couple days ago, i descovered some blood on my finger
i searched for wound it might come from but i couldnt find one.
so i think that i grabbed something on the street or somewhere which had blood on
i think that i ate food and smoked some cigs with this "dirty" hand
and despite fact that i know i might get something from this person's blood - im interested, how are my chances to catch something? i mean without direct impact of this blood to my mouth
just through fork or cig or dunno
Sometimes you can have a small wound that dries up and you don't notice it. The blood could have come from here.
If you did get the blood from something on the street, I don't think you have anything to worry about. Especially if you never stuck your finger in your mouth or if it never touched the food. I'm not sure about the cigarette. Did you pull the cigarette out with the same hand/bloody finger?
Observe how you are the next few days. Look out for any strange symptoms. Oh, and definitely mention it to your doctor.
