Hi! if i kiss someone who has vry small amt of blood in his saliva,can i get hiv by kissing him? does saliva can kill hiv even if blood present?

Unlikely: there are several variables involved with this question. theoretically it would be possible, but low chances. i would have a test done now and in 6 months to completely relieve your nerves. good luck

No HIV Risk: Nope. Fortunately there is zero risk of HIV in this scenario, even in the HIGHLY UNLIKELY event that there is 'blood' in the salvia.

Yes: You can contract infections including HIV with deep kissing. It is more likly if you have a open cut as well. It is not a common way to transmit the virus but not impossible.
