translation.da: Hiv spredes ved seksuel omgang med en smittet person, når raske personer deler nåle eller sprøjter med en smittet person (hovedsagelig narkomaner) eller − mindre ofte (og nu meget sjældent i lande, hvor blod screenes for hiv-antistoffer) − ved transfusion af inficeret blod eller blodkoagulationsfaktorer.
translation.en: HIV is spread by sexual contact with an infected person, by sharing needles or syringes (primarily for drug injection) with someone who is infected, or, less commonly (and now very rarely in countries where blood is screened for HIV antibodies), through transfusions of infected blood or blood clotting factors.
