Can pityriasis rosea be prevented?
There is no definitive prevention for pityriasis rosea, as the cause is not yet fully known. As with most viral infections, helpful prevention tips may include good basic hygiene, hand washing, and avoidance of ill contacts and of aerosolized respiratory droplets from people coughing or sneezing.
What is the prognosis for pityriasis rosea?
The general prognosis for pityriasis rosea is excellent as most cases clear even without treatment within nine weeks.
Pityriasis rosea will, in nearly all cases, clear completely on its own, with or without medical treatment. It typically leaves no long-lasting scars, although some mild, temporary skin discoloration called post inflammatory hypopigmentation or hyperpigmentation can occur in people with darker skin. It has no known long-lasting side effects and has not been associated with any other diseases.
Symptoms may be reduced with topical treatment or taking extra precaution to prevent overheating, and the rash will usually clear on its own in six to eight weeks. Once a person has pityriasis rosea, they generally have lifelong immunity.
Where can I find more information and facts about pityriasis rosea?
A good source of information is the American Academy of Dermatology (http://www.aad.org) or a board-certified dermatologist.
