What causes pityriasis rosea?

Doctors don’t know exactly what causes pityriasis rosea. Some doctors believe that pityriasis rosea is caused by a viral or bacterial infection. Certain medicines can also cause this rash. Pityriasis rosea is not contagious, so people who have this rash do not have to be kept away from other people.
