The social structure of patients of the burns unit in 2008 year, hospitalized with hemocontact viral infections (HVI), was analyzed. 764 patients were treated, HVI was diagnosed in 103 of them. Men had HVI two times more often then women. The possibility of HVI was higher in patients with fire burns. The lager the burn area was, the higher was the possibility of HVI detection. Patients with HVI were reliably younger with average age of 33,1years; the majority of them were unemployed. The most socially problematic group was represented by patients with mixed HVI - unemployed youngsters of the capable age, the majority of them were drug addict.
