Mosquito borne illnesses in the America’s without African Slave Trade

It seems that the big Mosquito borne illnesses largely established themselves in the America’s through the Slave Trade.

So, had we avoided the Slave Trade (which has obviously been discussed), how likely is it for most of these diseases (Malaria, Yellow Fever, etc) to pop up? And would their worst forms make it?

And if they can be avoided, how big is that butterfly? I would imagine that close to a nine digit figure for lives is saved. That colonization is more widespread in tropical places and exploration of the interior of South America is more widespread in the early days.

Even if the introduction of these diseases is just delayed a half a century or two, how impactful is that?

how did they get over to the Americas? through the slave trade
 
From Africa, presumably from the Slave Trade.

Except there was malaria with the Spanish and Portuguese before they had traveled to Central and South America, decades before there was a need for Africans slaves to replace the Indians, who were suffering from Malaria as well as all the other new diseases in the early 1500s.

I was basing the Malaria claim off of this.

I got too excited and posted the thread too soon. After skimming through an academic article it sounds like the slave trade may have contributed to Malaria over time, but didn’t generally cause it. I’m guessing the same is true for most of the Mosquito borne diseases?

I guess I jumped the gun with this one and don’t get any points today. :oops:

But no slave trade would still seemingly effect things like Malaria and other diseases genetic diversity and effect the number of strands, while delaying when various things show up. Maybe the thread could be about that.

There was malaria - swamp fever in Europe even Scandinavia from early on. Denmark was repeatedly ravaged by this in the 1830's. Guess you have to look somewhere else..
