Yeah, except we got smallpox in the trade...
I have my scar, but they stopped vaccinating against it long ago. And I don’t believe, NOT FOR A MINUTE, that it has been totally eradicated, I would bet just about anything that there are small isolated pockets and vectors that we don’t know about.
Some dam BS door-mouse that lives in Pukistan...
They used to blame Europeans for bringing smallpox to the “pristine and innocent” New World... until a few years ago when proof was found in Peruvian mummies that smallpox was here at least 500 years before Columbus.
Another cliche bites the dust.
