My son's friend has a group of what appears to be pimples above the top lip. It looks like a group of pimples with what looks like white heads. I want to make sure that this rash is not contagious. It almost covers the entire area above the lip and a couple of patches outside the group. Can you please let me know what this might be? Thank you...PS the child also travels outside the US regularily. If that means anything.
