Dave the reason for the name "Spanish Flu" is because Spain finally confirmed the flu when other nations (USA, France, etc) would not. Spain was a neutral country during World War 1.

There is a reason the average term exists, average intelligence people continually watch those minuscule and nigh irrelevant topics while rarely focusing on important informative things like these. True above average people in intelligence are capable of reaching out and gaining information. To get knowledge you must eliminate or at least suppress obstacles masking information. Those videos gain views and pop up in your feed to mask informative videos like these

Love your videos Dave! Very informative and inspirational to take general scientific knowledge to the next level.

Your vids are SO clear and educational. Thanks again Dave

What causes the virus to mutate?

@ProfessorDaveExplains

Mutations are the result of mutagens and chance replicative errors, but they are selected for by natural selection, same as with all other biological systems.

Great work, Professor Dave. Started following your channel about 6 months ago and haven't missed a new post yet. It's been fun going back to some of your older stuff, as well as checking out your earlier music career. The montage of the various Mario Bros. songs on the piano (for the kids?) was a lot of fun to watch.

It's a great video, but I'd like to point out that there's a little mistake in the viral structure: what you called "capsid" is actually a protein matrix (the inner layer of the envelope). Influenza A has a nucleocapsid, thus the "capsid" arrow should point to the proteins surrounding the RNA.

I already knew alot of this but thanks for better solidifying my understanding ✌✌

Thank you dave currently studying nursing and this has helped me a lot .

I had the influenza A couple weeks ago. I thought i was going to die for 3 days i felt horrible mainly at night. Thank god i git better but u still have chest pain an get a cough that makes mucus with little coffee grains. I also quit smoking cigarettes when i git sick so im sure it might be my lungs getting clean.

Hi Professor Dave Explains, when they make flu vaccines, what part or parts of the flu virus(es) specifically are they putting into the vaccines? I keep coming hearing they are adding strains of what they figure will show up most, but I don't know precisely what is meant by strains. I would assume this means that they are putting small amounts of the whole of a virus molecule, comprising the protein spikes, sphere and RNA within. Is that what is meant by a strain? Thank you.

Please tell me how the pneumonia related to influenza i mean i am confuse in the segment transmission of influenza

Think of your immune system in terms of = _"stimulus -----> reaction."_ In other words your immune system reacts to stimuli and it throws its' focus upon = the strongest stimulus at the time. This means the more severe the infection the more your immune system focuses upon fighting off that infection. Yet within you are loads of microorganisms - some good and some bad. The bad ones are usually kept in check by your immune system + by the good ones who are waging a constant war against each other. As an example. Your intestines contain E-Coli - which is bad being pathogenic. Yet your intestines are also full of good bacteria which helps you to digest your food. So they along with your immune system = keep the E-Coli in check - usually. If the balance is broken and E-Coli replicate out of your control you can end up sick. Moral: for some if they catch the Flu it might tax their immune system to the point that other _"opportunistic"_ organisms get a foothold because of above. Your immune system being focused solely upon fighting off Influenza allows them to get a foothold. When this occurs it is considered as _"secondary infection"_ as the video alludes. Most folks actually die - not from the Influenza per se - but from secondary infections. Fighting off Influenza weakened them to the point that pathogenic organisms - either already within them or for which they were subsequently exposed while sick with the Flu are able to replicate out of control. As Influenza affects the respiratory system + pneumonias are respiratory infections = pneumonia is a possible deadly side effect of the Flu - either viral or bacterial.

So with other words, the Plague doctors was on the right track but did not identify the right way of the spread. A mask that cover the whole face, stuffed with things that suck up moist, then cover body with a hoodie that cover the head and neck area too, then gloves and boots, that almost sounds how I want to dress when I go to the store. Like a face mask that cover mouth and nose and have filters I can replace, some swim goggles (behind some shades), and latex gloves; and then when I come home use something that almost is like the Miasma theory by washing hands 30 to 40 seconds two times in soap that make my hands smell like roses and lavendel.

Who’s here because they have the flu 🥲

I am 85 years old. I tested negative at the Dr. office for the flu. But specimen sent to lab indicated Influenza A. Can’t recall ever being this sick. Most symptoms are almost gone, but general weakness keeps me close to the couch. I did get the flu vaccine in early November. I’ve also had all Covid shots to date. So my question is..did the vaccine protect me at all? And how did I get a negative result at Dr. office but positive from the lab? Please clarify my confusion. Thx.

