Vasculitis is not contagious. Vasculitis itself is a series of diseases caused by various physicochemical factors, including infections and metabolic reactions, resulting in damage to the intima, followed by inflammatory cell infiltration, and the development of intravascular thrombosis. The classification of this series of diseases is very heterogeneous and the clinical manifestations are diverse. Sometimes the cause of vasculitis is caused by a specific viral infection, but the cause of vasculitis is not the virus itself, but due to the immune response of the body, so vasculitis does not spread to each other and is safe for the person caring for the person with vasculitis or the family member with vasculitis.
