<s>[INST] While running in the park this morning I saw a woman take a hard fall off of a bike and I stopped and joined two others to attend to her, get her to the side of the road, await medical assistance, etc.  When I left I noticed a drop of her blood on my hand, she was bleeding pretty good from her chin where she hit the pavement.  I washed it off immediately with the water I had with me, although I was a couple of miles from home so it was about another 45 minutes before I got in the shower for a full scrub.Anything to be concerned about, do, keep an eye on?Thanks. [/INST] Hi. Thanks for the query. As per your complaint blood-borne infection can occur from one person to another in case if the blood from one person reaches under the skin of the other person, and it can occur if the other person has a break or laceration over the skin surface which is exposed to the blood. If you do not have any broken skin or laceration in the area where the blood Chat Doctor. But in case if there has been some laceration, or you got any small injury in the same area while helping the women there can be chances of infection, and you can get a blood investigation done for confirmation at least after ten days and if anything is diagnosed treatment can be planned accordingly. Hope this helps. Regards. </s>