Think _"a rich man and his guards."_ In response to infectious microorganisms etc. your immune system reacts in several ways. One of the ways is by producing _"antibodies."_ Antibodies are proteins which mirror segments of other proteins/peptides such as make up the surface of an infectious pathogen. These structures on the viral capsid are termed as = _"antigens."_ So depending upon the severity of the exposure your body generates a corresponding number of IgG specific antibodies. These upon encountering the virus in the bloodstream attach to those antigen receptors on the surface of the virus _"inactivating"_ it - meaning it can not attach to your cells to infect them and replicate itself. Yet as the video speaks to some viruses - especially _"zoonotic ones"_ - mutate as they spread. Enough mutation of those antigen structures and antibodies generated against previous versions might no longer match up well and neutralization will not occur. This is what the video referred to as _"antigenic drift."_ Moral: Flu vaccines - and vaccines in general - _"pre-stimulate"_ your immune system to produce antibodies. Yet annual Flu vaccines must choose early in the year what strains they will contain based upon analysis of spread of variants of Influenza in the world. It takes months to produce enough vaccine for a coming Flu season = months during which those circulating strains might alter themselves a bit. Thus by the time Flu season comes around it is possible the strains in the vaccine have changed a bit in the interim. Also sometimes a virus mutates in a manner which allows it to generate a higher _"viral load"_ than before - like Covid. More viruses mean you need more antibodies to neutralize - or "guards for our rich man." This is the concept behind booster shots which stimulate your immune system to generate even more antibodies to keep your levels up. Then if exposed you hopefully will not become sick - but even if you do you should end up less ill than you might otherwise be if unvaccinated. Because you will already have antibodies on board your viral load should be less which means you develop milder symptoms. p.s. - _"quickie"_ tests in a doctor's office or whatever are just for general screening. They can give the physician additional verification for what they suspect based upon your symptomatology. Serological assay (lab tests) are always the most accurate. They however obviously take longer and are more expensive. A doctor will already based upon your symptoms have an idea of what they are looking at. They order testing = to confirm that. Try not to get hung up on "tests" - quickie or assay. They are in most cases a general screening tool is all.

to be more accurate "antibiotics only work on bacteria, not viruses"

I have a possibly stupid question. Are viruses actual living animals? Because they seem to function in a way that seems more like a machine than a living organism.

@Tornadopelt

They're not considered alive, even though they can be killed. Viruses are in a sort of "grey" area between clearly not alive and clearly alive, but they cannot reproduce on their own and they don't maintain internal homeostasis, two of the most important requirements for something to be alive.

By talking about the flu and not talking about coronavirus he leaves the politics that have been built up around it out of the conversation.

Hey, Dave, what is the difference between the three classes of the flu? (Influenza A,B,C) I've tried finding difference sources but some are a little confusing in their explinations.

@HeyImLucious

Difference is: all 3 cause the flu. Type-A can infect a wide variety of animal hosts. Type-B can only infect humans. Type-C also can only infect humans but type-C causes much less severe symptoms on average.

The matter has been explained too nicely to be understood even by a layman.

@varyolla435

No. Influenza spread through the militaries because you had millions of men living in close proximity to each other under often unsanitary conditions which is a boon for infectious diseases. The Influenza virus only lasts a matter of hours on surfaces which are absorbent. It is primarily spread via airborne inhalation. In military barracks and in underground trenches etc. then an infected person can transmit the virus to whoever is around them. 50 men in an underground bunker and one has the Flu = a day or two later many others now also have it who proceed to spread it to others and so on. In WWI both sides created huge underground caverns which sometimes housed hundreds if not thousands of men = perfect breeding factories for infectious diseases.

I don't really understand the whole issue with the Spanish Flu name. Like, yeah its not 100% factually accurate because Spain was simply the first to admit it struck their country but... its just a name. Just like how the West Nile Virus is just a name. Nobody is going around saying "damn those Spaniards, always getting sick n shit, why can't they be more like Portugal- the *better* Iberians" or anything else stupid like that. I just... I don't see the controversy that evidently exists.

The flu shot is not a guarantee that the recipient will not catch the flu. They have no way of immunizing against undiagnosed mutations. Flu vaccination effectively works in approximately about half of the healthy adults under the age of 65, that are vaccinated. The vaccine is not a silver bullet cure all. Some people that have been vaccinated may still catch the virus after having the flu shot, but the risk of illness is still reduced.
