How is pityriasis rosea caused

summary

Many people may not have heard of pityriasis rosea, but it is a common disease in real life. I had this disease some time ago. Here are some experiences I know to share with you.

How is pityriasis rosea caused

First of all: pityriasis rosea may be related to virus infection, but so far no virus has been isolated. It has been reported that arsenic, bismuth, metronidazole (metronidazole), captopril (captopril) and other drugs can cause pityriasis rosea like damage.

Secondly, other scholars think that it is related to bacterial, fungal or parasitic infection, and some scholars think it is related to allergic factors, but they have not been confirmed. Recent studies have shown that cellular immune response is involved in the occurrence of the disease.

Again: pityriasis rosea etiology is unknown. Is the virus or bacteria are not confirmed, it is an inflammatory self limiting skin disease, generally 4-8 weeks to subside, not easy to relapse, there will be individual patients may eat some three to six months, is not very good treatment, need patients to do symptomatic treatment.
