Temporary: Rash with oval lesions limited to trunk. Rarely involves face or extretmities. Lasts usually 8 weeks and as long as 14 weeks. Recurrences are uncommon. Will clear a few weeks faster in some with oral erythromycin. This does not leave marks.It is not contagious.

Pityriasis rosea: The exact cause of pityriasis rosea is unclear, although the cause may be a viral infection, such as infection with certain strains of the human herpes virus (hhv6 or hhv7). Pityriasis rosea, however, isn't believed to be contagious.
