Simply putting your hand over your nose and mouth when you sneeze
or cough is worse even that wearing a surgical mask—as far as preventing
the viral particles being expelled into the surrounding air. And if you're an
asymptomatic carrier of the virus, it'll be on your hands, and easily transferred
to taps or doorknobs or someone else's skin. The most effective prevention
is a fitted N95 mask.
Since I can't deposit any internet sites yet, you can type in,
"
Mask works best? We filmed people coughing and sneezing to find out".
Remember, the particles that you see coming out are the visible droplets mixed with dust particles, and other airborne pollutants. We can't see the viruses. They are just too small to be seen. But we can measure the viral load. And estimate the amounts of viruses being expectorated. Other experiments have collected the expectorants, and counted the number viruses. Remember, it only takes about 100 viruses to infect a human. And, NO MASK CLAIMS TO BE 100% EFFECTIVE.
Regarding asymptomatic carriers, I disagree. Although the evidence DOES suggest, that PRE-SYMPTOMATIC carriers(around 2 days before the onset of symptoms) can shed this virus. Which can become airborne, or can be transferred to different surfaces.
But there is no verifiable, or reproducible evidence to suggest that ASYMPTOMATIC carriers(no symptoms at all) can spread this virus. I have only seen assumptions, speculations, opinions, and arguments from ignorance. Plus, the claim is just too counterintuitive for me.
But if you understand the life-cycle of a virus, then you would know, that all viruses need their host's immune response system, to spread itself to a new host. Viruses don't just jump onto a host that happens to be within 6 feet of them.
Therefore, no immune response, no symptoms, no transmission of the virus. I also agree that since nature is not perfect, there may be a few exceptions to this. But these exceptions are NOT the rule.

I've noticed close-contact healthcare workers wearing these full face shields:
Some are. But most aren't. The professionals working in the healthcare industry, are more than twice as likely of becoming infected. I'm afraid that the earliest stats I could find were in Feb of 2021. At that time, there were 90/100K healthcare workers infected(23.4K). To 34/100K of the general population infected(8.8K). That's over 2 times the risk of infections.

In the last 20 years, the measles vaccine is estimated to have averted more
than 30 million deaths globally. Estimated deaths from measles dropped from
around 1,070,000 globally in 2000 to 60,700 in 2020.
Since March 2020, 6,588,591 people have died from COVID, which means that
it kills far more people globally than measles.
I think you have a misunderstanding of both, the "Infection Mortality Rate"(which is falling), and the "Case Mortality Rate"(also decreasing). Neither depends exclusively, on the total number of deaths with/from the disease. Their rates are determined by the number of deaths by a disease divided by the number of confirmed cases of the disease.
Lets say you have a global disease where only 100 people are infected. But, 100 people die from the disease. This would be a disease with a mortality rate of 100%. And, a survivability rate of 0%. Now, compare this to a global disease(Covid-19) that has infected 629M people, and 6.58M have died with/from the disease. This is a disease with a mortality rate of 1%(the measles is 1-3%). And, a survivability rate of 99%.
As you can see, the number of deaths is NOT the relevant factor alone. I think given the choice of being infected with Rabies(100% fatal), Ebola(90% fatal), or Cov-19(1% fatal), my choice would be a no-brainer. The mortality rate of a disease, is the RATE in which a disease kills people. NOT, the total number of people the disease kills.
