I read other posts here but wanted you to hear my story. 

 I was drinking with friends and their friends. We were all sharing drinks all night. It was dark, so I can’t say if anyone was bleeding from mouth. If they had cuts in mouth. If there was blood in the drinks that were shared. I don’t know. 

All I know is that I have a Kanker sore in my mouth. Medium size.  Mine has no bleeding but it was still alittle painful and still white look to it. 

I don’t think I would worry but MY kanker sore is the question. If a drink did have blood from there mouth and I drink it with the kanker sore I have in mouth, am I in risk of HIV? I have siblings and I don’t want to put no one in risk. Please help and calm my nerves. Thank you 

The episode you describe was no risk for acquisition of HIV. You do not know that your friends have HIV. Even if they do, HIV is not transmitted on an animate objects such as when a bottle is passed from person to person.  Further, HIV is not transmitted when swallowed. Finally, HIV is not transmitted in saliva.  The fact that you have a canker sore does not change my assessment in anyway. There is no reason for concern and no reason for testing. EWH

What got me is the open wound statement. There’s a few style definitions when it comes to what is considered an open wound. From fresh cut with blood to canker/cold sores. 

Can you put to rest for me the open wound transmission and what type of wound, if any, transmits HIV? 

Why a canker sore wouldn’t fall in the category for this scenario with sharing drinks?

Dr. Google is the worst thing to do when trying to look for ANY answer. I definitely wouldn’t recommend that to anyone. It’s a nightmare. 

Thank you again. 

Your answer would be the same even if there may have been blood on the glass/bottle?

The open wound misunderstanding is very common.  It originates from the fact that some STI sores such as those caused by syphilis and herpes have the lymphocytes targeted by HIV in the base of the sores.  These target cells can become infected.  Other open sore, cuts and scrape, including canker sores, do not have these cells in their base and therefore do not increase the risk of infection.

Please don’t worry.  EWH

I haven’t been intimate orally or sexually with any woman in a couple years. Not sure if syphilis mouth sores are recurring if I did have that?

Other than that, to recap, that canker sores are not a point of transmission due to these type of sores because they don’t have the right cells to be a place of infection for HIV. Also, HIV, with blood or no blood, can’t be passed on by sharing drinks because it doesn’t transfer through objects, can’t be transferred through saliva and can’t be transferred from swallowing. 

I know this is my last time responding, so thank you for your time Doctor. I appreciate it very much so. 

Thank you again Dr. It was a pleasure.

The lesion you describe on the inside of your mouth sounds like a typical canker sore and not a syphilis ulcer. Syphilis ulcers are typically painless and do not recur.. In addition, they appear on average three weeks following a sexual encounter during which Syphilis is acquired. The fact that you have not had Sex recently adds to the multiple reasons that it is virtually impossible that the lesion you describe is due to Syphilis.

You are also correct that Syphilis would not be acquired by sharing a glass or a bottle with an infected person.

I urge you to put concern you have about a possible infection from the event you describe aside and move forward. I see no reason for concern and no reason for testing.

This will end this thread. Take care. EWH.

Just wanted to make sure that I understood you correctly.
