The statistics from Sweden prove one thing...it's the elderly and sickly that need to stay isolated...out of all the Covid deaths in Sweden only a couple of dozen were under the age of 40...
I don't disagree that the elderly are most vulnerable. That's the same everywhere. I disagree with having 10 times as many die as need to
BTW telling folks that their thinking or opinions are flawed because they don't understand something or some process is a gross miscalculation on your part and it's a fundamental mistake in getting someone to look at something differently...
Again, I don't necessarily disagree. My approach could be softer. Fair enough.
However, when individuals continually spew incorrect information, make claims that can't be backed up, and then disparage scientific experts that are trying to save lives. Well, I have my limits.
AND FYI...unless you are talking about something that (any science) is 100% finite and complete (nothing else left to learn, which is nothing BTW)...especially with a science that has just recently started getting closer examination like human moisture droplet dispersal...there really are no facts...just interpretations of the latest findings...A lot of research right now is looking at the COVID virus as solid particles and not in suspension of moisture...
This is where you are incorrect. There is a wealth of research that has been performed on human droplet emissions as a vector for transmission of infectious diseases. The seminal paper by H.G. Wells, which has unfortunately been highly misrepresented by the media, leading to misconceptions about the "6 foot rule" was published in 1937.
If you are interested in more recent work, look up Linsey Marr at Virginia Tech or Lydia Bourouiba at MIT. They have been heavily involved in bioaerosol research long before COVID-19 came along.
So, actually, the science is not all new by a long stretch. This is precisely why the aerosol science community is so exasperrated. It's ridiculous that we are debating about the physics of droplet transport when it has been understood for so long.
There are admittedly nuances with it being a new virus such as where it is shed, infectivity, and viability as an aersol. Certainly the emergence of asymptomatic/presymptomatic spread is something that hasn't been widely observed before (only limited instances in SARS-CoV-1). There are many of avenues of research ongoing to answer additional questions.
However, the issue of whether masks are effective (which is what started this thread) is well understood and proven.
