Italy and Sweden are substantially at the antipodes.
Here in Italy we adopted a severe and prolonged lockdown, which was successfull pushing the R factor well below one. In 2 months this allowed to reduce the number of carriers, keeping 96% of the population not infected.
In Sweden there was no strict lockdown, and the virus was allowed to spread.
But, due to the lower population density and the cultural differences, the R factor was just above 1, whilst here in Italy, without lockdown, it was almost 4.
With a relatively low R factor, Sweden had the virus slowly infecting a significant percentage of their population, including mostly the people with greater mobility and more frequent contacts.
They never reached the saturation of their ICUs.
However the death toll has been high, they are now close to Italy at 560 deaths/million. We are at 580, but this was caused by the incredibly high mortality in just 3 towns, where the health system collapsed.
With the population density and the Italian behaviour, if we adopted the same strategy as Sweden, our death toll would have been 10 times larger, as those three towns did clearly demostrate.
Coming back to touristic travel: what do you think is a better visitor for Cozumel? An Italian or a Swedish?
There are good chances that the Italian has never been in contact with the virus, whilst the Swedish is possibly already immune. Italian tourists are not following social distancing (nor any rule in general), the Swedish ones are usually more regulated.
Let see what Cozumel operators would prefer to get, considering that getting US citizens will probably be very difficult, and defintely very dangerous.
For me, I would say loud to everyone "please stay at home" until the pandemic is over...
