My bike key was feldown from my pocket as soon as I was taken it from one slum area which is with all snakes covers and dust. This is near by hospital ward. I have seen that there is a syringe plastic cover no neele in that. I had touched with slum place. I observed that I don't get any prick type. But my phobia regrading needle and also this is hospital. My doubt is that is there any needle in that slum area and without my presence my finger suppose touched with needle. So any risk on this situation. Can I get any std or HIV like hospital places specially touched with some thing in slum area. Does needles are thrown in slum area in hospital. Please help out me. What I suppose to do avoid for this type of fear regarding needles in hospitals. In my situation am I safe? Plsease help out me sir.
