I agree and fear that we have not really begun to understand the scope of what is needed. IMO, disease is the major threat. I am mindful that after the 2010 Haiti earthquake, there was a cholera outbreak that killed thousands and sickened thousands more.

The destruction of so much infrastructure on Puerto Rico, the lack of clean water, etc., seems to me to be a set up for a plague of water borne disease that will make Haiti's 2010 outbreak look like a minor incident. Major efforts appear necessary now, but don't seem to be gearing up.
