I heard that it is possible to get AIDS after being bitten by infected people. I know some children are especially prone to biting each other. Kim Loos Dr. Kimberly A.

Some young children go through biting stages.
They should certainly be discouraged from exhibiting this behavior for obvious social and health-related reasons. As of March 1999, I am only aware of one documented case in which a person tested HIV positive after being bitten by an infected person. This is because the biter had open bleeding sores in her mouth at the time of the assault and caused open bleeding wounds to her victim. Blood contains a much higher concentration of HIV compared to saliva. The good news is that, over the years, we have taken hundreds of calls from police officers and children saying they were bitten, and none have resulted in transmission of HIV', Liberti said.
