I honestly do not know how soon one can get herpes (an outbreak, I mean) once it is contracted but yes, you can get herpes and any other contagious infection from face painting, or anything else that one comes in contact with an infected object or person. I'm very surprised in this day and age that the person doing the face painting did not use new/fresh instruments for each person. Very surprising. When our church does face painting for our annual Harvest Festival, the person doing the face painting uses Q-tips and discards the used ones right away. It's very unfortunate if this is how the child contracted such an infectious disease.
