COVID 10: Is COVID-19 an airborne disease? Will we all need to wear face-masks against SARS-CoV-2?

There seems to be a lot of confusion in the droplet versus aerosol discussion and how these relate to the spread of COVID-19. Is it airborne and inhaled or droplet based via fomites and hands? The uncomfortable truth is that we have evidence for both modes.
In this video we first define what a droplet and an aerosol is based on their behaviour in the environment. We then examine both through the findings from two published studies. We will also discuss how long viral particles survive and stay viable and able to infect after they fall on a surface or get suspended in the air.
For COVID-19, we agree that the various transmission routes may predominate in different settings. The airborne route is relevant for hospitals and hospital staff as well as crowded and badly ventilated public spaces. Everyone else is more likely to get the virus through touching surfaces, bad hand hygiene and then touching their face.

I'm a Biology researcher doing my PhD, and this is by far one of the most reliable videos I've watched about COVID-19. Not only does it support the accuracy of its statements with reliable sources (eg. peer-reviewed research papers) to explain an important epidemiology concept, it also practices critical thinking----it does so not by answering a question, but laying out what has been reported in the research field, and more important, and what remains unknown but calls for answers.

In that sense, if the data can be peer-reviewed and, even better, reproduced, then the data is more convincing than untraceable information from the social media which can be politically manipulated. Nonetheless, this is not to say that all data are accurate or reflect the truth. Data only reflects what the experimenter observer.

hello thank you for the vid, so i just wanna understand, are you saying that although the main way of spread is by coughing and snezzing, the virus goes relatively quiclky to the ground and so its when we touch still active surfaces with the virus and do not clean our hands and touch our faces that it infects us ? and that actually catching the virus by inhaling is less common and that wearing a mask needs to be done very carefully cuz then the mask itself becomes a surface that may have the virus and if we touch the mask and then our face without cleaning our hands then again we get infected? and so its actually just better to wear no gloves or no masks and just not touch our faces unit we clean our hands , especially if we go out to stores or in crowds?..plz explain Lisa

[@nedi6188]

this might be a dumb question but if ventilation is the key can it be a way for the virus to enter your home as well, for example if I open the window and lets say my window is close to the road/sidewalk and a covid infected person pass by and cough the aerosols can still be push in my house thru the window correct? I've watched some video that its not that easy, they say that outside the virus experienced a lot like sunlight mosture and wind that the aersol breaks and the virus eventually become unviable but still it confuses me if its safe to open my windows. Our house is design where our windows are close to the streets so I'm afraid if letting air inside our house is safe cause their is fair amount of people passing by.

[@guytelfer1353]

So moisten the air in hospitals with humidity, or do you have to be taught how to evaporate water, humidifying the air will weight anything airborne down

[@moonbear5929]

I tend to disagree about that. A virus is sealed in a layer of essentially fat, which has to have moisture to be effective. This fat layer helps protect the inside of the virus. As they said in the video, the virus can live for days on plastic, second on steel. For some reason copper seems to kill it faster than steel. But the virus lives the shortest on things like paper, cardboard, fabrics. My theory for this is the porous materials tend to draw (wicks) out the moisture from the "body" of the virus thus drying it out and killing it. The virus wants to live in a dark moist and warm place (like your lungs). Humidifying the air would only help the virus live longer on all surfaces, no matter where it drifted. It would only aid in viruses replicating themselves making them even more plentiful. I'm thinking the opposite, dry everything! Heat blast anything that can take enough heat to kill the virus. Detergents work to break down the fatty layer a virus has, so washing as many things as you can with water and a simple detergent (dish soap, laundry soap and the like) will help kill the virus. Wash down everything as often as possible, wash the floors when you can, counter tops, walls, bed railings, head boards and foot boards, the whole dang shebang! In a hospital, they should have a constant cleaning crew washing things down, the most touched objects, cleaned. I never see cleaning crews in hospitals. I have seen dried blood on floors that you could tell had been there for days if not weeks. I never see them spraying and wiping down anything. I might see some one sweep the floor or actually mop it once in a while. Hospitals are supposed to be clean places, but really, they are one of the dirtiest places you could hang around in. I hate going to hospitals, I never feel comfortable there.

