This is an interesting article. It would seem many, many more people in Jakarta have already had Covid than was originally thought. I suspect that Covid never disappeared from Thailand but obviously the testing got ramped up. If the true number of infections were known, the infection fatality rate could come down VERY significantly. As it stands, for me it seems I would have above a 99.7 % chance of not dying from Covid. That, I think it could be fair to say is an overestimate, possibly a significant one at that.
No?
