No, most doctors believe it is caused by a respiratory virus. You only contract pityriasis rosea once in your life, and not again. This is part of the reason why the medical community believes it is caused by a a single DNA-based virus (belonging to the herpes family, like chicken pox). It is not caused by any contaminants or toxins.
