Yes, the HIV virus can be transmitted by the bite of someone infected if there is contact between the victim's blood and the contaminated blood of the aggressor. To do this, the bite needs to be strong enough to make the victim bleed and the person infected with HIV has some bleeding or bruising in the mouth.
This is a very rare situation, but it can happen. For example, during a convulsion, if the HIV-infected person bites their tongue and involuntarily bites the person who is helping them, it can be contaminated with HIV.
Health professionals, caregivers and family members should take extra care with AIDS patients suffering from psychiatric disorders in order to avoid a possible bite of aggression.
However, it is important to stress that, in order to be able to transmit HIV through a bite, there must be blood mixture. There are no reports of contagion through saliva.
Remembering that HIV can be transmitted through unprotected sexual intercourse, contaminated blood transfusion, sharing of contaminated needles, an accident with contaminated shearing, and still from mother to child during pregnancy, childbirth or postpartum.
In the event that someone is bitten violently by an HIV-infected person, to the point where the bite causes bleeding, it is best to seek a Health Unit for the HIV test. The test is offered free of charge by the Unified Health System (SUS).
