While ‘the flu’ has become a slang term that refers to almost any ailment where you don’t feel quite right, true influenza refers to a handful of specific viruses that invade the respiratory lining, evade the immune system, and mutate at a rate that even the world’s most brilliant doctors, scientists, and health organizations struggle to keep up with.
To learn more about what influenza is exactly, Seeker sat down with Dr. David Morens, an epidemiologist, virologist, and historian at the National Institutes of Health. Dr. Morens is also an officer at the United States Public Health Service.
The flu’s symptoms are well-known: coughing, fever, headache, muscle aches, fatigue, and just general malaise, a.k.a. just feeling generally really bad. And while these symptoms could be a sign of many other illnesses that are similar to the flu, there is only one True Flu and it is tough to nail down the countless variations that exist.
So, we’ve sorted the different types of influenza into four categories: A, B, C, and D.
Find out more about the different categories of influenza, the complexities of the flu, the importance of a yearly flu shot, and more on this episode of SICK.

Flu Season Is Here and Cases Are on the Rise

"About a month ago, the World Health Organization (WHO) announced that this year’s flu vaccine might not be as effective as we’d hoped. The four strains it was designed to target didn’t match the strains circulating in the Southern Hemisphere: influenza A (H3N2) and influenza B (Victoria). As expected, those two strains that hit the Southern Hemisphere are now striking the United States - in Louisiana, Alabama, Georgia, Mississippi, South Carolina, Texas, and Puerto Rico."
Key Facts About Seasonal Flu Vaccine
www.cdc.gov/flu/prevent/keyfa...
"Influenza is a potentially serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. An annual seasonal flu vaccine is the best way to help protect against flu. Vaccination has been shown to have many benefits including reducing the risk of flu illnesses, hospitalizations and even the risk of flu-related death in children."
What you should avoid eating and drinking when you have the flu
www.insider.com/what-not-to-e...
"You don't want your body to spend its limited energy on digestion; you want it to be working on fighting the virus. So avoid fatty foods, especially if it's the unhealthy type of fat like what you'll find in pizza, burgers, fries, and other fast food."

