I would like to see some evidence of the Native Americans experiencing diseases brought to the Maya by the Vikings included bubonic plague, chicken pox, pneumonic plague, cholera, diphtheria, influenza, measles, scarlet fever, smallpox, typhus, tuberculosis, and/or whooping cough.

Not wide spread perhaps, but evidence in local populations...

Also the Maya liked to bury their sacrifices close to the temple or with the deceased Lord the sacrifices were honoring, have any European skeletons been recovered?
