Why face-to-face interaction may spread COVID-19

nosoccermom

Here's a video that shows how speaking to each other face-to-face can transmit the virus --- and why physical distancing works. They used a laser to illuminate the water droplets that contain the virus are emitted while speaking and can potentially be inhaled by the other person:

The scary part is that people can transmit while they are not exhibit any symptoms.

So, do not talk face-to-face with friends, neighbors, or anybody you encounter. Keep your distance. Make a phone call, skype, use facebook, instagram, facetalk, or any of the many other ways to stay connected.

The main reason we are social distancing is...because THERE ARE NO MASKS.

And there are no tests.

We were promised millions of tests by now. Remember?

What if we call it "social energy" instead. Social energy is free, renewable and readily available. What's not to embrace?

No, we are not. Stop spreading falsehoods.

Ever watch a live performance up close? The spit just flies.

I sit in the front row of my local professional theater, it's very close and intimate. The spit does fly, but I haven't felt it me. But who knows?

Mostly they seem to spit on each other. Occupational hazard.

Really? Then answer this:

Can you tell me where i can buy masks so my SO can protect people around him while he is going to his " essential job"?

Can you tell me where he could be tested so that he knows to self-isolate if he is a carrier?

Very useful video. Time for some homemade masks...not so much as to be protected from others but to protect others from us....

We need testing before we can ever get past the worst of this thing.

Chisue, in your situation you need masks. Look on Light in the box, Wish, DHgate, EBay , Etsy, Amazon etc. You can buy singly, in pack of 10, 50, 100.

Mine came from Lightinthe box.

I don't have kids, but my DH and I are in it together. No way could one of us avoid it if the other brings it home. And if one of us gets sick, the other will have to be the caregiver. If both of us get sick, we're screwed.

Useful and interesting video, but incomplete information.

What the video cannot show is that when someone speaks or sneezes, there are particles much much much smaller than droplets which will not show up by the laser beam. A COVID-19 virus is, I think, 125nm in size.

Particles that small will float in air for days by air movement and Brownian air molecule action from one end of the room to the other.

Where is it written that social distancing is unnecessary if one is wearing a mask?

Social distancing is not a critical concern for medical professionals because they are wearing a medically approved face mask and eye protection..

Face-to-face talking spreads the virus, especially from asymptomatic people --- who are not coughing or sneezing.Limiting face-to-face contact works. Period. Unless you can meet and not talk.


Note: A simple cloth in front of the speaker's mouth stops the droplets that accompany all speaking.

Healthcare workers should probably wear masks when they are at home.

Regarding at home: I would wear a mask if I were still out and about, talking to a lot of people.

Here's what I told my parents who are well into their 80s and are holed up at home:

1. Talk to your friends and relatives by phone, email, Skype, text.

2. Don't talk face to face with your neighbor, even if she reassures you she has no symptoms.

3.
Insist that the healthcare aide who stops by wears a mask and washes
her hands as soon as she enters
. And keep your distance as much as
possible.

My parents aren't out and about, so this is to protect them from the healthcare aide, who's visiting others, going shopping, has a family at home AND may be infected without exhibiting any symptoms.

Fortunately,
it's much easier to catch the droplets at the source, i.e. speaker,
than to prevent inhalation once the droplets are floating around. So the
dust masks left behind by contractors are fine --- as are cloth masks.

4. Ditto the neighbor who brings groceries; the pharmacy who delivers meds or anybody else they need to interact with.

They have to put a mask on or leave the stuff at the door. Or shut up!

Note: The HVAC repair person showed up with mask and gloves. Yay!

Specifically @dcarch:

Important point indeed! When someone sneezes, the particles emitted are NOT naked viroids but heavily hydrated small droplets. When the water layer around them evaporates before they hit the ground, they are indeed much reduced in weight, and become what is referred to as aerosol. At that point, only an N95 mask would be able to protect a receiver. Chinese studies claim that aerosolization may occur but is at best a minor component of transmission for COVID19.Aerosolization is a major component for other diseases such as measles, of course, but reportedly not for COVID19.

Note, however, that asymptomatic carriers do not sneeze or cough, so the paradox is "how can a person without coughing or sneezing" (and we're all on the lookout for these!) transmit disease. We are 100% confident that speaking, and contamination of surfaces through speech-generated droplets, is the key.
