- How far can your germs travel in sneezes? Turns out, it’s not just about the biggest droplets, but also the smaller ones that stay in the air. The cloud of exhaled air that comes out of your mouth when you sneeze can potentially travel farther and wider than previously expected.

Following is a transcript of the video:
Achoo!
Are you sick? Don't you dare sneeze on me!
Do you know how far your germs can travel?
Normally, you hold about half a liter of fluid in your lungs. So when you sneeze, you’re able to spray as much as a water bottle’s worth of mucus into the air around you.
It shoots out of your mouth in the form of moist, germ-infested sheets, traveling at up to to 35 meters per second. That’s fast enough to give you a speeding ticket on a highway. Once that sheet hits the air, it expands, breaking up into snotty strings, then a series of different-sized droplets all trapped in a turbulent gas cloud.
One brave group at MIT discovered that the biggest droplets can travel up to 2 meters- about the distance between your desk and two desks down.
But most other droplets? Those travel much farther- up to 8 meters. That’s about 5 desk lengths!
Not only that: The germ-infested gas cloud is less dense than the air around it. So, it rises upwards, right to where ventilation systems and other people’s unsuspecting noses and mouths await. And even though these are relatively smaller droplets, they’re probably still teeming with harmful pathogens, like the flu virus. Even worse - depending on ventilation - they can spread through a room in just a few seconds, and remain suspended for up to 10 minutes!
Now, if you happen to notice someone around you sneeze or cough, you can hold your breath as you move out of range. But during flu season, that might not be enough, because there are danger zones everywhere- specifically on surfaces like desks, door knobs, and especially steel handrails.
Turns out, the flu virus has been found to survive for 24 hours on a steel surface, and if you touch that surface and don’t wash your hands before eating, you may have just gotten infected.
So, let’s say you show up to work sick with the flu one day, and you start to sneeze. Now, according to one study, you’ll probably infect 1 to 2 other people. You’re clearly showing symptoms of the flu. However, it takes a few days for symptoms to show up in the other people you infect. So, those poor souls unknowingly also come to work sick over the next few days and potentially infect 1 or 2 more people. In an office of 100 desks, this could mean 10 or 15 sick people by the end of two weeks! That’s over 10% of the office.
And all of it started with just one sick person: You. All thanks to the germ-laden cloud you so generously shared.
So, next time you’re not feeling great, and sneezing up a storm, think about your poor coworkers and take a sick day for yourself. And them.
How Contagious Is A Single Sneeze?
This is why I hate people who don’t sneeze or cough in their elbow
@@colonelcat8639
i feel sorry for you.
ColonelCat You know what’s worse? All my family members refuse to cough in their elbow. I get sick from them every time. My dad also never washes his hands...
Digital Cyclone well, 1 week of cold symptoms, 1 day of fever symptoms, then 3 more weeks of coughing-up phlegm.
There's a coworker that I don't speak to. He never covers his mouth during a sneeze or cough. To make matters worse, he spits in the garbage can. Not only is he spreading his respiratory droplets, he's a stubborn know it all and nasty!
@@melanier7309 Sounds horrible.
My sneeze doesn’t go further than my elbow: because im cultured
Anson Hu, that does help a lot but there are still nano particles being spread because your elbow does not fully cover your mouth as you sneeze. At least you have enough respect to cover your mouth because it is so disgusting when you see someone just sneeze with their mouth wide open!! I do my best to pull the collar of my shirt over my mouth if possible. If anyone gets infected it would be me!! Lol
Considering you're a live creature, I have a feeling that the germs will just fester and spread on your body/clothes anyway, and you're likely to spread it some other way after that. At work you're constantly touching and brushing again other things. Better off covering your entire mouth with a napkin or staying home. The likelihood of catching all sneezes whilst sick is pretty low.
And then there are people who sneeze into their hand instead of their elbow.
>_>
@MintyGacha Oof
I told my students to sneeze inside their shirts. It's their goo from their body, so it should stay on their body. And their clothes get washed so where's the hard part?
I suddenly picture a war zone but instead of bullets it's just a bunch of people sneezing
Lol
kremit the frog lol i saw u in the infographics show.
Time to write a novel in which sneezing is the primary weapon used in war.
Achoo pew pew pew pew
lol
This video should be mandatory to watch in all school systems and work place! THANK YOU.
Ok Karen
Mandatory lol ha ha
Coronavirus: You’ve underestimated my power
The sneeze is the new coronavirus
Coronavirus is the new sneeze
0:28 Well you can say that my nose was running...too fast
The door is this wa--
Wait that was actually pretty good.
considering sending this to my mom because she doesn’t cover her mouth whenever she sneezes 🤢
My sister also doesn't.
This video is going to traumatize a lot of people 🕷
Sure, its as dangerous as ebola
Why do I watch these types of videos?
