A physician has set up a clinic in the Ritz-Carlton on Canal Street: an email from Tuesday:

The health care situation here has dramatically worsened overnight. Many people in the hotel are elderly and small children. Many other guests have unusual diseases. We have commandered the world famous French Quarter Bar to turn into an makeshift clinic. There is a team of about 7 doctors and PA and pharmacists. We anticipate that this will be the major medical facility in the central business district and French Quarter.

Our biggest adventure today was raiding the Walgreens on Canal under police escort. The pharmacy was dark and full of water. We basically scooped the entire drug sets into gargace bags and removed them. All under police excort. The looters had to be held back at gun point.

In all we are faring well. We have set up a hospital in the the French Qarter bar in the hotel, and will start admitting patients today. We are anticipating to dealing with multiple medical problems, medications and and acute injuries. Infection and perhaps even cholera are anticipated major problems. Food and water shortages are iminent.
