Google tells me that Taiwan has had a grand total of 124 deaths for a country of 23 million people. That's 0.00053913% of the population, while the US has had 594k deaths for 328 million people - 0.18109756%. Taiwan's "wave" looks like a slow day for the US.

You're talking about total cases while I'm talking about recent cases. Shouldn't the continued use of masks prevent recent cases in Taiwan? What changed?

On top of that, it's pretty clear by now that East Asian populations have some level of preexisting resistance to this family of respiratory viruses, given their proximity to past outbreaks of genealogically similar viruses. It would make sense that their totals will eventually be lower than those in parts of the world that haven't been exposed to SARS like viruses.
