If you have Ulcers on your bottom lip and you swallowed some of your friends blood and it was only a tiny amount of blood like when you pick a scab and it bleeds, can someone please answer this?
Hello and thanks for reaching out to the AIDS Vancouver Helpline with your question.
It seems that you are concerned about contracting HIV from swallowing a small amount of blood from your friend's mouth. We are glad you asked the question.
Normally we would require more information in order to determine the risk of any activity. However based on the information that you have provided we consider the activity to be a Negligible Risk activity. This means that although there is potential for HIV transmission because the activity involves body fluids, there has never been a confirmed report of HIV being transmitted this way.
The other reason the risk is negligible is that saliva has enzymes that inhibit the transmission of HIV. By exposing the little blood to saliva in the mouth, this reduces the level of risk. In the normal circumstances kissing is considered a no risk activity.
CATIE has additional information on HIV transmission as well as HIV prevention methods. AIDS Vancouver Online Forum has got some postings that are related to your question. If you have additional questions feel free to contact us again.
Thank you for contacting the AIDS Vancouver Helpline.
