However the phenomena holodovoj allergies arise not only at the general action of a cold, but also at local action. For an example it is possible to result a case with 12-year-old Igor at whom for the first time changes on a skin have arisen in the winter after the child long time was on a frost without gloves. Having come back home, the boy has felt an intolerable itch of a skin of brushes of hands, there was its considerable hypostasis.

Pertinently to notice, that the slowed down variant of realisation of MAIN displays of an allergy when they appear in 9-18 or 24-72 hours after cooling is possible. Besides, distinguish the primary got and family forms of an allergy to a cold.

Among children risk group persons with complicated allergologicheskim the anamnesis and the centres of a chronic infection (make caries, a chronic tonsillitis, helminthic invazija and others). That is, kids, with the raised propensity to allergic reactions of an organism.
