Corona Virus

Things To Do To get Rid of Corona Virus !!! 

Tt's clear now, that this coronavirus spreads not just through contact and respiratory droplets that

fly through the air like ballistics, but also it's being transmitted through the airborne route meaning

through aerosol so meaning the virus lingers in the air and then someone comes and inhales that

virus into their lungs.

Hi this is yogi, I am yogi i am working inretail field for mare than 10 years, Now it has become very

difficult to get business in in this situation because of this pandamic.

What Precaution To Take ?

 let's face it there is a reason why hospitals with designated covid areas require everyone to wear a

n95 respirator mask as well as eye goggles, that's because we know that this virus has the potential

for airborne transmission, previously the who said that this virus only spreads through contact and

respiratory droplets and doesn't spread by the airborne route.

Unless it was related to aerosol generating procedures, like with an intubation or bronchoscopy or

when someone is using a cpap mask, or a bypass mask it actually wasn't until july 9th that they

formally recognized that it could be transmitted indoors by means of aerosol, or at least they said

that they can't rule out this possibility.

They finally admitted this after hundreds of experts had called on them, to do so and look it's not

like the who hasn't made blunders before on february 25th i read a review saying that this is a

pandemic and explaining why that is , but for today's review i want to start out by saying yes

unfortunately covet 19 is now a pandemic even though it's not official but it wasn't officially

declared a pandemic by the who until march 11th

I don't know why it took them so long, then there was the whole blunder of them saying there isn't

asymptomatic spread, which we already known that it does spread asymptomatically, for like two

months at that point and then the next day they actually self-corrected so why until recently have

they not acknowledged airborne transmission two main reasons one because there is still no

definitive evidence that proves airborne transmission.

Of course it's always nice to be sure about something before making a public statement, but

sometimes you have to take action and implement safety precautions without having definitive

proof, the second main reason is that declaring airborne transmission has big big implications, you

already see how bad things are with masks and social distancing.

In the debate over reopening schools and such well, if this virus spreads by the aerosol route

before i get into that, let's actually start out by defining what airborne transmission really is

because, most people don't actually know what it really means, let's rewind to february 11th when i

red this review about explaining airborne transmission, then there's airborne precautions some

lung infections and some throat infections spread.

When small viral or bacterial particles stay suspended in the air and can be inhaled by other

people, the 2019 novel coronavirus is believed to fall into this category, it also includes other

viruses, like the sars virus, measles, chickenpox and tuberculosis which is actually a bacteria and

then this study came about and i read a review about it on march 18th.

And there's now a new non-peer-reviewed study that just came out, that shows the virus remains in

aerosol meaning in the air for up to three hours now, at this point we don't know how much of a viral load in that aerosol you need to inhale in order to come down with the infection, so that is still

unknown at this point.

So just because it remains aerosolized for up to three hours that does not necessarily prove that

it's an airborne transmission, but i would think that's the case more studies are needed to prove

this one way or another, but let's get more into the nitty-gritty of aerosol transmission, during

normal breathing and speech tiny particles are emitted mainly from the mouth.

These particles can range in size with the smallest being less than a micron and the biggest being

over 500 microns in diameter, now to put some perspective on that the average diameter of a

human hair is about 80 microns, typically droplets that are less than 5 microns are considered small

and it's these small droplets, that can be suspended in the air.

Droplets that are over 100 microns are considered large and droplets that are between 5 and 100

microns are intermediate, but the reality is it's a range of sizes, it's a continuum, it's a spectrum

from less than 1 micron to over 500 microns and more and more particles are emitted when

someone is breathing heavier such as with exercise or if someone is coughing or sneezing or if

someone is shouting or singing.

Due to gravitational forces particles that are bigger than five microns tend to settle meaning fall

down on surfaces such as the floor and they fall fairly close to the source typically, within six feet

this is why the cdc recommends six feet for social distancing, but here's the thing sometimes these

larger particles travel farther than that, especially if someone is breathing heavy or shouting or

singing or coughing or sneezing.

Typically they fly no further than 12 feet in these situations, but we're also spraying particles that

are smaller than 5 microns and this is why tiny particles they don't act like ballistics they act more

like a gas cloud, where they float in the air and travel up to 27 feet the ones that are less than one

micron evaporate within milliseconds of hitting the air while the particles that are more than 100

microns can take up to a minute to evaporate.

