- 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.

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
Coronavirus: You’ve underestimated my power
The sneeze is the new coronavirus
Coronavirus is the new sneeze
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*
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.
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 should be mandatory to watch in all school systems and work place! THANK YOU.
Ok Karen
Mandatory lol ha ha
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.
I hold my breath when people sneeze but try to be slick to not offend them.
This should be shown at every job orientation
Who else is watching this during the coronavirus pandemic?
I am
I
I,am
Meee
Not me
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
I wish my sneeze was as cute.
Thank you for making my germaphobia worse.
Simple solution : Cover your mouth whenever you sneeze 🤧💦👍
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
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.
Can i show this video as an excuse?
Probably
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.
This is what happens in class sometimes!
Only one sick person infects the others and gets cured leaving the whole class sick
frr
And this guys, is why taking time off work is important when sick
Me at school during flu season 1:41
You probably made some people tramatized.
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.
GETTING EXCUSE AT WORK FOR SNEEZING
It would have been great to include how to prevent spreading those germ ridden sneezes from reaching his neighboring desks.... BY WEARING A MASK!!!
animations and story line are hilarious!! 😂😂
Now I know how to stop my friends from sneezing in front of me.
The sneeze travelled so far it made me sneeze watching this video
Legend says that the guy still sneezes
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😂
Next video:
*_How far can a fart travel_*
A water bottle's worth of mucus EACH SNEEZE?!?! Yeah I'm not buying that
Me neither
I used to work at a hospital where they thaught us to sneeze into our elbows
“Did you find someone to cover your shift?”
Dads: am I a joke to you?
Who else is here after Coronavirus?
...wait until you take microbiology.
Awesome video! Visiting here from 2021!!
So basically I’m going to work now when I got the flu
Because I don’t like my coworkers 😂
Watching this while having a flu.
0:55 dang
Anyone watching during COVID-19?
I'm considering displaying this in every screen in the world
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
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.
Unless I’m puking up blood my mom will make me go to school
Mood big ass mood
Just cover your mouth during sneezing, dammit! :D
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 🙄🙄😑😑
The only person I’m infecting is me, into my elbow. I do it without even thinking about it now!
Bosses watching this like, "naw, dont take a sick day for nobody."
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).
1:36 objective:
SURVIVE
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
This is why you put your hand in your mouth when sneezing
20:38 thanks for saying im so generous!! 😋
Interesting video.
I literally just sneezed 5 seconds before clicking to this vid
LOL, I sneeze a minute ago before watching this video! XDDDDDDD
What about covering your mouth when you sneeze?
Also higher distance=lower concentration of germs, so, whats the point of this?
*Intercontinental balistic sneeze*
Next time your shopping in a grocery store can you're picking out the freshest stack of asparagus think twice.
Your immune system is laughing at you freaking out
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 fuckin hate it that ppl dont understand how disgusting and potentially harmful it is when u dont close ur mouth when u sneeze
why did i watch this now im paranoid
Madagascar has closed it's port
This video made me sneeze
Well if i was going to sneeze then cover my mouth when it's going out then wash my hands will it still spread?
Why do I keep watching these types of videos
I don't know if this is a more effective way of keeping my sneeze from spreading to other things or people, but I cup my mouth with both my hands and sneeze. I close both my hands together and walk to a sink, and then I use anything but my hands to turn the handle to rinse my hands. Is this smart or am I just an idiot? This also isn't reliable because haha, there won't be a sink everywhere.
I sneezed while watching this video😂🤣
Thats why my boss must give me a free day
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.
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
Sibling: *sneezes*
Me: *dives into a blanket*
When he said dont you dare sneeze on me i instantly sneezed
Moist moist moist moist moist moist moist moist moist moist moist moist moist moist moist moist moist moist
Blessh you
This is the best video to explain why wearing a face mask is so important during coronavirus
Don't work duhhh
When I got sick, I made the whole school get sick with me
Good video.
So let this be a lesson, cover your sneezes and stay home if you have a fever!
"Take a sick day" lol what a joke really like many of us are able to do that without repercussions.
Gesundheit! Bless you...
Who the hell even sneezes without covering their face ..
That flu virus character reminds me of my life of a teenage robot
Hmm.. looks like i will be having at school
Coronavirus brought me here....
Today in the news, *HURRICANE SNOT*
1:39 when people so hard to prank you
I’m gonna sneeze at my friends
Thanks for sharing
And this reminds me to get my flu jab...🙄
