What causes pityriasis rosea?

In recent years, with the improvement of quality of life, the incidence of pityriasis rosea has been increasing. So far, the main cause of pityriasis rosea is still not very certain. Today we will mainly understand the main causes of pityriasis rosea.

Pityriasis rosea is a common skin disease. When rose-colored patches of varying sizes and numbers appear on your trunk and proximal limbs, accompanied by scales, it can be determined that you have pityriasis rosea.

There is currently no evidence to support the main cause of pityriasis rosea. Studies have found that pityriasis rosea may be related to viral infection. In addition, some people believe that pityriasis rosea is related to Coxsackie B virus infection.

Clinical studies have found that the positive rate of serum Coxsackie B virus-specific IgM in patients with pityriasis rosea in the acute phase is significantly higher than that in the healthy control group, and the content of serum circulating immune complexes in the acute phase is significantly higher than that in the recovery phase. Neutralization tests and virus isolation both prove that patients are infected with Coxsackie B virus. These results suggest that the onset of pityriasis rosea is directly related to Coxsackie B virus infection.

In addition to the above causes of pityriasis rosea, the onset of pityriasis rosea is also related to a humid environment and low immunity. There are also reports that pityriasis rosea is closely related to drugs such as arsenic, bismuth, metronidazole (Flagyl), and captopril (captopril). In addition, some people believe that pityriasis rosea is related to bacterial, fungal or parasitic infections, and some scholars believe that it is related to allergic factors, but none of them have been confirmed. Recent studies have shown that cellular immune responses are involved in the occurrence of this disease.

In addition, some people believe that it is an allergic diagnosis of some infection or a skin manifestation of gastrointestinal poisoning.

Regarding what causes pityriasis rosea, experts tell us that the symptoms of pityriasis rosea are not obvious in the early stage and are generally considered to be a common allergic rash. However, in the later stages, you will find that the spots on the skin are becoming more and more, and they are the size of eggs, and are also accompanied by symptoms such as nausea and vomiting. Therefore, if you find patches of skin that are suspected to be pityriasis rosea, you should seek medical attention immediately to avoid delaying treatment and worsening the condition.
