The mark consists of a multi-colored medical cross encapsulated by a multi-colored circle and bearing certain text to the right. Both the medical cross in the center of the circle and the circle itself are intersected by two wavy lines which meet in the middle and divide both the cross and the circle into four equal sections with each section having a distinctly different color. The top section of the circle having the color orange, the right section of the circle having the color green, the bottom section of the circle having the color blue, and the left section of the circle having the color red.
