Is saliva kills hiv some doctors say it don't kills we get hiv from talking as saliva comes from other person ?

No risk, no worries: Duplicate question (?), same reply. HIV is transmitted only by sex or direct exposure to blood, i.e. blood into your bloodstream. There are no exceptions; nobody ever catches HIV without sex or blood exposure.

If this is your only risk, don't get tested. ...Read more
