Hi, I have recently re-read Diamond's Guns Germs and Steel and I was left wondering:

Europeans brought all the devastating Old World diseases to the Americas in 1492, and the diseases spread quickly in all directions devastating the continent's native population. The devastating effect of these diseases can be attributed to the lack of immunity to them in the native populations.

However, the arrival of Columbus to the West Indies in 1492 was not the first contact of Europeans with the native peoples of the Americas.

Vikings visited North America in around 1000AD. According to sagas they met with the local Inuit population. Diamond and Wikipedia both claim, that perhaps Norsemen from the Greenland colony regularly sourced wood from mainland North America.

Lastly, the Norse Greenland colonists were in long-term contact with the Inuit who came to Greenland from North America (both trade and war), which is well attested in both written and archeological evidence.

My question, therefore, is: Is there any evidence for a widespread epidemic in the Americas after 1000AD, that could be attributed to the Inuit contact with Vikings? Most of the diseases that devastated the Americas in the late 15th and early 16th century were already well established in the Old World prior to 1000AD, so the Vikings would definitely be exposed to them before the contact with the Inuit. I also suppose that the Inuit were not completely isolated from the rest of the New World population, so the potential potential epidemic would spread to other native groups.

I'd be grateful for any reply.
