Since the death rate from this virus looks like being around 0.5%-1% once all the hidden infections are accounted for, my guess for Indonesia currently is 157 announced deaths, so probably 1000 deaths considering most would not be discovered or counted, meaning around 100k-200k infections currently in the country. There is no vaccine coming this year and even if it did, most Indonesians wouldn't get it. Lockdowns won't work very well here.
I'm trying to think of how an infection count of 100m, with death count of 1-2m in Indonesia will be avoided. I'm not sure I can see anything on the horizon. OK there aren't that many very elderly, but then 67% smoking rate and generally poor health. The hot season may slow transmission a bit, but that's about it ... It starts to look like the worst case scenario is coming.
