Geographically speaking the quarantine actions of Europe and the Russian/central asian realm is requiring significant effort to control, limit and properly quarantine passenger coming in through ports, airports and through land borders.

Aside from land borders other ports of activity, sea and air, input is limited to single nodes of entry.
