Why Wearing A Mask Matters: Coronavirus Transmission Explained | All In | MSNBC

94 comments

  1. Why is this news? In Asia, people wear masks whenever they get the cold to reduce the risk of infecting others. This has been in use since SARS almost 20 years ago.

    1. Wrong. Mask wearing in Asia is a norm because of the toxic air they have. They wear it so they dont get sick from it. The whole infectious disease came afterwards.

    2. It doesn’t actually reduce the risk though. If we use common sense and stop being zombies, one would understand how germs work.

      Think about the entire process of putting your mask on, taking it off, etc. do you think that mask has no germs on it?

      Fact of the matter is, if you don’t want to infect someone, stay away from them. Covering your mouth and nose won’t stop germs that are more than likely already on your clothing.

    1. gamer kid Not all of us are stupid. Its only the people who protest the lockdown, they’re the stupid ones

    2. 😂😂😂😂😂Americans will be even more stupid after drinking clorox and Windex on the rocks

    1. They found a old volcano on the moon you could try that, but my guess is that is where the ET from the UFO lives.

  2. How come we all have to wear a mask but the media and governors and government don’t have too. I call bulshit 🤪

    1. @cheeze 11 did you read the agreement on irs.gov they expect us to give up or 4 adminment and possibly be constantly monitored to receive payment. It’s one of many overthrows of government that they are not arrested for. They basically get away with what ever they want as the president bragged about.

    2. @Jacob Clark my husband is a veteran and so aren’t alot of my friends. They don’t wear a mask because they KNOW there is something more to this than you think. I would ask you to do some research. And don’t start with the news. God bless you 🙏

    3. @Kelly Farver I started my research over 20 years ago ,    right now our death toll is a Vietnam and This is the kind of attitude that will make it a WW2 in the number of deaths , when my grandfather was in WW1 they had to do things like pea on their masks to survive the atact. can’t we show are veterans so respect in their time of need by helping to protect their lives now by simply putting are masks on ? Or is this too much of an inconvenience to ask for? The whole world but America got it wrong ?

    4. @Jacob Clark Sr. With all due respect I will not be wearing a mask. I don’t need the government to tell me if I’m sick stay home. That is plan common sense. So why all of a sudden do we need to be told what to do.??? My faith is in God and not no mask. Good day sr. God bless 🙏

    1. @Mochix i’ve seen more people touching their face BECAUSE of the mask, adjusting it and whatnot, than anything else.

    2. Those who want to pretend that this virus aren’t that bad let them! I refuse to spend my precious time trying to convince them otherwise! I remember saying months ago that a lot more people will have to die from this virus before we take it seriously! And unfortunately we’re not there yet!

  3. A common sense that Asian countries knew 3 months ago and US need a scientist to do the experiment. Remember CDC’s guideline “no need to wear mask unless you are sick”? That’s absurd.

    1. @DARLING Blame yourselves. At the very beginning, the US should have tested those ppl who were in contact with those already known infected. But you were lazy and complacent. Many non western countries already know the importance of contact tracing to contain the epidemic. That’s not China fault if stupid ppl voted for a stupid president.

    2. Why is it absurd? This test proves mask dont do anything. instead of going forward its all stuck in 1 spot for the next person to walk into. If anything it proves you need to cover your month when you cough.

    3. @chly coh China’s actions affect more than just the United States. Their government lied. Still is as I put this message up. Still telling lies. The United States will make the right choice and dethrone Emperor Trump. His lunatic ravings are a national embarrassment no doubt. But something tells me that regardless of who was elected the outcome would have been the same. Perhaps less embarrassing with Clinton in office. But then the average American voter wouldn’t have learned a valuable lesson: career entertainers do not make good politicians!

    4. Lmao, so you think Asians just go around wearing masks all the time? Asians only wear masks when THEY are sick, not the other way around.

      These idiots are telling us to wear masks 24/7 even after the lockdown ends.

    1. @Maria Luisa Cardenas He should stop eating baked beans ,cabbage, broccoli ,asparagus brussel sprouts 😂😂😂

    1. ​@ShockMe1994 Shouldn’t you be mad that the government and media lied to you about it and risked your health?

    2. They are reporting the new info released by sme’s. Okay, 1. there were not enough masks for health workers – can’t have 350 mill ppl buying what little there is, 2. They have been doing experiments to see the spread vectors 3. China, Korea, Italy did not have enough clinical data on spread….focus was surfaces, 4. If they said where a mask, would people? Not until the disaster lay before them. Lots aren’t wearing one now. 5. Things are changing, much is being learned. Remain vigilant and open minded. It will serve you well.

    3. @ShockMe1994 Running out of what? They were trying to shame people that already had masks. They don’t understand how capitalism works.

    4. That’s because it’s been a learning process, I guess only “dizzy hole” knew the characteristics of this virus before anybody else,

    1. @Mark Ramsey fully agree. They lied to us from the beginning by telling us it is useless, even they knew it was useful because all the healthcare workers had it on. Now we generally public ended up no mask at all to buy from. We have all been lied to!