[@guytelfer1353]

@@moonbear5929 excellent, I was leaning towards using the heavy moisture in a way toward washing the virus downwards, I would recommend using the sprinkler systems in buildings to disinfect or send humidity maybe in vapor form and involving pesticides and insecticides, without being able to visually see a virul particle we're assuming it's everywhere and airborne unless you have an electron microscope I'm sure it's carried by insects(bedbugs, nats, mosquitoes, ect) recommending crop dusting everywhere at this point using DDT and other chemicals is less harmful with education about these chemicals and warnings to the public when spraying areas , they burnt everything after the black plague

Yes, the viral load was lower outdoors, that doesn't really need a study but it makes a good baseline. What is important is, is this enough to infect someone? Could it even be beneficial? Would it give the body a chance to identify it while not enough to overwhelm the immune system...or is a tiny amount enough to take you out since we have no immunity.

[@CRAZYCR1T1C]

It doesn’t work like that I am afraid. Your immune system only kicks in when the virus multiply and really show up in numbers. You can still be fully infected with just 1 virus particle. The probability is extremely low. It’s all about probabilities with huge numbers involved.

Well, I am no doctor. But logic tells us, first have something that you step on when you leave the patient room. A tray of 1/2 inch of rubbing alcohol. To get the virus off your shoe bottoms. Go to changing room. Take off outer clothing, and hang, and spray with Lysol. Then have alcohol trays your dip your gloves in. Then take them off. Leave room. Then have a fan blow viruses out the open window. Make sure the fan is not on when you are in there. Wash your hands after you leave room.

[@maxtabmann6701]

What is unsatisfacory in the testing of surfaces is the question whether the reason is the material type or the speed of water evaporation. Naturally, a cardboard will dry quicker than polished steel or plastic. Copper is special because it is toxic. If it is the water and not the material type, then humidity is a more important factor.

[@luiscarlosmoreno7136]

Microdroplets present in the air can be reduced by applying a water spray or water with disinfectant with the necessary care, especially in places with crowded people. The contaminated drops are hydrophilic and can coalesce and fall to the floor by applying a spray on the air with the risk of contamination. Only the surfaces and floors are being disinfected, however the air that is the main source of contagion is neglected. Thus, the rate of contagion by coronavirus can be appreciably decreased.

Yes it would. Look at Taiwan vs. the U.S. One implore their people to wear masks while out and about, and the other doesn't. And then look at the difference between their infection rates.

[@louf7178]

I know this is off topic, but is there knowledge of how many COV-2 viruses be inhaled before it surpasses the virgin immunity system's reaction time? 1? 1000? And, is one able to build immunity at this point? Avoidance seems futile at this point (and lockdown simulation is shown to be useless after a certain infection volume).

[@YoTone21]

So essentially people who go to the beach have a higher risk because of the windy conditions nd the heat?

[@YoTone21]

Assuming going early in the morning before people get there wouldn’t work even tho it only stay in the air up to 6 hours?

[@listen2meokidoki264]

If infected, which mode (or pathway) the virus enters would be:- a) The slowest route to infect the lungs. b) The slowest infection rate. c) The best way to be infected - if someone does get infected. d) If someone was deliberately INNOCULATED, for whatever reason, and the FEWEST virus particles were introduced into the person, what pathways would be optimum? Eyes, nose or throat?

This week a one year old baby has contracted Covid 19 from supermarket shopping. Based up behavioural traits and how many people (esp at present with substantial set distances between individuals ) we can conclude that there is little doubt that either the virus seems to be airborne , or as we know for sure it resides in contagious doses upon objects ( likely the handle of the trolley , presuming the baby was within reach of it being pushed around ) The former is the most likely conclusion . Definitely suggests airborne and more contagious than suspected previously.

[@itorapadas]

Lancet just released a study, one year after this video was posted. And the findings are THE SAME. Covid19 according to the March 2021 is BOTH airborne and aerosol.

[@nofurtherwest3474]

Excellent video (abrupt ending though). I want to invent something to solve this problem. But part of the problem is cultural and really a willful ignorance within western culture, so it will require a paradigm shift in thinking, similar to how we used to not wear seat belts to it becoming 2nd nature.

