One cannot extrapolate a gaiter study and make assumptions about masks in general. Many people do not understand the parameters of legitimate scientific studies and attempt to draw unfounded conclusions. Not only is that a major error it can be seriously dangerous.

This is a peer review study that shows gaiters don't even work but are in fact, according to this peer review study more dangerous to wear.
I choose to believe peer review studies like this one.
Instead of reading what a Wash Post reporter wrote about this study let’s go read what the Duke researchers published.
Low-cost measurement of face mask effica........iltering expelled droplets during speech
This is a good quote showing the effectiveness of some cloth masks and a surgical mask at blocking emitted droplets from speech. In the study (unlike the video) the performance of each mask was compared to not wearing a mask. Unlike the video where the vapor was blown out; the study measured droplets emitted during speech.
Quote:For the control trial (green curve), the five distinct peaks correspond to the five repetitions of the operator speaking. In the case of speaking through a mask, there is a physical barrier, which results in a reduction of transmitted droplets and a significant delay between speaking and detecting particles. In effect, the mask acts as a temporal low-pass filter, smoothens the droplet rate over time, and reduces the overall transmission. For the bandana (red curve), the droplet rate is merely reduced by a factor of 2, and the repetitions of the speech are still noticeable. The effect of the cotton mask (orange curve) is much stronger. The speech pattern is no longer recognizable, and most of the droplets, compared to the control trial, are removed. The curve for the surgical mask is not visible on this scale.
This is a link to figures of their data comparing the performance of the masks tested relative to no mask.
Data Figure; there is a picture in the linked article showing all the masks tested.

I've read reports of the mutations of the SARS-CoV-2 virus. Most reports have indicated that the mutations to date won't have much effect on how the current vaccines in development may work. That's reassuring if it turns out to be true.
BTW, viral mutations are not unusual. It's interesting that they can find the RNA sequence and then use these mutations to track the viral spread and form a pretty good idea where outbreaks originated and where they spread.

I'm not convinced of that, while not widespread there are documented cases of a recovered (and presumably then immune) patient catching CoVid-19 for a second time because the second infection was a sufficiently different mutation to slide by the body's defenses.
Even the experts can't agree on how much, or if, this will be a game-changer.
Clicky, clicky.

For what it is worth, the mutation rates for influenza, measles, and mumps are all about the same. The mutation rate clearly does not correlate with how long a vaccine will be effective for the circulating virus strain. For measles and mumps the vaccines (or infection) provide lifetime immunity. For the influenza viruses, the immunity is much shorter because the mutations were in functionally relative locations.

I can only speak for myself with regards to this answer.
I was unfortunate enough to suffer two episodes of influenza last winter. They occurred two and a half months apart. I telephoned the CDC after the 2nd episode and continued by email.
I described my symptoms and the doctor suspected I had contracted both strains the H1N1 and H3N2. I was bedridden for 12 days in late Feb. I had received the potent senior's vaccine the prior October.
I would like to know why, at the end of both episodes I had fallen I'll again for a day. This has happened prior with the flu. Includes fever and muscular aches and pains. It is not the product of superinfection because it only lasts a day or so. The episodes are not subtle.
I would also like to know the composition of the 2020-2021 influenza vaccines since for me the prior year's inoculation was a total failure for me.

Chief science officer for Pfizer says "second wave" Faked........
Very interesting what a former Pfizer Chief Science officer has to say about fake and false data. I agree with the Chief Science officer that it looks like sloppy science to me.

Please provide peer reviewed published reports indicating the false positive rates for the RT-PCR tests. In other words fact check what someone says even when it supports your preconceived bias (which is what science does).
This is no different than accepting vape particles are much bigger than droplets that carry viruses (which is incorrect) since it supports what you want to be the truth.

Again, you choose one person's perspective and choose to ignore every one else.
This was stated in his argument:
Quote:In the data for UK, Sweden, the US, and the world, it can be seen that in all cases, deaths were on the rise in March through mid or late April, then began tapering off in a smooth slope which flattened around the end of June and continues to today. The case rates however, based on testing, rise and swing upwards and downwards wildly.
I can see a flaw immediately. He assumes the decrease in death rate is due to decrease in actual cases. Therefore, since there is a decrease in death rate the increase in cases must be due to "false positives."
In actuality, the new cases are hitting age groups where death is not as common an outcome AND our medical professionals have learned a tremendous amount about this disease and how to treat it. They have tools and treatment protocols not available or utilized in March, April and May and have a much better chance at saving those infected. Possible reason for decreased death rate despite rising cases???