    2. They change the narrative every five minutes see it is a airborne virus that is why the mask story is now first the democrats lied not to instill panic about a airborne virus in March when the Corona arrived in United States airspace on March 15 now the Democratic liars are saying to wear mask they should have ordered that on March 15 when the United States military detected the first signs of the airborne Corona virus on the east coast of the United States the military satellites picked up the first traces of the Corona moving across the Atlantic ocean on March I that is when the mask initiative should have been ordered !

    3. @Jon Jonas What does “democrats” have to do with anything? Viruses don’t care what your politics are. Why is it democrats job to do anything? Only the president has the authority to invoke the defense production act. Why did the president cut finding for the CDC two years ago – specifically the parts that do foreign monitoring? Why did he dismantle the pandemic response team? Why did he do a 2 trillion dollar tax cut for his rich buddies and now states don’t have money for supplies? The democrats had no control over any of that.

      And the narrative isn’t changing every five minutes. It has changed in two months. During that 60 day period, the number of confirmed cases went from about 15 to over 500,000. The tactics needed to fight a disease are different when the numbers are that different. When you’ve got 15 cases, the best way to fight the disease is to prevent others from getting it in the first place. But when you’ve got 500,000 cases, the goal changes to stopping people from giving to to others. That’s not a conspiracy or a flip flop. The circumstances have changed, so the tactics to deal with it have to change. Simple as that.

      And masks and tests should have been ordered – not in March – but in JANUARY when we first knew the disease was in the US. Democrats don’t have the authority to order masks. Again, the only person with the authority to invoke the Defense Production Act is Donald Trump, and last I checked he was republican.
      Trump delayed because he thought it would make him look bad to have an outbreak on his watch and by the time he took it seriously, it was too late. Now we have the highest number of cases in the world and 1 out of 3 deaths from the virus are in the USA. If you’d stop making everything political and listen to a pandemic expert, you’d understand.

    4. @Jon Jonas Why ten years? Why not ever for the rest of your life? What is it about the next ten years that will change your mind on mask usage?

    1. @Shirley Hannel Government: Don’t look at the sun during an eclipse, it is dangerous and you could go blind.

      Trumpanzee: DON’T TELL ME WHAT TO DO!!! TYRANT!!!! MY FREEDUMB!!!!! *looks at sun during eclipse*

  4. chinese researchers a few months ago: “the virus can spread through saliva and aerosol”
    US: “dont believe anything they say!!!”
    US: “we are still figuring out how the virus spread”

    1. @sidekicKs Just stay home and wear your mask by all means if that’s how you feel safe. The world is a germy place, you wouldn’t want to challenge your immune system.

    2. R. Káva still your slippery slope didnt change at all. I dont want to waste my energy anymore if wearing masks means smothering immune system and not washing hands to you.

    3. Sadly, it’s the other way around. The US believed China’s lies about the numbers, and ultimately ended up slightly underestimating things.

    4. Ghost_Troupe cuz CN initiated lock down of cuz the numbers are less serious than those countries who claimed its a “hoax” and did nothing and let it spread freely.
      And the numbers in china was pretty serious already. I dont know what there was to underestimate.

    1. Because they aren’t. It’s hard to think something is important when people using them get the virus, and people who don’t…don’t.

      The real question is, why are non-Americans so gullible as to listen to the media? Or why are non-Americans so idiotic as to think the coronavirus is bad when more people have STILL died from the flu this year lmao.

    2. @Ghost_Troupe did you ever think to ask yourself why South Koreans wear masks and definitely have a greater lower curve once they were hit first with COVID-19 from China? It’s because they wore masks and had a Competent Viral response infrastructure.

    3. Because people are ignorant with the masks…..they put them on, touch stuff, then scratch their face under the mask (I’ve seen this many times in public)……then blame the mask and say it doesn’t work. The masks work, it’s the people who are ignorant in the correct way to use them because the media is too busy lying about what the POTUS says instead of educating the public.

      Just like the morons who wear gloves all through Wal mart…..touch all the items with those gloves, then pull their cell phone out (wearing the same gloves) and put the cell phone to their face. If they get sick, it’s because they are ignorant…not because the gloves didn’t work.

    4. @Forty Six South Korea a very smaller country compared to United States actually has an implemented task force who spray isopropyl alcohol of 60% or more on all potential public contaminated surfaces. The Koreans are used to the Chinese viruses, the West is not.

  5. LORD, I’m so tired of this mess…All I know is for us all to stay safe and do our very best to make it through this!

    1. Your God can’t save you Jesus can’t save you only the devil in the flesh can save you put your blood up for heaven on Earth

    2. @Joey Stokes Spread the truth about the need to wear a mask and you will have saved many lives and suffering. Thanks for your faith,

  6. If anyone needs something to do during all this, I would recommend reading “The Expanse” series by James S. A. Corey.

    Gotta make the best of this situation.

  7. Asians wear mask: Violation of human rights and sick man
    Western wear mask: Our freedom and scientifically

  8. People will only understand when it hits them in the face. It’s like trying to counsel rebellious youths..
