Is Henoch-Schönlein purpura contagious?

Henoch-Schönlein purpura (HSP), also known as acute vascular purpura, is often mistakenly believed by many to be contagious. Is this actually true? Details are as follows:

HSP is not contagious, as it has neither a source of infection nor a route of transmission. It is a common autoimmune disorder.

Current treatment for HSP typically involves selective pharmacological therapy. Rutin compound tablets may be prescribed, supplemented with certain vitamins and calcium gluconate; combination therapy yields favorable results and effectively alleviates localized petechiae in patients.

In patients with severe rashes, fever may also occur. In such cases, corticosteroids may be selectively administered. Corticosteroids possess potent anti-allergic properties and can reduce vascular permeability, thereby rapidly relieving patients’ discomfort. Prednisone is one commonly selected corticosteroid.

Most patients experience marked clinical improvement following treatment. For patients with severe renal involvement, pulse corticosteroid therapy may be employed—this approach also demonstrates good therapeutic efficacy.