[@anindya2010]

Why is death rate so low in Australia?

[@akimbo139]

Less obesity, healthier outdoors lifestyle, vit D from sunshine, younger population. 3/4 victims in the UK overweight...

[@mariseg9637]

yes yes

[@Desperado070]

Even 1 is 1 to much... After 24 hours that 1 has turned into 281.474.976.710.656.

[@Jarrettfan]

How about using FAR UV-C?

[@louf7178]

Effective*

[@billtanth6273]

I haven’t used a public restroom since February. When a toilet is flushed it sprays aerosols

[@audioaddict420]

Thank you for this. I've been trying to explain this to people but they don't want to listen cuz I'm only an in home care provider they look at me like I'm a maid and it's dumb I care for pretty sick disabled elderly people most of us IHSS providers are full aware of viral contamination lol we clean it up every day.

[@reachbothpanha6494]

Your information useful more than WHO information

[@Pinkielover]

yes... it can stay in air for 3 hours

[@Machster10]

This is why you need to be wearing a real respirator when entering a public building. You can buy a half mask elastomeric respirator with P100 filter (HEPA) cartridges online. About $30 to $50 bucks. North and 3M are both well known elastomeric half mask brands but there are others. If fitted properly and there is no beard growth, and a good face seal, they can provide 100% filtration of virus particles. The next best is a N95 or P95. They provide up to 95% filtration down to 0.3 microns (individual virus particles 0.15 microns are rare, they are usually stuck to other particles or water so they are larger). If you have questions check out the NIOSH website. They approve respirators for OSHA (the agency that protects workers who work in hazardous jobs such as asbestos). Make sure the respirator you wear is NIOSH approved. They have a posted a useful table of international testing on various brands of N95s. Face coverings won't protect you because they do not filter the air you breathe.

[@kayummiah5017]

I think i came across a person with covid 19 but i was outside the door of my building and the person in the car window open for 5 seconds, what is the likelyhood of me catching it?

[@SRY473]

Probably very small. They say that to catch it, you need to have prolonged, close contact with someone that is infected. It's not just a question of whether you were exposed to the virus, but a question of the viral load - how MUCH virus you were exposed to. So if you're in close proximity to someone that's infected for 15 minutes, you could get enough virus to be infected. That's why they don't want large groups of people gathering together. I wouldn't worry about it. Just be alert for symptoms and do your best to practice social distancing and good hand hygiene.

[@kayummiah5017]

ladycelosa2 hey thanks for the message it gave some ease, I haven’t got symptoms its been a 8 days, im just waiting i guess for 2 weeks to be over, longest 2 weeks ever. Our house is almost run out of food we didn’t stock pile like other i wish i had now. We haven’t gone shops or delivery over a month, i had to make a trip to atm to put money in once but my car didn’t start battery died lol

[@SRY473]

@@kayummiah5017 Yeah, you're probably fine - except for the food part. I really doubt you were exposed. Do you even know if the other fellow was infected? It doesn't sound like he or she coughed in your face or anything. I'd think you could go shopping for food with a mask. Just make sure you also wash your hands. Some people say you should even disinfect the groceries. Don't want to transfer the virus from something to your hands, then rub your eyes, nose etc. The hand to face transfer might be more dangerous because you might have more of it on your hands than whatever was or was not in the air. Luckily, it's easily killed by hand sanitizer or soap and water for 20 seconds. It's a scary time to be alive, that's for sure. They can't develop a vaccine fast enough. Sometimes I wish I could wear a Quarian encounter suit (if you've played Mass Effect, you know what I'm talking about - if you don't, look 'em up for a laugh.).

[@kayummiah5017]

ladycelosa2 yh iv always been the type to keep hygiene you could say im a germ freak, in terms of food when we did buy we washed everything and chucked all packaging and put the contents inside into a separate container or bag, might have to repeat that, and yes iv seen the suit i have not played the game though actually i think i played it once it came with the xbox i got but i have to say im a PlayStation guy.

