HIV is transmitted (spread) from a person who is infected with HIV to somebody else through the body fluids of the person who is HIV-positive. We need two things for this to happen: a high-risk body fluid and an entry point into the bloodstream.
Virusi vya HIV huambukizwa kutoka mtu mwenye virusi hivyo kwenda kwa yule ambaye hana virusi. Vinapitia maji maji ya mwili la mtu mwenye HIV. Tunahitaji vitu viwili ili hii kufanyika: maji maji ya mwili yenye hatari ya juu na eneo la kuingia kwenye mfumo wa damu.
