- It's time to start going through a variety of common viruses, so let's start with the most common one of them all, the one that most often causes the common cold. It's called Rhinovirus, and it is a member of the picornavirus family. What does that mean? What are these like? How do they operate? Let's learn all about rhinoviruses!

anyone else with a cold watching this just for the fun of it?
I went to the hospital yesterday and I'm confirmed to have it
Here😂
CZcams: yes this must be about coronavirus, demonetization
The Imacold Variant is running rampant! Kleenex sales are up worldwide 🌐
CZcams:
Enteroviruses= I sleep
Coronaviruses= 👀
Watching this while having a cold 😪
Same :(
Me too, hope you’re feeling better by now!
Same- x(
So there are 100 different serotypes of this thing? That's crazy if you think about it
We meet yet again
Just Some Guy without a Mustache so you again...,
Yep, 100 types of those little bastards which give you a stuffy nose
That's why you will never be immune to them
I was getting ready to work on a corona virus debunk video, I'm glad you covered this topic, it will definitely help
Hey Team!
Team Skeptic!!!! Love you bro. You were the very first channel I subscribed to on CZcams. Ever.
@ Think you got the wrong guy that is Team Skeptic not Team Septic or whatever language you are trying to write. Sorry if English is not your first, but whatever you rambled on about did not make the utmost sense
@Anti-Tik Tok Coalition knowing team sceptic, it will be the first. He is a conspiracy debunker. Highly recommended of you are in to this. And funny. Ding....
@@claytongarred3870 Sceptic was the original correct spelling of skeptic, know-it-all 😂
This is like the best teaching video on viruses I have found yet! I’m in undergraduate level virology so there are some details missing but the majority is all I need for understanding and is so helpful thank you!
Learned more in this one video than 12 years in school.
Dude, You are a legend, I study microbiology and it is hard but with you, it's easy I have only one thing to say just keep up the good work ♥️
Just 1 virus particle can cause an infection? That's brutal.
I'm glad they're relatively harmless.
Relative harmless until SARS asks you to hold it's beer.
@@magnuscritikaleak5045 *gives a corona”
A virus does NOT want to kill it's host.
@Arthur Morgan II No it is the virus
@@nordnow A virus that kills too quickly makes itself extinct.
Ever wonder what would happen if a cells own RNA got absorbed in a viral onvulope
Cells have DNA.
Well.......
I guess there must be some mechanism by which a virus recogonizes its own genetic material.
If u talk about bacteriophages, during the LYSOGENIC cycle, it sometimes happens that a part of the bacterial genome gets into the genome of the new virions and gets transmitted to other bacteria.
(addressed to Professor Dave, though not a direct reply so Ozzy&Drix2001 can see it) Don't cells always have some transient mRNA?
yes of course, but their genetic material is DNA
No
Thanks for another informative and organized video!
Anybody watching this video with a cold right now? 😩
No more with herbal remedies

I wish people would do do their research and take viruses seriously. Instead of dismissing the CDC and medical community more people should be willing to learn that viruses are not to be toyed with. Im here after learning of the polio virus and its effects. Whether it polio, rhino, corona, flu, ebola or any other virus listen to the science for your health and those around you.
I think we will eventually, at some point in the future, figure out away to create a vaccine for the Rhinovirus. Maybe with some type of future tech that doesn't currently exist. Anything is possible in the future, we just don't know what will happen. I am trying to be positive.
May I just say you are an absolutely amazing human being for sitting through that “discussion” with Jesse Peterson
I figured out the main risk factor for COVID19. It's blood pressure. Areas most affected. Lungs smelling part of nose heart even feet. Have most ACE receptors.
Men often have higher blood pressure race also a Biological factore .
Lowering blood pressure might reduce ACE genes
Did u publish your findings on pubmed?
@@xiaozhang7103 I'll see
@@OzzyDrixClay Check before you post.
Water lowers blood pressure.
Which of the following viruses usually causes a mild rash in children, but is considered an important tratogen:
A. Rubella v.
B. Polio V
C. Rhino V
D. Influenza V .
Rhinovirus duh
If I went to live in the woods all by myself, and never have contact with another human (grow my own food, etc.), then I would never have a cold?
