Melanin ( white patches )

I met a lady and spend some close time with her, she has melanin deficiency ( white patches on body ) - I'm scared it can be transmit to me ?? What are the modes of transmission ??

Melanin deficiencies are NOT contagious.  

Melanin is the pigment that gives our skin color -- there is no 'mode of transmission' unless you count from a parent to a child.  As example, you cannot be transmitted a skin color, except by your parents.  So unless you plan on becoming this woman's child, no worries ;).
