I think Arney has touched on the central and hardest problem to be solved. How to get the help and supplies distributed throughout the city, and how to get it into the hands of the people who need it and not the profiteers.

In addition, soon, if not already, the decomposing dead and lack to sanitary facilities are going to render whole areas uninhabitable. Removal and burial and setting up sanitary facilities are as urgent as getting food and water to the survivors.

IMO the amount of effort needed to organize and run the distribution of aid, and removal of the dead is far far greater than anyone has even begun to think about: and these are things that need to be done now.

I hope I'm wrong, but I think the worst is yet to come.
