In development of a disease the great value is attached to the postponed infections (flu, quinsy, etc.), to existence of the centers of persistent infection (an adenoid disease, antritis, pyelonephritis, etc.), to vascular changes, immune disturbances. Among the factors promoting development of a parapsoriasis the immune disturbances, allergic reactions, dysfunctions of endocrine system, various infections and viral diseases playing an important role at an acute varioliformny parapsoriasis are noted.
