Usually not, despite what the books say. Kids get it on the chest all the time.

i thought that it was an std?
Don't know. But it happens all the time, kind of like when you catch a cold--most of the time, who knows where you got it?
Dr. Rockoff
if it is not contagious then how did i get it?
Not much. If you don't see new ones, I suggest you not needle anything, since it's hard to tell the little marks left over (until they disappear) from actual mollusca.
As to contagiousness, I don't find the condition contagious in anyone--I see all ages with it, and rarely does anyone nearby have it. So in your situation, you certainly should be OK.
Best.
