gollark: China didn't exactly *help* things by covering it up initially, but America was/is definitely not doing great either.
gollark: The UK is at least taking it somewhat seriously, if not actually handling it that well.
gollark: North Korea is probably just doing a combination of not testing, reporting no accurate data whatsoever, and killing anyone with bad symptoms.
