Find the difference.
(correlation is not necessarily causation, but still a striking correlation of mask-usage and #covid19 growth rate)
My guess: masks block virus-to-community shedding directly at the source (mouth nose), even from pre-symptomatic cases.

@BakuninsTraum Why presume that is masks and not any of the other countless differences..
1) strain difference (already proposed with some limited evidence to support it)
2) Bleach blowing trucks which as far as I can tell have been used exclusivly in asian countries
3) earlier use of quartine, the ones labeled "no mask" were infected later once the virus was already known, so quicker lead time on action. more people self quarantining out of fear, etc.
4) Asian countries have seen previous cases of SARS and other coronavirus family viruses. Perhaps they have some immunity as a result of that.