So what happens when the droplets that are less than five microns, what if they're spewed from

someone who's infected with the virus and all of a sudden in midair they evaporate, well they dry

out and you're left with a virus that is floating in the air these are called droplet nuclei

Aka aerosols there are lots of factors that determine how long aerosols remain in the air, just like

there are a lot of factors that determine how long a fart will stink up a room , it depends on the

person who emitted the particles, how they emitted them the temperature and humidity of the

environment, now let's take a look at what happens when someone sneezes.

This was published in one article and they took a super slow motion video of a healthy person

sneezing, you can see the varying degrees of droplet sizes the, larger ones fall to the floor like

ballistics but the tiny ones remain airborne, in this wet cloud if you will not only does this wet cloud

help keep the virus viable for a longer duration, but this cloud can travel about 23 to 27 feet

depending on the conditions lack of airflow.

Means that this cloud will persist longer and when this moist cloud finally does dissipate, you're still

going to have droplet nuclei that stay airborne for about three hours, based on that nih study a lot

depends on the airflow of that environment, this is the reason why scientists in china actually found

the cyrus coronavirus.

Viral particles in the ventilation systems of hospitals that had coveted patients in it, now proving

that airborne transmission exists is actually harder than one may think, the best way to prove it from

a scientific standpoint would be to line up a bunch of people in a room who have covid.

Okay and then you line up a bunch of other people who don't have covet keep them 20 feet apart

from each other and then let them stay there for several hours and see who gets coven, obviously

from an ethical standpoint this is what we call, but what we can do is look back at real life situations

that sort of mimic this scenario, like for example what happened in this chinese restaurant.

In this study they reviewed video footage after, they realized that three different parties ended up

being positive for coronavirus,what they realized was that there was no evidence of direct or

indirect contact between the three parties, who ended up getting the virus their results effectively

showed, that the infection distribution was consistent with airborne transmission and they even

recreated this scenario using a warm tracer gas and computers to simulate the spread of exhaled

droplets from the index person.

Meaning the person who is spreading it to other people and when they did the simulation they were

able to recreate that scenario and then there was this, in a semi-rural area 60 singers convened for

choir practice mind you this area was not a hot spot they didn't have any known cases at the time in

this area, all the singles were feeling fine they were in good health that day.

No one was known to be coughing or sneezing hand sanitizers were provided they took measures

to socially distance presumably six feet and they avoided hugs and handshakes and proceeded to

belt out the high notes, now on to the sad part within three weeks of this event 45 out of the 60

were diagnosed with covid and two ended up dying.

So what was the conclusion it was that most likely this spread was due to aerosolization and

recently three passengers on a delta flight came down with the virus although we don't know the

details and this doesn't necessarily prove or disprove airborne transmission,

so at this point we might not have 100 conclusive evidence that proves airborne transmission, but there are nowseveral studies that strongly suggestthat to be the case it's just like in a murder trial.

If you have enough circumstantial evidence you can still paint enough of a picture to get a

conviction without necessarily having a bloody fingerprint now just because we know that this virus

spreads through the airborne route, that's not to say it doesn't spread through contact and

respiratory droplets meaning bigger droplets that act like ballistics it spreads by all three of these

mechanisms.

So hand washing is still important as is not touching your face or mask with dirty hands and

maintaining six feet apart is a good thing but it's not good enough for certain situations remember

earlier, when someone sneezes that moist cloud containing aerosols can travel up to 27 feet and

the virus can linger in the air for three hours.

Well what good is six feet going to do you in that situation, it's better than no distancing, but it's not

good enough, now some rooms have adequate ventilation that supply clean outdoor air and

minimizes recirculated air, the better the ventilation the less likely the spread of aerosols and even

cracking open a window can make a huge difference and having a fan blowing is a good thing too

and generally speaking opening doors is a good thing

Other measures can help too like having an air purifier with high efficiency air filtration and

germicidal uv lights and by the way if you're ooking to buy an air purifier i recommend to go get one

that has a filter that can filter out particles of less than 0.5 microns.

so when you're outdoors or indoors with good ventilation the virus is much less likely to spread via

the aerosol route, especially if you're at a minimum six feet apart and there isn't over ande specially

if everyone's wearing a mask.

Which Kind Of Masks Is Safe

 

Now let's talk more about masks i want to bring up to you'r notice that this very impressive study

was published june 30th now in this study they set up a dummy and created simulations of coughing,

first without masks and then with different types of masks or face coverings if you use tracers to

visualize, the cough in the cloud that forms as a result of the cough it showed that the cough

expelled the gas up to 12 feet in a span of 50 seconds.