Is it true that influenza came from animal farming practices like many other diseases have?
Seeker what is the cartoon on 4:00 its been really bothering me that i have forgot it!
Flu comes from china
Shit shit
Me: I guess I'm healthy now. The Flu is over
Flu: I'LL BE BACK !
comes back, drives you over with a police car. yes. thats what it feels like.
this year and last year there was a 30% chance of them working
I have been without flu for a long time, but my child got flu though I smeaared her teeth with black seed/habba sawda then she had no flu anymore...
dun dun dun - dun-dun! Dun dun dun - dun-dun!
@Will Pack She coughs and has alot of snot coming from her nose... You can easily tell if she has the flu, also reaction to me and so on...
It's like call of duty, comes out every year worse and worse.
lol
Except for this year
Graphics get better and better, gameplay is just eh
BS estimates designed to get more and more people getting the vaccine.
0:40 he's definitely under the influence
Can we all appreciate the guy they’re interviewing? Damn he’s got everything 😂
👏🏻👏🏻👏🏻
He also got a Flue when he speak 😂
He also got a Flue when he speak 😂
Me: Glad I made it through flu season healthy!
Coronavirus: 💀
Because it's *antivirus update*
LOL 😂
Out of many of my customers three got the flu shot and ended up in the ER due to a reaction. This was a month ago approx. docs told them an allergic reaction to the shot. I said: did you ask from what? None of them asked from what. I thought that was just crazy to me.
Agreed 💯 coincidence NOT.
“Is the flu over?”
*Flu:* well yes but actually no
Yo myself!
Naga Praneeth Chukka Ayyyyyyyyyyyyy!!!!
Ayyyyyy ;)
Ayyyyyyyyy!!!
@@abdlhmdx ayyyeeeee lmao XD
You never answered the question why the flu is yearly....
because big money
I'm guessing because it technically isn't, just people are more vulnerable in the winter due to the strong constant contrast between outdoors and indoors and long periods indoors with other people, that is how they explain the cold being more common in the winter at least, and neither viruses disappear completely over the summer.
Pharma!
flu is around all year but it takes off big time in the winter because people congregate indoors and the cold weather drops the humidity and dries people's sinuses out which makes them more susceptible.
I’m confused even more like wyf
I’m pro vaccination(because I’m not mentally challenged), but I stopped getting my flu shot ~10 years after having a terrible flu two times in one year after getting the flu shot. I have not had any major flu symptoms since then. I’m not conspiring on anything, but the flu shot is one thing I genuinely feel like is pushed very hard, with little results proving it works as advertised(opinion).
It seems like you look at it as a cure-all. Because of the biological complexity of the virus you might still get it. Last year I got it even though I had my flu shot--it's no guarantee.
Just look at the immunization rates for nurses around the world. I doubt you will find many nurses that are antivaxx but over half refuse to get the flu shot even if they can get it for free.
@@Jake12220 Well I can speak on that because I'm not a nurse or a healthcare professional, but I do consider myself an informed consumer. That's interesting to hear you say. I'll look into it. Either way, it's not a cure-all.
@@ACrownofFlowers it's definitely not a cure all and l am a nurse, my mother is a nurse and l work with many nurses and doctors as well. I can only speak for nurses rather than doctors though as there is far more data available, in part because of a major court case in America by one of their nursing unions defending the right not to get the flu shot, which they won.
There are many issues around the flu shot, mainly that it's pushed to the public as being a vaccine on the same lines as other vaccines, but unlike other vaccines the testing and validation phases other vaccines must go though are skipped completely with the flu vaccine. Due to the rate influenza mutates it's simply not possible to test the vaccine properly so it's tested in the wild by being given to the public and results measured by the amount of reports issued by doctors in regards to side effects. Unfortunately this is nowhere near as reliable as clinical testing as doctors won't even know if people get mild side effects, thus reports of side effects tend to be limited to severe cases like those experienced in Australia a few years ago where multiple children died and that years vaccine ended up being banned for use in children under a certain age. One of the biggest issues with the flu vaccine and one of the primary reasons many health professionals don't want it is that even if everyone got it every year it wouldn't prevent the spread of the disease. Even when they guess the right strains to put in the vaccine the effectiveness is never even close enough to generate a herd immunity and people who have been immunised, even when effective are still just as likely to transmit the disease to others(even if person b is immune they can still transmit it between persons a and c). Indeed people who have been immunised are thought more likely to spread the disease as the psychological effect of being immunised means they are likely to be less cautious about exposure to the disease so in a clinical setting not being immunised and thus more concerned about exposure leads to better use of protective equipment like gloves and masks along with more care in hand washing use of hand sanitizer.
It's funny how sometimes the problem with something is not entirely because of the thing itself, but rather the unexpected effects its causes. Same with mammograms leading to higher rates of death from breast cancer, it's not a fault of the test, but the behaviour it causes in the people getting the test.
@@Jake12220 I agree with that but isn't their herd immunity anyway? and I think I did hear about that one nurses union case.
Lol I haven’t gotten a flu shot in like 6 years and I’ve never gotten the flu...
No I’m not an anti vaxer, I’m just lazy af
me to :D ... if everyone around me have it I don't need it. :D
Stay lazy friend...stay lazy
Shit, I forgot I must fear to die. How could I. Even with all the intel saying a biologic war will happen... dooo, I will continue to make sure I'm a vegetable, maybe I get along.
I would get it if I could afford it. But yeah it’s not like other vaccines where one will take care of it
maybe you're Superman, have you tried to use your powers?
Earlier part of video: the virus mutates so quickly a flu shot becomes worthless
End of video: don't walk but run to go get your flu shot
🤔🤨