Why do I see you every where I go?
It did
Lol I thought the spiders are real and i was *FREAKING OUT*
Can my sneeze reach the moon?
yes, it can reach andromeda as well
@@WindowsSaturn ;-; well then
Found out that's because you can sneeze in 0G XD
CoolingTool it can travel to 18 light years
It can reach the edge of the universe
This video is just another reminder to COVER YOUR GODDAMN SNEEZES
Exotic_ Dummy thank u 🤦♂️
Me: *WRITE THAT DOWN, WRITE THAT DOWN*
2020: don't give me anymore ideas.
now im never gonna breath in flu season.
What r u? A dolphin? Bring a gas mask.
Good luck on that task
@@aircraft2 good idea
@@aircraft2 not a dolphin but those germs pisses me off 😆
I always take a full tank of oxygen to class.
This video should show up much more on COVID-19 Pandemic
While it might be fine to say "don't go to work" but how many times do employers say to come in as they need you and surely your not that sick. The pressure to still go to work is high coupled with the number of people that feel 'less' if they let being sick stop them from working don't help the spread of infections.
So my sneezes can reach outer space?
If U sneez on an astronaute, probaby.
Oh my god, how do people think such a thing is close to possible. Its like saying my fart causes more global warming than China
Yes. Yes it can. 😂
@@theluluexpress8528 Work on your diet - just a suggestion.
i gess
I hold my breath when people sneeze but try to be slick to not offend them.
Simple solution : Cover your mouth whenever you sneeze 🤧💦👍
This is what happens in class sometimes!
Only one sick person infects the others and gets cured leaving the whole class sick
frr
My school would force me to come to school, even if I got a cold, because you can just sneeze on your arms.
...and stay sick for much longer
i just pretend i'm not sick and then it is fine actually i don't think i have ever been sick.
I literally sneezed WHILE I was clicking this😂
Good.
And this guys, is why taking time off work is important when sick
This should be shown at every job orientation
It would have been great to include how to prevent spreading those germ ridden sneezes from reaching his neighboring desks.... BY WEARING A MASK!!!
The other day a person sneezed in front of me and snot came out, and then it drilled to the floor. I was around food, so now every time I eat I get scared, and I make sure that I sneeze and cough into my elbow.
Thank you for making my germaphobia worse.
Me at school during flu season 1:41
Can i show this video as an excuse?
Probably
I wish my sneeze was as cute.
Who else is watching this during the coronavirus pandemic?
I am
I
I,am
Meee
Not me
or you know, you can just cover your mouth.
If you sneeze on your hands, and touch someone or touch food, that person or your food could possibly be infected.
Use a tissue then?
@@solareclair357 wait how do you sneeze on your elbow? (I really dont know)
@@kimdokja320 you don't sneeze on your elbow. You sneeze on the part between your arm and your muscle which is behind the elbow.
Then wash your hands!
1:31 that's what i do everytime people that is near to me sneezes😂
animations and story line are hilarious!! 😂😂
There is no way that you are able to spray a water bottle of mucus when you sneeze. It has to be in the low single mililiter digits, like 2-3ml per sneeze. Not half a liter!!
Exactly.
GETTING EXCUSE AT WORK FOR SNEEZING
Next video:
*_How far can a fart travel_*
People need to practise common sense when they are sick. I used to have an ex colleague who was sick but she refused to take medical leave and she spread the virus to me and a few other colleagues which made me quite annoyed 🙄🙄😑😑
A water bottle's worth of mucus EACH SNEEZE?!?! Yeah I'm not buying that
Me neither
The sneeze travelled so far it made me sneeze watching this video
You probably made some people tramatized.
I know that when a teacher I had in primary school sneezed in the classroom, I could SMELL it from all across the room, and it happened most of the time he sneezed. It always that SAME smell. So like, yeah we were basically inhaling those germs
Wolf Scent ew
@@Swess2908 smells weird! sickly sweet and musky?
Wolf Scent musty?
@@Swess2908 that too!
gross 🤢
I used to work at a hospital where they thaught us to sneeze into our elbows
Dads: am I a joke to you?
Legend says that the guy still sneezes
Now I know how to stop my friends from sneezing in front of me.
Just cover your mouth during sneezing, dammit! :D
0:55 dang
Since no one will read this I like to tell people to say ahhh and then quickly blast a sneeze directly into their mouth
Ha
ewwwwwwww
hahahah
Wow this comment aged well
What if we sneeze by covering mouth with handkerchief?
Then the handkerchief gets infected and everybody else is safe
stop abusing handkerchiefs
jk
That's sexual harassment!!.. No, it's rapee!! HELP IT'S A RAPEE, HELP!! THIS GUY IS A RAPIST!!!1!!
@@emptytoiletpaperroll9112 huh? R u crazy!!