Maybe, but you would be very lonely and probably lose your mind.
then you will get diseases from natural causes
skun, as long as you had ample sunlight you would never get sick.
@@MainStreetElectricalParade prove it. After a lifetime of chronic lung and bowel issues (inflammation), and no solutions from specialist$$, I have dropped all medications and have not seen a specialist nor been hospitalised for 11 yrs now :)
Nym Net that's great , so may I ask what lifestyle changes you have made to become drug free ? Best of health to you 😀
Do you have a video that explains why some infected people are asymptomatic, while others are not?
It's probably because of the viral load and how good your immune is
But I am not a scientist
I’ve always wondered the same
In my case i believe i don't get anymore colds and flu,but very rarely,because of my allergies.As a child and young man,i use to be sick all the time,specially in the winter,but around 35 years of age something triggered allergy to all forms of pollen,and since then i don't catch anymore colds,it's like i became immune to them.
Nice explanation. The more i learn about viruses, the more intrigueing they become.
This guy deserves some kind of award for what he does!
Thanks again Dave!
Why does science have to be so complicated and confusing?? 🤣 this video is bringing me back to my Grade 11 Biology class, which sucked 😳 I appreciate the info and I’m so grateful we have people like you who understand this stuff, cause I do NOT 😂
I wish science was simple. I’m in so biology right now, and we’re going over the stuff we learned in regular biology,except we’re being told stuff like “remember that cellular process that you got confused by in biology? That was an extremely simplified description of the actual process, time to learn it for real.” It sucks, I’m so confused all the time, but it’s also fun to learn new things
Great videos professor Dave! Question. You mentioned that non enveloped viruses are particularly immune to detergents. Rhinoviruses are non enveloped, so why does washing hands make a difference in its control? I know you mentioned that rhinoviruses are less hardy than their other picornavirus brethren, and you said that low pH and temperature exceeding 33C are enough to destroy them, but the hand-washing environment of soap and water isn't usually that inclement. I'd be curious to know the chemical mechanism through which washing hands etc helps?
Still no answer. Oof.
Maybe thats why they said it kills 99% of germs. Besides you are still washing the virus off your hands. And soap helps this cause it makes water wetter.
@@12outland12 soap makes water... wetter...? 🤔
@@zcecp49 yeah it technically does. Soap breaks up the surface tension of water. This causes the water to spread out and more easily cover the surface of whatever you are getting wet. Think about it, soap itself is not slippery. But when you add water, the soap prevents the water from sticking to itself and instead sticks to your hands making them wetter. Seriously google it, it is true.
Washing your hands work because of the mechanical action. Soap and water removes oils on your skin which the virus may stick to, which whilst it doesn’t kill the virus, flushes it away from your hands
Finally a video of Rhinobirus
🅱️irus
@@xiaozhang7103 hahahaha
IIRC, some decades ago the US Army conducted a hand washing experiment to see if the incidence of cold-type infections could be reduced by increasing the frequency of hand-washing.
2 groups of several thousand soldiers either washed as usual, or washed at prescribed times in addition to their normal routine.
The answer was yes.
I like the hair-cut Dave, first chance to visit the barber since quarantine was enacted? :)
Great information Professor Dave! Thanks so much!
I currently have Rhinovirus and it is so bad i had a sore throat a bad cough runny nose and tiredness :(
It sucks having a rhinovirus
On one hand we know how viruses work. Yet OTOH it seems pretty crazy how they work.
hi prof D. I have a very important question... iv had a bunch of theologians claim that mountains act as pegs that hold the earths crust firm.. as far as i know that is NOT correct.. buut they throw in big words like isostasy and blah blah.. what is your take on the subject of mountains having a function such as acting as nails ,for the ground..
I remember the 1960s when you had the common cold science lab where you can go and isolate and play chest and what have you. They were doing studies on the common cold it's a shame they closed it down because you could have had a vaccine by now for most common colds
Wow, well done professor
U got my like as soon as I saw the intro with the song 😭😭
Clark, that there is an RV... But, don't you go falling in love with it now, because, we're taking it with us when we leave here next month.
