Hepatitis transmission via contact

[Leaffy]

Hello,

I might start by stating that I have a temper of extreme paranoia and anxiety hence the question.

In fact, I have one simple question and I would appreciate it to be answered by a professional medhelp.

A scenarios that happened few months ago is haunting me : I came in contact with a brothel door knob, and since that moment I can't  put my mind away from the idea that I came in contact with a certain STD (and especially Hbv since it stays alive for 7 days outside the host), few minutes after I reached to my pocket with same hand that touched the door knob and took some change to buy something, few minutes later I touched an ATM machine keyboard.

Now my fear comes from the fact that I might have took something from the doorknob and put it on the environnement (money change and ATM machine that might have been already infected and I did infect them further) and then somebody came and touched the same spots I touched and this same person had to have syringe on a spot that was touched by his hand (without applying alcohol).

I'am conscious that the paragraphe above is a science-fiction novel but it has been eating me from inside for months.

Please, I'am asking you for a well founded answer with scientifique explanation (usually doctors don't have the patience to answer me with enough details and by looking at what I ask I don't blame them)

I just need a honest decent and well founded with scientifique information answer for onces and for all !!

Thank you,

Regards

Obviously you know this is very far fetched. Otherwise every person on this earth would have hepatitis. Unless someone left a cup of blood on said door knob there likely couldn't be enough virus, and it would obviously need a direct path to your blood stream also. First the chances of hep being on the door knob itself is probably one in many 100 millions, 2nd the chance of enough of the virus being on that knob is probably one in many billions, and the chances of there being a cut perfectly placed on your hand that touched said knob just right is probably one in many millions. Meaning you had no risk.
