COVID-19: Without masks, two metres distancing is not enough:

To prevent the spread of COVID-19 indoors, the two metres physical distancing guideline is not enough without masks, according to researchers from Quebec, Illinois, and Texas. However, wearing a mask indoors can reduce the contamination range of airborne particles by about 67 percent.

“Mask mandates and good ventilation are critically important to curb the spread of more contagious strains of COVID-19, especially during the flu season and winter months as more people socialize indoors,” says Saad Akhtar, a former doctoral student under the supervision of Professor Agus Sasmito at McGill University.

While most public health guidelines recommend physical distancing of two metres for people from different households, the researchers say distancing alone is not enough to prevent the spread of COVID-19. In a study published in Building and Environment, the researchers found that when people are unmasked, more than 70 percent of airborne particles pass the two metres threshold within the 30 seconds. By contrast, less than 1 percent of particles cross the two-metre mark if masks are worn.

Coughing is one of the main sources of spread of airborne viruses from symptomatic individuals.

    I see the "facts" you linked to. And your bible quotation.

    Revelation 18:23 = "for by thy sorceries were all nations deceived.” & GREEK for SORCERY/WITCHCRAFT = Pharmakeia (pharmaceuticals)...

    I would refer you to an answer I gave here. [soylentnews.org]

    Here is another thing I would point out about conditions in the present day when this post was written:
    (referring to Rev 13)
    * there is currently no beast
    * there is currently no false prophet
    * there is currently no image of the beast created by the false prophet
    * there is currently no global mandate to bow down to the non yet existing image
    * there is no global mandate to take a mark

    I also pointed out that I know of missionaries who have been vaccinated in order that they can travel safely and follow their calling.

    I have heard the argument about the greek word translated to English as "sorceries" is Pharmakeia and therefore MUST SOMEHOW have some connection with pharmaceuticals and vaccines. Maybe all vaccines and all drugs of any kind whatsoever. So definitely do not take any DayQuill! Oh my! I find such an argument unconvincing.

    I know the text. I read and reread it. I watch for the rise of antichrist. But I don't see it yet. This vaccine is not the droids you are looking for. Move along.

    John the revelator wrote from patmos (isle off Greece iirc) & used GREEK originally, so don't even TRY "outsmart me" on scripture (& your bs doesn't apply to MY post period though I could tear that up easily too) OR greek since any FOOL can see the roots of PHARMA (& all its derivates) roots of "pharmakeia". Same virtue knowing LATIN has for roots for meanings of terms.

    I also see you AVOID this to NO END since it's facts you can't get the best of too & instead you all 'downmod hid" it, lol https://soylentnews.org/comments.pl?noupdate=1&sid=45332&page=1&cid=1184773#commentwrap [soylentnews.org]

    * Satan uses scripture too & RELATIVE TRUTH (fails vs. facts, merely a point of view SATAN himself used to deceive EVE the dumb bitch) - it fails with your "interpretations", lol - the province of losers vs. fact & common-sense, everytime.

    APK

    P.S.=> Everyone knows (especially admins on this site who state it here) Soylentnews has become sockpuppet fake account heaven for the real trolls on this site https://soylentnews.org/article.pl?sid=21/08/19/0211237 [soylentnews.org] that upmod themself (under many fake accounts) and downmod hide facts you can't overcome per the 1st link posted above.

      John the revelator wrote from patmos (isle off Greece iirc) & used GREEK originally . . . etc

      Yes, I've had six decades to learn all this and more.

      so don't even TRY "outsmart me" on scripture

      I gave a few quotations, and my own views of it, and stated it is just my opinion. (But those views are not my opinion alone.)

      I would never try to outsmart someone as obviously clever as yourself.

      If you think this particular vaccine is the mark of the beast, I will not attempt any further to convince you otherwise. There is no point.

        As he said on Satan quoting scripture too using "relative truth' (fails vs. facts, just as you all seem to do here avoiding all of his points and downmod hiding it) https://soylentnews.org/comments.pl?noupdate=1&sid=45332&page=1&cid=1184773#commentwrap [soylentnews.org] you admit you fail then by using your 'interpretations' where you admit greek is the root language used for pharmakeia now, correctly, and sense says like Latin, you determine meanings of words by their native/root tongue and go from there. You also avoid his question on why you'd take a shot that is known to fuck you up. Why's that? Tough to deny it based on facts in the link above, isn't it? I feel sorry for you man. I really do. you got suckered. All they have to do is make people be afraid to turn them into SHEEPLE! Don't ever try outsmart APK. He's made a career of making others "EAT THEIR WORDS" & literally has destroyed his opponents using that very phrase most every time he does. Slashdotters have seen him do it 1,000's of times.

          why you'd take a shot that is known to fuck you up

          I got vaccinated. It didn't fuck me up at all. Am I doing it wrong?

    Odd you avoid a question he asked of you here in you now deflecting from it https://soylentnews.org/comments.pl?noupdate=1&sid=45332&page=1&cid=1184834#commentwrap [soylentnews.org]
