The protests and marches have been going on for a month and it doesn’t look like they’ve spread the disease. Many marching wore masks. Coincidence?
Lockdowns work.

WHO Chief On COVID-19 Pandemic: 'The Worst Is Yet To Come'
Speaking at a briefing in Geneva, Tedros Adhanom Ghebreyesus says: "We all want this to be over. We all want to get on with our lives. But the hard reality is this is not even close to being over."

I haven't looked too closely, but I'm sure there are scientists who are watching that particular situation with some interest and will come along with data in the not too distant future. Right now it's an educated guess based on the best available evidence, my guess too btw.

Increasingly evidence is pointing to indoor airborne spread as the primary culpert and asymptomatic people don't spread as much as presymptomatic people etc. Mask wearing and hand hygiene are the way to go with as much business as possible conducted in the outdoors, preferably in the sun if possible. No bars, in door dining, sports events or other mass gatherings, that's just stupid, haircuts yes, with precautions and testing the staff at least twice a week minimum. That spartan cube testing gizmo should be deployed by now in Canada with numbers increasing daily and it would be perfect for such tasks.
I'd like an update on this thing, Ontario ordered a million of them alone.
The trouble with COVID-19 swabs: The case of Ottawa's Spartan Bioscience
On May 1, Lem learned that the National Microbiology Laboratory was not impressed with the "efficacy" of the swabs Spartan used to collect samples of SARS-CoV-2 — the virus that causes COVID-19.

The best DIY face mask material and fit? Quilting cotton beats bandana, new study suggests | CNN
The most effective non-medical masks for Covid-19 are homemade stitched masks. Researchers experimented with different choices in material and design to determine how well face masks block droplets as they exit the mouth.
The best DIY face mask material and fit? Quilting cotton beats bandana, new study suggests
(CNN)Wearing face masks and coverings is recommended, or in some places mandatory, in public spaces to help stop the spread of Covid-19.
But what kind of DIY face covering offers the best protection?
Researchers at Florida Atlantic University have experimented with different materials and styles of non-medical masks and found that a well-fitted stitched mask made from two layers of quilting fabric was the most effective in stopping the spread of droplets from emulated coughs and sneezes.
They also compared a loosely folded homemade face mask, such as one you could make with a handkerchief or T-shirt, a bandana-style face covering and a cone-style non-sterile commercial mask that is usually available at pharmacies.
The researchers said they chose to test these styles of face covering because they are readily available to the general public and do not draw away from the supply of medical-grade masks and respirators for health care workers.
"While there are a few prior studies on the effectiveness of medical-grade equipment, we don't have a lot of information about the cloth-based coverings that are most accessible to us at present," said Siddhartha Verma, an assistant professor at the department of ocean and mechanical engineering at Florida Atlantic University and author of the study.
With the stitched cotton mask, droplets traveled 2.5 inches.
"Our hope is that the visualizations presented in the paper help convey the rationale behind the recommendations for social distancing and using face masks."
The study published in the journal Physics of Fluids on Tuesday.
The World Health Organization says governments should encourage people to wear non-medical, fabric masks, especially in settings where physical distancing of at least 1 meter is not possible -- such as on public transport, in shops or in other confined or crowded environments.
In the US, the Centers for Disease Control and Prevention recommends cloth face coverings to protect others in places where social distancing can't be maintained.
Emulating coughs and sneezes
In the experiment, a mannequin's head was padded inside to emulate a person's nasal passages and mounted at a height of 5' 8" to approximate the height of an adult male. The researchers "delivered" the sneeze or cough using a manual pump and a smoke generator.
With a folded cotton handkerchief, droplets traveled 1 foot, 3 inches
They then used a laser to detect droplets as they were coughed and sneezed out of the mannequin's head and mapped the paths of droplets and examined how different designs and materials alter that path.
The main challenge for the researchers was how to faithfully simulate a cough and sneeze.
"The setup we have used (is) a simplified cough, which, in reality, is complex and dynamic," Verma said in a statement.
Do masks mask our emotions? Not necessarily, says one expert
They found that droplets from a simulated uncovered cough were able to travel more than 8 feet; with a bandana they traveled 3 feet, with a folded cotton handkerchief, they traveled 1 foot, 3 inches; and with the cone-style mask, droplets traveled about 8 inches. With the stitched-quilting fabric mask, they traveled 2.5 inches.
"We found that although the unobstructed turbulent jets were observed to travel up to 12 feet, a large majority of the ejected droplets fell to the ground by this point," said Manhar Dhanak, a professor at Florida Atlantic University's department of ocean and mechanical engineering and co-author of the study.
"Importantly, both the number and concentration of the droplets will decrease with increasing distance, which is the fundamental rationale behind social-distancing."
With the cone-style mask, droplets traveled about 8 inches.
A higher thread count by itself was not more effective, the researchers said. In their experiment, the bandana had the highest count and was the least effective.
They said their experiment could help health care professionals, medical researchers and manufacturers assess the effectiveness of face masks.
The WHO recommends cleaning your hands before touching a mask, making sure it's not too loose and covers the mouth and nose. It says you should store it in a clean bag if you plan to reuse it and wash it every day with soap and hot water.

Ultimately, most people have very little control over their most precious properties, their own body and their own home and/or homestead.
My persistent theme is that those things, at a minimum should be under the control of the owner.
I agree, one may or may not have absolute control over their own property.

If you or I do not have the right to force another person to wear a mask, how could we possibly delegate that nonexistent right to an overlord(s) to bark out a mandatory mask edict ?
Car accidents kill about 40,000 people per year. Should cars be eliminated, "if we can save just one life" ?

But, in any car accident resulting in a death, a car is involved.
I agree car accidents don't spread asymptomatically* , but your chances of dying in a car accident might even be greater than your chances of dying from a hyped up virus that is insignificant to most people who aren't elderly.
My analogy was meant not on the transmission method, it was meant as a comparative.
Also, I see you didn't address my question on who has any right to delegate a nonexistent right. Not surprised, nobody ever goes there.
*although car driving behaviors and road rage can increase with proximity to other bad drivers, especially if the other driver is/isn't wearing a mask lol

Do you actually believe that nonsense about 'insignificant to most people who aren't elderly'?

This virus is very real and very dangerous. Trolling is fun and all, but stay safe and don't spread the virus nor the anti-vaxxer bullshit that has lead to measles outbreaks where it was virtually eliminated.

I didn't address your question because I do not volunteer or willfully consent to involve myself in conversations where the skulduggery of semantic word play is consistently utilized in an effort to lend relevance to outdated and unrealistic socioeconomic philosophy.
Good luck forming your utopia...

That's great. Are you saying you want to play a game of government caused deaths versus government lives saved ?
I'll go first. Democide. I win.
