Crazy question

Jan 10, 2013

If someone touched a sandwich with semen on his hands who was hiv positive and someone ate that sandwich almost immediately with a cut in his mouth is it possible to catch hiv from this scenario. Sorry if it seems a crazy question. Thanks Andrew

Response from Ms. Southall

Hi The answer could be yes, but there would have to be a lot of things that would have to take place in order for this to happen. First there would have to be a significant amount of semen on the sandwich, the cut in the persons mouth would have to be a new cut or sore that was open and bleeding, then when the person with the cut in their mouth had to bite exactly where the significant amount of semen was placed on the sandwich. Then the person's whose semen was place on the sandwich would have to have a very high viral load as well. If they were on medication we know that having an undetectable viral load decreases the risk of HIV transmission by up to 96%.

So there's the answer, probable but highly unlikely!

Be well and stay safe, Shannon
