Isolated populations like SBH are different than large continental populations. Here in the USA the rising 'spikes' of case numbers are the best news we could have, as there is concomitant fall in death rates, and our population immunity is 'maturing'. This is due to longer time exposure of more people to virulent pathogens, perhaps mutation of viral particles, and numerous factors not clearly understood or identified by current testing (combination of developing cellular as well as humoral immunity). I just had to cancel a trip to HI, as they are still in a very immature stage of developing immunity, and are reticent to fully open resorts, restaurants and other attractions. The protection from the pandemic afforded by geographic isolation is now putting those sites behind Europe, Asia and the Americas, and it seems that SBH and like populations are going to take longer to develop immunity confidently.