[@kayummiah5017]

ladycelosa2 and yes it is such a scary time to be alive it is balancing all the wrongs humans done just incase im not talking about the lives it took because my prayers are with those but im talking about the financial crooked market, im talking about the all the pollution and chemicals being pumped into us via air/food/ products, we are radioactive. But i know its difficult and i am scared. I hope everyone can recover this.

[@sylviajustice5013]

The problem with a mask is, you breathe in the air around the sides of your masks. That is the same virus air, that would be in front of your nose, without a mask. How does that help?

[@user-tz4yj2bz8w]

Basically all a waste of money and time. Just get exposed to it already and let your body fight it off. Can't remain in hiding from this shit forever

[@laurapoisel4282]

In turbulent flow, let's say, is it possible for the infinitesimal aerosols from Covid19 to coalesce with other airborne microparticles? I'm aware of the chiefly laminar fluid flows of droplets, but the turbulent flows of inviscid fluids, now interspersed with the Covid19 material, is rather concerning. Navier/Stokes, anyone? Lol

[@akimbo139]

There's a study going on somewhere looking into whether covid particles could hitch a ride on diesel particulates. If people were informed about the harm from particulates, city dwellers would all be wearing masks anyway... Maybe more people will become informed about the subject through this crisis and keep wearing masks afterwards. Biggest co-morbidity factor? Obesity. We might want to look at that too...

[@rollzolo]

I caught it from talking with someone.

[@sushilbarua8862]

Actually I think not only mask also glasses .not a plastic globes only gloves which we use in winter

[@hustledude]

In other words, we’re fk’ed.

[@KarateLauren]

im from the future and can confirm this

[@cathie9614]

My thoughts on covid 19 . Wear a face mask when you go out plus gloves. Then when you come home take everything off even your clothes, in your basement, then go shower. You should put clothes in the washer before showering. Good luck and stay safe.

[@anasifre2479]

NO GLOVES, PLEASE. UNLESS YOU WORK WITH PATIENT OR CHEMICAL PRODUCTION.

[@malikastone]

@@anasifre2479 Why are you saying no gloves? I wear a mask and gloves whenever I go out (grocery store only), and I will continue to do so. Its protecting my hands from virus that could be on surfaces.

[@anasifre2479]

@@malikastone why are you using gloves?? You only use gloves when you work with chemicals, treat a patient, fluids or you have a cut and can get exposed to blood. Why you are using gloves? You don't getvthe virus touching surfaces. You getbit when you touch your face or aerosol. The skin is the portal for the virus. Those gloves have to be tras in a biohazard containment. Why no gloves? Because you wash your hands and that is enough. Doesn't matter where you dispose the gloves, they have the virus. And you don't know who can touch it. If you dispose then in your house, you probably has the virus in your trash.🤷‍♀️

[@malikastone]

@@anasifre2479 Go to 1:43 in this video and you'll see that this virus can be picked up from surfaces. As per several studies, the virus lives on cardboard for up to 24 hours, plastic for more than that, and hard surfaces (ie. stainless steel) for several days. Please educate yourself about how this virus is actually transmitted.

[@malikastone]

@@anasifre2479 By the way, I disinfect our gloves prior to disposal. The disinfectant stays on for 2 mins. I then put them in the trash. So no, the virus is not sitting on discarded gloves in my trashcan. Besides, no one in my house touches things once theyre thrown away. Maybe you play in the garbage in your house, but we don't do that here.

[@rebeccashinhmar7165]

I made my own mask. Put facial wipe under a cotton scarf or surgical mask placing Andrex tissue around the edges carefully. I think we all need to be extra careful and wear a mask & gloves when we go out. Better to be Safe then Sorry. I wish everyone to keep safe and sound. We can only do what we can . Isn't it

[@EzzeKez]

You are right. Let's do what we possibly can.

[@atomicplaygirl66]

Then wouldn't cig smokers be super-spreaders? That is basically what they do.....They deeply inhale and forcefully expell out into the surrounding area. Doesn't that mean that that cloud of expelled smoke is also filled with possible contaminant? Where I work they all sit smoking side by side on a bench in a tiny designated room. But no one has gotten covid19. 😕
