Possible transmission by sharing water bottle

Hello!
I have a very urgent question and I really need your help!
Ι was at a gathering yesterday and a friend of mine took my bottle of water by mistake. I am wearing braces so I have small wound in my teeth. My viral load is 1690 IU/mL (undetectable). Is there any fear for infection??? To be honest I am freaking out.
Sorry if it does not belong here but I don’t know where to ask. I am really worried (@HealthExperts).

Best,
Andreas

Hi Andreas,
Your viral load is quite low and this is a very low risk exposure event, so the risk of transmission is negligible (although probably not zero).
Does you friend know about your hepatitis? The safest thing would be to inform them so they can have follow up testing if they have not previously been vaccinated. If nothing else it might motivate them to get vaccinated now!
So there is no need for either of you to get anxious, but it would be most responsible to follow up to be 100% sure.
I hope that helps.
Best wishes

She has been vaccinated (she is 26). That means that there is fine. Correct?

Correct, but the presence of protective antiHBs titers must be demonstrated

Dear Andreas_R, you do not need to freak out!! First of all you have low viral load. Second of all, even if a microscopic amount of virus was in the water, the person’s saliva and gut would kill it. Hepatitis B virus is not going to be transmitter by a microscopic drop of blood through sharing a water bottle. The U.S. Centers for Disease Control and Prevention (CDC) - and the Hepatitis B Foundation - clearly state that hepatitis B is not transmitted through the sharing of food or drinks. So please, please don’t freak out!!! So sorry I didn’t get to respond earlier. Stay in touch and let us know how you’re feeling now? We really appreciate your turning to us for advice and support. That’s why hepbcommunity.org was formed!!! Always, Joan

Dear Ms. Block,
Thank you very very much for your warm response!!! I talk to the two doctors that monitor me and said the same thing.
I am trying to relax as it has been a stressful day to be honest. But knowing there is no problem is really important. So, I will relax.

I really appreciate your advice and support. I wholeheartedly believe that this community has helped me with its presence (not just today) in so many ways. I am really thankful that this community exists!!!

Again thank you very very much!
