I check the graphs in the Bali Covid-19 Facebook group from time to time and, at least for now, the numbers are moving in the right direction.
As far as I know, aside from Nyepi there has never been any significant lockdown in Bali, like what has been done in Australia. The main evidence of Covid that you can see here is that most tourist related businesses are closed. The rest of the places like in the cities, people are moving freely around.
Is it possible Bali is building herd immunity? I hope people don't get complacent about it and continue to wear masks and so forth, but it would be nice to see the number of cases going down and down. I doubt though it would be able to eradicate it completely, at least until a vaccine comes along.

I think most (if not all of us), still don't understand the
new Covid (including real experts and even governments).
It's far too early to tell.
Many people also don't really understand much about 'vaccines', and hope when one comes along that actually works, it'll be like a silver bullet.
Graphs and numbers have their place, so long as they're from 'reliable sources' and showing relevant data. The pretty graph above looks like it's showing 'daily new positive cases' going down. What about death rates, hospitalizations, 'recoveries', etc? What did the 'Bali Department of Health' base the graph on? How much 'testing' was done, what 'tests', where, by whom, etc?
'Herd immunity' is also poorly understood. A vaccine
could help, or, not by much. 'Natural herd immunity' would mean letting the virus infect a large percentage of the population (including letting many people die), and then hoping for the best. (It's not even known yet if those with the antibodies will stay 'immune', for how long, or even if they can be reinfected at a later stage?)
What

I suggest that those who would like to learn more about these issues read through some other sources rather than jumping to broad over-simplifications.
Try the following one (I'm not saying it's the 'best'), but a reasonable start:

I wish for all of us (everybody) to have a safe future.
