Can you contact hiv if someone is talking and they spit a bit of blood out there mouth to cut on your body?

The risk of contracting HIV from an infected person's saliva is extremely low. There must be direct contact with infected blood, semen, or other bodily fluids to contract HIV. Saliva does not contain enough of the virus to cause infection. Therefore, the probability of infection from a splatter of blood from a person's mouth is negligible.