@@AbdullahHayatKhan It's the favorite line of the feminists
1:36 objective:
SURVIVE
The only person I’m infecting is me, into my elbow. I do it without even thinking about it now!
Moist moist moist moist moist moist moist moist moist moist moist moist moist moist moist moist moist moist
LOL, I sneeze a minute ago before watching this video! XDDDDDDD
The 35 m/s (80 mph for My Fellow Muricans) is deceptive. The viscosity of air becomes a significant factor in slowing down the tiny droplets we sneeze out. Even a small burst of air will slow down quickly. What DOES travel further, is when the burst of air collapses into a toroid vortex, this little donut miasma can travel far (albeit much much slower).
Unless I’m puking up blood my mom will make me go to school
Mood big ass mood
Also higher distance=lower concentration of germs, so, whats the point of this?
So basically I’m going to work now when I got the flu
Because I don’t like my coworkers 😂
In class when someone is sneezing in FRONT OF ME ugh!
I said "get away from me!!! Ughh" or even "what the heck *the name of the Classmate sneeze on me*"
And my classmate said
"Your so arte"
Ugh I hate my classmates I actually wishing to move in other school can't wait
art*
...wait until you take microbiology.
Bosses watching this like, "naw, dont take a sick day for nobody."
“Did you find someone to cover your shift?”
*Intercontinental balistic sneeze*
What about covering your mouth when you sneeze?
Watching this while having a flu.
"Take a sick day" lol what a joke really like many of us are able to do that without repercussions.
Your immune system is laughing at you freaking out
This is the best video to explain why wearing a face mask is so important during coronavirus
Don't work duhhh
I sneezed while watching this video😂🤣
This just shows how disgusting some people are! Like cover your face with your arm when you sneeze, or stay home if your sick. WASH YOUR HANDSSSSS!!!
Why the hell am I watching this! Now I’ll feel even more paranoid when a person 1 seat away from me sneezes!
20:38 thanks for saying im so generous!! 😋
I literally just sneezed 5 seconds before clicking to this vid
I'm going to need some citations for the claims made in this video, other than your social media accounts! Why was the group at MIT so brave? Their supposed speed images look like CGI animations!
Sibling: *sneezes*
Me: *dives into a blanket*
Today in the news, *HURRICANE SNOT*
I disprove that. I have to go to school to learn and if I get someone sick is not my concern. I just want to be successful like everyone else
I sneeze even when I am not sick. Kind of surprising.
Allergic response to air pollutant (dust-- pollen--mold--chemical---++++ )
Because of the allgery's around your area thats why u sneeze when ur not sick
@@GalaxyGamerRBXOffical Well I knew that after that comment from 3 years ago approx. But thanks anyways, even if it’s after I knew that. It’s fine though.
Anyone watching during COVID-19?
0:16 you hold half a liter of liquid in your lungs but you're not going to sneeze it all out with a sneeze. Hilarious
I fuckin hate it that ppl dont understand how disgusting and potentially harmful it is when u dont close ur mouth when u sneeze
Madagascar has closed it's port
I'm considering displaying this in every screen in the world
So let this be a lesson, cover your sneezes and stay home if you have a fever!
*someone about to sneeze*
DON'T U SN-
*sneezes*
welp, time to sit in bed all day now.
1:39 when people so hard to prank you
Well, Mythbusters have busted the past PSA on sneeze can travel over 100mph & over 30 feet.
Their actual results are 35-39mph & 13-17 feet.
For prevention, even if it's not a common cold, sneeze must be contained best into your elbow. Hankerchief is ok for sneezing 1 shot, but DON'T when you're sick.
Secretion spreading wise, yeap, can't be helped when everyday things we touch the secretions will spread far & wide without our knowledge.
I just sneezed and saw this video lol
This is why you put your hand in your mouth when sneezing
Gesundheit! Bless you...
Who else is here after Coronavirus?
Next time your shopping in a grocery store can you're picking out the freshest stack of asparagus think twice.
**remembers my sick cousin sneezing at my face in less than 4 inches earlier afternoon**
I hate when people come to school sick. I caught strep throat from someone at school and had to go to the hospital
Thats why my boss must give me a free day
AND THIS IS WHY PEOPLE NEED TO USE THEIR ARMS AHEN THEY SNEEZE (PLUS DONT USE YOUR DANG HANDS TO COVER A SNEEZE)
2:04 GOD THAT WAS AN INTENSE SNEEZE
And this reminds me to get my flu jab...🙄
I shouldn't be watching videos like this, already hold my breath when people sneeze around me.
i remember having a cold/flu at school for a week and a few days latery classmate all had a cold
Teacher: what did u learn over the summer
Me and the bois:
Or, here's a thought...YOU CAN HOLD CLOSES YOUR MOUTH OR HOLD YOUR ARM TO YOUR MOUTH
