The answer is no, because the concentration of HIV in saliva is far too low to pose a risk of infection. Here are ways you can get HIV:
- Contact with infected blood, semen, or vaginal and cervical secretions with mucous membranes or an open wound;
- Injection of infected blood or blood products (i.e. with shared needle;)
- Transmission from infected mother to fetus and during breastfeeding
If you’re sexually active, make sure you’re practicing safer sex by using a latex barrier.