Exactly what I said lol. We can’t cure or vaccinate against it.... but trust the government with this mystery juice we’re gonna shoot into u! 😘
@@TheeMilesMonk exactly
Exactly
Nope
You're misquoting he said the virus mutates so quickly a flu shot _sometimes_ becomes worthless.
Loved the video. Just wished the audio was a bit louder so I can hear it while I am listening to it on the trian with my headphones on.
aww that guy is so cute
That was probably the best way to ever cut the cake
Speaking of the Flu, I think I had it last week. It took me almost a week to recover.
By the time you got recovered, you need a new flu shot.
That was Covid lol
"This video is so we'll at explaining the flu. Props to the seeker channel for making this video BRILLIANT"
Watching this while suffering from moderate flu. Nice.
Because they need to sell medication to treat its symptoms.... I bet it gets released every year seems weird it comes back every time of year...
Flu shot is free in my country. It should be free everywhere :(
Don't be dumb. There is nothing special about a year. They could probably make a new vaccine every 6 months, or every 18 months etc. It's just a tradeoff between various logistical factors and the fact that making it once a year concides with seasonality and makes it simpler for regular people to keep track of.
@@Robin_Coffins which country are you from?
Watch those chemtrails above in the sky.
Funny, i just thought about this the other day. Thanks for the video.
David morens is life goals
1 minute in, still explaining what the flu is. i didn't come here to learn for the millionth time what the flu is :-P
We definitely need ai working on this, we have plenty of data to feed it and the problem seems too difficult for humans to deal with quickly enough to stop the disease.
4:00 what programme was that??
Why is it every time I get a flu shot within 24 hours I get very sick, but when I don't get a flu shot, I never get more than the mildest case of the flu, if I get sick at all?
Because vaccines contain mild amount of virus/viruses that your body will then fight against in order to strengthen your immune system
He talked about what a giant guess the flu vaccine was. Then tells us to run and get it?
it's still making you more resistant to thousands of types of flu. and it's possible a southern strain will come up north and spread too, but they're still pretty good at predicting which strains you're most likely to come across in a year's time. it may not be 100% effective against all flu viruses, but it still reduces the chance you'll catch many other strains in your surroundings, and that removes you as a vector for spreading it to thousands of other people, so yeah, definitely good to get it anyway. they're often free at the pharmacy
And even if it doesn't prevent you from catching the flu, it can still help you fight off the virus a little more quickly/easily. And every year they have a new vaccine, and even though it's a kind of a crap shoot, some years it is really quite effective.
tommy aronson The flu mutates on its own. The flu shot does not make the virus mutate. It’s prone to mutations because of how its RNA works, which was described in the video.
So you're saying if something is only 80% likely to be effective instead of 100% then it's utterly worthless? Strange all or nothing logic.
I haven't had a flu shot since I was a kid and haven't gotten sick in years even when im around someone that's sick
Bestest channel on RUclips
That doesn't answer the fundamentals question as to where the virus keep coming back every year. If the virus cannot survive outside host body. If it all die by certain season, where does it come from after being gone for awhile?
zoonotic animals (water birds mainly) are a constant reservoir, also the other hemisphere as explained. It doesn't die everywhere at once, it moves like a wave.
@@Tinky1rs Hmm given our efforts with Covid... we should expect less infections this season right???
@@collian in theory, yes. Covid has been teaching people the value of washing yo hands and not touching your face.
Anyone else feel like they should stop breathing when it showed influenza entering the mouth?
I've never gotten a flu shot in my life and I very rarely get the flu and if I do I recover within days. I'm not anti-vac but I see no logistical benefit to it at the same time.
Herd immunity for one. If you don't care if you get it you aren't caring about spreading it to others.
It's ok if you lived totally isolated to other people. I mean real "complete, total isolation". But even so, you still have chance of getting bird-flu.
Remember...even if you don't feel anything...you can be contagious
@Frank Wiley it's not like the "toxins" are gonna like kill you or something, when you receive a flu shot it sends in weakened and/or dead flu viruses so your body can fight and train thus making you feel somewhat sick
@Frank Wiley What "research" are you referring to and where did you got those research from.
What are exactly the Toxins you are referring to and how did 15 years of experience on lets say actual research lead you to this conclusion.
I'm now worried about tbjzl
Not had any flu for 20 years now
There couldn’t have been a more convenient time for this video to uploaded.... I’m ill lol.
At this rate, I'd give expecting mothers an Inhalation of Type C with lots of the other key proteins/Antigens a day later.
Like . Days before thd due date.
and the babies get the Anti-Bodies when nursing.
And Boys entering Puberty.
For epigenetic reasons.
I used to get 'the flu' about twice every year until a stupid accident , after that I have never gotten 'the flu' again.
What happened?
IfYouMeetAWolf I got in a stupid car accident then I started becoming more health conscious , I read about the health benefits of raw garlic , put one in my mouth every time I felt a cold/sneeze come up , chewed it up when it started to hurt my mouth , and I never got the cold ever again. It's kept a secret because the big companies can't make billions of dollars off a simple thing like garlic.
@@terryi8892 That's an old housewifes tip, and it probably works because garlic can kill any sign of bacteria.
I'm just wondering if perhaps it could also be because of a much healthier lifestyle (less sugar creating less inflammation etc) that's the root cause, while the garlic is the gate keeper?
Flu: *THIS ISNT THE LAST YOULL SEE OF ME!!!*
Dam It’s like your Getting a Zombie Virus at 0:39-0:40 While your Dancing too!!!! 😂🗣🧠👃
i havent had a flu in the last 5 years? what does it mean?
I have not heard one person not get the flew after a flew shot.
Did they grow wings?
never had a flue shot nor had the flu for over 20 years.. now worried how this may be a super bug to me now.

