isolate everybody because they can't identify who needs to be individually isolated.