Finally back on track with all your videos professor. Shock with your new hairstyle 😅😅😅 but I love it.
Thank you very much
Me watching this as I’m blowing my nose every 10 seconds
Nice to know!
if the common cold can't withstand 33c+ how can they survive in the body which at the lowest should be 36c?, i do know we get a fever to geat up the body and fight it, but my question still stands
I'm not Dave, but...
1. Because of their exposure to outside air, the tissues of the upper respiratory tract are often significantly below core body temperature.
2. The core body temperature threshold for hypothermia is typically around 35 °C.
3. While in the body, rhinovirus is constantly regenerated. The virions don't have to "survive" for long to maintain the infection.
I have been on dialysis since 2014 and this year was the first time since I started that I got a cold. Or at least I think it was a cold. May have been that which shall not be named.
I think 3 or 4 coronaviruses are responsible for cold-type infections.
Please make getting a transplant your immediate priority (if it isn't already). Long term dialysis has many serious risks that patients in the USA are not really properly informed about. So I heard: czcams.com/video/yw_nqzVfxFQ/video.html
Please try high-dose vitamin D. Look it up.

@@DickHolman come and get me! lol
Would looove to talk to this guy about current ongoings
Is "tutorial" the right word for these videos? Typically that word is used when giving instruction, this is education, offering information--not instruction... I would go as far as to call him a "private tutor" (as its his own project), but even still, does tutorial really match??
Wikipedia: A tutorial is a method of transferring knowledge and may be used as a part of a learning process.
@@ProfessorDaveExplains thanks for the reply. I think Merriam-Webster does you even more justice:
1: a paper, book, film, or computer program that provides practical information about a specific subject
2: a class conducted by a tutor for one student or a small number of students
There’s nothing common about how a cold feels. It’s easily the worst feeling in the world.
I get cold almost every month. I'm fucking sick of it.
Hey Dave. Think you could do a series on prion diseases sometime after you’ve wrapped up this one? 🙂
yes i definitely will do one on prions after the survey of viruses!
Professor Dave Explains Thank you!
@@ProfessorDaveExplains 2 years later you still haven't made a video about them, im waiting
if 1 kg water at stp occupies 1000cc, then if i extract h2 and o2 from 1 kg water and store h2 and o2 in liquid state, which will occupy more volume? 1 kg water or sum of two liquids?
Liquid H2 would be 1.5 L on its own.
Thanks for plain, simple info without agenda mate!
You have helped me cause I have RV right now
What’s crazy is how similar viruses are to plasmids
nice topic Prof.
Just for this vid explaining everything Imma Subscribe
I’m not gonna lie i get it every winter one year it developed into laryngitis 2016 and one year developed to mild bronchitis 2018 and none of them were nice the 2018 one was worse as the cough I had lasted for two months after I initially had it. At least it was just common cold for this year and 2019
Fr my common colds last from 1-4 days and i get them once in spring and winter
Time to start my school project on rhinovirus😅
Hope you did great!
woah professor dave
Thank you for offering us some education :)
Is it correct that the amount of viruses per mL is 100 to 1000 in peak-times?
I mean if one infected cell can lead to 100.000 viruses you would expect more, wouldn't you? What am I getting wrong here?
Greetings from Germany :)
That intro! YES! amazing lol
Professor, i need ur resources to help me do my researchs in university
How did u get a hair cut?
Watching this during having a cold...
If rhinoviruses can bind to ICAM-1, then can they cause internal bleeding?
Why would these virions release histamine that iirc helps the immune system deal with them?
If I heard right, it's not virions but infected cells.
@@jika327 yeah i think that is correct. I think also (could be incorrect) cells can kill themselves aswell when they become infected, but, as I understand the virus takes over the cell and is unable to do so.
That's why virology is really important in the study of cancer because it would be great if cancerous cells killed themselves
Nice cut prof. XD
I am suffering from what you say all about that was called rhinoviruses what should i do sir can you help me sir please what treatment is?