Thanks for releasing it every year and making it last even longer?
Somehow i feel that the question wasnt really answered ...
Mutations. The end.
@@DARKSHATOW and antivaxxers
What do you want to know it was pretty informative
@@magentalizard1250answer to everyone who don't think they need it right
Question was pretty clear to me. It also was not answered. Creepy part in video (When you touch your nose or (breathe contaminated air) after coming in contact with the virus. Why is the air contaminated? How does 1 happen to just come in contact with it?
Flu is biggest villen during exam periods😂
I had influence 3 week ago, now i m ok.
Got the flu whilst watching this 😂🤦♂️
oh yeah yeah you’re not funny

@@RorytheRoman sub to my channel
Same
I normally got the flu every year, but now i dont get it for over 5 years. Is that normal?
I got sick 2 weeks ago and it lasted a week, then I got sick again right after, WTF! I got so weak the second time
I thought he was going to sneeze ! @ 3:12
"The flu shot is likely worthless but run and go get one."
tommy aronson I mean for me it’s free
@K!ngS!ze the spread of the flu has nothing to do with being clean, lol. Many diseases are the result of unclean environments...chicken pox, cow pox, bubonic plague, swine flu, bird flu...they are all caused by disgusting conditions and coralling animals in filthy small enclosures. And I never had the flu either until I got it and almost died. I make damn sure I get a flu shot every year now. Also if you have a family member with a serious disease (like cancer), you are putting them at risk if you go around them without being vaccinated against the flu. Believe me, you will deeply regret not getting your flu shot when you contact the flu. It is just a matter of time. It may be this year or the next, or 5 years from now, but it will catch up to you...and you will feel like you're going to die when it does. Thank God I have my flu shot and so do all my close family members.
@K!ngS!ze There is group immunization which helps people like you who don't get the shot. The shot is basically the flu, but with all the viruses dead, so when it gets in your blood, your white cells see it as a foreign entity and attack it. With it being in your blood, the white blood cells can get to it really easily and allow it to learn how to fight it. Then, when it detects the virus in your lungs, it can actually fight it, instead of trying to figure out what to do.
the flu virus doesn't get stronger with its dead partners. The nature of the virus is what causes it to get stronger.
@tommy aronson Much like your grammar.
Really don't understand why it helps to take a flu shot that is a shot in the dark. It's just gonna be mutated already.
I survived the Hong Kong flu, nasty thing to be sure!
So, are influenza living creatures? Meaning, do they consciously or unconsciously evolve or mutate? Do they live with a purpose?
That thumbnail looks sick
But... why are we much more prone to get an influenza if it is cold? In summer we are basically out of danger. I have newer found a llegar explanation for that.
Travel of persons/groups of people - around/through other countries/continents could be a factor.
We want season 3…
So why does the flu come back every year???
They spray it in the air
certaintly the stakes is "rampping" up 4:47
sooo.... why does it come back every year?
Anti virus updates
Cause idiots who go out and cough on everything.
Right about one thing don’t walk run and the daily and you won’t get sick! That’s how awesome the human body is!
I didn't get it.. why does ot come back every year??
I wanted to know why the flu comes back every year. I watched the video and I didn't see them answer that question. Did I miss it? Why does it come back every year, why don't people have the flu all months out of the year?
and I know you can get the flu at any month, I am meaning the flu ramps up and they call it the "flu season"
Is it me or When I get a Shot For the Flu I still get Sick . But Without the Flu Shot I don’t Get Sick. Bc I didn’t Get A Flu shot like in 4 or 5 Years Now and Never Got Sick when Not Take a Flu Shot But When I do I get sick like A Month later ???
So, is it just always around then? You don't answer the question in the title.
Why are there flu seasons? Does it go away and come back? Thanks for nothing.
Bro, this video dropped like a month before Corona broke out in China 😲
Huh...??
He actually said zillions😂

Why didn't I get it for the last decade?
Why some viruses dont cross contaminate between species?
I have never got the flu, I've never got a flu shot.
But I get a cold every 2 months or so
I teach in public schools. I get the flu twice a year even with a flu shot. Kicks my ass the older I get.
Did he say “ Don’t walk, run and get your flu shot
Where is Trace?
i always had lots of flu when i was small, and now, I don't have almost no symptoms of it, for example, i don't get fevers, coughing, muscle aches or anything like that. the only thing that happens is nose clogging :)
It's just like a game. It's making yearly balance changes lol.
So the answer to "Why does the flu come back every year?" is, there is no answer?
Why can’t the immune system just not fight it given that flu symptoms are the immune system reacting to this foreign thing. What’s the worst that would happen if your body just didn’t attack it?
The last time i got flu is 5-6 years ago
Does that officer have a shaving profile?
I go to smoke a Newport 100 and drinking my coffee before i go to work I need to quit but I got my flu shot 😷
What he say at the end? "don't walk or run, and get your flu shot"?
Jay Kal I thought he said “Don’t walk, and RUN to get your flu shot!”
This is some propaganda shit. I don’t know if I like Seeker anymore because of stuff like this.

Doesn't the Flu originate from India or Southeast Asia?
Not really. You might be thinking of the black plague, but even that's debatable these days.
The flu is assessed in various parts of the world each year in order to predict what strains should be put in the next vaccine, but it basically just goes round and round over and over again.
