CDC Revises Coronavirus Guidance To Acknowledge That It Spreads Through Airborne Transmission (cnbc.com) 175

The Centers for Disease Control and Prevention revised its coronavirus guidance Monday, acknowledging that it can sometimes spread through airborne particles that can "linger in the air for minutes to hours" and among people who are more than six feet apart. From a report: The CDC cited published reports that demonstrated "limited, uncommon circumstances where people with COVID-19 infected others who were more than 6 feet away or shortly after the COVID-19-positive person left an area. In these instances, transmission occurred in poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise," the CDC said in a statement. "Such environments and activities may contribute to the buildup of virus-carrying particles."

The agency added that it is "much more common" for the virus to spread through larger respiratory droplets that are produced when somebody coughs, sneezes, sings, talks, or breathes. People are infected through such droplets mostly when they are in close contact with an infected person, the CDC said. "CDC's recommendations remain the same based on existing science and after a thorough technical review of the guidance," the agency said. "People can protect themselves from the virus that causes COVID-19 by staying at least 6 feet away from others, wearing a mask that covers their nose and mouth, washing their hands frequently, cleaning touched surfaces often and staying home when sick."

      And now you know why the CDC had to actually state the fucking obvious.

          Don't know why this is flamebait. A person who should be in quarantine just endangered more people to go on a pointless joyride. Now everyone in that car has to quarantine.

            There are several types of rich people. There are the old bloods. They've been rich for centuries. They are a bit aloof, but they will give money to charities and be polite to the poor and in most aspects have good behavior, because they have learned through their history that if they don't then the masquerade will crack and the vampire hunters will come out

            Then there are the nouveau riche. They just got their money. The old bloods think they are boorish, but man of the nouveau rich know that they have it good because they came from a poor or middle class background. They'll give money back to their old schools or towns. They don't intentionally want to be rude, because they still think of themselves as just one of the folks.

            Then there's the second and third generation rich. Trump is one of these, and his father was the nouveau riche. He grew up rich and has never been one of the plain people. The family however has not had money for a long enough time that they've learned to have some outward facade of humility or gentilty. So spoiled kids all grown up. Is this or is this not the stereotype that Trump fits into?

            Don't know why this is flamebait.

            Because it is clearly trying to start a political flamewar rather than discuss the topic, which is aerosol spread. The real question is why so many moderators labelled it "insightful".

            I do love the fake Biden quote, but this has nothing whatsoever to do with the topic.

        • The steroid he was given does have a low chance side-effect of mental instability, including mania. Though in this case I doubt it would have happened so quickly, so it is more likely just more of Trump's baseline mania.

          His wife doesn't really like him, his kids don't like him, he doesn't even own a pet. So to get the love he demands he needs to see his fans and absorb their adulation. Now that he's full of their vital essence he feels much stronger and is ready to go back home.

          I'd invoke hubris as an explanation, but that would suggest that the current occupant of the Oval Office had the wit or wisdom to even know what he'd been trying to hide from the American people would so ably puncture the fantasy delusions he had obviously convinced himself of. I can understand a leader so callous he doesn't care what happens to the people he claims to serve, but I can't understand a leader so fucking moronic and dense that he doesn't take it seriously even when it comes to his own safety.

          Probably the best speech of this entire campaign was given on Saturday night by a comedian playing Joe Biden. "I believe in science, and Karma. Now just imagine if science and Karma could somehow team up to send us all a message about how dangerous this virus can be. Now I'm not saying I want it to happen, but just imagine if it did."

          Quoted against the censorious trolls. A much more interesting comment than the FP, and I agree with the review of the SNL opening.

          Peripheral issue, but I keep thinking about solutions. SNL was focused on the problem of the debates, but the solution of freezing Trump with the remote control isn't realistic. But how about a kind of chess clock for the mic? Only one mic can be active at a time, and when the moderator pushes the button for one candidate, then it's only that candidate's mic for the allocated tim

          • I think the SNL metaphor was bigger than that. It's pretty clear that the writers of that skit want US voters to hit the mute on Trump. Now nothing will ever shut the man up, but there's a mad bugger tweeting insanity with the power of the Executive Branch behind him, and then there's just a mad bugger making a dime spouting bullshit on Fox and Friends. Fox has lots of room for ignorant halfwits. I think the US Government is running out of room for Trump.

          • The best moment I thought was when "Biden" pressed pause on "Trump" who froze and "Biden" says trumplessness, just for a moment. I could feel a wave of calm as "Trump" was shut up for a change.And then "Biden" presses play again and it comes rushing back. Imagine 4 years of trumplessness. Serenity.

              "Just to not hear his voice for one goddamned second..."

              Yes, it was a moment when you could almost imagine that someone of dignity and presence might actually take the blowhard's place. Biden isn't perfect, but no one who has ever occupied the White House has been perfect. Some have been slaveholders, some have been racists, some have been crooks, some have even suffered some sort of mental illness. But even the worst of them had some sense of the awesome responsibilities, trust and faith that comes with the office. Just to imagine, for a moment, that someone like even the more flawed of his predecessors might actually occupy that office next January felt like a moment of calm.

              "Let's make America not actively burn again" seems as good a promise as any.

            I like it.

            Side effect is that it would make it much more of a debate, and less of competing monologues.

          Seriously, go fuck yourself. You're just mad because its not your guy.

          If it was your guy you'd be say how because he is POTUS its critical he reassures the world he is healthy, able to run the country, and will soon be recovered or something similar - any you'd be right.

          By the way set you Trump derangement syndrome aside for a moment if you can. The president really is fairly well off or there is no way they would have done this little "stunt" if you want to call it that. If there was some real risk of him having a respiratory episode and them having to cut it short that would have look so bad its unfathomable, not to mention risking the presidents life. They would have instead release a video or something which they could just keep re-recording until he could get thru without a coughing spell what have you. They fact that they put him out there live and in person pretty much confirms he and his actual caregivers are very very confident - hate to disappoint you!

            I cannot imagine any of the other possible 2016 POTUSs; Jeb Bush, Hillary Clinton, Bernie Sanders or whoever, being as fundamentally ridiculous and monumentally awful and just plain jaw droppingly stupid as Donald Trump. Donald Trump isn't a bad President because he's a Republican. He's a bad President because he's an egomaniacal halfwit with the emotional maturity of a five year old and a grasp of the world that isn't much more advanced than his emotional age.

      Yea, sneezes and coughs, talking and even signing can *obviously* lead to airborne virus transmission though small droplets (the sort of thing that masks are good for), but this is about how long the virus can last airborne on it's own (not with water, mucus or anything else).

      They never thought it *couldn't* be spread by aerosols. The problem has always been how to give advice to a public that has the attention span of a squirrel and about the same grasp of probability.

      What people need to understand is that while aerosol transmission of COVID-19 is physically possible, it's not like the measles where you can get sick walking through a room an infected person left hours earlier. If it were, then social distancing and wearing masks other than N95 respirators would have little e

    Enough with the breathing. If someone near you is doing that, ask them politely to stop.

    • Well, to be honest, this puts them in line with Green Parties everywhere and the Green New Deal that sees human exhalations as pollutants.

  • Can we just stop all this bit flipping and just admit that the transmission risk is non-binary? We live in stupid world with people waging war over the gender spectrum but after how many months is it now still unable to comprehend something that's so obviously analogue? How long does it take to even come up with the theory that most of these things are highly variable?
  • EXCEPT when singing loudly in church choirs and at Trump rallies.
    • Screaming and spitting protesters also believe there's no risk. It must be the cleansing effect of Molotov cocktails.
