WHO's logo mark with Asclepius, a god of medicine, and snake around the stick
Dracunculosis was endemic along the Red Sea in the era of the Old Testament. Guinea worm was called "fiery snake". Actually, the snake around the Asclepius' stick is the Guinea worm! It can be supposed that in the Greek era, Mr. Asclepius was especially good at removing the fiery snake by using a stick.
