Another difference is that because the USA in general and Florida in particular were so sloppy early on, it's estimated (from your linked article, and I've seen similar numbers elsewhere) that about 30% of Americans have been infected and carry some immunity, and around 20% have been vaccinated. There's some overlap between these but either way 40-some-odd % of Americans now carry some immunity. More importantly almost 60% are not immune.
That's not the case here. If the factor of number of actual infections relative to number of official cases is the same (3) then we've had about 7% of the population infected (seems plausible), and unfortunately thanks to the vaccine situation, about 6% vaccinated. That would suggest somewhere near 12% carrying some immunity allowing for some overlap. Means 88% are not immune.
It's a lot easier to get that famous "Re" factor below 1 when a good portion of the population carries some immunity.
