Diseases in indigenous americans

They say that diseases introduced by the European conquistadors killed off as much as 95% of the indigenous American population. How come that the Europeans didn't suffer such casualties from the Americans' diseases? Didn't they have their own germs which the conquistadors were not immunized against?

Diseases don't develop everyone at the same rate nor do immune systems.
You suck at virtual ecology and immune system studies.

Superior genes. Literally survival of the fittest.
There's a lot of pop scientists (especially BLM) that says we should be afraid of ayyliums because their germs alone could kill us, but maybe it's actually our germs that will kill them

Advanced medecine and a probably stronger immune system (Europe was a crossroad for trade) prevented that. Natives were killed by their isolation, so to speak.

Hey idiots playing doctor:
It's not "stronger immune systems" it's "conditioned immune systems"...
and no, they're not the same thing.
Some people are conditioned via living side by side with PARTICULAR viruses and bacteria.
It's a roll of the dice which continents had which viruses developing where and who got to live by them.
It's a fact Europeans get sick as fuck when they go to some places in Africa and South America because Europeans aren't conditioned for those super uber extremely specific viruses.
It has nothing to do with general strength you childish dickheads.
It's all about random chance, whether egoists like to accept it or not.
You're not here because your ancestors were "better", they just didn't meet the trillions of ways they could have died.
Snakes, lighting, rock falls, meteor, viruses, falls, floods, tainted food, etc.
Deal with it. You're not special.

>How come that the Europeans didn't suffer such casualties from the Americans' diseases?
Because diseases is the politically correct way to explain disappearance of population. You don't want to say your kids in history class "hey, your ancestors are are mass murdered almost entire continent population"

I can drink milk and eat wheat.
I am special

...that dosen't explains at all why the natives died from european diseases and not the europeans from american diseases.

native americans didn't have sprawling population centers like the Europeans. thus, they didn't have the conditions necessary to develop plagues and the like.
instead of cities, they just sat around fucking each other until they developed syphilis and hepatitis.

All the natives didn't die you retard.
Do you think all native americans and south americans are dead?
Because it doesn't look like it.
And millions of Europeans died from plagues all the damn time, including by viruses in the amazon.
Are you fucking retarded?

Ok, being lactose tolerant is special. Congrats.
Wheat tolerance is nothing and wheat-free diet crap is just a new age fad started by the faggots at whole foods to sell more high priced speciality items. That's just a scientific fact.

>All
Never said All, and yes europeans died from plagues. That's not the fucking point. The point is the european's relative sucess in avoiding the diseases on american soil compared to the natives.
And up to 95% of the population got wiped out by the new diseases.

Guns Germs and Steel is a cool meme book which theorises about this.

ofc the spaniards got sick by the hundreds as well but they didn't bring it back to Europe and infected soldiers where surely isolated immediatly. Surely a few times a american mammal snuck on a boat and brought a disease to Europe, they had some nasty imported stuff as well.
But in general I think because of the harsh climates in most of Europe, compared to the mild or even tropical America, European diseases had a stronger attributes, which could help spread and infect faster than local american diseases.

Europeans domesticated animals and lived near them more than indigenous Americans.

does that mean we all have to be more dirty? :^)

According to the hygiene hypothesis in immunology, yes.

Syphilis came from the New World.

I once read that well before puberty the human immune system "decides" to specialize in either viruses or parasites.
Euros ate less wild game, and thus their immune systems were typically more specialized to parasites than viruses.

Oops...
typically more specialized to *viruses* than *parasites*.

>I once read that well before puberty the human immune system "decides" to specialize in either viruses or parasites.
Seems odd and I am genuinely curious about that, still got the reference ?

>still got the reference ?
It was from a book called "1491", it was a history OF pre-Coumbian history, how our perceptions of the Americas before Euro contact have changed over time.

so domesticated animals are more prone to catch viruses and wild game more prone to catch parasites?

tell us more

Natives were a lot more hygienic than europeans (who were notoriously filthy) and didnt have as well developed immune systems.

>tell us more
Sorry, that's all I've got!

>native americans lack immune systems adapted to european regional diseases

>no historical evidence to show their population could withstand constant disease exposure by frequent foreign trade as europeans did on a repeated basis.
>no historical evidence to show their population could tank constant disease by frequent eating various bush meat and get infected by misquotes like africans to the point where even their fucking blood cells adapted to it.

Native Americans didn't really stand a chance honestly. You basically had thousands of years of adapted diseases thrown at them almost all at once on top of constant skirmishes and war with a population with better tech, infrastructure and understanding.

Meanwhile native americans had almost nothing of note physically or technology wise. The sole exception was with the northern population inuits relatives who could tolerate everlasting winter and never really left their northern regions and thus was spared from disease, war and being absorb into another population genetically.

They died from smallpox, influenza, bubonic plague, cholera etc. Intentionnaly spreaded by white people. This is not a diseases you can adapt to. Stop telling bullshit.

> This is not a diseases you can adapt to

> Outbreaks of smallpox (i.e., caused by variola virus) resulted in up to 30% mortality, but those who survived smallpox infection were regarded as immune for life.
> We found that the duration of immunity following smallpox infection was remarkably similar to that observed after smallpox vaccination, with antiviral T-cell responses that declined slowly over time and antiviral antibody responses that remained stable for decades after recovery from infection.

> Persons who had multiple prior exposures to influenza viruses and other respiratory infectious agents before 1918 had diversely partitioned memory CD8+ T-cell repertoires and extensive portfolios of bacterial strain–specific antibodies. Their immune responses to infection with the 1918 pandemic strain may have controlled virus replication without increasing their susceptibility to bacterial invasion.

The articles above state otherwise, the key of course is it either required you to survive the initial illness during the first wave or be exposed to it multiple times with your immunity system gaining resistance to secondary infections not necessarily related to the first infection.
