Licking Blood, "blood brothers" and similar types of exposures

Question

I,M WONDERING CAN YOU GET AIDS OR HIV BY LICKING SOMEONE ELSES BLOOD.

Answer

Thank you for your question.

If you get someone else's blood in your mouth, and they are infected with HIV (or another bloodborne disease like hepatitis B or hepatitis C), you would be at risk for infection. The more blood that you get into your mouth, the greater the risk of infection with these viruses. As a general rule, it is best that you do not allow another persons blood to get into your mouth.

Likewise, customs like "blood brothers" or "blood sisters" (where blood can be exchanged between people to show trust and friendship with one another) can also put a person at risk for these diseases. Customs like this can allow one persons blood to get into the bloodstream of another person, allowing transmission for these viruses to occur.

As a general rule, always avoid another persons blood from getting into your body.
