Quarantine completely failed to prevent what was a highly localized disease globally in 2 months. We need to accept it’s simply ineffective across international borders unless draconian measures are applied before they seem required. We might get through this with 100,000 people dying globally or 100,000,000 it’s completely unknown at this point. But, should the second happen expect some significant changes to happen for years if not decades.

PS: China’s case fatality rate broke 4%, though they likely undercounted cases by ~50% if not more.
