I did think about this some weeks ago, when the Corona virus first hit the mainstream. Albeit in the context of "globalisation" being the conduit for the increasing ease with which "pandemics" spread.
As an example, the Black Death originated in China in the early 1300s, yet took decades to reach (via the trading routes), northern Europe. I don't think it reached the Americas.
The Spanish Flu of 1918 - 19 went worldwide, infecting c. 1/3 of the population (and killing c. 1/10 of those), in less than two years.
It appears that Corona virus could be close to going worldwide (albeit, without infecting a significant proportion of the population (yet), in just a few months. Hopefully, the quarantining will reduce the prevalence).
