Thinking out loud …. Currently the United States has one-third of all confirmed Covid cases in the world (more than four times the country in second place) and one-quarter of all deaths from Covid. Additionally I remember a story regarding U.S. Customs recently (temporarily) confiscating medical supplies destined to the British Virgin Islands. Will there be an initial 'yin and yang' of U.S. citizens being 'persona non grata' and the need of tourist dollars? Once ready to open, will the welcome mat be selectively extended? I do have proof of immunity for measles, perhaps an immunity passport for Covid-19 is not so crazy.
