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

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. Saliva kills the virus, so even if someone had HIV, and if it were mixed with blood, the exposure you describe would be considered zero risk. If this is your only risk, don't get tested. ...Read more

Uncertain, but...: I am afraid there have been no exact studies to address the connected concerns in your scenario. But contracting infective agents may take place as long as the external natural barrier like skin or mucosa is broken by sex-related acts. And the related symptoms may develop if internal humoral immunity is not strong enough to fend off the invading infective agents. Nonetheless, seek evaluation... ...Read more

Could you tell me if there is dried blood on my desk at school could i catch the HIV virus or aids virus?

Wimpy Virus: It is important to remember that viruses like hepc, HIV and others are strings of proteins that are connected by very weak bonds. They require many things to stay active and need living cells to reproduce and survive. Unless that gross blood, mucous or some other organic substance got into your mouth, anus, vagina or open wound, the odds are very unlikely. ...Read more