After that they covered the dummy's face with different types of face coverings, so without a face

covering the average jet distance was eight feet and the maximum was twelve feet with a bandana,

made out of elastic t-shirt material.

the average distance went down to about three and a half feet, with a folded handkerchief that was

made out of cotton it was about one foot three inches and, with a stitched mask that was made out

of quilted cotton it was about two and a half inches and, with a commercial mask specifically a cvs

cone face mask it was eight inches and, with this medical mask or surgical mask you could assume

it's going to be about 8 inches.

Now mind you in this study the tests assume that the mask is properly worn and not saturated with

water or sweat which can affect the distance of the jet propulsion, so these types of masks are good

at helping to mitigate the spread of the virus to other people are they perfect atdoing, so absolutely

not but they do make a big difference what they don't do is prevent you from inhaling the virus,

because where there's openings that's where the air gets sucked in and that's where you can

inhale it.

But if you have an n95 respirator mask or an elastomeric respirator then your chances of inhaling

that virus go down dramatically at 95 ,respirators are tight fitting and filter out at least 95 of airborne

particles as small as 0.3 microns and elastomeric respirator is a reusable device, with exchangeable

cartridge filters, so like an n95 respirator it also filters out at least 95 percent of airborne particles

as small as 0.3 microns it fits tight against the user's face.

It is more comfortable than an n95 before reusing the mask all of its surfaces do have to be wiped

down with a disinfectant, so although both of these are not perfect, they are very effective at

preventing inhalation of the virus, but there are a couple of issues with the n95 for one they're hard

to come by because they're being reserved for healthcare workers. 

They're also uncomfortable and as you could probably tell your voice gets muffled and they cansort

of hinder your breathing or make you feel smothered also, they have to be properly fit on your face

and in order to do so, that means you can't have facial hair in this region the cdc actually has a

diagram of what facial hair styles are compatible with the proper mask fit,

When i go back to work i got to shave all this in order for me to have a properly fit n95. but wearing

one of these n95 masks for long is not practical for most situations for the reasons i just mentioned,

with that i do wish that there wasn't a limited supply because lots of people would benefit from

wearing one.

In certain situations like for example whenever people are in an enclosed space, like elevators

small rooms and airplanes and i do want to talk about flying on an airplane because there's actually

a lot to say about that there are pros and cons to both flying versus driving, when it comes to

preventing getting covered.

If you're worried about getting the virus especially if you're in situations that have a high risk of

airborne transmission then i'd say yeah so if you have to fly in an airplane which i might actually be

flying pretty soon, but what i plan on doing is wearing my n95 mask along with my motorcycle

glasses and with the n95 the chances of me inhaling the virus are pretty slim.

If you don't have an n95 then the elastomeric respirator might be an option for you, you can

minimize your chances of inhaling the virus and other viruses as well powerful if you want decent

looking goggles or glasses to prevent the virus from getting into your eyes you can get

Conclution 

So let's summarize if you really want to maximize your protection from this virus there are things

that you can do and i'm not saying all these things are practical, i'm just saying that this is what you

can do for maximum protection the first thing is to avoid people not always possible

but away six feet is better than nothing.

But still not great 12 feet means you're not going to get any of those droplets spread into your

mouth and nose in that ballistic form but 12 feet is still not enough to prevent airborne

transmission, so for that you really need 27 feet or so and that's going to depend on various factors,

all right the second thing is if you're unable to avoid people

In a situation where airborne transmission is possible, wear protective eyewear in either n95 or

elastomeric respirator the third thing is if you're around people better to be outdoors ,if you're

indoors or around others try to open doors windows, consider having a fan for better circulation,

hopefully there's good ventilation in that room and you can also consider getting an air purifier with

hepa filter for that room okay

The fourth and final thing is, if you don't have a respirator mask a surgical mask or a medical mask

mainly helps to prevent you from spreading that virus to someone else, however it does offer some

protection from respiratory ballistics being sprayed into your mouth and nostrils but this won't

prevent you from inhaling the virus.

If it's in the air around you if windows not opening , no i locked them so we could get a good

clambake going on in here ,so i'm going to wrap this one up but my next one's going to be

dedicated towards travel airplane versus car ride pros and cons so definitely.
