It doesn't matter - what matters is the point when hospitals get overwhelmed. Past that points, fatality rate goes up just from lack of treatment. Societies have already proven they can put in sufficient containment practices to keep hospitals from getting overwhelmed, so it's a matter if other countries follow similarly effective practices or let themselves get overwhelmed.

I think this in and underdeveloped topic; as I see it this infection even if it is comparable to the flu in mortality require often more intense medical intervention.
