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.
translation.lv: HIV izplatās dzimumkontaktos ar inficētu personu, lietojot kopīgas injekciju adatas vai šļirces (galvenokārt narkotiku injicēšanai) ar kādu, kas ir inficēts, vai, retāk (un pašlaik ļoti reti valstīs, kurās asinis pārbauda uz HIV antivielām) ar inficētu asiņu vai asins recēšanas faktoru pārliešanu.
