Tropical Fruits: Papaya Tree Leaves Gone Bad, 1 by zapatero

The new leaves on one of my papaya trees are coming in very disfigured, and are about half their former original healthy size. This began about three weeks ago, and is becoming progressively worse. Can anyone identify the disease, and if so a treatment, from the attached photo? (You can see some older leaves at the bottom and the upper right of the photo for comparison.)

(Actually, I have more "before" and "after" photos; but I didn't realize that I would be able to attach only one to this posting. Please ask if you would like to see them, and I will post them individually.)

Thank you very much for any assistance,