Epic intro bro
Sir can you explain how RNA got negative and positive signs,I mean whats the logic behind this
I dunno what you mean.
@@ProfessorDaveExplains i mean why it is called positive or negative RNA to be more particular on what basis we call them
Oh, positive sense means ready to be translated, negative means complementary to the transcript so negative sense must be converted to positive prior to translation.
@@ProfessorDaveExplains thank u so much that you responded , you are such a down to earth person cuz' I didn't expect u to be replying. From one of your biggest fan
You chopped off all your hair! You look great either way
I was going to say the same exact same thing, dang !
Sir I have mailed you a doubt of mine pls help me in that
I'm 16 years old, male
I very offen get common cold averagely after every 5 days
It goes by its own without medications
I'm noticing it since from last 8 months
I'm from india
Is it directly or indirectly related to my immunity
Please tell...
Common cold ends on its own
Rhinovirus - ya think is funny but it snot.
Keep your day job.
Thanks for the informative video during boring quarantine.
I have a question about corona virus: In Holland the contamination rate should be around 3% by now. Shouldnt that be much higher after a few Months based on logic? If it is really 3% by now, would it have spread over the world like it Did? I think the contamination rate must be much higher by now which would declare a lot of phenonema, but not recoqnized by authority...though hardly tested, they keep saying 3%..
Yes
I don’t feel COLD.
Colds suck
Nice Haircut
Looking cool sir😎😎😎😊👌
Maybee the cold is just like lip Herpes, it stays in your body forever and activates when u have low immunity?
What could be the cause of catching a cold every month ?
For the last 6 years after starting work at a new company this has been happening and not just to me.
maybe a weak immune system

So Rhinovirus is just a common cold?
Rhinovirus is a typically innocuous zoonotic virus which affects the cells of the upper respiratory tract in man yielding = _"a Cold."_ A Cold therefore is just an appellation indicating a mild upper respiratory infection caused by = numerous viruses - of which the Rhinovirus is one.
There are loads of viruses capable of infecting your respiratory tract and thus _"a Cold"_ has no single cause - which is part of reason you do not see a vaccine against Colds. Unlike say Measles which is caused by a specific virus - Colds are not and are as indicated typically mild and self-resolving. So "symptomatic treatment" is all that is required.
The earth is a triangle though
First!
I think if your using someone elses toothbruch the handle is the least of your worries
When I become president I'm doing a lock down over the common cold. Let's stop the Spread!! I absolutely hate having a cold.
my brother and his family thinks he has this…will be survive?
Since my daughter began kindergarten she and we got the cold almost every month this season.

What is the difference between the Common cold and Covid 19?
Rhinovirus and Coronavirus are totally different families of viruses.
@@ProfessorDaveExplains 🙄 They the same.
@@Ryan-mf2rg Um, no. Read my previous comment with your brain turned on.
_"A Cold"_ is an appellation for = an upper respiratory infection of a typically innocuous nature which is self-resolving. Covid on the other hand can generate a more severe infection which can not only affect your respiratory tract = but in susceptible individuals it adversely impacts other systems to possibly lead to organ failure etc..
Moral: loads of viruses enter the body through your respiratory tract since viral infections can result in "virion" dissemination via coughing/exhaling and we are constantly breathing in air from our environment. So the cells of the upper respiratory tract are typically the first to encounter any airborne pathogen you might happen to inhale.
As to what follows depends upon the capacity of the virus in question as to which cells it can infect - thus triggering an inflammatory/immunological reaction by the body. The greater that reaction resulting in cellular/metabolic disruption = the more severe your symptomatology will be.
Viruses capable of infecting lots of difference cell types throughout your body can result in a severe infection impacting multiple systems. Conversely viruses which only infect certain areas and which do not cause massive "viral amplification" tend to create "mild illness" - such as a Cold.
runny nose cough and nasal congestion!!!!!!!!!!!!!!!!!!

i have the cold while watching this what a coincidence
I always get the cold, lol.
