I'm a bouncer at bar, there was a fight between two males I tried to separate them. One was bleeding in the head when I moved away putting my hand in his head and neck . I have some blood stains in my hand, I think the guy should have injured his head during fight and bleeding , my hand got a small knife cut (30 hours) before happened, no bleeding but the cut was open. I worried the guys blood come into contact and put myself in risk of hiv or any other stds. I know those guys are druggies...please advice me. A hiv test is needed. What's my risk level. I'm extremely panic. I don't have much blood in hand but some traces of blood. I washed later.
