I still don't get why if it works for outbound it wouldn't work for inbound.  I'm not an engineer but it doesn't make sense in my mind.

Wearing a mask doesn't mean you can't pass the virus. It reduces the chances of you passing it. Think of you sneezing into your elbow vs. sneezing into the air.

Please explain to me if by wearing a mask reduces the chances of me passing the virus why doesn't it reduce the chance of me obtaining it from someone else if I am wearing the same mask that is said to reduce the chance of me spreading if I had the virus.  I'm not saying I oppose wearing a mask.  I just don't understand how it can help the spread but not the obtainment of the virus if it is the same piece of cloth.  To me, it either does none or it does both until someone can explain it to me why it can only reduce the spreading.

The masks prevent (most of) the wearer's germs from spreading into the air and landing on things everyone else touches, because it catches the infested droplets. It does not filter airborne particles, once the droplets evaporate. Most people are presymptomatic (contagious and not showing any symptoms) for a couple of days. Many people in the 20 - 50 year old range are asymptomatic (contagious but not showing any symptoms throughout entire infection).

Here are a few paragraphs from this article:

The researchers asked nine study subjects with documented cases of influenza type A or B to test two different types of masks — the standard, disposable surgical masks and a more costly, respirator-style mask. The flu patients coughed into a petri dish while wearing both types of mask as well as without the mask. The dish was then tested for the presence of flu virus. When either type of mask was worn, no virus was detected on the petri dish.

“Surgical masks are designed to trap respiratory secretions (including bacteria and viruses) expelled by the wearer and prevent disease transmission to others,” the study authors wrote. “Surgical masks are not designed to prevent inhalation of airborne particles.”

Researchers say the masks likely aren’t as effective in protecting people from catching the virus because most flu appears to be spread by large droplets or through hand-to-face contact. But when it comes to preventing the spread of flu in the home, families may benefit if the sick family member wears the mask to prevent further contamination of surfaces and to reduce the risk of a cough or sneeze spraying droplets on others.

A read an article similar to the NYT article, but it was talking about surgical mask vs either homemade cloth masks or cloths masks purchased.  Some folks, like Sen. Tim Kaine (D-Va) are just wearing scarve/bandanas tied around their face. The gist was that all the cloth masks are pretty weak at doing much of anything.

Yeah, I don't quite get how wearing one can stop something from going to someone else but can not stop from compromising yourself from someone else.  Its the same cloth.  How can it work outbound but not inbound?

Years ago when my wife was changing a diaper on our 6-month old baby boy, he inadvertently sprayed her face with urine.  It happens!! If a clean diaper had already been in place, it would have reduced the baby's spray range, even though he might have still peed.

Now consider a dozen 6-month old boys playing together in a day care center.  If no one is wearing a diaper, they might eventually pee on each other, unless you could keep them separated at a distance. But if they are all wearing a diaper, their pee will be somewhat contained, even when they get closer to each other.  If their spraying urine droplets happened to contain a 'contagious' germ, wearing a diaper would be somewhat helpful to contain those germs from spreading so far.

Supposedly the coronavirus is spread by saliva droplets (like the baby's pee above) which inadvertently spew out from people whenever they cough, sneeze, or even talk.  Wearing a cloth face mask works similar to a baby's diaper at reducing the range that those coronavirus droplets can travel toward other people.

Of course, the baby's diaper doesn't protect him if another baby's contaminated pee lands on him, but at least the diaper reduces the distance that any baby's urine can spray outbound.

Yeah, you kinda backed my claim with a caveat.

Here is a quote from that article.

"So clearly cloth masks will affect both what you breathe in and where your breath goes when you breathe out."

Well, if you believe what you read to be true, then what I had been questioning about what others have said is accurate.  The mask works both ways and not just one way.  Whether that is enough to stop the bad guys from getting into your respiratory system or not is for a different discussion as I never questioned that.  I only questioned these beliefs of one way masks.

Thanks for the research, Krisitin.  I was too lazy to do it myself even though I did see the headline for that article today.

A simple thing like everyone wearing a mask will help fight off this virus. As you see if the person carrying the virus doesn't wear a mask it makes it tough for everyone.

I am not worried about the flu because I have lived through it a few times in my life. Even with shutting down the economy, social distancing, wearing masks, etc., the Corona virus has killed 98,306 people in the US in less than 5 months and the Flu killed 34,157 people in the US the entire year last year without shutting down the economy, social distancing, wearing masks, etc. The Corona virus has killed almost 3 times as many people in less than 1/2 the time, even though drastic measures have been taken to slow the spread of the corona virus, that are never taken with the flu. Simple math tells me the corona virus should be taken more seriously than the flu.

If we could get the medial professionals, the politicians, and the media to agree to a story, there would be less hysteria.  My biggest concern is I don't feel comfortable there is a method to treat me if I obtain the virus that has a very high level of confidence that I will not have serious life long impact or death.  I am more worried about managing the ailment successfully than having a vaccine.

Source for diagram?

[slaga]

Lifted from Facebook. I had no doubt that the numbers were somewhat fabricated, and I knew it before I posted it, because different viruses, bacteria, etc. are different sizes. Larger particles are more likely to be filtered than smaller particles and the numbers would increase or decrease with respect to the size of the virus, bacteria, etc. I do fully believe the risk drops similar to how the diagram shows, just not the exact percentages.

[Kristin Meredith]

Lifted from facebook -- my first source for competent medical advice.  So we don't know the distance between the wearers of the mask either I presume. And eventhough you now say you doubt the percentages given, you did not provide that caveat in your original post.  This is why I am so skeptical of info on this issue.

I don't think I have ever gone to Facebook for medical advice, competent or not. The caveat was not needed, as the diagram was generic.

Aren't you the one asking a bunch of pellet grilling BBQ lovers (on the internet) "competent medical advice" on in whether or not gargling with alcohol will kill the corona virus in your throat to prevent you from contracting it?

The masks do not have a check valve that allows the virus to go one way and not the other. They are not one way. The virus can enter your body through your eyes, ears, mouth and nose. The virus mostly leaves your body through your mouth and nose. When someone wears a mask correctly, and they are contagious, most of the contagion is caught in the mask. Any contagion that makes it by the mask can enter another person through their eyes, ears, nose and mouth, unless they are wearing a mask. Then they are less susceptible to breathing it in, but they can still get infected if it enters their eyes or ears. Catching the contagion before it enters the air is more effective than trying prevent it from entering your body by wearing a mask, hence the diagram I posted is correct although the actual percentages are subjective. In other words, the mask covers most of the ways a wearer can transmit the virus, but only 1/2 of the avenues the wearer can contract it, and the type of mask makes a difference in the amount of the virus it catches.
