Is 3.4% mortality per WHO not high enough or does it not warrant the precautionary measures? If at all, there need to be more precautionary measures, not less.

Is 3.4% mortality per WHO not high enough or does it not warrant the precautionary measures? If at all, there need to be more precautionary measures, not less. Poorer, densely populated countries in Asia and Africa are especially vulnerable since they will not be able to isolate populations or treat in ICUs or build 1000 bed hospitals in 10 days, and at 3.4% we're going to see millions of dead. I really really hope I'm wrong, but what if I'm not.
